Anyone thought of putting a compound turbo on the deuce? I know they do it to newer Diesel trucks. I wonder if its worth trying on a deuce.

I've heard of using the turbo off a 5 ton to increase the boost and that helps out quite a bit. The only problem there is head gaskets. Even a stock 5 ton turbo will cause the head gaskets to fail unless things are watched very closely. I guess you could always tear the engine down and fire ring the heads, but I'm not sure if it's worth the expense.

Compounding or variable vein turbos would help keep the turbo in its efficiency range, right? Which would mean more power at lower EGT's, yes?

Ideally, yes. But we're (for the most part) dealing with a 50 year old tractor engine in a narrow RPM rangeburning anything from gasoline + 30 wt oil to 90 wt gear oil with a splash of kerosene to thin it. I understand where you're going with the coolness factor and all, but it'd probably be easier to get a new-ish 24 valve Cummins or an 8.3 ISC Cummins and twin that and shoot 20 foot flames out the stack.

not needed. you get full boost in a stock application at a very low RPM.
the point of compound turbos is to:
1. keep a turbo in it's peak eff range.
2. decrease spoolup time.
3. double the reapir bill when something goes wrong.
4. double the complexity of the entire system.
In these trucks it's not needed and not wanted. spoolup is very fast and the stock turbo is enough to blow the guts out of the motor anyway.
if you want more power turn up the fuel and WATCH the EGT's !!!
