16v 2.0l engine, N/A stats??

[marc_scirocco@sympatico.ca (Marc Scirocco Québec)]

1HP = 750 Watts
P=EI so 750 Watts / 13.8 Volts = 54 Amps
My Scirocco draws that (measured) with the headlights on, heater on, stereo
on, motor running at 2000.

Scirocco draws how much at WOT? 20 amps? (not running big lights and the big
stereo of course)

So, 20 Amps * 13.8 Volts = 276 Watts, around 300 Watts

Make the alternator not 100% efficient, so say, you need an extra 40% for
mechanical, and electrical resistance.

300 Watts * 1.40 = 420 Watts.

Maybee half of one horsepower. Let's be generous, 1 HP saved.

Anybody electrical engineer can confirm my thinking?

Cheers.

guarantee it doesn't take 10 hp, probably not even 5.  I'd guess maximum of
3.

And how do you measure that? Any data to prove this?

Cheers.

> So when you jam the throttle, the alternator cuts out freeing 5-10 hp?

Yes, precisely.
