That sounds good but it still does not stop you from foaming your oil and thats the problem mostly. Maybe someone will make a big pan to hold more in the bottom but right now I still haven't seen any that seem that good. Even with an external wet sump these engines don't last long over 8000 unless its only sporadic drag racing use. There's a reason all the endurance and circle track guys go dry sump on the LS1 even though they don't have to on a regular SBC or SBF. Even on the ASA LS1 engines they couldn't make it work with the wet sump and they don't even turn that high an rpm. With the Dry sump of course they can work with no problems.

90psi??? Why??? Everything I've learned about oil systems (from SBC oval track racing) is that you want 5-6 gal/min. 40-50 psi is common to accomplish this. On leading dry sump systems people are moving to really small pressure sections (.8" or less) with really big scavenge sections (1.75 or more). And some scavenge sections with fewer rotor designs to optimize moving air.

LME's mods,which seem to reduce resistance in the oil system, would presumably use a lower pressure than a stock system.

No this experience is on cast iron...and each engine measures the oil pressure at a different point. But still, 90psi?

Thanks for the insight Erik, we'll talk more about this when I give ya a call about the heads.

Bryan, if i were to send you my block (having it built by a local builder) could you do the machine work and send it back with all the filger regulator fittings etc with instructions on how to get it all done. thanks

So is the stock LS6 oil system safe to 7500 rpm for limited use (non road racing)?

Sure as many many of us turn the engine up there or even higher for drag race usage. Now 8000+ isn't totally uncommon and things are harder and 8500+ and up there just simply aren't many people on here that can do that. Road racing and endurance racing the LS1 engine is much harder.

Our drag race LS1 engine at SAM makes power up there but almost none of this other stuff does. You're talking big cam high compression sheet metal territory. If you are pulling up there at 400 inches you are making the power to go 145-155 in the quarter on motor alone and I think we all know that that is not where too many guys are at right now. It's way easier with a smaller say 346 incher but still you need the right intakes to make power up there and you are also talking real valvetrains and ti valves and such usually.

Yes, because the pump is larger.

Yes. That would be no problem. Give me a call and we can set you up.

Thanks,

I'm talking over 400 ci with a solid valvetrain and forced induction.
