Gary Knutson of McLaren is credited for McLaren's use of staggered length intake trumpets. By using two different intake tract lenghes, he was able to smooth a double-humped torque curve that had been characteristic of big Chevy V8's used previously in Can-Am. In any event, the staggered velocity stacks look so bitchin'!
@Wrulol: What an idiotic comment. Egads man, the velocity stacks were staggered because of the individual ports and airflow. Back in 1972, you would have been laughed right out of a racetrack because of such a stupid thing to say. Retarded? Methinks you are the retarded one.
@doowaditti Probably a few thousand HP, as I think the only rule for engines back then was they had to be reciprocating engines (i.e. with pistons - no turbines allowed). The turbo F1 motors in the '80s were around 1000 HP in race trim, up to 1300 for qualifying, and they were limited to 1.5 liters (90 cu in)! Just need to have it last a few hundred miles for the race duration.
@doowaditti well with the improvement of metals and engine building, 1000hp should be easily attainable, as well as plenty of torque. Not a few thousand hp, but having 1000hp in a light body is scary!
@doowaditti Probably they would be in the 1200-1400bhp range. A reciprocating engine under ten litres of displacement could easily produce 2500-3000hp, but that kind of power is unmanageable - too much stress over the transmission organs, and where in the world are you supposed to get the grip to keep a car that powerful on the track when cornering?
@clydeyello Also reliability with the motor is needed to win championships. It'd need rebuilds too frequently if it was pumping 2000hp. The proof's in the pudding with drag cars. :)
Gotta love those big block Chevrolets. Don't know what this one is, but the original McLaren Chevys were made by Reynolds Aluminum to the 427 Porcupine design. Most raced between 480 and 540ci, though late in the going, Denny Hulme tried one well beyond 600ci to get even with the Panzers. Massive power, but wouldn't live. From what I recall the different intake trumpets helped to further spread the broad power-band. I think it was short for top-end, long for the bottom, but maybe backwards.
@DaTwinkie405 Why have different length trumpets on different cylinders of the same engine though. They were staggered like that probably because if they were the same length each would be 'competing' for the same air with the next.
Look at the chimney stacks on that! Brilliant, daring design - real organic stuff , all going off at apparently wrong angles even though history proved it was incredibly right. None of the Mr. Boring engineers in F1 today would even DARE to carry off something like that.
Over the years, I have attended F1 races, Indy 500 13 years running, Nascar, NHRA, IHRA, Super Mods and the World of Outlaws Sprints. All of them have their own appeal. But they can't hold a candle to the heady days of CANAM. Anyone who was anything in the racing world took a kick at the cat, money was no object and rules were made to be tweaked.
It was a sad day when the series died, a victim of it's own technology.
I was fortunate enough to witness these cars race at Laguna Seca from 1971 thru the end in 1974(damn Porsche with 1100 hp in race trim),gotta love em.I do have to say that the greatest sound I have ever heard from a racing engine has to be a big block chevy Can-Am hammering out of the corkscrew.....we sat close in those days,unbelievable!!!!
Mosport was the track that we frequented here in Ontario for CAN AM & F1 back in the day. We used to sit on Moss corner which is a 3 part corner known as 5A-5B-5C. The big blocks would burble and blatt through MOSS and then all hell would break loose as they accelerated onto Andretti straight. The whole back end of the car would shudder and shake as the huge rear tires would make a valiant attempt to keep an unGodly amount of horsepower hooked up to the track.
@ridewithES They used big-block Chevys, all-aluminum. I don't know all the specs, but they were around 500 cubic inches, and made around 800 horsepower.
Is this the same M8 that sadly crashed at Brand Hatch recently after a complete brake failure going ino what looks like Druids bend? I hope the driver is now receovering well from this accident.

indy 500 greatest race come on really,it's a great race but for me not the greatest. i think the 24hr le mans is better atleast they can turn right aswell as turn left. hey and im only having alaugh so lets not get into a slgging match like some peps do.
THanks for your charming replies, which everyone can see here. If anyone had any doubt about you, those are gone now. The replies were meant for me, cool.
