Here's your baseline runs. When you get your head redone be sure to tell them its for a fuel injected motor and port acordingly.

Thanks for posting.........Talking to Steve this last weekend........plan on an updated dyno sheet around the beginning of April. Looks like a small Dyno War taking place in the near future.

The 40hp run the guy almost launched the quad into wall as he didn't have it strapped down correctly and the entire quad shifted to the right.

Its to bad you didnt get the tach lead hooked up. Going by wheel speed doesnt make for very good dyno comparison charts and you dont get any torque readings. Be sure and keep the same exact gearing next time you dyno so as not to skew results . Good luck. Any more news on the mystery ported head? Got any pics after its cleaned.

my updated dyno run is going to be delayed. Race season is getting too close and i need my quad back together. Maxpower is still going to be working on some stuff along with web-cams. Looks like I would have that set-up back first week in april, but decided I didn't want to be tuning the week before a race and have no seat time.

Looks like a break in the race action in may so I'll look at doing it then. sorry guys.

Looks like me and C27 will have my quad back on the dyno Saturday morning. Plan on doing a couple runs to compare old ATK piston to new, and then tune it for Klotz race fuel to show any differences with the fuel. Maybe we can squeze 48hp out of a stock motor. :0
