Well i am running the keith black 12:1 compression pistons and i thought about running the forged, but the pistons i have are 30% silicon and since that means less wear and tear and less resistance it is better in the long run for N/A cars. I was thinking about putting a 75 shot on it when i break it in and need more speed but i would not go more than that. The pistons have been through hell and back, they had been urning coolent, my cam stopped spinning and the pisonts held up to the beating of the valves really good, so i think that you should be ok... but dont put anymore than 75 shot on and plus the pistons are lighter so it gives it a quick rpm pick up. The keith blacks are some damn good pistons!
