Cool Paxton!

Although not as effective a remedy for getting cool air into an R2 Avanti’s supercharger as the ‘up front’ air intake (as used on R3 models)….. The 1964 change to an air filter housing with an inlet facing up toward the hood with the air filter elements sealed inside the canister was (in my opinion) a much improved setup as compared to the 1963 arrangement… Thoughts on this?

That sounds like an interesting solution, make an air box seal against the hood when closed, and suck air from the boundary layer. Insert a NACA duct in the hood so air gets directed into the air box. An alternative might be to make that air box seal against a hole in the inner fender.

Almost anything is better than what R2 ultimately got; that poor thing is just sucking radiated heat from the exhaust manifold. Smokey Yunick might have made something work there though; he sure delved into the hot vapor engine.

Exactly!
