Oil Surge

[lazyitus]

What are the best ways to prevent or reduce oil surge on a twisty track ?

Any hints or tips for reducing the chances of really bad damage ?

Baffled sump or go slower round the twisty bits...

Add more oil. Baffled sump. Add an oil accumulator. Reengineer the oil ways so the oil doesn't accumulate in the heads so much under lateral G. Fit crossplies.

I use a 'pressure accumulator' (Accusump) and, whilst a bit of a bodge, it does work.

Word of advise though that isn't in the manual. You MUST blead it before using it on the track or you won't get the full benefit. I didn't, I blew up.

I suspect driving a few on roads would be sufficient.

Ideally you would go dry sump but this would cost about a grand. However you would be guaranteed never to have a problem and there would be a useful power increase.

If it's an rv8 then a group A trap door, big winged sump is about the best wet option. Otherwise, weld in some baffle plates.

Thanks guys, some good tips.

I have a raceline cast alloy sump on my Zetec SuperCat. it is baffeled and has not problems with oil surge. But it does cost £450+, but well worth it and I would buy one again if needed

Our Formula Student cars with motorbike engines can suffer terrible oil starvation problems as they are not designed to experience lateral loads. Welding a cylindrical baffle into the sump to sit around the pickup was the solution and one (fingers crossed) that seems to have worked very well.
