I would like to know the power band of this engine as well is it smooth or on/ off ? I have a jammin .21 i put in my buggy , it's a great engine but just hits too hard. I am now running it in the truggy & it's good but need an engine for the buggy. I would be the first one running this engine at my local track, everyone thinks you need a 500 dollar os speed but i think it's overkill. So is it a better buggy engine or truggy engine ?
