Went to the guy who is building my banshee today and got to see one of his banshee's that has the new cub cylinders run on pump gas and it dynoed at 108hp, he just converted it to alcohol and should dyno around 125 he thinks. Just an amazing engine, my 2 cents.
His web site is http://mccoysperformance.com
If you want power talk to these guys, ask for Nate tell em Tyler Schofield sent u.
