my 97 cobra has been good to me ,my old step up bolt on's with 150 shot of nitrous . made about 420whp and 485tq, i went 11.7 on nittos tires . my car is going in to the shop the first of the year,i just got a set of eagle rods and wiseco pistons ,my compression is going from 9.5-1 to 10-1 ,arp head studs,arp main bolts. and i'm going to go to a 2 stage nitrous set up 100 shot dry and 150 wet plate system, I'm happen to make well over 500whp with a good tune and maybe a 10sec pass..
