Need to check after first road test

[240ZGL]

Just finished my first real road test and I have a couple of questions. I'm running a Hi Volume oil pump on Valvoline racing 20-50 for the zinc content. Is the normal oil pressure 80 psi because that's what I'm reading ? A question for you triple guys out there. I have an N42 with a E88 head, mild cam, headers, and 40 DHLA Dell's with 30 chokes on a Cannon manifold. It seems to pull hard to 4000 but above that in 4th I'm falling off. Do I need to go to 32 or 34 chokes ? What are you guys running ? Jet size seems to be ok, I had to bring it down from 140 to 130 because the plugs were reading rich.

If by high volume you mean the "turbo" pump, then yes the gauge reads nearly all the way up, around 80 PSI at highway speeds. I get that reading with 0W-40 by the way, so the viscosity apparently doesn't seem to affect the pressure that much. (at normal operating temperature, when the engine is dead cold I am sure it has a major effect.)
