Default Re: Spooling with Timing retard and fuel addition

In my car the rpm initially flares to 4300 then comes back down to 3800 or so as the VSC recovers.

Because I use drag radials this has worked better for me then using the 2 step since it doesn't hit the tires quite as hard. If you hit a drag radial too hard and break it lose the run is virtually over. This method doesn't seem to affect my 60ft much.
I'm not on a radial. And I mentioned that I use a dump valve.
I have had an incident 20+ years ago where doing some testing on asphalt with the trans brake and my finger slipped off. I can tell you that the car will move 20' faster than you ever thought possible. I only do it on stands now.