If you get so easily ticked off about such a little thing, i fear for your personal life. Cheer up a bit and discover the world.
actually they used even bigger engines in CanAm, McLaren used a 502 and possibly a 540 V8 from Chevy in the early 1970's
For all the great racing victories Ferrari fans brag about they never won nothing in Can-Am, whereas McLaren won 5 straight titles and 37 out of 43 races in 1967-1971. Also Ferrari never won the greatest motorrace in the world Indy500
Are guys like Helio Castro Neves, Tony Kanaan, Dario Franchitti, Dan Wheldon, Marco Andretti, Scott Dixon and Graham Rahal rednecks? Many of those raced in F3000 and F3.
The Indy 500 IS the greatest, most seen motorrace in the world and has the longest tradition. First run in 1911.
There is a vintage race every year at Elkhart Wi. They run everything that was ever made for racing, including these. Incredible watching the heyday of racing again and they aren't afraid to run hard. See old Mustangs, Cobras, F1s, Lotus' you name it. Every year the highlite a different manufacturer. It will be held the w/e of 7-19. check it out.thanks for the post, I can listen any time I want to hear one of these BEASTS.
I once read that the short ones were to give more torque at lower rpm, and the longer ones were to give maximum torque and hp at high rpm...however, i also once read that it was just because the trumpets were too wide to fit next to each other...
short tuned length makes more top end, long makes more bottom end, but u need same length on all inlets that why I wondered how 2 different lengths can be used.
maybe to give a cylinder bank two different characteristics as torque and high revolutions. if you only use long ones, you'll get more power from the bottom and if you only use short ones, you'll get more speed at the top of your revolutions. combining them means 2 cylinders at a bank have torque and the others have speed.
On a big block Chevrolet the intake ports in the cylinder heads are unequal length. The short stacks were matched up with the longer intake ports so that all 8 runners had equal net length.
That is exactly what the unequal length injectors try to fix!
If the injectors are equal length the you'll have 4 "torquey" cyls and 4 "top endy" like you said. That is bad since it's like having 2 different 4 cyl engines with different characters tied to the same crankshaft. Interesting, isn't it?
If I recall correctly, the uneven stacks are to help the motor have a wider tourqe range. Could be wrong but it's been many years since I've been around the old mechanical fuel injection systems.
actually ur the dumbass in the situation. The chassis were McClaren, the engine wasnt. Actualy they used the same block in the 1969 Corvette ZL1, thats cause it had the aluminum heads on it. Please do research before you post.
true, but I've read somewhere McLaren had urged Chevy to design an all aluminum V8 to be used in the Can-Am series. So it was primarily designed as a racing engine. Very few Corvettes came with it. Only 3 in fact. It was a costly option at the time. I think the ZL1 was ALL aluminum.
Anyway other teams used the big block Chevys too, but only McLaren designed a good enough car to harness all that power, that's where the true skill was.
hey shit for brains google can-am mclaren,and just look and see for your self before you start runnin your damn mouth...mclaren used zl1 aluminum 427 big block chevys in most of their cars,because the motor that were used in the 1969 zl1 camaro had can-am cast in the heads,and the block...so check your shit dumbass!!!
Wrong. They used blocks direct from Reynolds. I have one in my garage. There were three versions of it, basically three different weights. The ZL-1 was aimed at drag racing.
WTF if were gonna arguee arguee aboutmclaren vs lola or spomthing like that not if american iron beats rice rockets! i mean hell yea muscel cars i just cant get as exsited by jap cars even if tey are faster but Mclaren rules GO New Zealand!
Why are you coming on here, and being so negative, and narrow minded. If Porsches suck so badly, they'd be long gone, but not only have they stayeda round, but they have built one of the best reputations any car maker has ever made. Last I saw anyways, your precious Chrysler Corp, wasent doing too well, so looks like Chrylser/Dodge isnt exactly on their A game.
well chrysler is on their A game right now its the unions that aren't. Chrysler has all the big stuff coming out soon. By 2011, they will have dual clutch trannys. this year, the trucks all have link coil suspension. u don't know too much.
