As for keeping up with F80s...if they are near stock, yes you'll walk them all day...if they are tuned, however, no...just no...i was lapped during the session by a friend in a tuned f82. Granted he was on cup 2s and i was on a/s3, but he pulled away on the straights.

Did your Harrop kit deliver ~6.5psi of boost during your track day at the Hockenheim ring?

Initially, i thought all was well, but when i went back and reviewed the video of the session, it looks like boost maxed out at at around 5.2 psi.

Chiming in, my last track day at ~100 ft above sea level i hit 7.5 psi. I have a p3 gauge that doesn’t track data but records the peak. I think only the second time I’ve seen that. On a hard pull down an on ramp or readying to pass, usually 6.5
