Here is the deal.....

Got beat by a 03 cobra by about 2 feet. Need to know if this is hurting my performance....

My headers are leaking by the part where it connects to the heads in 2 different places and it is leaking to the piont where flame come out a little. How much if any is that hurting my car..

If I do these things how much Hp would this improve my preformance(to he wheels)


Advance timing by 4 Degrees
put 110 oct fuel in car (put fuel in ice chest all day w/ ice to get the gas ice cold)
remove catback (open Ypipe)
Fix leak in headers

 

whats your 60 ft time...... if its high, thats prob why he won..
