i got a 99 cobra that is stock and i want it to get in the low to mid 12's i am going to put a new Diablo Prediter chip 3.73 gears 120-150 shot of NOS full exhaust but no headers
what else do you guys think i can do to get my car there. (this is all becouse i got my *** handed to me by a 4 weel drive import) thanks for your help guys

I changed my mind i am going with a bad *** procharger kit

 

well, 1st of all forget the chip. 2nd you will need 4:10s instead of 3:73, 3rd you will need full exhaust, long tube headers included

 

Don't forget the CAI. And I personaly think the 4.10s are a little much on a daily driver. You lose first gear under normal driving and on the highway your engine's RPMs are a lot higher. Its anoying on long trips.

yes i know first hand about the 4.10s i screwed up there,and got 3.73s now..4.10s 80 mph at 3000rpms....3.73s ,92 mph at 3000rpms i drive fast on interstate,,so at 110 mph with 4.10 is 4000 rpms to much..
