What am I trying to find?

I'm looking into fitting this on my turbo bike and for the life of me I cant think what its called to find out a little more about them!

There was a guy at Billing last year that had one fitted to his turbo drag bike to supply oil to the bearings and turbo before he started the bike.

Its a little (or not so little) expansion cylinder that taps into the oil gallery and fills with oil as the revs/oil pressure rise, when the revs/oil pressure drop the oil is then fed back under pressure to supply the turbo, in my case, while it spools down.

I don't plan to have a tap on it and keep it pressurised to get some oil flowing before I start the engine but if there is a small one made it could be useful to have just to feed the turbo while it spools down.

I just cant find what they're called!

Oil accumulator? Accusump?

That's the one mate!

They're quite pricey really, and bulky too.

And a waste of money! Your crank / rod / cam bearings manage quite well without assistance, the turbo has no 'special needs'!
