The alternator will have to go on the cool side, and I will have to cut the stock WP down drastically to have enough room for the fittings. 2) I don't like the location of the WP. It's sitting right at the top of the engine so that there are pumping problems as soon as the coolant gets a little low. I bought one of Paul Lamar's remote mounted pump castings to fix that. If I could leave the alternator at the top, I would put that pump on the side and forget about it. Putting them both on the side is going to get complicated. The EWP's will solve my installation problems. Will they solve the cooling problem? I'm willing to spend a few hundred dollars to find out. If it dosen't work out, I will have to figure out how to make the RMWP (remote mechanical water pump) work. If I can't figure out how to do that, I'll go back and cobble up the stock pump. Anyway, that's my reason for trying it. Bob White -- http://www.bob-white.com N93BD - Rotary Powered BD-4 (soon)
