Alright i'm going to the track in the next week or two to truly test out my new mods, but the first time i went this year i ran a 15.63 @88mph, and that was with a WAI, cat back exhaust and upper engine mount.
Since then i have installed the lower engine mount and an 18oz aluminum crank pulley, not under drive stock size just a lot lighter than the stock 4lb 7oz one. I was hoping to run below 15.5 with these other two mods, what do you think i'll get?
It's possible...but you never know if the track conditions are gonna be better or worse. No 2 days are the same.
you can actuall run worse, depending on track conditions
