If you fucking know about rotaries and seen them in action, you would know that if you ever went against a 4 rotor, it's like going against the supernatural, you won't win.
Rotaries are great engines. Americans are generally horrible in maintaining their vehicles, and Rotary engines do not like to be neglected. Oil changes need to be routine, and pin-point. Flush other fluids regularly, change the lead & trailing spark plugs regularly, and a stock Rotary will last for a long time. The more you modify them, they will fail (apex seal failure is more common). But if you know how to break the engine down & rebuild, it's all good.
@mtech20 yeh in theory but in reality they are shit ,fuel economy is rubbish and you burn oil like a two stroke motor so emissions not so good i owned a suzuki re5 ok that was a long time ago and things have moved on but rotarys are still flawed ,thats why only mazda are stupid enough to make them ,some motors still used in aircraft drones etc also they cheat with the actual cc they measure them in , my suzook was rated as a 500cc but infact was 1500cc and a slow 1500 motor at that
i love the power to weight ratio and low vibration.
the problem i'm addressing is the combustion seal. there are no piston rings.. but there are components equivalent to piston rings.
the seal at the point of the rotor has an incessant problem. the groove wares out. it can't slide into its grove when it comes in contact with the combustion chamber wall it goes wam!!! mostly happens when you take your foot off the gas too. also. r-2 has oil injected into the carb exactly like a 2-cycle.
wankels are great. but i guess everyone who owns one is dead cause when you take your foot off the gas at high speed to go arround a tight turn, it inevidably lockes the engine up and the tires skid and theres no traction arround a high speed turn and ytou smash into the object (the object that the turn in the road was going arround).. at high speed and your instantly lkilled or the vehicle is destroyed at the verry least. lol
@loveshark1m The turning capabilities of a car have nothing to do with the engine in the front and what you are talking about only occurs when then driver can't drive, I've been in a rx7 that takes corners faster then any other car. If you can't handle a car that responds when you do something then yeah, don't buy a rotary.
@Pinkishbass91 actually I gotta say, you do get more traction when there is the right amount of power going to the wheels for the speed your travelling, that's why your taught not to coast in clutch and manual gearbox cars, limited steering ^^
@loveshark1m You seem to be inhaling exhaust fumes. I owned an original 1971 RX-2 Coupe and loved the car. Wankels had, do not know if they fixed the problem, a seal problem and were prone to being blown. I had to rebuild the motor three times in 110 thousand miles. The performance was worth it. I wish I had kept that car, sold it in 1991
@kabreu54 yes they did fix the problem, you would of had the 10A if it was standard which were properly terrible. 12A's weren't much better the 13B's only have the problem if mistreated some of the newer ones a pretty much indestructible.
@Pinkishbass91 I had the 12A's. They were sure fun when they worked and scared the hell out of the neighbors when they backfired. I somehow always managed to turn off the car with a rich mixture in the chamber! :^)
@fateephat that isnt true. Whoever owned it was an idiot or bought it preowned from an idiot that didn't know that you have to add oil every time you drive it. Cause it burns oil to lubricate the apex problem is when the oil gets low now it stops pumping oil and you blow seals so its not the engines fault its the stupid owner that wants to be a cheap ass and not buy oil. Also you have to rev on these engines to blow out the carbon since they burn oil you build carbon around the seals.
heh, no. you take it apart to clean the housing... =) as you should, since it's super easy on any rotary.. say compared to my other motor, an SR20DET which is an enormous pain.
@Pinkishbass91 yep. take the 1991 lemans winner for example. The FIA took the mazda car and publicly dismantled the motor to show everyone that even after 24 hours of some of the hardest racing your can put a car through the engine didn't have hardly any wear or tear. And then they got banned after that. Formula 1 bans rotary engines so does the US midget league after the 1989-1990 wins from rotary powered midgets. Also Rx-7s have won more races in US racing events then any other car can claim.
