So out of curiosity and for my knowledge only, but on tuners you can adjust rev limits for neutral and in gear. Can you set the neutral limit to 3-4 grand and use that to launch?( meaning can i put the gas all the way to the floor and let it pop scream at 3500 and relase the clutch) i don't have the suspension or traction to launch my car like that but I've always seen msd rev boxes and was wondering if tuners did the job.
having a fine car that is slow is like having a hot girlfriend that won't put out!
I've tried it, and it works, but I would recommend a walk box from MSD. If you use the rev limiter, when you push the clutch pedal in, your engine will automatically drop down to 4000 rpm, which in a 1/4 mike race means lost time since it usually stay higher than that between shifts.
