<VV> High Capacity Alternators

[Ron Hinz]

Has anyone ever seen an alternator on a Corvair pull anything like 100 amps? 
I'm skeptical if anyone ever has because the only instrumented test that 
I've ever heard of was run on an Ultravan by the Ultravan club and their 
result was that with a properly adjusted belt, 50 amps was about all you 
were ever going to get before the belt starts slipping.  That limitation 
comes from the 1/4 wrap on the pulley and it's a design limitation.  People 
can claim anything but it's the measured numbers that are meaningful.

If you had a Corvair powered UltraVan, you would understand the need for
a 140 amp alternator.  The frig and ice maker alone draw 60 amps.
