Default Bolt on Lt1 Trap Speeds...

I have a 1995 Formula with 170k miles and i have Pacesetter Lt's, moroso CAI, borla catback, and 4.10's...I was just curios if 83mph is a good trap speed in the 8th for these mods?....my times are crap 8.93 because of my 2.2 60's...

A4 3.23s trapping 85-86 on high 7 runs

I'd think a 4.10 M6 would trap a bit higher
any weight reduction?

I have a few more things done then you and run a 7.82 @ 86 with 1.65 60's, so you should be about right for your mods...

get a better launch and some suspension and a tune and you'll be in the high 12's.
