Yeah, just for giggles yesterday i switched from t5's to the dynoport i had laying around and DamN! no top end power at all, but great bottom end.
Ok, back on track, there is a guy 15 min away from me that has a 400ex modded out the a@@ Its like a 440 bore with a stroker crank, the only thing stock in the motor is the case. And my banshee would outrun it before i was ported! But i dunno with that dynoport
