To update this thread I decided why stop with the CAR'S cooling system? How about move the human cooling system to the back as well? In my last car I took out the AC in search of full weight reduction but that is too much of a compromise if I'm not racing for money. Anyway the compressor, condenser, filter drier, piping, not to mention the whole blower / evaporator unit can all be moved to the back. This involves gutting some of the dash as well as the engine bay. At this point it probably makes the most sense to run the AC electrically. Unfortunately that is a tall order for our stock alternator but a ram-air turbine can add the necessary power on demand when the car is moving. The stock alternator can run the AC by itself in low power mode when the RAT is not spinning.
edit: stock alternator is 180 amps, damn! It should be possible to run a meaningful cooling system off that even after subtracting demand from everything else.
I'm still thinking about the charging system. It isn't too good stock, with a very heavy generator sitting far forward and relatively high up. Any suggestions are welcome.
Anyway back on planet earth I've been doing a little more research on hoses. Some people run aluminum pipe, which may end up being what I'll do, but in the meantime I have found some sexy braided hoses:

Advantages are they look good, which is not a total throwaway since they will come up to be seen in the trunk / engine bay. Doesn't corrode either but the Al shouldn't be too bad with the right coolant. Only available with stainless NPT connectors from that vendor.
Anyone know about some sicker hoses than these, or have a vendor to recommend? I think 1" id feed and return is probably realistic.
