Gosh, I don't want to get into a pissing match here so I hope this is just a friendly discussion. I was posting what I know to be first hand accurate information. My son and I race 1/4 mile Banshee's. In 2008 our best ET's with both quads running Banshee based motors on alcohol and no nitrous was 10.07 and 10.19.
IMO $1000.00 in private purchased parts/upgrades in a stock Banshee still can't compete with a stock 1000 Artic Cat. A really good ET from a stock port cylinder and carb Banshee with reeds and pipes is 13.40's
** This is 1/4 mile I'm talking about. Maybe that's were some of our difference of opinion is?
