My Trans Am is a 99 6 speed, mod's in sig. What do you guess my 1/4 mile time would be and what would my horse power to the wheel's would be? thanks

 

from the 100s of dyno runs I've witnessed, I'd estimate 310-315 rwhp, and low 13s since you have a heavy Trans Am.

BTW, that Flowmaster muffler actually shows no gains over the stock muffler. I'd dump it and get a better 3" catback and pick up another 10-12 rwhp.

Yeah i agree with nine ball. Probably run some mid to low 13s depending on your 60ft.

 

Well these guys have it covered pretty well.......but i'm gonna guess 12.93 @ 110mph but you better cut a 1.9 or less 60' to see 12's. And i'm gonna go with 325rwhp. Good luck.......BTW you need some nittos

 

Thanks everyone, I know I should get ride of the flowmaster but I really like the sound.

 

F*** it. Keep the flowmaster and just get a QTP cutout!
