Hi Brad,

I'm done with performance upgrades so I haven't looked into turbo housings. Remember I have the older WH1E turbo (the mother of the HX40). Only way I'll change turbos or housing is if mine fails. I'm back into maintainance mode now.

Most of the distance I have run since the mods was with 2-4 psi max boost. I've only moved twice short distances with the boost back, and temps were about 70, and grades were minor. I'll have to get back to you when we start traveling a bit more as to gauge boost and egt reports.

The higher flow muffler should drop egt a bit. 2 degrees more timing I had rolled in is reported to lower egt, but raise cylinder head temps, so I'll have to watch egt close to protect the pistons and head. More timing is also reported to raise power yet also raise mpg. I'll have to refuel before tracking results on mpg as I ran a good bit of miles with no / very low boost.

Have you looked into the turbine housing that Banks installs as part of their stinger system set up? I assume that it does not give more boost as you are getting the same boost as me now. I wonder if it helps spool the turbo up sooner and or quicker.

What kind of exhaust temps are you seeing at 32 lbs of boost during a long climb and also what was the ambient temp?

Good luck Dan.

With the relocated boost sensor, and the relocated diesel performance elbow fitting/line to the waste gate, I am seeing a soild 34-35 psi boost. On a 2 mile 4-5 %grade I stayed at 34 psi (on purpose) and max egt was 1050 - 1075, ambient temp about 70.

I'll watch egts on long grades and as ambient temps get higher.

Sounds great Dan. Since you stayed at a moderate size on the fuel plate your EGT may stay cool. I will be curious what it does as the weather warms. Good info.
