Put in lighter oil first and see where its at... all
that pressure is just eating power

Swap in a standard volume pump. You are just wasting power recirculating oil with that high volume pump.

I'm not buying that argument at all.

I tried a back to back run deal years ago.

Ran the car with max oil pressure and 20W-50 oil.. 100 psi.

Then drained the oil and put in 10W-30 in it. (both synthetic and same brand).. Also backed off the oil pressure with the adjustable spring. 70 psi.

The car went actually slower by .005.. And that was just due to the difference in DA..

You may see a difference on the dyno, but you wont see anything on the race track..

Just my

at what pressure do you blow thru the bypass in the filter?

---

Good question Ray..

I have used both K & N and System 1.. Don't know what the bypass is on either..

I just did that test years ago to see for myself.. I was always told that all that oil pressure was slowing me down sooooo much..

Not True..

My B1 now has about 90-95# cold and through the traps. But goes down to 35-40# @ idle after a run..

Sorry to jump in with a question: But my new 408" has what I would say unusual high oil pressure...75# - 80# at idle completely warmed up....I switched from 20/50 to 10/30 as suggested in another thread and it did lower it to 65# - 70# but still climbs to 100# as the rpms climb? It does have a Mellings HV pump and also we threw a 90* oil filter adapter on it as it was all we had lying around....it is untouched (meaning it has never had any of the neat tricks I've read about done to it to improve flow). I also run a Wix 51515R filter.

Could the 90* adapter be the problem or at least part of the problem...??????

Or am I just overly concerned...??????

Thanks in advance,

Rickster

Doubtful on the 90* filter mount... my big concern
would be possibly blowing out a filter or filter
base O-ring... I ran a stock 90* mount and never had
any where near that pressure

Motor seems to be getting plenty of lubrication where neede.

I had the same problem on my 416 with the melling HV I took it off and threw it in the trash and went with a standard pump problem solved.I still have 35-40 at idle with oil at 160 and 80 in the traps.

Having never used one I wasn't sure. I could just swap out to the standard pump I guess.....my engine builder said not to worry about it so I probably won't.....my 565" in the vette alway ran 65-70 at idle and up to 85-90 through the traps and never had an issue.

Didn't think the filter could blow out....isn't there a pressure regulator valve that keeps that from happening...???? Showing my ignorance today
