Rx7s have no torque?

While at the local tuning shop, the guys were telling me how we have no torque at all off the line.

Is this true? I always thought they had a lot of torque, but thats just me. (maybe it call comes after 3800 rpm?)

Yeah, what Mark said. To some Honda's? I would say we would have more torque than other models. To a V8? No contest.

I think its a well known fact that were a higher rpm power.

who needs torque when you can spin the engine 10k times a minute? (renesis at least... 245 hp, 159 torques)

dunno about a lack of torque, depends what you compare to, what rotors do seem to have is a 'torque hole' below about 1500rpm.

they don't have a huge torque peak that snaps back your head, but the torque grows more and more with the rpm (well, at least that's what it feels like).

Ive never understood the fan boy ravings about having 1500rpm peak torque. Press on the gas pedal and the clutch, then let the clutch out. WOWOWOWOW@!@#!

good torque everywhere is a nice thing for a road car... hardly necessary, but certainly nice.

Honestly. When most people talk about torque, they are referring to it in a race environment. How much time do you spend below 4k at the drag strip? Or below 6k at a road course? Or below 5k at an autocross?

Lets not forget our cars weigh anywhere from 2600-2800lbs so it doesn't need a whole lot of torque compared to a 3500-3600lb Supra or something. Plus the smooth power delivery of our rotaries too...

well, the guy who said it runs an S13 and an S14 at the moment, and one of the guys agreeing with him had an Accord..

i just found it kinda funny, because i always thought a rotary had massive torque for how small the engine was.

While rotaries do not have a lot of low end torque or a lot of peak torque, they do a have a very flat torque curve.

This means most of what 'little' torque we have gets used over much of the rpm range.

my roomates stock S13 has some awesome low end torque very fun to drive but when you go sliding through a corner it's much harder to control. my 7 has much smoother power delivery and does more of a gradual slide compared to his S13's instant sideways.

Its good not to have too much torque cuz it can get out of control really easily. Rx7's seem to have the perfect balance. Although for people that are used to torque it can seem rather little. Truth is If you know how to drive them Rx7' s are great off the line, especially the turbos, and also FD's. FD's have excellent control off the line, and when you mod them they can beat most if not all cars off the line. From what ive seen and heard the only cars that can beat them fairly eaisly are AWD systems like on the Skylines, WRX and such

one eyed rotary folk crack me up... "good not to have too much torque"
bwhahahahahahaha. What do you think going to a free flowing exhaust, huge turbo and high boost does?

Like EvilRotor said, the torque is spread over the rpm span in a flat manner, so it's always near the max number. The hp curve is a very steep climb to the top. Both very similar in relation to a Honda S2000.

The turbo makes up a lot in the torque department.

compared to a 3500-3600lb Supra or somthing
They are such fat pigs, the first gear in a Supra is a stinking stump puller, although it must take alot to get all that girth moving.

if you were to look at a dyno test of a non modified rotory engine you would find that there is NO fall off. the higher the rpm the more hp and torque you have (as long as the fuel system will handle it). my stock 13B (only rev limiter removed) keeps increasing power even at 11K. the slope may not be as steep but keeps creating power. (have not intentionally revved over 11k, don't want to hurt the engine more than that....lol)

Thats funny i did not think you could remove the rev limiter with out getting a replacement ecu. And also the 13b has vibration and flex problems past 8800 rpm so how did you keep it from blowing up? The stock injectors would need to be at 110 duty cycles *not possible* to keep a engine from leaning out that high. My last question is what the hell are you smoking, that must be some good stuff.

um....wow.. a stock fc revving to 11k...thts interesting if not imfrigginposible. and yes nilla you have to get a new ecu to remove the rev limiter....are you shure you arnt thinking 1100 rpm?
