Aaah, the good o'l "torque vs horsepower" .. Would work just fine if you had a suiting gearbox, the engine itself could take the forces involved and the engine would last forever when running at 13 000 rpm most of the time :-)

Chris have already confirmed that it won't be a 2-stroke: http://snowmobiles.yamahablogs.ca/2009/ ... /#comments As to what it could be, hmm, perhaps a souped up 3 cylinder version as their top model instead of a fourbanger. Apex chassis gone and replaced with a slightly changed Nytro...

Laban 09 Nytro XTX , can barely handle -7 C.

Yamaha needs to loose some weight on every part of the sled. Front-end, chassis, rear skid... Just compare the weight savings for the Timbersled skid: http://www.timbersled.com/MtnTamer.htm FX MTN: 38 lbs XP: 15 lbs You'll save 8lbs on the brackets alone which deserves some kind...

The 4 cylinder is only ~8-10lbs heavier then the Nytro engine if i'm not mistaken. The difference between the Apex and the old Vector engine is even smaller, only a couple of lbs. And the new Ski Doo 3 cylinder fourstroke is heavier then the Apex engine. It weighs in at 125.4 lbs if i remember...

I wonder if they should't have moved the MTX to 162" now that they have the XTX.

211 000 SEK/year which is around 35 000 $/year, or just below 3000$/month. Then we have a minimum of around 25-30% tax on that so perhaps 2250$/month after taxes.

Just looked at the 09 Prices in Canada thread so i thought that i'd share some information on the Swedish prices. Nothing new i guess but still worth mentioning. The 09 prices aren't available yet afaik so i'll take the prices on the 08 instead. Apex Warrior GT 40th: 152.900,00 SEK = ~25 000$...

Couldn't agree more. I'd like a two-up XTX with the extra seat removable. That doesn't weigh a ton like the Venture. More of a 90% one-up, 10% two-up slead.

Sure, but why not on sleds too ? There's definitely a market for 200+hp sleds, that's for sure.

Where exactly did you set that ?

I think that 144 is the way to go. It's exactly the type of sled that i want. I don't ride in the mountains but still like to have a sled that can handle the powder better. Trails are somewhat important and the 6 degree angle back of the skid should be a great solution for that. I hope they...

I'm with the people that wants to keep the seating position of the Apex. Could perhaps be a little bit more rider-forward but not much.

The Apex, Phazer ? Broad powerband is not necessarily lots of hp at low rpm's you know. I doubt it. i'd say that it was the opposite. Though there are of course some differences in the suspension, track and so forth that makes things a bit difficult to compare. How long do you think it...

You are wrong. Think about it, what happens with the rpm of the engine when you go out in the powder and hit full throttle ? As Alatalo said, the CVT would adjust itself to where you get the most hp.

Ok, now we're getting somewhere even though the discussion isn't about hp vs torque anymore. Anyway, does a high-revving & low-torque engine necessarily have a narrow powerband ? Why is is that a high-revving/low-torque engine like the Phazer does rather well from the start but has a weak...

I think we need to make things simpler, two yes/no questions: Do you think that the formula to calculate hp/torque is correct ? If the answer is yes then do you agree that 120hp@12000 rpm with a gear reduction to 8500 rpm = same torque as a 120HP@8500rpm engine ? We're talking about...

No, i proved exactly the opposite. The 12000 rpm engine will of course make 74 lbs at the clutch since the hp is the same and rpm at the clutch are the same because of the gear reduction. Again, hp always stays the same, torque is changed. I added the torque at the engine just for good measure...

Can we agree on the fact the no matter how you change your gearing(up/down) , the hp will stay the same but the torque will change ? I hope that we can cause you cannot magically gain or loose hp (disregarding the frictional losses here) by changing the gearing. The formula to calculate HP...

I kinda like the fourbanger sound myself. Doesn't mean that i think they should put a 4cyl motor in the snocross sled though. You need to balance the nr of cylinders depending on the hp you want. I'm thinking that what Yamaha is doing today is pretty optimal afa weight/hp goes: 500cc twin...