Chrysler will have dual clutch transmissions in 2011 huh? Not very impressive considering Audi, VW, Nissan, Porsche, and Mitsubishi are using them currently... Haha
ya know lets just say it's interest. you are interested in cars that are just fast and good. I like cars that are american, and have huge engines, and have lots of history, and are fast, and still look fast sitting in a parking lot. American cars are also alot better styled than foreign ones. And i don't care what's old news. the HEMI was apparently old news when chrysler was making HEMI's, but they basically ended up making the most powerful and sought after engine ever. You can't argue that.
That is a valid point, there aren't many street engines making that kind of power. We can agree to disagree over who made the best hemi, but hey I've never met a hemi I didn't like, haha.
Link coils suspension, and DTC, yeah they are about as ahead of the times as an amish cart. DTC was engineered in the 80's and has been used in base model cars like the GTI, and the Evo X. So nothing new. Also Link Coil suspension? maybe nice if you offroad alot, or you live in an area with bad roads, but not so good for takeoff,or towing. when the link squats the tires will become negative camber, resulting in excessive tire wear on the inner tire when towing or hauling. yeah nice.
yea the link coil is in the dodge ram. not sure about in the heavy duty ram though. Ya know, this whole thing has been aww we made it first waaah. well, same as the HEMI, you made the first, we made the best.
So, your arguement back is telling me I suck and blah blah blah... I do know what Challanger your talking about, and if you could actually count past 10 youd see I've said 600HP, which you estimate, which the new challanger does not have, which is at 425. Also the new challanger weights in at 4160lbs., 310lbs. more then the original challanger. So be glad you didnt take that bet. and FYI, that is the street version ofthe Porsche RSR.
Im not talking about the new challenger. Im talking about the 1970 challenger which does have 600 HP on the original 426 c.i. HEMI. and that is the street version as well.
the Porsche is 300HP @ 1850lbs. which not only has a HP/LBS ratio of 0.16, but is very nimble and the handling has still been compared to some modern day porsches, as to where the HEMI challanger is your estimated 600HP @ 3800LBS, giving it a 0.15 power to weight ratio. And not only has the HEMI applicant been done to "4 banger" euro cars, but your precious idea has also been used by Toyota. I love all cars around the world, but people like you ruin this hobby
People like Judge here are the same people that make the rest of the world hate us. nothing good ever came out of Texas. First Bush, now this arrogant bias prick. your right HP/per litre isnt everything, but Power to weight ratio is. ill give you the benefit of a doubt and go with your 600HP rating for the hemi.after everythign is said and done the porsche still beats teh HEMI challanger.
YOU SUCK, i hate u fagit go learn something i bet u don't even know anything about what HEMI challenger im talking about. Can u tell me the year the HEMI challenger is made? i bet ur thinking of the new one. ever heard of the 1970. im sorry that would crush a stupid porsche. porsches are for gay people anyway
Just a note for JudgeSteelflax, Mclaren have never been an engine manufacturer. I find it strange myself but I guess they'd rather outsource and be picky about what they buy. The BMW v12 they put in the F1 road car was genious.
Dude, europeans were using hemispherical heads over 40 years before Chrysler and Ford ever came out with theirs... I love American cars, but not because they are the best in the world.
Well, if history is any indication, I would argue Porsche had the best... The air cooled Porsches were a hemi configuration and they are the most successful competition cars of all time...
those suck when have i ever seen those out on the drag strip. u might say we don't turn at all, but u just don't be straight at all, those 4 bangers porsche makes sucks. if u want a best car, u gotta look at speed too not just drifting. those high rpm 4 bangers have little torque also. a mopar 440 six pack V8 (built ~68-71) had enormous amounts of torque since they reach full torque at like 3500 rpm. ur stupid ass cars dont accelarate like ours do. And don't get confused with factory ratings.
factory ratings in america are all drastically underated since we had things like insurance costs to worry about. your foreign numbers are all exagerated at least a little. a 426 HEMI was 425 HP rated by factory, but actually put out close to 600. im sorry but ur porsches don't mean shit against a hemi challenger (1970) and a 440 six pack (these aren't hemi) makes like 450 hp, compared to factory rated 375. YOU SUCK
Not only was the 1973 911 RSR faster than your Hemi challenger, but it did it with only 2.8 liters of air cooled power. Not to mention the car was built to race for 24 hours straight (and it won many times), so it was probably more reliable as well. 1.8 h.p./cubic inch for the Porsche, 1.4 h.p./cubic inch for the Hemi (assuming your claim of 600 horse power is correct).
