Not recommended. You should switch to the red pump.

i have noticed on every katech blue pump we have installed the pressure is lower then it would be with on a stock oil pump... i am talking about stock motors not built ones.. its not dangerously low, just noticeably lower

It has nothing to do with the oil pump because we do not make any changes to the pressure section of the blue pump. It is the same as stock. In the blue pump we are only making changes to the scavenge section.

Ls9
So is or is not the ls9 gm oil pump (2009+) an upgrade vs an 07 LS7 one?
Is there any issue with the additional pressure from the red pump on a system that does not have oil squirters or anything else using any of that pressure?

Ps jason I am in the middle of an overhaul and considering one of your pumps... Just hard to eat the extra 300 at this point of it doesn't really serve a necessary purpose in my N/A build.

Impossible. We are not changing anything on the pressure side of the blue pump. It IS a stock pump on the pressure side.

If you are using Clevite bearings they have higher oil flow and would be better with a red pump.

LS9 still uses a different oil pump than LS7, as we build them at Wixom. From what I understand the LS9 pump is indeed set up for increased volume to accomodate the 8 oil squirters. Have always wondered what the oil flow through squirters would look like at various engine speeds....
FYI I've run many LS7 & LS9 engines on the balance stand at work. LS7's typically have oil pressure about 80 psi at 1500 rpm's. LS9's run about 65 psi. So as expected the squirters do result in a lower oil pressure.
Note: there is a visible difference between the two oil pumps. LS9 pump has a hole in casting between the bolt holes on one side, LS7 does not. See photo of LS9 oil pump.

And if I need to change the oil pump, what should I be getting, a stock wet sump LS3 pump?
In stock form the V has shockingly low oil pressure (at least when compared to my Z) so I wouldn't mind seeing an increase but don't want to go too far beyond the GM spec.
Cheers, Paul.

While we're on the topic of piston squirters, I'm about to loose them in my CTS-V (I'm building an ERL sleeved shortblock using a LS7 block as a core)...does this mean I shouldn't use the stock V oil pump for fear of ending up with TOO much oil pressure?
