When I moved from late model stock cars to outlaw sprint cars, I found we had fewer problems with engines overheating, largely because we ran straight methanol in the sprints where rules for the stocks required pump gasoline and methanol burns cooler than gasoline.
(Not that we actually ran straight pump gasoline in the stocks. We always added an octane booster to our fuel in the stocks. Can't recall the name of it, but we added a quart to ten gallons of gasoline. I don't know if it actually improved performance, but it gave the exhaust a distinctive aroma.)
