Hi rpm oil starvation

Elmo370z · 02-08-2015, 11:29 AM

Dry Sump will solve that problem. Initial cost expensive, but worth it if you plan on tracking the car and sustaining high rpm's

How about a baffled oil pan? Like the one I have.

Lets point out that your pan is not simply baffled, but that it has active baffles!

Big, huge, epic difference. A static baffle will block fluid transfer just as well as it retains it, and in a pumping system a static baffle will only promote pickup starvation rather than cure it as the pickup will deplete the reserve fluid immediately and the baffles will slow the refill.

This is also why designing fixes for fuel system starvation is NOT as easy as everyone thinks.

Yep, there is 4, one-way trap doors in that pan.

It appears that the surest non dry sump solution to oil starvation available today would be the GTM pan with extra oil capacity and active baffles. Also the increased surface area of the pan will offer a little extra cooling relative to the stock pan. If the conditions of operation (rpm’s, oil temp) remain the same for the new pan, the oil change interval could be lengthened too.

Thanks for all the inputs to this thread.

Well, the GTM pan doesn't have active baffles. And good luck on getting anything from GTM.

Rusty, where did you get yours from?

My oil pan is from AM Performance, which is no longer in business.

I got mine from Shamu when he was rebuilding his engine, and went with a dry sump system. Think there was only about 20 of the oil pans made.

Not sure what is meant by "active baffles, but the GTM pan has one-way trap door baffles that help keep the oil at the pick up tube. It's a great pan from a lousy company.

The pictures of inside of the GTM pan that I seen, just had the baffles cast into it. Didn't see anything that looked like trap doors.

Too bad it's no longer available
