Default C6 oil pan vs. C5 oil pan??

I spun bearing last weekend do to oil starvation. My understanding is that a C6 oil pan might help this problem. What do you think? It cost $400 for it.

thanks,

Steve A.

I have heard that the C5 bat wing pan is better than the C6 pan. but the only real solution is a true dry sump, not the OEM "kind of" dry sump

If it is for the car in your avatar you will be wasting your time with anything but a dry sump. Cars with aero need good oiling systems.

Default pan

Accusump with LS6 and batwing

Dry sump with LS2/ LS3

You may survive with Accusump LS2/LS3 but grip (A6's, Goodyear AC's), high rpm's and any aero exacerbates the issue.
Dry sump is expensive but what is an engine or crash worth.

With an Accusump is there a kit you buy? I read some thing about manual or electric.

thanks,

Nope... C6 pan is worse. How'd you loose oil pressure auto-xing? Usually it's sustained high speed sweepers that hurt these motors. LS1/LS6s are quite robust. I've been racing mine over two years (3k miles @ 122k miles now) and never had oil pressure issues. I run a LS4 high volume pump and Amsoil 10w40 FWIW; no accusump.

Looks like I should stay away from the C6 pan. We had one left hand turn that my motor was around 6600 for some time. The shop where my car is, told me that it was from oil starvation. I just assumed that's what caused it. I've done many of these type of turns before. So really, I'm just guessing and maybe they are too.

I suggest sticking with the stock LS6 pan or going to dry sump, and as mentioned in your other thread, for auto-x with aero, I'd consider a 30 grade racing oil.

I think I have three years worth of data from Thunderhill in my '06 LS2 that clearly show oil pressure through T2, a sustained left-hand sweeper, getting lower and lower. If I overlay that with my terminal velocity on the front straight it also gets lower and lower.

This is a car with no aero, on 275+305 R888s, with coilovers & swaybars.

New motor went in last summer...

You can find ARE at drysump.com. Using a accusump is a crutch that works for some. It will not work at some tracks. Tracks like Road Atlanta and Mosport will definitely have a problem along with Roval tracks. I personally know of more than a few aero cars that lost the engine at Road Atlanta and they had the LS6 pan and accusump.

Steve,

You can buy from Canton. I have used both manual and electric (on more recent cars).

One of the keys in making Accusumps more effective on LS engines is drilling the lifter trays and using restricted pushrods. I have had very good luck using an Accusump on LS6 and LS3 engines with using the above methods (i.e no blown engines). The main problem with LS engines, and more specifically LS2 and LS3, is oil pooling in the heads and upper portion of the engine.

This is also not to say that a dry sump is the real solution.

I ordered a Accusump. Seems like that should work for me. Seeing that I've gotten away this long with nothing. Thanks again.
