Miss my old Rx7 which was destroyed in an accident! It looked exactly like this one! It sucks they stopped producing the Rx7 though. Would definitely own one!
what kind of rpm do these turn ? my buddys got a build 20b sitting in his garage it came out of a tough truck and i was thinkin about buildin a mazda but i was just wondering what kinda rpm they turn cause they screammmmm
Question. I have done a 13b turbo motor swap with a tune ecu. My car runs but when it begins to boost, the car loses power and begins to sputter. What should b done?
@jswoozie it could also be the point that the secondary injectors are kicking on and that is a pretty hard point to tune perfectly for. i think every rx7 i know has that hesitation for a split second but you can get it practically tuned out with a really good tune
just call it housing, but while i was working in halliburton as a co-op, i was talking to my boss who specialize in surfaces and used to work for southwest research institute and worked on the rx8's engine. It seems they really can't do much more for the engine in coating and design without skyrocketing the cost. heavier housing will negate the weight to power advantage of the rotary =(
@botchla90393 I'm pretty sure the 20B would be a decent bit heavier than a 13B, it's essentially 50% more engine, the extra Rotor and housing, an extra center plate and longer e-shaft, plus all the other kit needed, injectors, coils and such. That said you can get a lot more power from a 20B, and more reliably too. The only annoyance with a 20B over the 13B for me would be mounting it far enough back to keep the weight balance in the car, especially for track work.
@Pezzletism lol you realize the only difference between the 20b and a 13b is 1 exta rotor and its housings, right? its not a lot more weight, and it signifigantly increases power. its definitely worth it.
i love both engines too but the rotary has won many great races like lemans so it has proven itself multiple times and v8s are kinda of a "standard" they have been here from the beginning. and there weights might be close but center of gravity might be another thing to look at. i like the rotary because its different
This is definately not true, you can smoke alot but not any, there are 9L's V8's produce over 100hp NA.F1 V8's are 2.5L and produce 800hp NA and will also rev higher. Yes its a F1 but its also a NA V8. definately can't say this will smoke any NA v8. Even a properly tuned 4.5L v8 can take this on, Nissans VK45DE engine used for the Nissan GTR in the Super GT-GT500 easily produces 600hp NA without restrictions,+ v8s have way more torque. Not trying to say rotors are bad just v8's are good too.
yeah i get wat u r trying to say . but if this machine is fully 'TUNED' , then it realli will smoke any NA V8 . im serious . there is a limit wat a NA V8 can do . cheerz .
The largest rotary is 2.6L and the max hp it produced was 700hp NA, but never raced at that due to reliability issues, and just for arguement sakes an F1 engine for current standards produce about 800hp wit ha 18k rpm limit, some of these engines can rev out to 28k rpm thats from a 2.5L NA v8, so even if you pull the displacement arguement the v8 still wins. Theres a reason why piston engines are so popular. so lots of other larger displacement NA v8's would take on this easily.
+ if you take that the 26B was tuned by professional racing team with a huge budget, and only made 700hp max then a 20B which is about 77% of the 26B in displacement would produce about 539hp max in quick theory and power estimate, now many NA v8's would EASILY produce that, with more torque to the wheels. as for v8 track engines nissans VK45DE, Toyota's 3UZ-FE, pretty much half the European performance v8's , GM's LS series engines will all easily produce 600hp.
That was just an quick estimate but i'm sure its not too far off, find me some NA 20B's pp or not over 600hp, if you do I'm sorry for my bad estimation. don't really look at much NA rotarys
ow i forgot to tell u weights play a part too u noe . rotary weighs lesser than any of ur V8 . plus RX7s are light , compared to ur V8 cars . even if u put a stupid V8 inside the good 7 , it will not b too ideal . tats if u noe wat i mean . give u a hint , engine weighs heavy on the front of the car ? nah nah nah . V8 on a 7 is juz not 'BALANCE' !!!!! no point arguing wif u . have a good day MATE
an LS1 is only 60lb more than a 13B-REW, easily counter weighted, with a dry sump, battery, fuel mm system etc all at the rear, and some minor weights if needed, thats why its such a popular swap. Balance stays in tact, while having alot more torque.
yeah too much torque tat made u go dancing in the corners or probably understeer so bad when u corner . sorri not a fanboy of a useless v8 . save it for urself . v8 r like a bodybuilder . no skill no real strength juz look strong . but empty on the inside .
thats gota be the most dumbest statement ever, its called car control, not a fanboy just plain facts, you think all the professional racing teams using v8's are wrong? how many do u see using rotarys not many? you think consistent wins are wrong? you think F1 cars arn't the fastest track cars? these numbers all prove that v8's are highly competitive, your just too ignorant to know that, cause ur the rotary fan boy. I have respect for rotarys there great engines, v8's are just better.
