We set all our stuff up to leave at the lowest RPM possible and keep the tree green. The convertor stall is more critical to peak power and fall back RPM than anything else in bracket racing.

To me .03-.05 in ET isn't worth it to max out driveline components and not be in the hunt on the starting line setting a car up to need 4000+ launch RPM. Generally for a car to be REALLY good at any track year round you need to be about 3000-3600 off the Tbrake and off the pedal usually 2400-2800, any more than that it will spin somewhere sometime.

I gave up a long time ago giving this advice to racers that are teen and double 0 red at 4600-4800 and do everything but lower launch RPM because "I ain't gonna go out there and run slower!"....who cares? Loose convertors and 4.10 gears are your friend in most door cars. Gives you a big window on the tree.
