Tanks guys! our struggling continued, what else. Set to kill, it run for 0.3 seconds and something broke in the trans. Took the trans out and tore it apart and back together. Got 30 seconds left to get in to line up, but no boost; at least we know now that at 7 psi it runs 9.0/154. Will never try that again. Then we till got an opportunity in the nights race but the result was the same; the car starts creeping against the trans brake and propably the front band is gone again..., Maybe we'll check that tomorrow.
Again, thanks for your support, despite of all the troubles it has been a pleasure!
