This fall I sent my cylinders off my 11 800 etec for a little of Dave'a magic. I would have went an 872 but Dave said he couldn't make enough power out of the 11 etec to make it worth the money so I went with the porting, head cut and coolant manifold. So far I have 150 miles on this package and I'm really impressed. I have a little more tuning to do but this package flat out works. Yesterday I had a chance to compare with a 872r 154 and a stock 163 xm and I was very impressed with how it stacked up. Yesterday we were lucky to hit a nice 2-3 feet of fresh. This amount of snow put the 154 872 at a bit of a disadvantage. My sled could usually eek out a high mark on the 872 in the fresh. In a track you could see the 872 would make more speed up the hill. Track length was the difference there. If the 872 was running a 163 I'm pretty sure I would have got spanked. Comparing to a stock xm my sled would out climb it and make better ground speed up the hill. Pretty pumped how I stacked up with those 2 sleds. I really can't wait until I have the clutching dialed in. I was pulling down on some climbs and it was causing me to loose some track speed. Once the clutching is spot on this thing is going to be a beast! Thanks Dave!
