[QUOTE="Monkeypants, post: 40684, member: 2708"] The horsepower numbers on their website appear to be rounded off BHP numbers rather than RWHP numbers. This makes sense as manufacturers have been doing it that way for eons. By way of comparison, Terry Prince told me that his Bonneville hotrod has dynod 142 rwhp also on methanol. This equates to about 160 bhp assuming 10 to15% drive train loss, really pushing it for 1350cc and the original cases from the bike he bought at age 17. Steve Hamels results might be more indiciative of what is possible for a road engine, over 100 rwhp, 998 cc on pump gas. I'm not sure that any of these creations would make long term high mileage road engines, but a lot is learned when the envelope is pushed! Glen [/QUOTE]
