I was told by Marv at A-1 trans that you want the absolute stall speed to be right on peak torque after the shift.So when you shift it lays on peak for a second(just a term)then start locking up from there.That should net you the best results.


I understand that completely.
What do you launch at is my question?

Most everyone I have heard launches at peak stall. I think that is wrong!



In my case I never used an auto until I went legit street car racing.I use Nitrous.I floor it right on the trans break(haha)no limiter(4200-4700 depending on air quality)let go of transbrake and nitrous turns on and away we go.convertor goes to 6800-7100 rpm.

That is what they( ATI ) said not to do?
This is why I brought it up to inform the people on this sight!

Marv never said I shouldn't do that.Also I have only broken 1 convertor and that was a snap ring failure.If I limit rpm by rev limiter there is a better chance of burning a piston,dropping cylinders ruins airflow within the manifold making fuel distribution inconsistent. This is based on my experience with my combination.



If you limit rpm,then hit with NOS,it will also run harder at convertor making the initial hit more violent.