and that 600 hp HEMI was the stock street HEMI built 64-71. the race HEMI for the same years was even more powerful. and nowadays, versions of this engine have been made pretty much standard for top fuel dragsters. these produce over 1000 hp. and i don't care about ur stupid h.p./cubic inch ratings cuz the fact is we still have more HP. u just use ur tiny engines as an excuse to why u can't have as much hp.
You don't know much about cars do ya? First of all, the Porsche engines I'm talking about are a flat 6 configuration. Second, top fuel engines are nothing like a stock hemi and they make around 8000 horsepower, not just "over 1000". Third, it doesn't matter if the other car has more power if it's slower. Fourth, there is more to performance than drag racing. Fact is an RSR would crush a hemi Challenger in all aspects of performance. Back to the main point, the best hemi's aren't from Chrysler.
sir, i don't care how many cylinders u have, ours are powerful. and those top fuel engines are not just stock HEMI's they are the original 426, stroked bored and souped up as much as possible. what is a street version of this engine? ur giving me all these racing engines. the street HEMI still had 600 hp. i want to know about a street version of a porsche. and there is more to racing than drifting also. YOU SUCK
First, 911 RSR's are road legal and are driven on the road. Second, no one is talking about drifting. I am referring to all around performance (handling, braking, as well as accelerating). There isn't one aspect of performance where a 1969-1970 Challenger can touch the RSR.
The Porsche makes more power per cubic inch, is faster, more economical, and more reliable. Better engine, better car. Quit with the ignorant arguments.
no im not quitting u are the one who needs to quit the comments, they didnt even make challenger in 1969. we already established hp/c.i. doesn't matter. Chrysler has more hp. fact. and 911 rsr was not made to be a production car was it? and i need a vid of this car in a drag race. find me that. i might just belive u then.
No, top fuel engines share NO parts with a stock hemi. The block is completely different, it is aluminum and doesn't have water jackets. Also YOU said h.p./c.i. didn't matter, I argue it is a crucial measure of a high performance engine. They sold over 100 RSR's, it was a production car. I don't need a video to know that a car with a lower power to weight ratio is slower, look at the statistics. So are you seriously saying that the Challenger is a better sports car than the RSR?
selling 100 is hardly a production car. and the block is the same block measurement wise, maybe its aluminum and no waterjackets, but its based off the 426 HEMI, sorry. and hp/ci does not matter, if u have more hp u have more hp, i don't care how many ci it is. i have more hp.
Whether or not you consider it a "production car" it is street legal, people drive them on the street, and is faster than your Challenger. Also, you can have 600 horsepower, you're STILL SLOWER! I'm pretty sure that is more important. And yes, the top fuel engines are BASED off the Chrysler 426 only because the rules dictate that the teams cannot design their own superior block and valvetrain arrangement, NOT because they Chrysler hemi is the greatest engine ever.
Of course H.P./C.I. matters, how else are you going to compare two different engines of vastly different size? Following your logic the best engine in the world must be the Wartsila-Sulzer RTA96-C, after all it has the most power! Never mind that the crankshaft alone weighs more than 200 of your precious Challengers.
ok so its good to have a light engine but im talking about power is power. if i want i could put a train engine in back of my truck. that ain't doing nothing. at a certain point (maybe 650 ci) engine is too big past that.

Look at the specifications! The RSR has a better power to weight ratio and a higher top speed. Not to mention far better braking and handling. What more proof do you need? What about the Boss and the SS? The RSR would smoke both of them too...
proof please, any body can tell me there tuner car can beat a true muscle car. gimme a video of its best drag time u can find, ill give u a challenger vid (or 2).
God you're fuckin stupid... Videos don't prove shit, there could be a ton of modifications done to either car. Look at the cars specifications stock vs. stock. Otherwise it is pointless to even compare the two cars. I don't need a video of someone getting punched in the face to know it hurts, common sense should be applied here. Better power to weight ratio=faster car. Just because it's a muscle car doesn't make it invincible.
