Here ya go doo guys and gals. A 600 4 stroke that gets 29 m.p.g. for 2011...

Good information. Good Video

[mspease]

One major point that should be noted before you watch the video. The sled has 60 HP! That will be a very small market.

True, how many h.p. is the 600 E-Tek?? I would think aftermarket would get this to 70-80 h.p. pretty easy and still have really good mileage. Plus 4 stroke longevity. At least we know where doo is going now. Look at the first Yammy 4 strokes and where they are now. And I would say from what I have heard about the 1200 4-tek that doo is way ahead compaired to where Yammy was is 01....

I doubt very much if there are any aftermarket companies that will be able to improve E-Tek performance by 20%. It is a very complicated, very sophisticated system best left alone. The aftermarket companies simply do not have the tech to even start modifying an E-Tech. Also, Yammi first put their R1 based 4 stroke in the RX1 in 2003, not 01. Since then they have added fuel injection and a lighter crank in 2006. For 2011 they are re-doing the fuel injection system. They still have the cross-plane R1 engine waiting in the wings. They have not been standing still. The 1200 'Doo motor is a welcome addition although it is not in the same league as the Yammi 4 banger unless it is turbo'd. They ALL have room for improvement but as time goes on things have become so complicated that soon the aftermarket companies will be supplying only things like skis and studs and clothing.

don't forget that in 03 when yammi introduced the 4 strokes mpg was a major focal point of the new lineup. I know this because I watched all the hype and even bought one, it was part of the sales pitch and rightfully so. In 03 we had a new 145 hp 4 stroke sleds weighing in at around 600 lbs. Friggin thing was a rocket and a cadillac all in one. Now some 8 years later we see etech with same sales pitch promoting incredible mpg, and oil consumption. I am agreeing it is awesome to see what they have done. Some things to note here, doo is over 100 lbs lighter and still a 2 stroke. Yami and doo very different, both awesome in their own way. Don't forget, if your in the throttle your gonna see both sleds suck it down. My buddy has a ete and loves it, I rode it and love it. It does very well on fuel but he is not a johny rocket. When I babied my rx1 it did awesome, People could not believe I could get the mileage with the performance.

Point is, doo did a great job with the etek but it's gonna take some time to get real numbers from one side of the grandpa ride to the jonny rocket ride, right now hype is a big factor. It may sound like Iam sceptical of doo with the etek but not true. Just pointing out the natural hype that comes along with new tech. Is it good on gas, **** yea and I want one! But when your off trail and the hammer is down and thrill is the main factor, I personally and not very concerned with MPG. Do you realize how you would have to ride to get 29 mpg?

[indy_500]

even thought it's only got 60 hp, i don't think it's a bad idea. sure it's not that fast but 29 mpg! (this is coming from a teenager)

[samc]

29 mpg is not bad at 60 hp.......

[formula5]

I was going to look at the Video again, but they removed it...

[indy_500]

put a clutch kit on it and gear it down, 60 hp nuff for me if i'm gettin 29 mpg

[polarisrider1]

Most the Iron we rode in the 90'S only had 60hp.

[Skylar]

Until you get to that long straight stretch of cornfield, and you want to see what she will do. The Phazer is a 80 HP machine, and it runs real hard up to 65 or so, then it tapers off pretty fast.

[bigsteve89]

the 600 etek is a great powerplant. a team im on had one on a dyno two days ago and it still got 116 hp. and its still getting great fuel mileage.

[formula5]

I think the old phaser a 488 fan was 58hp. It moved pretty good.

[big_motor_guy]

dont think the 29mpg would be realistic if you geared down but it could get to 50 mph like no other, that's good, i guess.

I disagree. The automotive aftermarket has mods for new cars as soon as they hit the showroom. There are brilliant engineers in the aftermarket business, and I think it will be easy to mod future sleds. For most systems, all you should need is a remap of the electronic control systems, and you get instant power. That is the direction we are headed in. OEM's are conservative on the side of reliability. I am sure there is lots more power in all the new sleds just waiting to be found. It will be even less expensive to mod a modern sled because you won't need as many physical changes to acheive results.

[bigsteve89]

and i disagree about whether or not they will b able to come up with much of an aftermarket for the eteks, its a 6 dimensional fuel map and nearly impossible to tune without working from a stock dealership, weve been trying to contact all the major aftermarket companies because we want to try and get the etek to run off of ethanol and noone has anything even in development that can handle the level of computations that the etek does

[bearrider]

Look back in one of the 1980's Snow Goer mags and they did a MPG test on a closed course with several sleds. An Arctic Cat (Jag 270 free air?)got 42 mpg, and Cat even had an advertisement on it in later isssues. They did the test speeds at 20,25,30 and 35 mph. Heck, a Polaris Indy 400 got around 38 mpg at, I think, 35 mph. Wish I would have kept the mag with the article so I could review it and try and find out how they tuned them to get those fantastic milage figures.

Bingo.

Yes the automotive companies have a ton of aftermarket hop up mods but then agian there are a lot more vehicles out there than sleds creating a lot more demand. Your not going to get that kind of engineering and market out of snowmobiles. Will there be stuff available in the future for the upcoming new stuff? Yes. But I highly doubt you will find anybody spending time and money to develop something for a 60hp four stroke sled. It kinda goes with the old saying "you can put makeup on a pig but it's still a pig". If you want power your not going to buy this sled then start trying to make it fast.

Personally as my back gets older, I would like to see a 60 hp sled weigh in at 250 lbs. This is the only equation that the makers have paid little attention to. This solves problems with high insurance rates and fuel economy, and a bunch of things because we are still building battle ship chassis which are heavy.

When you look at what they have done to put motorized machines on the moon, 40 years ago, we have room for improvement and still get the rush from a throttle squeeze. We have barely touched the engineer "light" department.

When they do...all these behemoth machines will be sitting in museums.

[xcr440]

My dad got 41+mpg on his 1970 Polaris TX 400 (436 Fuji Motor) at the St. Paul Winter Carnival Gas Mileage contest they used to have years ago.

Made the cover of Snowgoer (I think, I can double check when I see it hanging on his office wall this weekend) magazine for it back then.

[xcr440]

And you can see by the stats on this page, MPG USED to be a point of concern, like it is becoming again.

[lvr1000]

I'd just as soon pay twice the price for gas for 10 times the fun.

[bearrider]

It's not so much of a question of cost as it is not having to plan every leg of an outing around gas stops.