@loveshark1m So do that...dump the clutch feather throttle and counter steer...and the motor would not lock up the wheels....Unless it siezed. The differencial would have control over that. Miatas can take corners at like 100....... :)
People who say American cars are good have never driven a German car. Try BMW or Mercedes and you'll change your mind :) American cars are ugly and at the same time have ridiculously high fuel consumption. Furthermore, German cars provide far more comfort when driving =)
Why does every stereotype American Cars? No, they aren't only good in a straigh line. Yes, some aren't very good handling and cornering, but there are plenty of mean machines out there that can kick ass regardless if it's a straigh line or not. I love cars for what they are and what they can do. Not what they look like, or what others think of them.
@ploppercon Oh really? Is that why your the only person to say anything to that comment, which by the way, is a week old? Oh, and I'm sorry to hear your birth certificate was an apology from the condom company :'(
@conutach All 13b's are 2 rotors that is why they are 13b's lol. :) 1.3 L twin rotor 2.0L 3 rotor 1.6L twin rotor 2.6L 4 rotor those are the only sizes I know of not that there aren't others though. And there are several designs for each the 13b, 12a, 13b-rew, 13b renisis, r26b(which this is the mazda motor that I think only 26 where ever made), scoot 26b extreme rotaries is designing a 26b, magic 26b.
Ummmm... Really, the Corvette ZR1 only good in a straight line? I think it's 7:19.63 lap time on Nurburgring begs to differ. That is better than the GT-R, Porsche and many European cars that are so superior. C'mon quit being close-minded, we're talking about cars who cares where there from or anything. Btw just because Jeremy Clarkson said the ZR1 is made of plastic doesn't mean it's true. It's actually fiberglass and Carbon Fiber. P.S. the ZR1's time is 8 seconds off of the Gumpert Apollo's...
@Tj1056 Grats bro, you just listed the top five cars off Wiki. Now allow me to perform some internet-Fu. Every car you listed is over $180,000, with the Gumpert topping out at close to $400k. If you compare the Gumpert to the ZR1, then the Gumpert will cost you $35,800 to go ONE SECOND faster than the ZR1. There's a $180,000 difference between the Porsche and the ZR1, for one second faster.
Simply comparing bang for the buck, Americans do it about as fast for a lot less money.
@Tj1056 If the cars are meant for racing? Then your 10k car was a better purchase, and a better car. Spread out the difference more. If the car costs a million dollars and is supposed to be fast, but gets beat by a $10,00 car, which is better?
@Tj1056 Okay, take a look at the specs of the cars you named. Also the Radicals are NOT sports production cars. Let's evaluate the pricing as well, the ZR1 is 100k not bad for a car holding one of the fastest time around the ring, for way less of the price. Also, don't be too confused, the Gumpert Apollo has downforce with a wing and most likely a front diffuser. The ZR1 has no wing. Porsche also has a wing. They can take turn faster. Still beats a lot of cars and oh wait, it's American.
@Tj1056 So wait, that's looks like a normal production car to you? A better competitor for that would be the Arial Atom. It may be cheaper, it's also probably half the weight. Not a good comparison, that's like comparing a race between a heavyweight boxer, and an olympic runner.
@Ah1692 sorry we were talking about production cars?... I like when people like you try to change the whole concept of the arguement to try to make themselfs look less stupid...
@Tj1056 Actually, people like you are not paying attention to the argument and speaking out with ignorance. Before you said about the Donkervoort D8, I said the Radical is not a production car. It's just obvious, something half the weight and looks like a go-kart would be was faster than a car that's really heavy and is a regular CAR. Point still stands 100-120k will get you a 7:19 around the Nurburgring, also stands American cars know what they're doing.
@mailmanbam in the 70's GM was R&D'ing the rotary engine for use in the Sting Ray body vette using a 4rotor.... they couldnt figure out a way to lubricate the seals or find a material strong enough and kept breaking them after about 100miles of use.
@CorvetteCoonass Maybe not but they definitely have seen a Porsche or BMW in action... or a Ferrari, an Alpina, maybe some Lamboghinis, Paganis and Köenigseggs too...
