Limiting factory of the m44 motor?
I'm just curious if anyone here knows the internals of the m44 very well...
Question is, after studying the dyno curves that engine has to have quite a bit more potential waiting to be released... at higher rpms.. I want to raise the redline to more around 8000 - 9000 rpm and maybe re-do the intake manifold to accomodate the greater airflow, maybe short velocity stacks with ITB.
I'm wondering what the weak point is on the motor, what will fail at the higher rpms which need to be addressed?
Forged pistons, and a balanced crank obviously.. and a lower lift longer duration cam.. other then that, any advice? Previous experience? Valve float a problem, need higher spring rate valve springs? etc. etc. etc...
