Anyone having oil starvation issues?

**Nealoc187** · 07-14-2007, 11:44 AM

Wondering if anyone is seeing oil starvation issues during high G cornering? When and if my car ever runs again it'll probably be on a nitto 555RII or other similar streetable R comp for the road course and I don't want to burn up a motor. Anyone have any insight? I'm talking about VQ35s here, not sure if the oil pan/pickup is the same with VE/VG cars or not.

Years ago I was driving around a parking lot doing right handed circles like an idiot in my '98. I did notice that the low oil light would come on briefly at the peak of cornering. I think the car was a little low on oil and it just so happened to trigger the light.

Though nothing that I have ever seen on any road course. I just follow Matt93SE's advice and add an extra quart of oil before a road course event. All the events I've been to there has never been a low oil light on my '96, also you want the extra oil do to the loss caused by blow by at higher revs.

I'd have a custom lower oil pan spacer made before I started adding extra oil for fear of windage/foaming.

no issues here

No problems when oil is topped off.

In my Previa, when I take high-G turn, the brake warning light turns on to indicate low fluid, even when the fluid reservoir is full. LOL.

No issues with starvation, or with windage/foaming with extra oil?

I was thinking of making an oil pan or trying to add some baffling to the stock one.

I drove at Pocono in '04 a couple times, I've autocrossed several times since, no problems that I know of.

What do you mean by high-G though? Trailbraking at 90-100? Because that's what I did for a total of 2 hours at Pocono.

Either, but this car hasn't been hot-lapping...only autocross and aggressive driving through mountain roads....

Yeah that sort of thing on a mild R comp (no hoosier R6s for me). Maybe it's just not an issue for us. That'd be nice.

I wasn't on R-comps, and I was on stock suspension at the time...so I was rolling all over the place.

It WAS an absolute blast however..........

I thought bout using a ARC oil pan designed for a 350Z as I think it would fit- but the problem is, they are designed to hold oil around the oil pick up screen during a turn. Where if you mount it on a FWD VQ this would mean oil would be there durring high fore and aft forces like braking and accelerating.

I have been runing my VQ with 4.5QTS of oil all its life, never been a issue with foaming, nor have I ever seen the oil light flicker. 180K on mine.

From my previous experiences with my B13 SE-R, I would run a bit over full to prevent oil starvation during heavy lateral forces. SRs tend to spin bearings quite fast if you run them low on oil.