With the "American cars are better" quote, if you like any quality from your car, you ain't going to buy that plastic crap (awful interior & bodywork if it's a "vette"), for the speed, maybe, but then I still wouldn't want one, as there are many more desirable things to own.
@Pinkishbass91 im not a fan of american cars either, especially the vette....but recently saw a vid of the ZR1 going around the Nuremberg ring pulling over 2 G's in the corners and taking 1 corner at 187MPH....pretty damn good for a "typical" american car
@RyanK733 imports are going to be better yes, because only the good cars are imported... look at the entire range of cars from any country...its all 99% junk
@GrandMoffSilvey Yes, Its the way 4 rotors are made in terms of angles so that the spark plugs fire 1,3,2,4 Unlike some who think it works like sort of like a piston engine with the center pair of rotors being on the exact same angle, while the outside are the same. This was tested i believe and it ripped itself apart.
actually it is very popular in the states as well as here in Germany and I have watched almost every episode of top gear. I dont agree with there view of American cars but it is a fun show to watch. Even when an American car beat the veyrons top speed all they did was show pictures and cut on it, instead of actually testing it.They dont even try to hide their bias. And there are so many great American cars that naming them would be pointless. If you cant see that your just ignorant and biased.
@MrAngryRedneck The Ultimate aero (I believe you're talking about) had no handling compared to the veyron, it was designed just to go fast, you call that a car of the same class, thats like comparing a drag car to a F1 and saying 'er huh its faster'. The aero also used way to much road to get to that speed, the new veyron supersport is faster, requires less road, and CAN go around corners.
@MrAngryRedneck The only good car to come out of USA is Fords GT40 it is a good car, but compared to the other cars it competes against, is sluggish and dopey.
@Pinkishbass91 Well thats where your wrong, the Aero is proven to have excellent handeling and it was able to beat the top speed on a public road not on the closed private track. not to mention the aero costs a fraction of the price and has half the cylinders. The newer aero is rumored to go 270 but has yet to be tested to that speed. not to mention what car has the record for a FULL lap at the nurburgring the viper acr (also holds lap record at laguna seca). the ZR1 & Z06 are also great cars.
@MrAngryRedneck the viper is 6th on the list for the nuburgring its been beaten by, Radical SR8 LM, Radical SR8, Gumpert Apollo Speed, Donkervoort D8 RS, Porsche 911 GT2 RS, Donkervoort D8 RS (Older). So no not the fastest, and the reason the Aero hasn't been tested for that speed is because the isn't enough straight road for it to get to that speed, the track they tested the veyron supersport on, had a shorter straight then the road the Areo was tested on.
@Pinkishbass91 He means production car. Viprer ACR is the fastest production car on the nurburgring. Those other cars are like super-special, not every customer can buy one. Not sure if the 2012 GTR, ZR-1, or new 911 turbo has beat it's time yet, but the fact still remains. Every great car can be eclipsed by an american car. If you don't admit that, you're biased. I am a tuner, and an import guy, but for you to not think american cars are just as good/better, is fawked.
@519Garage I checked and the times i saw where for production cars all of them. You're taking me the wrong way, I didn't say american cars aren't good, they're still good cars, its just nearly everyone i see there is always some stupid problem with it that they fucked up when theres a European, Japanese car or whatever of the same class that is a lot cheaper and a lot better.
@MrAngryRedneck They where going to test the areo on the same track they tested the veyron supersport on, but didn't because there was not enough room........The straight is 5 miles long....
@Pinkishbass91 Actually, I said A FULL lap around the ring. The cars you mentioned did the short lap, while the time difference between the short lap and the full lap would not make up for the difference it would be close. not to mention they are all built on purpose built track cars not road cars turned into track cars.
