Rev limiters?

Cory Simpson · 03-08-05, 03:21 PM

Well I've hit red line a couple of times, and made the buzzer in the car go off once

And the thought of warping stationary gears doesn't do anything for me.... So I'm looking for a rev limiter, but one kind inparticular. I think it is a dual stage? I've heard one FD with it, and it was awsome. He reved it, and it hit the limiter, and then "POW POW!!!" REALLY loud backfire, sounded like it was going to blow a hole in the muffler.

I thinks it is a dual stage??? Does anyone have a link were these are for sale? I've seen the MSD ignitions with dual stage rev limiters, but I don't want the entire ignition....

Thanks.

warped stationary gears at 8000 rpm .. I don't think so - more problems from fuel cut, besides most buzzers go off before RL, it just give you an idea of shift point

Stock ECU has a perfectly good rev limiter. Are you doing this for the motor's sake, or just to be able to rev up the motor and get neat backfiring?

Rotaries don't mind accidental over-revving.

Ohhh, well since you guys say it won't hurt it... Then I just want the neat backfire

But I though 8000 RPM's was endangering stationary gears??? Still, does anyone know were I can get the noise maker??? My Blitz Nur-Spec is loud, but it could use a little "POW"

EDIT: And I'm pretty sure fuel cut is moved up with my Power FC. So no problem there.

Thanks.

Sorry if I missed something, but how does that make it a two stage rev limiter?

That sounds like he hit the rev limit with whatever ECU he has (PFC, Stock or what have you) and then had back fires down to idle. Or did he hold it on the rev limiter?

The PFC cuts fuel when boost goes .2 over a set boost range, not rev limit.

I think you just want the back fire. No rev limiter will do that. Unless I have missed the obvious.

The PFC cuts fuel at 8100 rpm by default. The stock ecu does it at 8300 rpm. You can adjust the PFC to cut fuel at any rpm you like -- this makes a great "valet" mode as you can set it to cut fuel at 3500 rpm....that will teach the little joy-riding punk...

your foot works pretty good. Unless you use a brick instead like all the liltte ricers arond here

the rev limiter on my pfc doesnt work too well lol I have it at 8,250 and I've hit ~8600 max several times in first

I have an ignition cut on my amp that sounds like a very safe way to slow down the revs instead of fuel cut I think spark cut makes more sense

Maybe I can have the ignition one at 8000 and the pfc at 8200

does everyone agree?

8000 rpm isn't going to hurt the engine, I wouldn't worry about it too much.

Off-topic: Nice sig turbodrx7, that movie is hilarious

i think he means a two step, what some drag racers use to spool up giant turbos off the line, it will pop and backfire a MFer.

i dont know who makes them though
