Roots charger with twins

Mika · 07-18-2008, 01:33 PM

This is just in planning stage yet, but will probably come real next winter.
I have now GT40/47 twins in truck, but I think Eaton M112/GT42/GT47 would be some cool combination for big power and fast response in lower rpms.
Any ideas or suggestions?

I will spam this thread full of pics if I begin to work with it

But here are example of roots/turbodiesel engine, 7 psi at idle.

A guy in Australia put a supercharger on his. I think it was a magna charger. Search "supercharged duramax" Here is one of the links: http://www.dieselplace.com/forum/sho...harged+duramax

So this is going to feed trucks bottom end.

I would be very careful as the block isn't going to like you for very long if you pump it up much more! Good luck!

Three stages of compression is going to mean a ton of boost. Be prepared for blown head gaskets and as Steve said other potential motor issues. IMO you'd be better ditching one of the chargers.

Eaton is supposed to be used only when turbos dont make boost. I must do some kind of wastegate/other system so compressed air can pass eaton when turbos lit.
Same system is used in that video I link upper. I was today looking that engine. Hes old roots/turbo worked very well, this new twin turbo/roots is still waiting for installation in car.

I got 2 Superchargers on mine now, both Centrifugals. I was originally going to do the Twin Screw Whipple I have in the shed but I dont think it would be as controllable as the centrifugals but would be good to see somebody do it.

I try to get parts ready so I can begin build this in month or two.
Here is my new small charger, with old GT40 to compare.
Holset hx pro52/55 hybrid with billet compressor.