You seem like an unintelligent person by saying what you say.
First of all, Obama is no commy.
Second of all, everyone knows american built cars are crap compared to european or asian cars. Only the last few years they have improved.
This discussion does not even belong to this video, so please before you reply next time, learn your facts a bit more and don't reply when you are emotional.
I wish you knew anything about cars pre-1985 you shitass. those are real cars. my 1972 Ford F250 is amazing. Yeah it just has a big ol' american V8. But man its a classic american V8 masterpiece and you can't beat that. may not be as fast as you're supercars, but they sound great, look great, pick up chicks, and attract attention.
As for Obama, i don't know how you can say he's not at least socialist with all this government bullshit. GO SOUTH!
in modern endurance racing (starting with group C in the early 80's) the cars that could make the most reliable power using the least amount of fuel usually won
a reliable 100hp per litre horsepower with a wide torque powerband requires a heck of a lot more advanced engineering than some 50's pushrod design not producing half that for the same displacement amount
Gary Knutson of McLaren is credited for McLaren's use of staggered length intake trumpets.

Are guys like Helio Castro Neves, Tony Kanaan, Dario Franchitti, Dan Wheldon, Marco Andretti, Scott Dixon and Graham Rahal rednecks? Many of those raced in F3000 and F3.
The Indy 500 IS the greatest, most seen motorrace in the world and has the longest tradition. First run in 1911.
You're the redneck. A spritual redneck.

is it running open headers??? sounds like it. either that or it has a sloppy idle from just being started and not being warmed up yet. or both.
localdu 2 years ago
They are open headers. The sloppy idle comes from the radical lift & duration of the camshaft.

why different length trumpets?
tpvalley 2 years ago
I once read that the short ones were to give more torque at lower rpm, and the longer ones were to give maximum torque and hp at high rpm...however, i also once read that it was just because the trumpets were too wide to fit next to each other...
but that's just what i read...
M3addicted 2 years ago
short tuned length makes more top end, long makes more bottom end, but u need same length on all inlets that why I wondered how 2 different lengths can be used.
tpvalley 2 years ago
maybe to give a cylinder bank two different characteristics as torque and high revolutions. if you only use long ones, you'll get more power from the bottom and if you only use short ones, you'll get more speed at the top of your revolutions. combining them means 2 cylinders at a bank have torque and the others have speed.
Oldenways 2 years ago
On a big block Chevrolet the intake ports in the cylinder heads are unequal length. The short stacks were matched up with the longer intake ports so that all 8 runners had equal net length.

Etorresdeltoro 2 years ago
That is to compensate for the unequal length intake runners on the big block Chevy cyl head.
It had 2 "short" and 2 "long" intake runners per head and this injector design was to compensate for that.
Etorresdeltoro 2 years ago
That makes more sense than having unequal lengths so some cylinders r top endy and some torquey!
tpvalley 2 years ago
That is exactly what the unequal length injectors try to fix!
If the injectors are equal length the you'll have 4 "torquey" cyls and 4 "top endy" like you said. That is bad since it's like having 2 different 4 cyl engines with different characters tied to the same crankshaft. Interesting, isn't it?

but yes, that would be like having unbalanced carbs.....shit!!

07speed3guy 1 year ago
@Boyracer5500
true, but I've read somewhere McLaren had urged Chevy to design an all aluminum V8 to be used in the Can-Am series. So it was primarily designed as a racing engine. Very few Corvettes came with it. Only 3 in fact. It was a costly option at the time. I think the ZL1 was ALL aluminum.
Anyway other teams used the big block Chevys too, but only McLaren designed a good enough car to harness all that power, that's where the true skill was.

ya know lets just say it's interest. you are interested in cars that are just fast and good. I like cars that are american, and have huge engines, and have lots of history, and are fast, and still look fast sitting in a parking lot. American cars are also alot better styled than foreign ones. And i don't care what's old news. the HEMI was apparently old news when chrysler was making HEMI's, but they basically ended up making the most powerful and sought after engine ever. You can't argue that.
