<< Thanks Bruce
 
 But this doesn't help me.
 
 I have a program called ENGINE ANALYSER that will tell me the runner length
 for whatever application or tell me HP/Tor for different runner lengths but
 my question is where exactly to I measure the runner length. valve to plenum
 or valve to throttle body ???? >>

Valve to plenum