@Pinkishbass91 As for the Aero, They would not allow the Aero on the track because it is VW groups private track and it was certainly not in their intrest. Not that it would need it since it did it with an amature driver with no racing exp. on a 4 mile stretch of rough paved public road 4 miles long with a dog leg bend in the middle which he had to navigate at speeds around 210mph. unlike the test track for the veyron ss which has a straight of 5.6 miles
@Pinkishbass91 If thats not enough, wait till the end of this year when the next generation Aero starts shipping out with 1350hp and a reported top speed of 275mph (plus a MUCH more refined look than the current generation) google "2012 SSC Ultimate Aero II" you find There is an excellent artical on topspeed,com I'd put up a link but you know how youtube is all gay about that. While the top speed is yet to be officially recorded it was built to beat the ss so let the rivalry begin!
@SypherDubstep Also if you think about, in a rotary, there are more ignitions per revolution of the eccentric shaft, and there are more revolutions per minute as rotary's rev higher. Apposed to the piston engine which does one ignition every 2 revolutions (4 strokes) of the crank shaft and isn't rotating as much.
@SypherDubstep This is not the one used in the RX8 of course, the RX8 only has 2 rotors.
And it is less efficient as it does not burn all the fuel and air mixture, as in a Piston Engine. The RX8 was designed (I'm not exactly sure how) to meet the emissions standards and be more efficient then the previous series 8 RX7 as well as be a lot safer. Thus making it slightly slower I'd imagine.
The 4 rotor spoke for itself, with the win of 1991 le mans series... It was immediately banned afterwards for unfair power/weight advantages. Type in mazda 787b at the top of the page
@ galacticoAR. Oops. I meant to say fully built and turbocharged. In its n/a form, the 4 rotor nets from high 400hp- 600hp. Its all about the parts and tunning
@FIREMANDRE29 you serious? i didn't think the tourque curve would be that good, maybe not a veyron, i'd like to see it against a corvette zr1, see who can put the power down
@Pinkishbass91 Geeza, i ain't american but even i have to admit they do make some excellent cars, say what you want , do want you want, the corvette zr1, viper acr, ultimate aero tt, saleen s7 all speak for themselves
@MrAngryRedneck No need to get personal, I'm talking about a product no the people you know. Name a good Ever watched top gear? oh thats right it's not popular over there, says enough.
Germany systematically uses torture and murder to silence any opposition. Some of the murders known to the public: Uwe Barschel, Jürgen Möllemann, Heiner Gehring, Martina Pflock, Tron, Karl Koch, Bernd Seiffert, Kirsten Heisig, Fritz Bauer.
My brother Markus Bott had been tortured during 5.5 years by the German BND. He was assassinated on 11.7.09 because of our homepage.
German snitchers are following me on youtube and immediately flag my postings.
think like this: in each rotor you have 3 face for combustion, its like having 3 pistons in the same cilinder, if you multiply by 4 (the # of rotors) you''l get the equivilant of a v12 in the same space as inline 4 cilinder engine! i call that OWNAGE! add the same turbo harge used in v12 and you'll get PWNAGE!! all that in could fit in 2hp citroen or on a big bike!! very dangerous technology if you ask me!
@eddie8080 divide? there nothing to divide! eccentric shaft? it doesnt matter you have 3 combustion faces in each rotor! the eccentric shaft doesn't influence it anything... you still have 3 combustion faces for each rotor! and this a 4 rotor! therefore 3x4=12combustion faces=12cilinders=V12 now tell me where does the eccentric shaft enter in this function??
@bazengao The eccentric shaft (equivalent to a crankshaft) enters into this because it turns at 3 times to the rotor's 1. So at 3000 eccentric shaft RPMs the rotors only turn 1000RPM.
Also, the 2.6L 4 rotor is = to a 5.2L V8. With 4 rotors you get 4 combustions per revolution of the eccentric shaft displacing 2.6L. This is directly comparable to a 5.2L V8 that also has 4 combustions per revolution of the crankshaft displacing 2.6L. Remember 4 stroke piston engines only fire every other rev.
@Warblade118 so does that mean a 1.3 renesis is equil to a 2.6? I had an 04 rx8 and it was gutless, what are these engines outter dimensions similar to? a 4 cylinder?
