How many RPM can a stock 1984 rx-7 do, like what is the redline?
Some guy on a tuner show said that he takes off at the line with 13,000 revs.
Can I do that?
I am in the process of buying an '84 rx-7

that's the 10A, right?? er, well, maybe you wouldn't know...

anyhoo, i thought the redline was something like 7.5k or 8k... certainly not 13k... for that, you need a big, fat, expensive race rebuild, with shaved lighter race rotors, a stonger e-shaft would help, and you'd definitely want (at least) new bearings, seals, refinished housings... 13k takes a LOT of work to attain, it won't do that as you buy it, no.

btw, you should go to www.rx7club.com for this kinda thing... there are more 1st gen owners there.

an 84 G, GS, or GSL, as stock, is the 12A(carb); a GSL-SE is the 13B(Fuel Inj). Same for 1985. As I recall the redline was 7K; it'll do more - but I'd suggest not doing more than 1K more than the redline (if it's really 8K, no more than 9K). Unless you have it rebuilt per above.

Yes it is a 13B, and the racer that was interviewed was a guy in the all motor class on the NHRA. he had a bright yellow 1st gen.
he sadi that he left the line at 13 big. which means that he goes higher than that!
To be able to rev that high would be so sweet.

In a drag racing application the start revs are usually higher than the revs at which you shift.

We run a Datsun 1200 Coupe over here with a 13B Turbo engine that has run 8.4@156mph, and we usually leave the line at about 11,000rpm. BUT, this is only so that the car leaves the line as quick as possible. With a huge turbo you need to rev the engine very hard so it doesn't bog down off the line becasue it produces almost no boost when free revving the engine.

Gearshifts are made at around 9,000-9,500rpm as this is just over peak power.

If the engine makes peak power at 7,000rpm and tapers off from there, why rev it out to more than 8,000rpm? Plain stupidity.
