as above really i have a 2wd saph cos which has had a full rebuild about 9k ago running stage 1 running 18psi with a radtec 500 cooler 3 inch mongoose system k&n filter. I was just wondering what power i would be running now and what sort of power i would be looking at with greens 3bar and a t34 .55. Also what is a safe amount of boost to run with the last spec cheers
