PSI "D" is 422 cu.in.per/rev or 6.752 liters per/rev

PSI "C" is 476 cu.in. per/rev or 7.616 liters per/rev

That's a fair price.... did you run the D or C on your car for the 6.11 pass?

I talked to Justin yesterday about past engine issues, and his CV1 combo...We had a good talk, and I learned a few important things...

He was cool as hell, no arrogance at all...It was cool to hear what he had to say in person...
