Has anyone tested underdrives, TB, upper, o/r pipe (before and after et) on non pi motor. Im starting a new project so learning from others helps me save money and time. please give name brands on parts because all parts are different. thanks
Well what is your goal with the car? Are you planning on getting a supercharger later or staying NA? MMFF magazine is running a series with a NPI GT and tested most of the boltons you mentioned with before/after dyno etc. I suggest picking up those issues. And a PI swap is definately a good way to wake that car up.
I will just add bolt-ons for now I'm looking at the zex kit but I want to see what UD, X pipe, TB... will do Im already running 9.6 in the 1/8 with a stock auto convertible but dropping another couple of tenths would be nice.
