K&N PS-3002 for LSX454?

[jetjock15]

Thanks for looking guys, I log on here every few years cause I know their is some real credible info on here. I understand how important oil and filtration is, so when I am doing something out of norm, I like to run it by you.

I am putting a new engine in an off road race truck. Its chevy's crate LSX454. I am running a top speed pan with no filter in the factory location. The external filter is set up for a K&N PS-3002. Previous engine was a big block. I googled LSX454 requirements and think I read 10 micron, I googled the PS-3002 and it says 10 micron, so I think im good there. However one search pulled up the PS-3001 (a similar filter with different threads) and on summit it shows relief valve at 8-11PSI? That doesn't even make sense to me but again I don't claim to be knowledgeable on these topics. I just want to make sure the K&N PS-3002 will filter to the right level micron, and not bypass, with this setup. Standard LS oil pressures 30-90 psi in various race conditions.

Thanks as always for the expertise and opinions!

I don't know the specifics of the LS architecture, but an 8-10 PSI bypass is pretty typical for most oil filters that have a bypass. I think stock LS engines may have the bypass built into the engine, but you don't sound like a stock setup anyway.

Remember that the bypass valve only opens when the differential pressure across the filter reaches 8-10 PSI. It doesn't matter if the oil pressure is reading 30 psi or 300 psi, the bypass valve won't care. It will only open if the filter inlet pressure is 38 psi (or 308 psi) and the output pressure is 30 PSI (or 300 PSI).

I believe the 8 - 10 PSI is the difference across the media. I think they call it "Delta-P".

oh nice, thankyou, that makes a lot more sense! Yes, nothing stock about anything its a tube trophy truck style chasis, there is no stock lol. Thank you!

The air filter is the most important filter. Any quality oil filter that specs out will do.