nice arguement :D lol, lots of reasoning i see there? I'm ignorant cause i can prove why v8's are proven better performers?, not bragging, just stating truth backed by numbers, backed by professional wins. very nice arguement u got there ...
g'day mate, are you sure that LS1 is only 60 pounds heavier than 13B ? yagam is retarded. like u said, both great engines. he probably drives his mums corolla
yup i'm quite sure, remember the LS1 is all aluminum, and the 13B-rew is cast iron + 2 trubo's. It'll be on the net somewhere just have a look on google.
im scared of owning an all aluminum ls1...if it overheats too long heads warp...all it takes is one thermostat and warped heads....id perfer iron block and heads...or if u got money to throw away go all out with titanium block and heads...
If you want the best track performance then you definitely have to go aluminum block, there not designed to have ridiculous high hp, 700hp max, the block will stay in tack. I don't think they make titanium blocks. Anything above that then go iron block. which when you turn to iron block your car won't be used for track racing anymore .. just straight lines. and plus a iron block in a rx7 will off set it even more.
really??? i do apologize, let me rephrase my comment to a conversation you were not a part of.
to manufacture a 13b housing out of titanium would cost more then a house! now since some of us actually work, as a cnc machinist, when we come home after a long day maybe our heads are a little fried and we really don't give a fuck about the correct part names of components since we have been dealing with that shit all day,
ive rebuilt an engine, and tore down many, the side housings are usualy not the problems. Finding a good rotor housing (2 and 4) is the hard part. they should make the housings out of high nickle cast iorn. it would make the engine heavier, but help in its longjevity.
They have to have a rev lim. Normally it's around 9k. If they didn't have it on it could go higher. Due to rotars don't exactly have anything stopping them from spinning they need it :P. i may be wrong. but this makes the most sense to me.
piston engines will keep reving also if they don't have limits, they'll rev till they can't rev any higher (naturally) or till they blow up, same with rotaries.
i guess you can call 300hp all good. but that is a 15,000 dollar engine swap. which to me is a waste if all this dude got was 300hp. if he went the turbo routhe with is money. he could easily made 7-800hp to the wheels for about 8,000 on a 13b motor
and the drboyton was putting it in a way that bridgeports can't rev past 8500-9000 wtf hes got know idea tell him and who ever thinks they know about rotors to do there reash and shut the fuk up
Unlike the conventional 4 cycle engines we use today that peak and then lose power quickly. A rotary engine keeps producing more horse power as it revs higher. Is this true?
i was just saying that it was reving much high than that and that a brdgeport can rev way more than 8500-9000 so i was saying that my m8s revs way more than 9000
they are waiting on report so they can start producing and selling the turbo for other rotaries now the car has been set on basic tune so he can't get past 4 grand lol the funny thing is the it idles on 2250 rpm so he never drives it plus it way too loud the engine builder reckons it will easy pull close to 600kw if not more at max boost on 30 psi it will eat that 20b n e day
drboyton u have no idea my m8 just got his series 5 back from mazprep in aus its a 13b full cut bridgeport he spent about 50k on the engine and it revs to 15000 rpm its one tuff rx7 it took 1 1/2 years to build at 9 psi it made just over 350kw and that wasn't at full pelt no one has seen it except a few people it has a prototype turbo from garret turbos and
but on the other end, if the gears are too tall for the engine, the engine will not beable to pass a preticular rpm due to the gearing. gearing is no the only part to top speed resistance, it also includes drag coeficents and roling resistance of the vehical.
and on another note, for example; a s4 rxt turbo; this too has low rear end gears (4:10) but with a high OD manual tranny (top ratio of around .761 over). this means at the drive shaft turns 1 full time per aprox every 75% of a total engine rotation, but then is reduced by it taking 4 an 1/10ths rotation of the drive shaft to rotate the axle one full time.
This comment has received too many negative votesshow
20 b cock its a 13 b asshole u wish u had a 3 rotor engine in there...hey plp its a 2 rotor 13b engine not a 20b 3 rotor engine this cock sucker is runing...aaa who gives a shit anyway the shit video and car....
you're an idiot. apparently gave a shit enough to watch this video and comment on it. and it is a 20b. check again. look at the 3 air filters you moron.
