Ok Guys...here is going to be an interesting race. My dad has a 1990 polaris indy 650 tripple. I have this friend who wants to race him who has a 2003 ski-doo rev 600 h.o
Who do you think is going to win? Tracks are both studded./snofan/../images/users/fassell_man/1990650.jpg

The Rev will win hands down. It has practically over 30 HP more than the 650 and is ligher.

The 650 will probably take it on the top end, If the 650 is pipped and tuned it should blow the rev away. If the 650 is stock its not gonna be able to stay close enough in the low/midrange to catch it on the top unless your going like 2 miles. I'm not scared by rev's with my pipped 650, they have no topend and the old 650 is all top end just need some runway to catch it. Also odds are good for the ski-doo to stick a piston midrun. Even a stock 650 is only down about 10h.p, (95hp 01 motor,108hp 02-03motor) vs.118, piped 650 is 125-130 well tuned. Put some chisel tooth studs in the 650 and race him on ice, then you got a chance hehe.

Its not the year its the series, i believe it went 89-90 were 01 motors 95 h.p, 92-96 were 02 and 03 respectively 108h.p. had different porting for the h.p. increase. You can identify the series by the number stamped on the heads. I just looked it up and snow tech only squeezed 115h.p. out of the 600 h.o, H.O. talk about a marketing term, which puts it slightly behind even the polaris 600, and staring at the F6 snow flap. I haven't seen a Doo twin thats had an impressive top end and the revs ergos. make the top end even worse. Rev would hand me my butt on the trail, but the lake is still good for even the old 650. Stock for stock the rev 600 should win though, from an 80 punch I think the 650 if it runs good would slowly creep by and keep pulling, the p85 clutch and button secondary are much better suited for top end than the TRA.

why would polaris use there dyno to confirm that the doo makes more power. There is nothing H.O. about the doo 600, its 2nd or 3rd in the 600 twin class, Arctic Cat should be calling there engines "super high output", if doo's gonna tag theres as H.O. I'd put my 650 up against a stock doo 600, my 650 isn't quite stock though. I already know the outcome too[:D]

indytripple there is a difference in the rotax series III 600 and 600 ho motor. The HO motor uses a 700 crank and base, Thus giving the HO quite a bit more power. Basically the 600 HO is a 700 motor with modified 600 cylinders. Not to bash anyone but I still say the REV will win. Ive worked on and ridden alot of stock and modified 650 sleds and they just dont impress me at all.
