Stock HP?

[Onslaught]

Hey guys.. I don't actually own an RX, my friend does and I help her out with it all the time, we joke constantly about racing our cars (I own an 87 Supra) I was wondering what a stock 86 RX7 puts out for horsepower? figured this would be the place to ask

[AusTexRex]

86-88 NA = 146 HP @ 6500 RPM w/ 138 Ft/lb @ 3500 RPM
86-88 Turbo = 182 @ 6500 RPM w/ 183 Ft/lb @ 3500 RPM

Thanks

Hey, I'm pretty new to this forum and I didn't want to add a new thread just for this but it the best time to shift to the next gear at your peak horsepower moment?

I mean, here someone said peak horsepower is at 6.5k, so is that the best time to shift? Someone give me some insight because that's where I always used to shift my Mirage.

Anybody feel like answering my question?

If you look at your rpm with gear ratio...that answer will come to you.

OK, I normally shift by ear, which is usually 5.5K to 6K. But, when I'm doing something STUPID I shift at 7K+.

If your FC can handle that or not depends on what you have done as to performance mod.

[Canaduh]

I hear about people shifting at 7k+ all the time, personally i have never done it, but i heard it isn't that bad to a lightly modded rx7.


.....I take no responsibility of damage or accident. :P

[black rocket]

...but if you do make sure drivetrain is secured. Otherwise tweek by torque will do unwanted damages.

What would an 83' with a 5 speed put out? Does anyone make a turbo for it?


(i know this is the 2nd generation forum part)
