New 800 C-Tec?

[Snirtdawg]

Unless you race on lakes, go off trail extensively or ride in the mountains, an 800 just sucks 25% more fuel and you get nothing out of it.[/QUOTE]

In my experience with both 600cc and 800cc engines, the 600cc engines actually use more gas as your deeper into the throttle to maintain the same speeds.

I have ridden with more 800 Doo's than I can count... I always use 25 to 40% less fuel. We are usually within 25 to 50 yards of each other on the trails.

I think the 800 just spins its track more and is over torqued in most situations.

I always said a 600 is plenty and I would never spend the money or need an 800.....until I found a good deal on my current sled which just so happened to have an 800. I'd be hard pressed to go back now. I know a 600 will go faster on your average trail than I would typically ride anyway, but it's all about having fun and the power of the 800 is more fun. JMO

My experience is the 600s that ride with me generally use the same or slightly more fuel than me.

I have considered switching to an 800... It depends on the winter too. When we had the really deep snow in 2013-2014, I spent a ton of time off-trail and I was always wanting more power. The last two winters I hardly went off trail, it's just crusty crap as far north as Grand Marais.

Way too much hassle with other 800's running out of fuel or hunting for fuel.

I average about 16 mpg all day, every day. It rarely varies. That gives me 160 miles of riding without worrying about fuel. Most 800's seem to average around 12 mpg. That's 40 miles less per tank.

There might be something wrong with them then. It's almost impossible to do this otherwise.

So does that mean a 1000 would do better than an 800? Would a 1200 do better than a 1000? You could go all day with this logic.

I maintain them myself. There is nothing wrong with them.

Please explain to me how it is impossible.

I definitely get the range factor, my 800 has a small tank to begin with and it just makes me more aware of where i need to stop. I will admit that a 600 sled is a darn good sled for about everything. I do ride a 800 and enjoy a the mid range and upper acceleration. I top out around 100 and PD keeps going and yes I ride with him for 4 days every year....hes a speed guy and loves those long sweeping corners and straight aways. Its all in what you like.

The amount of fuel required to push the cylinder down is 25% more. The best fuel economy is when your engine is right near the bogging point as the computer will throttle back fuel if the engine isn't able to rev up enough to match the throttle input. The 800 is going to be ready to receive the extra shot of fuel in the same speed you are running at. The worst fuel economy is when you are using more throttle than necessary. The key to fuel economy is to be at the perfect balance of power delivered to power required. The 600 is in that sweet spot much easier, since the 119 HP is much closer to what you really need to maintain speed.

I thought we would be getting some ride reports on the Ctec-2 800? Not even a word from Chad?

 

[POLARISDAN]

I said, racing on a lake or riding in the mountains.

What good is 113 mph for most people? You can hardly exceed 60 mph on the trails unless it's a perfect straight away. My sled does 94 mph as it is.

You are not going 90+ mph around any corner. You are probably not going 60 mph around many corners.

maybe i misunderstood, but i thought u said an 800 was ONLY needed in the mountains or on a lake..

uh, at nite i bend the turns on 3 between 85 and 90 as my nite riding buddies will attest..not 90 degree turns, winding bends..and for most people u are correct, but i felt u painted a large broad stroke there..and on any str8 away..forgetabboutit

LOL, your post is exactly why you are wrong.

"since 119 hp is much closer to what you really need to maintain speed"
Your sled is not making 119 hp at partial throttle. If your max hp is 119, you need to be WOT to make 119. Your throttle plates must be fully open to make 119. Since you need as much air as possible to make that 119, you need that fuel as well.
My sled CAN make 119 hp at partial throttle. And does not need throttle plates wide open.

You cannot "bog" a CVT transmissioned vehicle.

Sweeping corners, sure... I can nearly hit 90 on my sled too. It's a matter of physics though. Unless you have the ski width, you are going to hit a tree and get splattered at the speeds a 600 Etec can accomplish. The 800 is good for racing, mountains and deep powder. If you aren't doing any of the 3, it's just a waste of fuel and money.

I end up passing half the 800r's I see on the trails as it is. They buy them because their buddy said a 600 is a chick sled and that's just feeding into a dumb stereotype.

omg dude..not sure where ur coming UP with your thought process..ive had both and would NEVER ride a 600 again..Now if they made a 1000 2 stroke axys..count me in

also not sure what ur talking about wider tracks and hitting trees..i run a stock sled..have never hit a tree nor came close..once again a wide brush

I understand your points, and agree with your posts 100%. 600 is ALL you need for WI trail riding, MI might be a tad different. That said, I own an 800, but only because it was the right deal at the time. I prefer the 6.
And if I said an 800 takes the same fuel as a 600, both ridden by same weight driver and same speed - I'd say I was delusional. There's too many variables to actually measure the difference, but there is one.

I am not saying that a larger CC engine will always get better mpg than a smaller cc engine. But the opposite is also true that a smaller CC engine will not always get better mpg.

Like stated, Jonger was painting with a very broad brush. There are many many factors in determining mpg.

Look up some dyno sheets and see how much fuel engines are using at a specific rpm and power. Its obvious that a 800 can cruise at a lower rpm than a 600, while both are using the same hp.

Here is some technical reading if you are interested. Its older, but will always still apply in current designs of all 2 stroke engines.

BTW, I own a 800 because I wanted it. Not because of any mpg expectations, or even top speed expectations. In fact I have never "topped it out" and I have 3k miles on it. I have probably had it to 100 mph less than 5 times.

I wanted it, so I bought it.

If the 800 got better fuel economy, I would have bought it. I have over 15,000 miles of experience on a Rev XP chassis and ridden with numerous other Rev XP 800's and 10/10 times, the 800 sucked down about 25 to 40% more fuel. If the 800 got better fuel economy, I'd be rolling one. Even Ski Doo lists the 800 as less fuel efficient.

That article keeps referencing ports... our sleds are not port injected.

Well its obvious then, that the design of those doo 800s were not as efficient as the doo 600s.
But I will say, my bud has a doo 800, that has been worked over to a 860cc engine and he generally gets 17 mpg. Its a P-tek and XP chassis.

BTW, all 2 stroke sleds have ports. Every single 2 stroke sled, ever built by every single manufacturer. But since EFI the manufacturers can be more precise when and how much is injected.

and not bucuz ur buddies said a 600 is a CHICK sled

 

[snobuilder]

uh my friend..u r loopy..i max my 800 out at 113 this year..to say there is no difference between a 600 and an 800 is just plain wrong..i bend corners on 3 at the speed a 600 tops out at..no offense meant please

Woow Hoo!....that's my bestie....ain't he swell, cool, phat, bad, badassed!!#badassed....113!.....

My Damn 05 RX1 only hit 122 one time. 124....the rest of the runs, only 12000 miles on it though....it probly had more....but I guess it's an unfair comparison....the cheating RX 1 turns 11000 rpms

Where's the LIKE button. Bending turns on 3 at 90+, can you say "how long till you go splat, into tree". Lookie me - I race on the trails.

 

[snobuilder]

My 800 AXYS ran within a half gallon of my buds 800 etec and I weigh about 150 more pounds than he does. I don't think that is to bad? Plus i am the leader and I feel that takes a bit more gas!

Slimcase is typical of guys who run hard on there Polaris' along side the Doo etek owners. The truth is proved at the pumps.

No splat,....PLEASE...WE NEED EACH OTHER TO COMMENT ON, and stuff.
