[DeTomaso] Electric Water Pumps, The 21st Century of Water Circulation

Sat Apr 13 09:50:13 EDT 2013

Janne,

That alternator works for a race car at best. For street driving the
output is too low for general use.

I'd rather like to try this good looking mechanical water pump which has
integrated permanent magnet alternator.

Don't know if windsor pump could be adopted to cleveland though...