@firechicken76 For a comparison of displacement most racing body's view the rotary as double its "rated" displacement when comparing it to a piston engine. So yes, a 1.3L 2 rotary is = to a 2.6L 4cly piston engine in both displacement used in combustion per revolution of the crankshaft (or e-shaft) and number of power strokes (impulses) per revolution of the crank or e-shaft. The 13B in the RX7 weights about 250lbs, is a little shorter but a bit wider than a 4cly. I'm not sure about the RX8.
@Warblade118 13b renesis i think is the same basic size as the older 13b, it's just aluminum instead of iron. I hate how everyone says " its only a 1.3 and has 238hp"
@firechicken76 Yeah, it's very misleading isn't it? I looked into it a bit more and found the renesis does weigh about 250lbs (dry) so in reality its not much lighter than a typical 4 cly engine, its outer dimensions are just a little smaller. But when you think of is as = to a 2.6L 4cly its 238HP makes alot more sense. And is only about 91HP/L which pretty unremarkable compared to alot of modern 4cyls.
One year, an RX-7 production model challenged corvette performance. The next year or two, it went out of production. The RX-8 seems too weak to call a sports car. What is going on?
Ever driven one? go to the dealer and take one for a spin.
I just bought one, and it BLOWS my GTI away! I just spent 30 mins trying to figure out how to change the dash from kilometers to mph. 100kph = 60mph. It was already set to mph - it was just me not used to cruising in 3rd gear at 100mph! Perfect 50/50 and light weight. 10,000rpm. And really nice seats. seriously. go test drive one before you say its not a sportscar.
Oh, and its a four door that fits both of my kids.
@kassenz 1. 100kph = 62mph. 2. Driven which? 3.I don't care if a car revs to 1 rpm or 1,000,000 rpm: I want usable power. 4. I don't consider ANY VW to be a sports car. Sporty not = sports car. I'll look at some specs again, maybe something's changed. I am glad you like your new car. Good luck with it!

Ummmm... Really, the Corvette ZR1 only good in a straight line? I think it's 7:19.63 lap time on Nurburgring begs to differ. That is better than the GT-R, Porsche and many European cars that are so superior. C'mon quit being close-minded, we're talking about cars who cares where there from or anything. Btw just because Jeremy Clarkson said the ZR1 is made of plastic doesn't mean it's true. It's actually fiberglass and Carbon Fiber. P.S. the ZR1's time is 8 seconds off of the Gumpert Apollo's...

@Tj1056 Grats bro, you just listed the top five cars off Wiki. Now allow me to perform some internet-Fu. Every car you listed is over $180,000, with the Gumpert topping out at close to $400k. If you compare the Gumpert to the ZR1, then the Gumpert will cost you $35,800 to go ONE SECOND faster than the ZR1. There's a $180,000 difference between the Porsche and the ZR1, for one second faster.
Simply comparing bang for the buck, Americans do it about as fast for a lot less money.

@Tj1056 If the cars are meant for racing? Then your 10k car was a better purchase, and a better car. Spread out the difference more. If the car costs a million dollars and is supposed to be fast, but gets beat by a $10,00 car, which is better?
reddog418 7 months ago
@reddog418 more like a 40k corvette...
Tj1056 7 months ago
@Tj1056 Okay, take a look at the specs of the cars you named. Also the Radicals are NOT sports production cars. Let's evaluate the pricing as well, the ZR1 is 100k not bad for a car holding one of the fastest time around the ring, for way less of the price. Also, don't be too confused, the Gumpert Apollo has downforce with a wing and most likely a front diffuser. The ZR1 has no wing. Porsche also has a wing. They can take turn faster. Still beats a lot of cars and oh wait, it's American.

@Ah1692 Donkervoort D8 RS beat it also... and its cheaper...

@Tj1056 So wait, that's looks like a normal production car to you? A better competitor for that would be the Arial Atom. It may be cheaper, it's also probably half the weight. Not a good comparison, that's like comparing a race between a heavyweight boxer, and an olympic runner.

