 I know, Bruce put in a standard oil pump. And should have put a

   I ran a 12-A for quite a while and it ran at 60 psi and they have a
real small pump compared to the standard 13-B and I also ran a 13-B
with the stock pump and it ran at about 70 psi, I now use the turbo
pump and run at 70 to 90 depending on the temp.
