Bill,
I can't see a response from Lynn, but I would be surprised if a larger inlet didn't = Greater VE= more power through the entire RPM range. The street port is conservative at any rate.

I sure hope somebody comes up with an explanation for coolant in the rotor housings, as I can't find one!  I tore down my engine because of that, and could find NO o-ring leaks.  If it leaked, it didn't leave any evidence.  The system would hold 15 psi pressure for a week or so, but would slowly leak into the rotor housing.  Up to temp, it would blow air into the coolant system (equal opportunity leak).

Didn't find the coolant leak, but did find about 3/4" of one of the side seals missing.  Now I am gathering parts to put it back with '91 rotors (need a rear counterweight), and looking at street porting.  Does anyone know if there is value in street porting if 6000 rpm is the highest you will see?   Lynn??