@Tj1056 Actually, people like you are not paying attention to the argument and speaking out with ignorance. Before you said about the Donkervoort D8, I said the Radical is not a production car. It's just obvious, something half the weight and looks like a go-kart would be was faster than a car that's really heavy and is a regular CAR. Point still stands 100-120k will get you a 7:19 around the Nurburgring, also stands American cars know what they're doing.

GrandMoffSilvey 1 year ago
@GrandMoffSilvey Yes, Its the way 4 rotors are made in terms of angles so that the spark plugs fire 1,3,2,4 Unlike some who think it works like sort of like a piston engine with the center pair of rotors being on the exact same angle, while the outside are the same. This was tested i believe and it ripped itself apart.
Pinkishbass91 1 year ago
actually it is very popular in the states as well as here in Germany and I have watched almost every episode of top gear. I dont agree with there view of American cars but it is a fun show to watch. Even when an American car beat the veyrons top speed all they did was show pictures and cut on it, instead of actually testing it.They dont even try to hide their bias. And there are so many great American cars that naming them would be pointless. If you cant see that your just ignorant and biased.
MrAngryRedneck 1 year ago
@MrAngryRedneck The Ultimate aero (I believe you're talking about) had no handling compared to the veyron, it was designed just to go fast, you call that a car of the same class, thats like comparing a drag car to a F1 and saying 'er huh its faster'. The aero also used way to much road to get to that speed, the new veyron supersport is faster, requires less road, and CAN go around corners.
Pinkishbass91 1 year ago
@MrAngryRedneck The only good car to come out of USA is Fords GT40 it is a good car, but compared to the other cars it competes against, is sluggish and dopey.
Pinkishbass91 1 year ago
@Pinkishbass91 Well thats where your wrong, the Aero is proven to have excellent handeling and it was able to beat the top speed on a public road not on the closed private track. not to mention the aero costs a fraction of the price and has half the cylinders. The newer aero is rumored to go 270 but has yet to be tested to that speed. not to mention what car has the record for a FULL lap at the nurburgring the viper acr (also holds lap record at laguna seca). the ZR1 & Z06 are also great cars.
MrAngryRedneck 1 year ago 2
@MrAngryRedneck the viper is 6th on the list for the nuburgring its been beaten by, Radical SR8 LM, Radical SR8, Gumpert Apollo Speed, Donkervoort D8 RS, Porsche 911 GT2 RS, Donkervoort D8 RS (Older). So no not the fastest, and the reason the Aero hasn't been tested for that speed is because the isn't enough straight road for it to get to that speed, the track they tested the veyron supersport on, had a shorter straight then the road the Areo was tested on.
Pinkishbass91 1 year ago
@Pinkishbass91 He means production car. Viprer ACR is the fastest production car on the nurburgring. Those other cars are like super-special, not every customer can buy one. Not sure if the 2012 GTR, ZR-1, or new 911 turbo has beat it's time yet, but the fact still remains. Every great car can be eclipsed by an american car. If you don't admit that, you're biased. I am a tuner, and an import guy, but for you to not think american cars are just as good/better, is fawked.

@Pinkishbass91 Actually, I said A FULL lap around the ring. The cars you mentioned did the short lap, while the time difference between the short lap and the full lap would not make up for the difference it would be close. not to mention they are all built on purpose built track cars not road cars turned into track cars.
MrAngryRedneck 1 year ago
@Pinkishbass91 As for the Aero, They would not allow the Aero on the track because it is VW groups private track and it was certainly not in their intrest. Not that it would need it since it did it with an amature driver with no racing exp. on a 4 mile stretch of rough paved public road 4 miles long with a dog leg bend in the middle which he had to navigate at speeds around 210mph. unlike the test track for the veyron ss which has a straight of 5.6 miles
MrAngryRedneck 1 year ago
@Pinkishbass91 If thats not enough, wait till the end of this year when the next generation Aero starts shipping out with 1350hp and a reported top speed of 275mph (plus a MUCH more refined look than the current generation) google "2012 SSC Ultimate Aero II" you find There is an excellent artical on topspeed,com I'd put up a link but you know how youtube is all gay about that. While the top speed is yet to be officially recorded it was built to beat the ss so let the rivalry begin!

