Turbo kit interest

Years ago when GReddy started doing this I debated how it would work, but it has long since been proven so I will test it on the ti.

Excellent idea that I considered but without the "banjo" fitting. I was going to modify a oil plug but that would be a pain every oil change. The Banjo is a perfect solution. This would also take away the upward curve in my turbo oil dump. Please PM me the parts numbers when you figure it out and I will test it on my car immediately and report back.

Yes John, since simple and easy to install is the objective here, I think this will be the way to go - I will see what I can dig up.

Way to go guys. Good solution it seems. Hope to see it work. How will the flow be tested? Just wait to see if oil spews thru the bearings?

If the car smokes like it is burning oil there is oil leaking past the turbo seals. I know exactly what it looks like from when my scavenger pump went bad and also when I had the turbo oil dump hose oriented wrong and oil was backing up in the turbo. The boost pipe also gets a nice oil film in it when the oil dump is not correct on a turbo.

Well there is a little more to it than that, while it is true that you could just see if it smokes, I prefer to test these things.

I usually test the oil volume exiting the cartridge, then we will know if there is: a) enough oil or b) too much oil and require a restrictor (or smaller one)

Second is that I would temporarily use a clear hose to actually see if the drain is backing up on the turbo.

As I said the setup has been long since proven to work on the H22 (also a "slant" motor)

I run 90psi cold and 60+psi oil pressure hot with no restrictor bung. Think that is too much? No leaks and cheap EBay turbo

A turbo road race car I worked on I had to upsize the drain hose from 1/2 to #12 aeroquipe to handle the drain. If you let the drain hose drain to a bucket its not oil its oil foam coming out, the foam backs up easily. It does not have to smoke, until it fails....

I would try and come up with a above the oil drain, it allows the natural vacume in the crankcase to help scavenge the oil.

It likely depends on how the car is intended to be run as well, most turbo cars don't regularly run at flat out full speed for a half hour straight...

I know that air research used to say more turbos were ruined by over oiling than under oiling.

Great idea would be very interested if it works out

[angus]

I think the idea here is to control the oil flow into the turbo - manufacturers like greddy will spec the turbo with an orifice that is appropriate for the application when building a kit.

This way you will not need an oversize drain or need to rely on crankcase scavenging to drain the turbo properly.

The drain plug oil line obviously works, and sure makes it easy for DIY'ers - this is a big plus for my kit.

The race car I was referring too had the problem stock (And it had a metering pill). I think it really had a lot to do with time spent at high rpm, we were keeping the car up near 5000 pretty much continuously and in the corners the oil would pile up against the drain, the factory drain hose also had a sharp bend in it. so multiple oddities were linked to the issues we had.

I've worked on a quite a few turbo engines, and I've never seen one drain straight to liquid, some even have a baffle can to allow the foam to disperse. Not saying it wont work ,, just that its not the usual trick. With a metering orifice I could see it dropping the volume, that may be the whole fix.

Incidentally if yhou need metered orifices, check dirt track suppliers for Mechanical injection fuel pills, they are nice little brass pieces with very accurately drilled hols in a extremely broad range of sizes.

Good Luck!

X2 !

Well? Santa's gonna be doing his rounds soon. Will he be dropping turbo's down the chimney?... or coal?

[dguzzardo22]

So Is the thread dead ? There is no turbo kit ?

[planksta]

"ANGUS," please do this, it would be awesome, id be super interested in a plug and play turbo with a gain like that, that **** would be killer!!
