Still fixing things. Received the ZyBar coating and applied it to both exhaust manifolds. It was very runny but sprayed out fine. I'm unsure how effective it will be at reducing the heat. They claim a 90% reduction in radiated heat, but that might be for a thicker coat than I was able to get out of the 4 oz. can I bought. At $80, it was some pretty expensive snake oil. If it doesn't flake off under operating conditions, I'll consider it a win.
The exhaust system revision is progressing nicely. I reinstalled the H-pipe I'd removed long ago. I found that moving it back 3" let it clear the shifter cable and still have adequate spacing between it and the E-Stopp. I was short one 90 deg. tubing bend but it should be here today. Once it arrives, I'll be able to connect the manifold flanges. I'm hoping the combination of the cast iron manifolds and the H-pipe will reduce the noise level a bit. Not to mention lowering the underhood temps.
I also installed a Flex-A-Lite aux trans cooler. I didn't want it in front of the radiator which is probably where it would work best, so I located it under the splash pan. There's a factory opening in the pan right above it which should direct at least some air from the high pressure area across the fins. Once I get back on the road, I'll connect the laptop to see if it's working. Typically, the trans has been running about 15 degrees hotter than the radiator. If that narrows down a bit, I'll assume it's the cooler.
