Yeah, I'm planning to build myself a cooling system. The no-money thing is really what's keeping me away. I'm surviving on unemployment for the next month and my spare funds have gotten eaten up replacing the bad shocks on the racer and catalytic converter on the Miata.
Haven't decided about sewing a shirt vs. buying one. I do plan to build a cooler/pump system. I might sew the tubes onto the carbon-x undershirt I've got. Although, that will probably lessen the cooling capability.
I think I'm going to go for the F.A.S.T. connectors when I do. They're cheaper than Cool Shirt, and 986 Racing uses those connectors too, and I'd love to have on of their shirts.
Actually, I was thinking of taking a few design cues from how 986 racing does their coolers too. Basically, put a plastic sheet as a solid baffle into the cooler. The pump will be on one side in plain water, going through a heat exchanger coil (buy cheap at Home Despot) sitting in ice water on the other side. Although it probably won't moderate temperature as well as the nice 986 cooler, it should, at least, prevent issues with the bilge pump getting clogged with ice.
Any help I could get would be awesome.
