Hello all. I am new to this forum, and hoping to get some information about modifying my 2002 Grand Prix GTP. I am looking to cut down on the 1/4 mile time and at some point am considering upgrading my Supercharged to the Turbocharged, along with other modifications.
I just wanted to know how much horsepower will the stock transmission tolerate?? TIA.

Welcome to AF.
What are your current mods?
Companies like ZZP have tested the 4T65E-HD tranny for a duty cycle of mid 13 second 1/4 mile times. That would equate to around 350-400 engine horsepower. After that you are on your own luck and it is a ticking time bomb.
