No power...
Dear Sirs,
Steve is 100 % correct in all points.
Working on dynos every day I can't see any evidence for detonation in your sheet.
The TDC lift of your cam is good for a static compression of min 11,5 : 1 I would say if the squish is done right 12,5 : 1 is perfect.
With this cam detonation will just come up with very bad fuel, a very restrictive exhaust and a dramatic wrong ignition adjustment.
But !
The more your TDC lift the more your system gets reactive - so inlet plenum and exhaust must cooperate....then and hust then you will see power !
Best reg.
Dirk
