I started small and kept increasing the size of the hole until my redline oil pressure was close to where it was prior to the oil cooler install. I don't know a thing about thermodynamical stuff but the idea was that at all rpm's, some oil could bypass the cooler to increase flow but not enough to reduce cooling significantly. Max temps are 10° hotter but I gained 8psi even with the slightly higher temperatures. I started with a 3/16 hole and ended up with 5/16. Oil lines are an10.
Can you post a pic of the hole location.
