Bearing in mind my engine has vvt so you gain alot over a standard engine anyway so these injector positions and trumpet length dont have to be spot on optimised, the vvt gives you the drivability and tourque down the bottom that you would normally lose with having inlet tracks and injector position tuned for top end power. You have to come to a compromise as mines being a road and track engine and thats what the vvt allows.

You can sit the engine at 9000 rpm and with the touch of a button advance and retard the cam timing watching it pick up power
