Re: A4 LAUNCH (Face)
It hard to judge, but I have knocked off .05 -.15 depending on traction. With the PT-2400 it is hard to power brake and hold it at 1500 rpms without the car moving. A higher stall converter should not have a problem. The higher I take the rpms, the harder it is to get traction, the drag radials have to get really hot!

on drag radials I don't recall seeing much difference in ET or 60', however, big difference in RT which is more important to bracket racer.

Re: A4 LAUNCH (RWhite)
Face, what wheels and tires are you using? I sure want some black rears for my black ‘Vette. I now have zero traction :D with my new 3500 rpm Vigilante!

Re: A4 LAUNCH (MikeV)
With my Yank 3000, I can't see a difference in time either way on a hot day. I have tried many difference rpms and have the same results. On a cold day 60 degrees or less, my best results are to run it up to 1500 and let her rip. Drops the ET by .1, Usually I torque it to 1,500rpm on launch anyway because my R/T is better. I use 275/17" Nitto Drag Radials on my old front wheels.
