RX-7 Question

[2of9]

ok, i wuz passin thro my March 2003 issue of SCC (sport compact car) and it said the RX-7 had a "claimd torque" of 758 hp @ 9500 RPM!!!!!! can the RX-7 hit 9000 rpm?! well jus askin cuz 758 HP @ 9500 RPM is ALOT!!

Are you talkin power or torque, cuz you quoted torque but gave a value in HP.

The third gen RX-7 had a redline of 8000 rpm, and 255 or 265 hp (depending on US or Japanese model), with 220 or 222 lb-ft of torque.

That car your talkin about has some serious mods on it to get 700+hp, that would make it capable of 9500 rpm

no, this was on "how to buy a used" STOCK 1993 RX-7s. if u dont believe me, get the March 2003 issue of SCC.

Naw, man they don't hit nine grand stock.

But, when you hook up any engine, you balance and strengthen it better, which means its more capable of going into the high RPM band...so guess what the tuners do? They tune it to go into higher RPMs! Heh. Also that, since extra aggressive cams(in normal engines), and big turbos, you have to wait till the high RPM band to see the REAL power, so the super tuners make ultra agressive changes that make power in the high RPM band, so to get all they can, they change the car's computers make the fuel cutoff higher up.

Whatever, my third gen saw 9000 RPM quite a few times.

You can modify a stock engine to rev freely to 12-13K RPM.

If you modify it, it isn't a stock engine. A stock rotary (especially a 13B) will not rev to 9k. A modified one will.

My ported 12A in my autocross RX3 made peak hp at 9250 rpm. It also ran out of breath just about there. The IMSA RS RX3 I crewed for had a modded bridgeport (into the water jacket) and it saw 12k. But it was hardly streetable with ports like that. Joe Varde's IMSA RX3, and the IMSA Akai RX7 could twist to 14k, but they didn't live more than a few hours like that. The Mazdas that won the 24 hour races never went past 10k.

To reiterate. A stock rotary won't turn 9K. A modified one can. A modified rotary can hit 12-14k, but they won't live long doing so, and won't be streetable.
