freind of mine has an 04 or 05 blair morgan 800ho.out of the hole he takes me(i can not get my 99 srx to hook up at all!!!)on a long run i will catch him and we are both even right up to 200 kph on the dream meter!!we have had the same results many times last winter. we are the same weight(200lbs) around the same hp(140ish) but his rev is about 50lbs lighter than my srx 700.not bad if i do say so myself. i think if i could get my sled to hook up so i could get the hole shot he would never catch me!!! btw, he is pissed with the results seeing how he paid almost $14,000.00 (canadian) for his sled ,and i paid $5000.00 two years ago. unless you have triple pipes on your viper, the 800 ho will smoke you every time.
