yes i beat a lightly modded 3rd gen from a roll. Also I raced a fully built greddy kit SI last night and it beat me pretty good. It was pistons/rods/sleeved/blockguard on 13 psi and dynoed 276 whp though. I pulled him about a car in 1st and 2nd from a 20 punch and 3rd/4th he came back and walked me hard. It's my first loss to a greddy turbo SI but the ones i raced before were all stock boost or near it.
