Ugh, more oil pressure woes, pressure is dropping at WOT now..

Aren't cars fun? I just got done replacing valve seals and got almost all the oil leak fixed I think.
Hope you get your oiling problem figured out. Like Shon said drop about half a quart at a time and see.

Your pressure relief is opening at that RPM and bypassing the oil.
I didn't think it would do it but I'm wrong. Ya going to have to put in a stiffer spring.
Call whoever made the pump and get their recommended spring or I can have ya a pump built that won't do that. (same people I use-- about $110.00)
Not too much oil either.Just when the relief opens it bypasses to much and knock's the pressure down.

LR,
Is there a pressure relief within the pump? I know that the 1060R filter is supposed to not even have a bypass valve in it. Didn't know which you were referring to.

Thanks Larry, I had a feeling there was something "opening" all of a sudden and releasing pressure.. the autometer gauge shows how freakin' fast the pressure all of a sudden drops on me...
I know the spring in the pump is a purple spring.. I've heard alot said about a "white" spring.... hmmm.
It's a Melling M55HV pump... I guess I'll give 'em a call!
Will a different spring also bring that high pressure down at lower RPM's? It seems way too high when I'm cruising (60 psi)... wouldn't that rob the car of power too?

No 'cause the relief isn't open then,well maybe on a cold morning.
I thought ya had loose clearances in this engine?????
Melling can get ya fixed up with the correct spring. Talk to a tech/engineer and not a salesman.
Ya may have to run a straight 20 weight in it till ya get a few miles on it.
I run them with more than 60psi. Some go 100+psi out the back door.Idle at 40+10psi x 7000. Can't do that with a hyd cam.

Ya running a hyd cam?
All that pressure indicates not so loose. Ya got a HV pump not a high pressure.
When I say loose I mean .0025/.0027 on the rods and .0027/.0030 on the mains.

Maybe I should be calling the engine builder, finding exact clearances, and talking to him about the pressure issue huh? Maybe I shouldn't even have an HV pump in there?
I'd be happy with my stock oil pressure back lol

I'll see what I can do about contacting him tomorrow... then I'll contact Melling!
Thanks LR for all your help so far! (i say so far b/c i'm sure it won't be the last!)
