OK, I got everything put together.. here's my initial assessment..
It's hard for me to compare EGT's since my 5x012 injectors packed it in last week.. Took it for a quick drive though with my 4x013 injectors, might have to loosen the star wheel a little, has no fuel plate anyhow... it's dark so I can't see what the smoke is like.
It does spool a little slower but I haven't tuned the controller yet, it definitely flows a LOT more air on the hot side.. probably close to double! I do a lot of tooling around in 4th gear (NV5600) on the dirt roads, seems like 10psi boost at 1400 is no problem to get, 1800 I think I can get any amount I want.. 5th gear rolling into it at 2000 it lights the tires and hits 3K pretty damn fast..., EGT's were 1200F
Next Monday I'll have a couple ton behind me in the trailer and I can see how that does.
As for the sound, definitely a lot louder, but it's more of a whoosh than a whine, at least at the power levels I've been asking of it on the dirt.
It took HOURS of machining to do it, I had no specs or anything and a manual lathe, so it was a lot of small cuts and test fitting!
Here's a vid of machining the hot side
