Looks good Duke. Do you have a temperature gauge for the intercooler fluid system to evaluate the performance of the new configuration?

Nope - I have a IAT sensor that will hopefully show me cooler temps.
I would like to eventually have one though. I am thinking a Shawn D type switch so I can check temps on a gauge between engine and intercooler coolant temps. Thats for another day.

There won't be any performance gain on anything other than severe duty like a road course.

Its a hell of a lot better than one 5.5" X 11" HE which is what I was running before.
I feel much better with the three HEers installed now. I have increased the HE fluid cooling capability from the s2 kit by 100%. S2 kit came with two 5.5" X 11" HEers. I installed them and another 11 X 11 HE which is the same size as the two together that were supplied in the s2 kit. That seems to me to be 100% more HE and thus 100% more cooling capability. Not to mention 100% more coolant available filled in the new HE vs just the two + what is in the additional hose. I am sure there will be a performance increase in the cooling of the IC coolant.
Yet another "think to do" out of the way.

Duke again defies physics with his butt dyno.

I ain't doing squat with broken engine and trans mounts. A guy on a bicycle is faster that my car right now.

Where did this guy get you "black" alum.? Do you have your own brake? I was going to have a hvac guy make mine from heating duct sheets and have it powder coated, but yours looks damn clean.

He had rolls of it that he was going to use on an interior of a drag car. It looks to be a powder coat finish that has protective plastic that you peal off when all of the cutting is finished.
Brake? No, don't think so. The one 90 degree bend I made was on my woodworking bench vise.
Thanks for the complement. I mainly just got lucky. Once I did pull off the plastic, there was a 1" scratch right in the middle of the cover

UPDATE -
Running with 300% more HE capacity has really been nice.
My last two data logs have shown IAT temps in the low 100s F. I even noticed that under full boost the IAT initally drops and then will creap up a few degrees after the pull.
I have increased my timing to what other FI M30s are running and no pinging is audible.
I am very happy with the mod.
