Here is another artical for anyone interested. I doubt it comes up as a link. The last one I did didn't work out. Just exactly which way do I have to hold my mouth when I paste it on here? LOL!

It's that "new" math doncha know anything??? GEEEEZ! Get with the program!!!!! LOL!

EFI is a wonderful thing, and having EFI on my Arctic Cat Pantera snowmobile is one of my favorite features of the machine. No doubt EFI would be attractive to some people and a selling point for others.

However... An atv is subject to rigors which a snowmobile never sees. Water, mud and travelling in normally inaccesable areas. The ATV operting environment is more "carburetor friendly". Most people on this forum can fix a carb but not an EFI system falure. There is also the expense factor, with the throttle position sensors, cpu, air temperature sensor, injectors, O2 sensors etc. Can you imagine sinking the computer in mud? All of these components are linked electronically, which is another weak link in the durability equation.

Torque? The vast majority of torque producing engines have a longer stroke than bore size. The popular over-square bore is used for high RPM engine applications. I can see where your confusion comes in because in the world of power there is no replacement for displacement.

Anyway its all conjecture and pipe dreams... isn't it? Do you think Polaris is scared of Kawasaki?
(they should be)

Do you think Arctic Cat will every drop the Massey Ferguson image that they have and insert a little ZR500 or Thundercat technology?

 

Hey Thor

I see you own a pantera 580efi. I have been having some problems with the front engine mount and hope that you have an answer. E-mail me on the above link so that we can talk without putting irrelavent messages on the atv connection. Thanks in advance.

 

Thor,
i agree that the conditions that a ATV goes in can be very harsh. but i do think that a EFI would work. Look at the Rubicon, it has a computer for the Tranny and its seems reliable.

true that a EFI computer in a atv wouldent be as easy to design as a sled, but with carefull engineering it can be done. the computer would have to be very high and tightly sealed.
as well as all of the sensors.

they will have no trouble making high HP 4 strokers for sled look at street bikes. take a GSXR 1100 motor slap it in a sled that would be something, they are developing them for the PARKS. which is why they are slow, the parks do not want fast and noisy. I am sure that we have the technology to build a 4 stroke motor that would sream we can make motor cycles do 180 stock out of the showroom, we can make a sled go 100 + with a 4 stroker. it is the future wether we like it or not.

 

I have to agree that I think infection would work. However I would rather be...oh,,,,,I'm sorry, that's neither here - nor there is it? LOL!

Anyhow, you already have sensors all over. Low oil pressure (4 stroke), low oil level (2 stroke), coolant temp for the fan. I don't see that adding an EGT sensor, Intake temp/ambiant pressure sensors in the airbox would be much diff. They may get swamped ocasionally, but I don't see that being to their demise. As far as the 'putor. Put it up high with all the other wiring. But even at that, I don't see the putor getting swamped killing it. Maybe just the connections. Just like the voltage reg on my sled, after they are done making all internall connections, they just filled it with a somewhat clear plastic/wax brew. The connection is the only thing that is out in the elements. AND even if they don't infect them, there will be more and more sensors anyhow in competition to make the lighter/ more powerfull (or just to keep up with) machine than the competition.

They are currently doing timing mapping on the newer sleds using most all of this info right now. All they need to do is put on the throttle body now. This is how they get SOOOO much power out of those sled motors.

I agree I for one am not going to rebuild / trouble shoot an infection problem in the bush. However, if the putor doing the timing takes a dump, I'm out of business anyhow. So, may as well look into infection to get more power/economy without fretting over the jetting constantly.

They do not have to reinvent the wheel. Detroits been doing in for 15 years. Also, most of the manufactures are doing it in outboards and jet skis already.

I hope to buy a new Scrambler 700 w/infection in a few years. And I don't see it costing any more, or sacrafising reliability. But what the heck is reliability anyhow? We are talking Polaris right?

JUST KIDDING! Keep your tuk on eh!

 

>>>>but i do think that a EFI would work. Look at the Rubicon...<<<<

Yes it would work but, would it be feasible? Cost effective?

All snowmobile computers are insulated from ground, what would water dunking do to ground?

There is no doubt that "they could do it", but would you be willing to pay extra for it? All of those parts come from vendors and the cost ads up.

Consider this. If this was the apocolypse and you were Mad Max, would you be driving a Honda 300 fourtrax or a Polaris?

 

Snowride,

I tried to send you an e-mail but the "net nanny" here at work will not allow it. hehehe