JudgeSteelflax 3 years ago
That is a valid point, there aren't many street engines making that kind of power. We can agree to disagree over who made the best hemi, but hey I've never met a hemi I didn't like, haha.
borde049 3 years ago
im just saying american muscle cars have more value generally, and the 426 HEMI is probably the most sought after engine
JudgeSteelflax 3 years ago
Link coils suspension, and DTC, yeah they are about as ahead of the times as an amish cart. DTC was engineered in the 80's and has been used in base model cars like the GTI, and the Evo X. So nothing new. Also Link Coil suspension? maybe nice if you offroad alot, or you live in an area with bad roads, but not so good for takeoff,or towing. when the link squats the tires will become negative camber, resulting in excessive tire wear on the inner tire when towing or hauling. yeah nice.
blacdout96 3 years ago
yea the link coil is in the dodge ram. not sure about in the heavy duty ram though. Ya know, this whole thing has been aww we made it first waaah. well, same as the HEMI, you made the first, we made the best.
JudgeSteelflax 3 years ago
So, your arguement back is telling me I suck and blah blah blah... I do know what Challanger your talking about, and if you could actually count past 10 youd see I've said 600HP, which you estimate, which the new challanger does not have, which is at 425. Also the new challanger weights in at 4160lbs., 310lbs. more then the original challanger. So be glad you didnt take that bet. and FYI, that is the street version ofthe Porsche RSR.
blacdout96 3 years ago
Im not talking about the new challenger. Im talking about the 1970 challenger which does have 600 HP on the original 426 c.i. HEMI. and that is the street version as well.
JudgeSteelflax 3 years ago
with how meny mods?
lamage89 3 years ago
the Porsche is 300HP @ 1850lbs. which not only has a HP/LBS ratio of 0.16, but is very nimble and the handling has still been compared to some modern day porsches, as to where the HEMI challanger is your estimated 600HP @ 3800LBS, giving it a 0.15 power to weight ratio. And not only has the HEMI applicant been done to "4 banger" euro cars, but your precious idea has also been used by Toyota. I love all cars around the world, but people like you ruin this hobby
blacdout96 3 years ago
People like Judge here are the same people that make the rest of the world hate us. nothing good ever came out of Texas. First Bush, now this arrogant bias prick. your right HP/per litre isnt everything, but Power to weight ratio is. ill give you the benefit of a doubt and go with your 600HP rating for the hemi.after everythign is said and done the porsche still beats teh HEMI challanger.
blacdout96 3 years ago
YOU SUCK, i hate u fagit go learn something i bet u don't even know anything about what HEMI challenger im talking about.

borde049 3 years ago
those suck when have i ever seen those out on the drag strip. u might say we don't turn at all, but u just don't be straight at all, those 4 bangers porsche makes sucks. if u want a best car, u gotta look at speed too not just drifting. those high rpm 4 bangers have little torque also. a mopar 440 six pack V8 (built ~68-71) had enormous amounts of torque since they reach full torque at like 3500 rpm. ur stupid ass cars dont accelarate like ours do. And don't get confused with factory ratings.
JudgeSteelflax 3 years ago
have u seen a stock hemi vs a stock porche from the same time drag? youd be surprised
say a 1970 dodge challenger hemi vs a stock porsche 911 drag ha u would be left in the dust!
lamage89 3 years ago
That's not what I'm talking about...
borde049 3 years ago
factory ratings in america are all drastically underated since we had things like insurance costs to worry about. your foreign numbers are all exagerated at least a little. a 426 HEMI was 425 HP rated by factory, but actually put out close to 600. im sorry but ur porsches don't mean shit against a hemi challenger (1970) and a 440 six pack (these aren't hemi) makes like 450 hp, compared to factory rated 375. YOU SUCK
JudgeSteelflax 3 years ago
Not only was the 1973 911 RSR faster than your Hemi challenger, but it did it with only 2.8 liters of air cooled power. Not to mention the car was built to race for 24 hours straight (and it won many times), so it was probably more reliable as well. 1.8 h.p./cubic inch for the Porsche, 1.4 h.p./cubic inch for the Hemi (assuming your claim of 600 horse power is correct).
borde049 3 years ago
u haven't proved anything to me yet until i see it win in a drag race. how bout torque ratings on that 2.8L four crapper?