@SypherDubstep Also if you think about, in a rotary, there are more ignitions per revolution of the eccentric shaft, and there are more revolutions per minute as rotary's rev higher. Apposed to the piston engine which does one ignition every 2 revolutions (4 strokes) of the crank shaft and isn't rotating as much.
Pinkishbass91 1 year ago
@SypherDubstep This is not the one used in the RX8 of course, the RX8 only has 2 rotors.
And it is less efficient as it does not burn all the fuel and air mixture, as in a Piston Engine. The RX8 was designed (I'm not exactly sure how) to meet the emissions standards and be more efficient then the previous series 8 RX7 as well as be a lot safer. Thus making it slightly slower I'd imagine.

think like this: in each rotor you have 3 face for combustion, its like having 3 pistons in the same cilinder, if you multiply by 4 (the # of rotors) you''l get the equivilant of a v12 in the same space as inline 4 cilinder engine! i call that OWNAGE! add the same turbo harge used in v12 and you'll get PWNAGE!! all that in could fit in 2hp citroen or on a big bike!! very dangerous technology if you ask me!

@bazengao Multiply by 3, but divide by 2 (IIRC) due to the eccentric shaft rotation, which gives the equivalent of a 6 cyl for a 2 rotor.
eddie8080 1 year ago
@eddie8080 divide? there nothing to divide! eccentric shaft? it doesnt matter you have 3 combustion faces in each rotor! the eccentric shaft doesn't influence it anything... you still have 3 combustion faces for each rotor! and this a 4 rotor! therefore 3x4=12combustion faces=12cilinders=V12 now tell me where does the eccentric shaft enter in this function??
bazengao 1 year ago
@bazengao Disregard my last, was thinking of 13B.
eddie8080 1 year ago
@bazengao The eccentric shaft (equivalent to a crankshaft) enters into this because it turns at 3 times to the rotor's 1. So at 3000 eccentric shaft RPMs the rotors only turn 1000RPM.
Also, the 2.6L 4 rotor is = to a 5.2L V8. With 4 rotors you get 4 combustions per revolution of the eccentric shaft displacing 2.6L. This is directly comparable to a 5.2L V8 that also has 4 combustions per revolution of the crankshaft displacing 2.6L. Remember 4 stroke piston engines only fire every other rev.

@Warblade118 so does that mean a 1.3 renesis is equil to a 2.6? I had an 04 rx8 and it was gutless, what are these engines outter dimensions similar to? a 4 cylinder?
firechicken76 1 year ago
@firechicken76 For a comparison of displacement most racing body's view the rotary as double its "rated" displacement when comparing it to a piston engine. So yes, a 1.3L 2 rotary is = to a 2.6L 4cly piston engine in both displacement used in combustion per revolution of the crankshaft (or e-shaft) and number of power strokes (impulses) per revolution of the crank or e-shaft. The 13B in the RX7 weights about 250lbs, is a little shorter but a bit wider than a 4cly. I'm not sure about the RX8.
Warblade118 1 year ago
@Warblade118 13b renesis i think is the same basic size as the older 13b, it's just aluminum instead of iron. I hate how everyone says " its only a 1.3 and has 238hp"
firechicken76 1 year ago
@firechicken76 Yeah, it's very misleading isn't it? I looked into it a bit more and found the renesis does weigh about 250lbs (dry) so in reality its not much lighter than a typical 4 cly engine, its outer dimensions are just a little smaller. But when you think of is as = to a 2.6L 4cly its 238HP makes alot more sense. And is only about 91HP/L which pretty unremarkable compared to alot of modern 4cyls.