the reality is that neither V-8's nor rotary engines are very ethical they waste to much gas for the power they have. Rotary engines are still to underdeveloped but I'd rather have a rotary engine blow on me then a V-8 anyday their an easy rebuild and with a V-8 most of the time a blown engine always means get a new engine
in my comment i spoke about the 1/4 mile, true, i never said that around a track a muscle car would be quicker, but in ur previous comment u said how a rx 7 would beat a muscle car n top speed???!!! and i judt dont see it ever appening
This comment has received too many negative votesshow
wat idiots u have no idea, have u ever driven a rx7, or a muscle car, i wouldnt think u have, stock muscle vs stock rx7, muscle car wins, easy, so shut up, dont get rude bcos u aint got a clue, fucking cunts
your stating the obvious u idiot, everybody on this comment page knows rx7's and cars alike are lighter and they handle better, but u being your nieve self dont relise, the power out put of a muscle car V8 is greater than that of a rotary, listen u idiot, i have driven chargers, mustangs, camaros, buick specials, challengers, cuda's the lot and most imports, becuase alot of my frends drive imports and ill say it clearly for you, stock muscle cars are faster top end that imports. idiot
of course top end is faster for a muscle car. Being a hulking piece of solid steel they would not get to 60mph as quick as an 13b turbo. but would beat it in top end speed.
Yes a v8 will go faster then a 13b once you get into top speed but tell me how many people actually make it to top speed in a 1/4 mile.. unless they are geared making it a non stock car.. there arent that many race tracks that have a 5km long straights or more..
but that is my point which clearly stated many comments ago, a stock muscle would go faster (top end) than and import like a rx-7. im not stupid i no round corners rx-7s are quality, hence the reason why there such favoured drift cars but stil muscle cars in every other way are better, and im talking about stock motors, high torque output, bigger discplacement, bore, stroke, higher bhp etc i would have a muscle over a import any day of the week
almost anycar can go faster then any other theroreticaly, its all in the gearing and engine power. lets say for example, a 60s or 70s muscle car with the factory preformance package; usualy a non-OD tranny (4spd manuals and 3spd autos) and low rear end gears for rapid acceliration, how ever this severly limits the top speed. the engine will not beable to turn fast enough to make a "good" top speed due to the drastic rear end reduction gear.
so basically nilo4ever, ur saying that an approx 7litre v8 of a mustang, charger, challenger etc. would be quicker than a 2litre rotary engine of an rx-7, dont get me rong rotarys are good engines, but there is no way on this earth that a stock rx-7 would beat a muscle car, even if both cars were maxed out the mucle car would still win, maybe not on corners, but in a drag a muscle car would leave an rx7, think about it, more cylinders, bigger displacement, more horsepower, higher torque.
I wasn´t talking about compairing stock cars. Yes, stock the muscle would beat an rx7. What i´m talking about is potential, not just on a quarter mile. My point was that you can´t say muscle is faster ALLWAYS. All depends on the circumstances. Just because muscle is faster in a 1/4 mile you can´t say it´s faster period. Take it out on a track and start hitting those corners, then it will suck ASS. Read the post that spartan1893 posted. That´s my point.
i stated in my point that it wouldnt win in corners, so what are u on about, im on about top speed, not round a track, and im not saying its faster period, im on about top end
Are you guys retarded?? Muscle is faster?? When? Where? On track ( not just straight )rx7 would kick any muscle ass. Muscle cars can barely clear a corner. Maybe in quarter mile muscle is faster but absolutely not top speed! No muscle i know can barely clear the 200mph mark. No problem for an RX7. The fastest RX7 on the quarter mile does 6sec. Not slow according to me. Muscle has way more torgue yes, but you can´t put all RX7´s in a corner and say Muscle is faster. Depends what kind of speed.
u cant say neither is faster cause to compare it has to be fair....nothing is better u gota compare engine life weight pistons, what the car was made to do (straight line, track0 rules regulations etc etc lol if it was made for top speed accerleration how much muny was put into it, how old it is, how much it cost from dealer .........no 2 cars can really be compared
RX-7's have to be one of the best sounding tuners out there.... even tho they r my fav car, i still think muscle cars got way better engine sound.... nothin beats a V8!!!!! (but this comes extremely close)
the best sounds of a car are raspy cammy exhaust notes, e.g RX7 (wankle rotary) Civic (Very Cammy and Raspy Because Of V-Tec) Accord (Same As Civic) And My Brothers Proton Lmao Sounds Lame, Goes Well And Sounds Nice!
The best sound is a horizontitally opposed, air cooled, 6 cyl. turbo!! My Porsche 930, balls out, is God's symphony!! My RX-7 is a friggin blast to drive, but never cared for the burpy sound of the rotary.
does anyone know hoe fuel efficent these engines are???

