I know vertdef, we work together, have not ridden with him yet, but I know he knows what he is talking about. I do not doubt the results he gave at the beginning of this thread..................... HOWEVER, I seriously doubt the XP's he rode with are set up as they should be. I'm not saying modded, but SET-UP.
If you think about it, the race he quoted is probably purdy close to being true, after all, its a turbo that holds power at elevation better than a 2 stroke, and its a flat str8 race in minimal snow depths. OK, round 1 to the FST.
Now, Let's get together with someone who knows how to tune & set-up the XP and run them in a snow climb hill drag, deep snow highmark, and dockin in the trees .......... Rounds 2, 3 & 4 will go the XP methinks.
Vertdef and I are trying to get together and ride and we will post the results, I was wanting to make the ride with Matt & Kevin of amsnow to see what the foofarah is all about with the M8, but I am down sick as a dog now.
I rode with an exceptionally running 09 M8 153 800 SLP setup, pipe & can on my Afton ride this past week, while it gave a good showing, it was no match for my stock 09 163 w/ HPS can.
