How well do these work? I'm gonna be using an underdrive crank pulley on my next build so I can keep my A/C and power steering happy. I was thinking an overdriven water pump pulley would make up the cooling losses from the crank pulley. This is going into a high revving 427, cooling will definitely be important. Let's assume a regular run of the mill aluminum rad with a flex fan, or possibly an electric fan, on a stock pump. Will this be a beneficial piece or will I be pissing money to the wind? Not ruling out an electric water pump either, just wanted to explore the cheap easy option first.
