Bolt-on Track gains...?? Hey guys, just wondering what everyones experience was (track time improvments / horsepower gains) with a ported 90/90 (or 92/92 cuz thats what im getting but im sure there very similar gains) and / or and underdrive pulley on a cammed car with a stock ls1 intake/ throttle body?