lol 7-800hp atw for 8k? thats over 1000hp at the flywheel! are you kidding me?
botchla90393 3 years ago
ah shit i accidentally removed your comment, but yeah sounds about right in Aus dollars.
botchla90393 3 years ago
i guess you can call 300hp all good. but that is a 15,000 dollar engine swap. which to me is a waste if all this dude got was 300hp. if he went the turbo routhe with is money. he could easily made 7-800hp to the wheels for about 8,000 on a 13b motor
delasoul17 3 years ago
you can buy tri rotors that make 7-800whp for like 8k

300hp @ 8500 rpm.

Wow 300 to the wheels all motor is pretty good.

ok really and that was full throttle
mrskitz 3 years ago
and the drboyton was putting it in a way that bridgeports can't rev past 8500-9000 wtf hes got know idea tell him and who ever thinks they know about rotors to do there reash and shut the fuk up
mrskitz 3 years ago
well yeah bridgeports can rev higher than 8500-9000...but in THIS video he only revs it to 8500 i have proof if you dont believe me.
botchla90393 3 years ago
But do you lose power after it hits its peek RPMs?
lets say 7800( just a number)
SNIPINGBEAVER 3 years ago
well yeah on this car it probably makes peak power around this rev range so revving over its peak yeah the power would slowly drop off...
botchla90393 3 years ago
do they have a way to keep power at 8500+ RPM's
SNIPINGBEAVER 3 years ago
Unlike the conventional 4 cycle engines we use today that peak and then lose power quickly. A rotary engine keeps producing more horse power as it revs higher. Is this true?
mattkeeler 3 years ago
i was just saying that it was reving much high than that and that a brdgeport can rev way more than 8500-9000 so i was saying that my m8s revs way more than 9000
mrskitz 3 years ago
they are waiting on report so they can start producing and selling the turbo for other rotaries now the car has been set on basic tune so he can't get past 4 grand lol the funny thing is the it idles on 2250 rpm so he never drives it plus it way too loud the engine builder reckons it will easy pull close to 600kw if not more at max boost on 30 psi it will eat that 20b n e day
mrskitz 3 years ago
what the fuck does that have to do with the car revving to 8500-9000 rpm (which is correct).
botchla90393 3 years ago
drboyton u have no idea my m8 just got his series 5 back from mazprep in aus its a 13b full cut bridgeport he spent about 50k on the engine and it revs to 15000 rpm its one tuff rx7 it took 1 1/2 years to build at 9 psi it made just over 350kw and that wasn't at full pelt no one has seen it except a few people it has a prototype turbo from garret turbos and

top speed is all about gear ratios
but on the other end, if the gears are too tall for the engine, the engine will not beable to pass a preticular rpm due to the gearing. gearing is no the only part to top speed resistance, it also includes drag coeficents and roling resistance of the vehical.
theblackmech 3 years ago
and on another note, for example; a s4 rxt turbo; this too has low rear end gears (4:10) but with a high OD manual tranny (top ratio of around .761 over). this means at the drive shaft turns 1 full time per aprox every 75% of a total engine rotation, but then is reduced by it taking 4 an 1/10ths rotation of the drive shaft to rotate the axle one full time.

te37drift 3 years ago
the reality is that neither V-8's nor rotary engines are very ethical they waste to much gas for the power they have. Rotary engines are still to underdeveloped but I'd rather have a rotary engine blow on me then a V-8 anyday their an easy rebuild and with a V-8 most of the time a blown engine always means get a new engine

catchmeifucan91 3 years ago
an rx7 would easly beat a muscle car in top speed.....
duhhh
thats like fucking commen sense
JaHarrison01 3 years ago
haha well of course it would depend on what rx7 vs what muscle car....
and typically it would be more likely for a v8 or muscle car to have a higher top speed than a lightweight 4 or rotary...

