Great suggestions guys. Thanks. I'm intersted in Ian's link. I'll post if I find anything else out. I might check the price on that, even though I don't know if it would fit under the hood. Thanks again!
$805 +SH 120 lbs 8kw size 19"x13"x9" Needs to turn at 3600 rpm
The htz and volt output is related directly to the rpm of the generator. A govener like Alan said would be the ticket. Good luck fitting the gen under the hood.
