you are simply incorrect.
red tiger engines have a higher oil pressure relief cracking number than an N.
while a fresh N should top out around 45.. it's not uncommon to see 55-60 psi cold start throttle on a red tiger that is healthy.
Also not uncommon to see hot running pressures inthe 45-55 range for a healthy red tiger.
I've got about a dozen in the barn to back that up.
