I just want to know how many of you guys are at 500+ plus on a stock bottom end. Currently I'm heads/cam(N/A) and thinking about havivg a custom turbo fabbed for me. I'll run low boost til I get it forged. Right now I make 417rwhp 400rwt in an A4. I figure even on low boost I'll shoot for 500 at the wheels. Will i have to forge the bottom at those levels if going FI?
thanks

Weve made 550/500 at 8 lbs, car got roadraced at 3800+ lbs and beat on for a while (cam only with D1SC) End up making best of 640s with 11-12lbs, before it was taken apartfor a real motor, shortblock looking better than most NA ones we end up pulling out
