Topic: So I'm going to run a turbine engine off my CB750K8...

[specialone70]

It's built from a regular old Garrett turbocharger, so it needs oil flowing through it. That's where I'm not quite sure what I'm doing. I guess I'd tap into the oil flow the same way people put oil coolers in line with the oil flow, but I'm not sure where or how people are tapping into that. Then I'll want to also actually have an oil cooler in that same line with the turbo, and probably a pressure and temp gauge. So my questions are: How/where do I tap into flowing oil? What kind of oil cooler should I use (I keep seeing the name Terry)? Can I get oil pressure and temperature gauges that just go in-line with the hose to or from the oil cooler? I can't seem to find any.. Thanks.

Just my two cents. I think you my have to use a auxillary pump some how. You could use the outlet that we use for the oil pressure guage. I'm sure someone running a turbo, will chime in.

Dude, I'd suggest using that handy google search bar above on the left, turbo projects are a pretty big undertaking,  and oil lines are just one minor step in accomplishing the task.

From what I understand aux oil pumps are often used, and a return line may be needed to be tapped into a pan or oil tank.

Best of luck.

A you using it as a turbocharger on the 750 or have you converted it to a gas turbine engine?

I am also confused by the thread title? You are going to use a CB750 engine to somehow power a turbine engine or you are going to run a TURBO ON a Cb750 engine?

To clarify, this is basically what I'm making: https://encrypted-tbn3.gstatic.com/images?q=tbn:ANd9GcRecbHoILNV62Va4h-ED1JfydU5RwxyxL1rRmp3wvG51aiFwNvJ5w

It won't affect the motorcycle's engine at all, it'll just take advantage of it's oil system.

It didn't occur to me to search the forum for how people oiled their turbochargers. I'll have to do that.

To Reply, I havn't put a turbo on a motorcycle engine, but I have done other engines. Current turbo project is on a jeep 2.5 liter inline 4 motor. And yes, these are all built by me. No kits.

Tapping into the high pressure side on the engine for supply line is perfectly ok. I have seen that location is on the right side of these little engines. People usually add a oil guage to this location.

As for return line, try to keep it short as possible, straight as possible, with little restriction back to the oil tank. The tapped in return line at the tank MUST be higher then the oil level at running condition. If you don't have it higher then the oil level, you will have some serious problems.

Also, you didn't post what type of turbo. Did you ever factor size of the unit to the amount of CFM the engine runs at? There is alot more to a turbo system then some may believe. (Yes, I have actually done calculations to size a turbo to a engine with required performance.)

Nevermind all I said: I clicked on the link. Put I do stand on my oil return guidelines.

So you're going to run a 750cc engine just to power the oil pump so you can then run your turbojet engine?

Excessive much!?

I would be looking into sourcing an external oil pump driven by an electric motor.
