Let me start off by saying that, that is an innovative approach to heat shielding.
That being said. I think you will find that the area that needs shielding the most is the decking around the carb/efi area. the exhaust curls around the edge of the motor and rises up as it meets the other side and crosses over. This puts the thinner tray and the first part of the rear section of the clip in harms way. You can see from my pics those areas are the ones that bake the paint and causes small to large bubbles in the paint if there is A. no insulation or B. not enough insulation. You can see from the third pic there is no bubbling of the paint.This is at the rear of the exhaust vent. I have absolutely no insulation in that area
Mine is from not enough. and actually got this way with a previous paint job. The fiberglass is weakened(my idea) and the heat is transferred more easily and will affect the second paint job. BTW I did the second paint job and the clip at repaint was taken down to the fiberglass, and was very smooth at that time. Actually had to take it down that far because I had stripes on the first job and they had a tendency to show through if any was left at all. That paint job was done by a professional and there was no unevenness in the transition to the stripes.
Take a look at how Chuck andRyan did their insulation and you will see some innovation with how they accomplished theirs. The amount of space between the exhaust and the fiberglass gets pretty close in that area.
Ryan and I added accessory fans in the front of the engine bay to try and help with the movement of air across this area. It didn't help mine much. I used to turn those fans on when I was in stop and go traffic, and it still blistered.
You may find yourself at the end of a ride when you turn the engine off the off delay fans that we added will help move the heat along, but I
always opened the rear clip to help dissipate the heat. It's too bad we can't do that at every stop light.:idea:
One last note. I built a deflector panel that attaches to the rear tray area and when the clip is closed it goes between the exhaust and the EFI. The goal is to get as cool an air flow to the injectors as possible.The angle I came up with was > than 45. Its just a thin piece of aluminum that is the width of the opening.
I have been toying for some time now with building a Lexan housing for the injectors and filters.
