Just recently i went up against a brand new evo modified to the teeth. The thing that made me angree was not that he beat me but the fact that i couldn't get or keep any traction, so i stayed at the light burning my tires right off while this guy goes flying away.

So that being said i was thinking i've never seen any one change a rx-7 into a all wheel drive car.

I know that its an expensive thing too do and it would take quiet a bit of work but i'm planing on doing this and i just wanted to get peoples input on it wether good or bad.Or maybe you've done this yourself let me know what you think personally so i have something to go off of.

 

$100,000 and several years?

what where you racing? And why did you burn the tires? why didn't you slip the clutch? More info needed. Also you need to remember that the rx-7 was not built to be a light to light drag racer. It was designed to be light weight and handle great thru the corners.

 

I think that an AWD RX7 would be horrible. I much prefer the RWD and plus on the highway from a roll u will own AWD cars....they have to distirbute power to all 4 wheels while you only distribute power to 2.

 

neither was the Evo.
you can get traction. you dont need awd for a car to hook up.

 

I cant find the link but there is a video of a 7, Skyline, Wrx racing through this 2 minute course and the 7 is the only thing that looks like it has control of the road... if anybody can find that post its a great vid!

 

Also the rotary has no torque, with the extra 300-400 lbs load on ur engine. U car wouldn't stand a chance in any style of racing. The reason the rotory works in the 7's is that the car is soo light that it doesn't require much torque, and makes the most of it's horespower.

 

rotaries make torque. 2nd gens are fairly light, but they're not feathers. i think rotaries have proven themselves in all styles of racing; from open-wheel to rally, drag to drift. and torque isn't everything. also, torque curves come into play. some v8s, for example, make they're max torque around or before, what, 2000rpm? i believe an engines highest efficiency is at its max torque; if true, this is probably why V8s can get good gas mileage, but eat through gas at wide open throttle. some rotaries torque curves continue to build throughout the rpm. then there's also porting style and turbo vs non-turbo.

 

Very much true Casio....Rotaries have kicked *** in all styles of Racing...and will continue to cease and amaze all competition...

 

i also forgot about the Cosmo. yes, many think "20B" when they hear Cosmo, but 20B is still a rotary. i'm not quite sure what Cosmos weigh, though. i imagine they tip the scales at over 3000 (american) pounds. also, the older cosmos were turbo 13Bs.

would i want a rotary in a stock body F-Body? probably not. i'm not sure how those 3600lb (i think) pigs are geared, though. it'd be interesting to see a 500hp 2 rotor go up against a 500hp 350; gears the same and all. maybe its just me who is curious about crap like that.

 

An awd rx7 would be horrible. take out the rotary and put it in a 626 awd, that'd be nice and somewhat affordable. Don't feel bad about getting beat by a evo, I got spanked by a 03' mustang gt, *clutch is gone*

 

id put my money on the 7
its lightrer and handles better
just my $.02

 

minus the cost, what would be so bad about it? i know its been done. i saw a rally 2nd gen once that said it was awd. i wouldnt mind an awd rotary platform. i dont see what would be wrong with it.

EDiddy - i meant the same max power from a rotary and 350 in a car keeping the stock drivetrain (tranny back).
ie. 400hp (turbo) rotary in an f-body vs 400hp (n/a) 350 in an f-body; same gearing.

 

Ok so rotories have torque.... at 6k rpm, which mean if the car were 4WD it wouldn't dive under 5k or so, so it's would blow through clutches like nothing. Even RWD 7's suck for power under 3k rpm, but that's also y 7's kick *** b/c the redline is so high leaving the power band so large.
with that $100k U have to invest in AWD u'd better be puttign in a 20B, otherwise it'll be like a bronco with a 4banger.

 

interesting. though turbos seem to make awesome torque, lets look at this N/A dyno. look how flat its torque curve is. i wish i had access to plenty of dyno sheets to see the torque numbers at 1500-3000rpm to compare stock and modded engines.

also, i see that the graph starts near 4000rpm, but the torque curve itself is flat. the low end horsepower sucks, though.

 

Rod Millen created a awd rx7 and used it to rally race........

everybody knows who he is.......he woulnd have done it and spent the money developing it into a reliable rally car,if he didnt see the benifit. and thats saying alot cause you all know the life of a rally car......

 

It's how wide a powerband is that matters, not torque. Read the first 3 pages: https://www.rx7club.com/general-rotary-tech-support-11/horsepower-vs-torque-67630/
