I use a SCHWITZER S300 with .83 exh a/r

here is the map




we did 490rwhp and 404torq @ 23psi on this turbo

 

here is what it looks like

the wheels are just almost the same spec as a T51.
I can wait till I turn the wick up and bring it up to 2bar
if a few weeks

 

What manifold is that?

 

HKS cast for FC

 

any new info for this thread?

 

I had a turbo from the 7.3l powerstroke a year or so ago, but could find little info on it cause Garrett doesn't release specs in a timely manner, and the engine was brand new. I ditched the idea of trying to fit this on my FD cause it looked like a big project with questionable results.

 

Have used the GT42 truck yurbo on my partners FD and a friends RX2.72 AR com cover with 1.22 AR exhaust
makes about 320hp at wheels at 1bar.
