I've read in The turbocharger book that a turbocharger can be monted lower then oil level if a Scavageing pump is being used.

Has anyone heard of this?

I can call Grander and by an electric scavageing pump for cheap and mont a turbo at the end of each of my headers.

Any help would be apperated>..

 

Yeah it's possible. Good luck finding any room to put them below each header tho.

Lets just say there Is more room under the car then in the engine compartment!!
Plus I'll have 1 and 5/8 tuned headers which will give me tons of more power then the current kits that are not useing mandral bend tuned exhaust housings. Plus I can us all the factor exhaust to mount my turbo to it.

 

Don't forget that your axhaust will be 1 to 2x boost pressure, as opposed to barely anything when NA. This in turn makes the exhaust much denser, and throws your tuned header lengths out the window. Atleast they'll be mandrel bent. With turbos you also want the exhaust very short for faster response and better efficiency. Turbos run off exhaust energy, so cool exhaust is bad. My two cents.

 

has anyone ever put the turbos between the manifolds and the exhaust? do they fit ok? i just put a deposit on an 83 Z-28 and want to get my ghette turbo project underway. my setup will make everyone elses look fancy, mines gonna be super ghetto, just enough to ram 8-10 psi into the LG4.

 

Thanks for the input, I don't think I'll do that anymore!!
Also what whould happen to my engine if the scavaging pump failed?

 

The oil would not be able to drain back into the pan.

Turbo's would probably lock up on you.

 

I don't see the turbos locking up. The only parts that see oil is a shaft a couple of bushings/bearings.

I could see a lot of oil going into the intake side of the turbo, especially under part throttle cruise.

 

If you have the drain line plugged up the oil has to go somewhere, where is it going to go? out the seals. eventually the bearing is going to overheat & get damaged. I am thin'in anything that spins to 60,000 rpm is not going to line NOT having oil.

In on of the turbo books that I have there is a few companys that are using eletric pumps. To help pump the oil from the turbo back to the engine if the turbo is monted below the oil pan line.
In fact turbo airplains use an electric pump to pump the oil back to the engine. They do this becasue of space limitations and the angle of the plane.
SO it can be done! And I'm going to try to mont it at the end of each tuned header.
That was I will not have to do much welding!!

 

Mounting the turbos at the end of the headers is a big mistake. There are several key things wrong with the idea.

A) I don't care how much room you think you have under the car, you will lose one or both turbos on speed bumps on your first trip down the road.
B) Exhaust gas velocity will be lost to a certain degree by mounting your turbos that far out of the engine, but primarily thermal energy will be lost. Both of these factors will result in poor turbo performance, and killer turbo lag - you won't feel boost till 4000 rpm (by which time you will have lost both turbos because of a turtle in the road or some ****)
C) The last thing I'm going to bother mentioning - If both turbos are way back at the end of your headers, about the only option to run the intake piping back up will be right on top/beside the headers. So basically you'll be using giant hair dryers to attempt to boost your car.

Good luck with that.

I would suggest that you read 'Maximum Boost' by Corky Bell. It's full of practical info. READ IT

 

ok everybody is overlooking the biggest problem with the whole under-car-turbo. anybody ever take a big bucket of water and throw it on a hot turbo?
for those with no brain...
bucket of water=puddle(i dont care if you are not going to drive it in the rain something like the waterbox or a lawn sprinkler stream across the road will do the trick)
and hot turbo+bucket of water=cracked turbo pie!!! mmmmm mmmmm mmmmmmmm i loves me some cracked turbo pie!!

btw. encasing the turbo to protect it from water will not be a solution either.
