Oil Pump :: HP vs HV

[LC]

I'm getting ready to tear apart my M6 car, just missing the oil pump.

Normally I would let the stock one live for such small mods but with some people having problems with them I was going to order a melling one, however the vendor asked

High Pressure or High Volume

and I froze.....


Builders any help is appreciated, or any other brand you may suggest?

High volume is my choice generally. Especially when building a real radical build where I run the tolerances a little on the loose side.

Well everything is going to stay stock.. it's just heads/cam/rod bolts..

Most people run the Melling High Volume unit 10296 with the standard pressure spring, that's the one I'm going use, I think.

The Melling 10295 is like a stock unit standard volume that comes with a high presure spring 10lbs more than stock at all RPMs.

Either way Mellings are real good units

Well I chickened out and bought a Katech one...

And reading about horror stories of ARP rod bolts I bought some Katech ones too..

Melling HV 10296 is all we use/HKE in our speced engines.
Ported and shimmed oem OP's are not what we recommend to our engine customers. They are a big money maker for the people selling them, but they are not what we would use. I've sent back 2 this month alone to the customer and provided them with the Melling instead.

Maybe I talked to the wrong people but they said that the 10296 was better used for a higher tolerance engine.
They also said the HV could dry the oilpan in a sustained high rpm lapse.

I know a drag race takes 10 secs (toretto style) but imagine going 155mph for 10mins...

Anyway

No one sells a bad product I guess...

Only 155mph. Try going 270km/h from Cul to Maz, lol.

What up man? How are your builds going?

BTW, the 408 in the Silvy has a shimmed LS6 pump and the Camaro a stock pump. No issues with either and they both have heads/cam and other bolt ons.

Cul to Maz at 270, I bet you had some escort there

The builds are going ehhh slow...
About to start the M6 car just now and the A6 car is on the garage without engine and the trunk full of parts :emoticon7:

How is the red camaro doing? any runs yet?

Their were eight cars total but only us and the BMW X6 M were doing that. They tried to stop us three times but we were too fast and the cars behind us stopped them and took care of it.

The Orange Camaro was wrecked coming home from the track in the rain on the DR's. Haven't raced it since I ran the 10.9 but were hoping for 9's next.

The Silverado should be done soon and I will be driving it down there early next year probably in February. The Hemi should be done soon too.

We always use a ls6 style pump, ported and pressure raised in-house. Never a problem from a stock car to a 7200 rpm, 900 rwhp setup. Our engines are built tight though.