JudgeSteelflax 3 years ago
and that 600 hp HEMI was the stock street HEMI built 64-71. the race HEMI for the same years was even more powerful. and nowadays, versions of this engine have been made pretty much standard for top fuel dragsters. these produce over 1000 hp. and i don't care about ur stupid h.p./cubic inch ratings cuz the fact is we still have more HP. u just use ur tiny engines as an excuse to why u can't have as much hp.
JudgeSteelflax 3 years ago
You don't know much about cars do ya? First of all, the Porsche engines I'm talking about are a flat 6 configuration. Second, top fuel engines are nothing like a stock hemi and they make around 8000 horsepower, not just "over 1000". Third, it doesn't matter if the other car has more power if it's slower. Fourth, there is more to performance than drag racing. Fact is an RSR would crush a hemi Challenger in all aspects of performance. Back to the main point, the best hemi's aren't from Chrysler.
borde049 3 years ago
sir, i don't care how many cylinders u have, ours are powerful. and those top fuel engines are not just stock HEMI's they are the original 426, stroked bored and souped up as much as possible. what is a street version of this engine? ur giving me all these racing engines. the street HEMI still had 600 hp. i want to know about a street version of a porsche. and there is more to racing than drifting also. YOU SUCK
JudgeSteelflax 3 years ago
First, 911 RSR's are road legal and are driven on the road. Second, no one is talking about drifting. I am referring to all around performance (handling, braking, as well as accelerating). There isn't one aspect of performance where a 1969-1970 Challenger can touch the RSR.
The Porsche makes more power per cubic inch, is faster, more economical, and more reliable. Better engine, better car. Quit with the ignorant arguments.
borde049 3 years ago
no im not quitting u are the one who needs to quit the comments, they didnt even make challenger in 1969. we already established hp/c.i. doesn't matter. Chrysler has more hp. fact. and 911 rsr was not made to be a production car was it? and i need a vid of this car in a drag race. find me that. i might just belive u then.
JudgeSteelflax 3 years ago
No, top fuel engines share NO parts with a stock hemi. The block is completely different, it is aluminum and doesn't have water jackets. Also YOU said h.p./c.i. didn't matter, I argue it is a crucial measure of a high performance engine. They sold over 100 RSR's, it was a production car. I don't need a video to know that a car with a lower power to weight ratio is slower, look at the statistics. So are you seriously saying that the Challenger is a better sports car than the RSR?
borde049 3 years ago
selling 100 is hardly a production car. and the block is the same block measurement wise, maybe its aluminum and no waterjackets, but its based off the 426 HEMI, sorry. and hp/ci does not matter, if u have more hp u have more hp, i don't care how many ci it is. i have more hp.
JudgeSteelflax 3 years ago
Whether or not you consider it a "production car" it is street legal, people drive them on the street, and is faster than your Challenger. Also, you can have 600 horsepower, you're STILL SLOWER! I'm pretty sure that is more important. And yes, the top fuel engines are BASED off the Chrysler 426 only because the rules dictate that the teams cannot design their own superior block and valvetrain arrangement, NOT because they Chrysler hemi is the greatest engine ever.
borde049 3 years ago
Of course H.P./C.I. matters, how else are you going to compare two different engines of vastly different size? Following your logic the best engine in the world must be the Wartsila-Sulzer RTA96-C, after all it has the most power! Never mind that the crankshaft alone weighs more than 200 of your precious Challengers.
borde049 3 years ago
ok so its good to have a light engine but im talking about power is power. if i want i could put a train engine in back of my truck. that ain't doing nothing. at a certain point (maybe 650 ci) engine is too big past that.

not when displacement is taken into account
in modern endurance racing (starting with group C in the early 80's) the cars that could make the most reliable power using the least amount of fuel usually won
a reliable 100hp per litre horsepower with a wide torque powerband requires a heck of a lot more advanced engineering than some 50's pushrod design not producing half that for the same displacement amount
or was they too advanced for you to understand?
