'10 M8 Will it get derated befor Production?

[offtrail]

Back when Polaris first came out with their dragon 800 they were preaching it had 155 horse. Dynotech came back with a 147 ish number. This pre m8 has a dynoed160 plus. My question is with all the EPA requirements are they gonna be able to meet emissions and keep the Horsepower up there? Or are we gonna get a derated over hyped 800 like Poo did to their customers? What do you guys think?

M8

They should be ok. They just copied D&D shim kit to get the HP. I did the kit this year on my M8/ 2009, works extremely well. D&D dyno sheet shows the hp.

It is not a shim kit. Y-pipe and pipe are different. Lighter crank, different mapping. They might have included some other things but that is the jist of it.

whole new motor to my understanding the pistons, exhaust valves, cylinders, crank, mapping and exhaust are all different from the 09's.

By no means is the 2010 just a shim kit, the whole engine is different. Higher compression and much better porting just for starters.

The difference here is that Cat is claiming 155-160 and Dynotech is saying 163.

Quite a few changes, but the 2009 model had a lot of pent up HP that could be unleashed easily.

I don't think it is so far fetched to get another 12-15 HP out of this motor. It has different mapping, porting, y pipe, pipe, can, pistons, and crank.

Yes, spoken like someone who really knows what he is talking about

Maybe just a little more than a shim kit.....Don't ya think?

Much of the weight change came from the 4.3 pounds lighter weight crankshaft. That means the engine spins more quickly, which accounts for the noticeable increase in acceleration. You’ll find the engine was fitted with new pistons, cylinders, head and revised exhaust valve reed petals. The electronic fuel injection was revamped and remapped and, of course, the exhaust was redone to accommodate the upgrades.

Im sure you just overlooked these things right?

Maybe I am drinking the green Kool-Aid, but if cat claims a HP I believe it.
They have been proven conservative on the Z1 Turbo, M8, M1000 where as Poo and Doo exaggerate.

I have at least seen the pre-production dyno graph, and regardless if it hits 160 HP or not I love the steady climb in HP that it has. This does not seem at all like a peaky motor which hits 160 and looks like Mt. Everest on the graph. I think its going to be an animal, probably in the 157-160 HP range

2010 M8,s

OK I have put about 75- 100 miles on the 2010 and I have not found any one who was not impressed. I normally only ride a turbo but the new sleds are very impressive. They have m1000 Grunt Ported M8 Responsiveness. I love the sled We drag raced all day and the only thing that beat them was the turbo's. Then get it in the steep and deep they are fun Well we could not find deep but steep wet heavy snow they just keep pulling.So hear it is wanna a turbo buy a hold over want a stock out of the box sled that rips get in to your dealer and snow check one.

They sound like the real deal. Just so they hold together. And from what I've read it sounds like they will!
