Sure won't overheat, coolant keep flowing. Nothing wrong, just makan petrol becoz engine is running cooler.
IF you notice FC don't change, then ok loh.
@TryX: Remember the "wet flow bench" that was posted by Zelk long long time ago? If cam and valve design is so simple, then... many engine tuner eat grass liao. If dunno what that is, just google "Wet Flow Bench".
But, the formulas also got something wrong lah, the exhaust port smaller than the intake port, maybe the formula is for rocket engine. Maybe someone need to take measurement stock engine so can generate own formula??
Also, the valve size is not port size, which matters more... your valve big big but never do porting, also tokkok loh. So remember if wanna change valve, need to porting... this one need master skill. I just cincai paint the picture below to explain the formula lah... I'm going to eat briyani. Bye.
