I know it needs more lift, and I´m going to replace the 1.5 rockers with 1.6 ratio rockers to help it out a bit. I dont want a roller or higher CR because it would make it less streetable. It also needs shorter gears but I´m not gonna do it for the same reason, a lot of compromises because I drive it on the street. I drive it also to the race tracks and it has been trouble-free.

I must also say that I have only 4 passes with this engine on a proper race track, those are the ones in the video I posted. And I did not make any tuning at the track. I mostly race on airfield tracks with no track preparation.
