Results with WI on a V-8 w/Roots blower?

[stusanders]

Anyone here using WI with a Roots blower? I have a 5.7L Chevy V-8 with a Weiand supercharger, thinking seriously about adding WI but would like to get some opinions and hopefully results before going to the trouble. I just finished tuning the set up and have noticed a strong correlation between air temps and apparent power production. 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.
