After 2 years and the lethargic performance at 6300***8217; altitude, I fixed my problem.. she makes 2-3 psi boost and 1-1 drive pressure. Really woke the tractor up with no fuel changes.

It***8217;s a Garrett GT1543 with a billet compressor I made on a 5 axis mill.

I was gonna ask, where is the air filter? Need to spool it up to about 25 or 30 psi.....:D

Bravo! Put me on the list for a kit when you have it ready to ship.

I’m not sure a kit would be feasible, might load yours up and bring it my way!!! Lol Really wasn’t hard, worst part was getting the angle right on the turbo to clear hood plus keep oil drain as close to vertical as humanly possible.

About the same size (diameter) of the turbochargers on my M9's. Of course my M9's are charge air cooled as well.

Something I need to do is put a boost gauge on them. I bet it's more than 1 or 2 psi spooled up. I know my diesel pickup makes 20-20 spooled up, has a boost gauge.

the goal was basic altitude compensation, in theory it should make exact rated power as it would at sea level being i dont touch the fuel. that being said, A diesel with forced induction will always be more efficient than a NA counter part. My pickup on the other hand actually makes less than half the boost pressure than stock, ported head, hogged out intake and S480 turbo make things wayyyyy more efficient, efficient to the point of making a reliable 640hp at 37psi vs 550hp with stock VGT turbo at 70 psi.