wat idiots u have no idea, have u ever driven a rx7, or a muscle car, i wouldnt think u have, stock muscle vs stock rx7, muscle car wins, easy, so shut up, dont get rude bcos u aint got a clue, fucking cunts
catchmeifucan91 3 years ago
rofl u fag rx-7 beat wank muscle cars easy they handle better are heaps lighter ive driven both.. 6ltr v8s and 13b's rotors go harder
macneil29 3 years ago
your stating the obvious u idiot, everybody on this comment page knows rx7's and cars alike are lighter and they handle better, but u being your nieve self dont relise, the power out put of a muscle car V8 is greater than that of a rotary, listen u idiot, i have driven chargers, mustangs, camaros, buick specials, challengers, cuda's the lot and most imports, becuase alot of my frends drive imports and ill say it clearly for you, stock muscle cars are faster top end that imports. idiot
catchmeifucan91 3 years ago
who gives a fuck? this rx7 is fucking nice and thats all that matters.
botchla90393 3 years ago
i give a fuck when people dont no wat there talking about and there trying to get rude
catchmeifucan91 3 years ago
of course top end is faster for a muscle car. Being a hulking piece of solid steel they would not get to 60mph as quick as an 13b turbo. but would beat it in top end speed.
Mountainman19 3 years ago
Yes a v8 will go faster then a 13b once you get into top speed but tell me how many people actually make it to top speed in a 1/4 mile.. unless they are geared making it a non stock car.. there arent that many race tracks that have a 5km long straights or more..
macneil29 3 years ago
but that is my point which clearly stated many comments ago, a stock muscle would go faster (top end) than and import like a rx-7. im not stupid i no round corners rx-7s are quality, hence the reason why there such favoured drift cars but stil muscle cars in every other way are better, and im talking about stock motors, high torque output, bigger discplacement, bore, stroke, higher bhp etc i would have a muscle over a import any day of the week
catchmeifucan91 3 years ago
almost anycar can go faster then any other theroreticaly, its all in the gearing and engine power. lets say for example, a 60s or 70s muscle car with the factory preformance package; usualy a non-OD tranny (4spd manuals and 3spd autos) and low rear end gears for rapid acceliration, how ever this severly limits the top speed. the engine will not beable to turn fast enough to make a "good" top speed due to the drastic rear end reduction gear.

spartan1893 3 years ago
so basically nilo4ever, ur saying that an approx 7litre v8 of a mustang, charger, challenger etc. would be quicker than a 2litre rotary engine of an rx-7, dont get me rong rotarys are good engines, but there is no way on this earth that a stock rx-7 would beat a muscle car, even if both cars were maxed out the mucle car would still win, maybe not on corners, but in a drag a muscle car would leave an rx7, think about it, more cylinders, bigger displacement, more horsepower, higher torque.
catchmeifucan91 3 years ago
I wasn´t talking about compairing stock cars. Yes, stock the muscle would beat an rx7. What i´m talking about is potential, not just on a quarter mile. My point was that you can´t say muscle is faster ALLWAYS. All depends on the circumstances. Just because muscle is faster in a 1/4 mile you can´t say it´s faster period. Take it out on a track and start hitting those corners, then it will suck ASS. Read the post that spartan1893 posted. That´s my point.
nilo4ever 3 years ago 5
o looks like we r on da same side hehe lol jks now i undertsand true what u say ....only the person writing knows what they mean
spartan1893 3 years ago
i stated in my point that it wouldnt win in corners, so what are u on about, im on about top speed, not round a track, and im not saying its faster period, im on about top end
catchmeifucan91 3 years ago
Are you guys retarded?? Muscle is faster?? When? Where? On track ( not just straight )rx7 would kick any muscle ass. Muscle cars can barely clear a corner. Maybe in quarter mile muscle is faster but absolutely not top speed! No muscle i know can barely clear the 200mph mark. No problem for an RX7. The fastest RX7 on the quarter mile does 6sec. Not slow according to me. Muscle has way more torgue yes, but you can´t put all RX7´s in a corner and say Muscle is faster. Depends what kind of speed.
nilo4ever 3 years ago 5
u cant say neither is faster cause to compare it has to be fair....nothing is better u gota compare engine life weight pistons, what the car was made to do (straight line, track0 rules regulations etc etc lol if it was made for top speed accerleration how much muny was put into it, how old it is, how much it cost from dealer .........no 2 cars can really be compared
