I pulled 13.8 @ 103 in my 95 Z28 last year with Flowmaster muffler (stock exhaust other than that), Moroso cai, and Hypertech tuner. I also have over 160,xxx miles on it. You should be solid mid 13’s as long as you can get traction and a good launch. Let me know what you do. I always like to see what other people are running.
ya that sounds right.with just a SLP loudmouth and ram air hood and air box iv done 13.86 and i raced last weekend and did a 13.89 on the brakes but i still lost in the 3rd round…didnt hit the brakes hard enough…
