Great day guys and good to meet up with many of you,
RCM dyno 516 bhp
Sumo 518 bhp
Checked out the correct formula and you divide the wheel bhp x 0.8 for turbo charged, 4x4's.
This would indicate both dyno's to be slightly out as the formula suggested 525 bhp.
To be honest I don't give a 5hit
............. but I did when I saw the front of my P1 start sliding off the rollers
