On cool mornings or just after I set out on the road, it runs very well but on hot days and after running it begins to sag. I suspect this is due to charge heating, despite the air intake hanging out the hood in the slipstream. I need to add a manifold temp gauge to confirm this (drilled/tapped a hole for one) but I have to believe ADI is needed. Also, is a fixed jet system adequate? I plan on piecing together a system from CoolingMist unless I hear to the contrary. Does anyone know what the ADI system looked like on the WW2 aircraft engines? Wonder if it was a simple on/off or if it was demand metered.

Not sure about the ADI or CoolingMist systems, but that Roots blower is definitely not helping your air temps. If the boost is higher than 5 psi I think the temps are too high due to blower efficiency.
