Here is a good read for you on the stock auto tranny with up to 500 RWHP and over 25 passes at the track with 20 non-drag radials!

oh.. i dunno about that.. I suppose this also depends on if your mustang is your daily driver or not.. since it is mine I have to be cautious and lean towards not going so high.. 1 pass at a high PSI probably wont kill it.. you can ask modaddict about that.. for the track he always switches to a higher psi pully at the track.. but for on the streets he has to go down.. part of that is because it may not be streetable with the power he is running, but beyond that its probably also due to concern to engine damage running high psi around town.. and was that guys car only a track car? (or primarily?) 20 passes probably isn't much compared to daily driving it and getting on it (getting boost) more than 20x in your cars life span..

I've heard of people with autos with tranny problems at 450rwp or more.. so for me, I'll be cautious and stick around 400-420.. that will be plenty good for me..
