The 08 does not have any more power than the 09, however the 09 will outperform an 08 due to the factory upgrades. The 09 is lighter [22 lbs. if i remember right] has the tapered tunnel, and the powerclaw track [which is probably the single biggest improvement]. The 09 also has the electronic reverse which mandated a different Diamond Drive [alot lighter]. The weight of the Diamond drive is on the front of the sled which is a problem for the 1000 as they are a little nose heavy. They have the same power and if the 08 has the updates done to it they also have the same fuel map.
