I put 800 miles on a 155 X3 last year and was in no way sold on it! Rode sugar, super deep pow, heavy pow, and spring snow, and I dont think I ever once thought, wow this track is awesome, or even better than the 5.1 in any way, besides down hill braking. I never had cooling issues either (had to run scratchers on the trails and hard pack, no different than a stocker tho!) but the track just didnt really have much of a fun factor, just kinda tractored around everywhere trenching like a SOB. Back on 5.1 this year, just seems better all around. Who knows, new chassis, different track, different motor, maybe it will work better on the Axys, but if I snowcheck it will be the 2.6 for me. Ive read the phrase "poor mans turbo" way to many times, to even try to compare the X3 to a turbo in any way is just a wet dream.... But again like I said who knows, maybe a 3"er will work great on the Axys, time will tell.
