HP loss with axle driven Nippon-Denso alternator

[Rick Iverson]

Gents;

Rough guess, please?

[David Ferguson]

745 Watts = 1hp
50A x 12 V = 600 Watts

With that rough math, less than 1hp.

And you Sir, are the steely-eyed missile man. A wealth of knowledge, you are.

I would expect it to be about equal if the gear ratio driving the pulley is the same.

[R. Pare]

There will also be a couple percent mechanical efficiency loss, no mater how it is driven (usually about 2% for a toothed belt), along with internal efficiency losses in the alternator itself, which can also easily be 20-45%, depending on the design.

Can you switch it off for a temporary power gain?

Will still take some HP to drive it even when off

[alangbaker]

Add and electric clutch in there...

...and have something else that can fail.

Yes, most can, but it depends on the type of alternator.

RP;

A Nippon-Denso single wire modified for FC use?

I Googled same, but my research skills suck just about as bad as my math skills.
