I'm wondering if RTU is saying in "race form only" you don't need a radiator or maybe just a small one at that?
That actually is interesting that you could do that. RTU definitely needs to clarify their claim. I don't necessarily buy that their cooled-off intake manifold idea actually improves fuel economy.

This is why I have such mixed feelings about ethanol. But that's going to veer off into verboten territory...
