tinygiants said:I got more info on this today. It is a little more than the bypass. In my motor, they installed a different gear rotor in the oil pump. This was not really documented very well in my invoice from Arrow Racing. So when I saw pressures exceeding 70 psi, I called Joe at PBJ. I replaced the oil sending unit thinking it was fouled. I still had high pressure, so I called Joe again. After conferencing with Arrow, we learned that they had in fact changed the pump set up to run at 70 - 100 psi. The only thing I have to do is be sure to use a sturdy oil filter such as the Mobile 1 or similar triple wall filters.
Tinygiants,
I see it has increased your oil pressure but did it eliminate the cavitation problem. I guess the real question is if you see it lose any pressure above 5500rpm?
