Racelogic Traction Control

? ...I meant limit rpm to say 5500 or 5600 while you have your foot on the gas and the clutch at the same time so that you're not dropping into the next geat at 7k rpm and having to shock your driveline much harder.

Hey if no one around here has destroyed a tooth just dropping clutch close to redline, then I stand corrected lol. I come from a world of subarus and porsches...i've seen too many teeth stuck to the magnet on the drain bolt to even attempt this in the Z haha.

If these cars are this durable i think it's time i just get a heavier clutch and start ripping those launches at 5k

I think Charles was taking a dig at my shifting speed. haha. Touche. He has the time slip to prove what hes taking about.

The only thing with launching hard is that horrible rear axle hop, which bushings will help with, I am yet to do them however. You will smoke your tires well before you smoke the trans. The stock clutch however, not so much.

Nah I have never seen you drive, I am just debating the purpose of even having a no-lift limiter unless its purpose is to ignition cut or retard and burn fuel in the exhaust for a couple pops of turbo spooling inbetween shifts... but I dont know that any of us are running enough turbo to need that.

Realistically what it's supposed to do is keep you from hitting the rev limiter between shifts. Maybe I'm misunderstanding that you're misunderstanding but, with it present when you push in the clutch the engine rev drop down to 5500 or 5600 almost immediately to keep the turbos spooling at optimum boost levels for the next gear (you want your revs to match where your torque is high and your next gear engages)

if you're at the rev limiter you're past peak torque for sure and most likely already out of the turbo's efficiency range.


I had this system set up on my wrx and you can feel each gear just pulling you harder...and harder...and harder

I know what you meant, and I am saying it doesnt make a difference (in my head, at least). If you are no-lift shifting the car, are you going to push in the clutch and then sit there and wait for the engine speed to come all the way down to 5500? I'm not... defeats the entire purpose of no-lift shifting.

Unless you are granny shifting like that, engine speed probably would never have a chance to fall below 7000 before the clutch is reapplied and the engine is braked down for the next gear speed.

Sure anything can break, but all that you realistically need to worry about is the axles and differential mounts. Replace the diff mounts before the rear one busts open, and preload your axles before launching and you probably wont be unlucky.
