factory turbo

[YamahaTim]

Ok let's figure this out....I'm not bashing anything! And I never said the E tec was a bad motor, I said it was a good motor. Like Yamadog said we are messing around. And I'm sure if you come on Yamaha's web page and put that kind of crazy post what was he expecting! He knows how to type and I'm sure he can stick up for himself! Especially if he comes on here and says a 800 E Tec can out run a turbo four stroke!

All in fun, YES, but really are we suppose to agree with him and move on? If I went on Doo talk and said not one 800 would beat my Turbo Viper, don't you think they would come up with some smart #*$&@ comments? I don't need anyone to stick up for me! I'm a grown #*$&@ man and I put up a post like that, then I guess I have to except other people's comments!

Some people could take his comment and consider that bashing!

I don't bash other sled or say mines the fastest. But that comment was false!

I also didn't buy a turbo to race! I love the 600 class motor and made it into a lot more! Don't worry about how I spend my money! I have it so I can spend it! I could very easy buy an 800 and have that 160ish hp. But I didn't. Would I ever heck ya. But I would never claim that it's faster that a four stroke turbo! Unless I had some pretty bad #*$&@ mods! I'm not picking on no one nor have I ever! To me with that comment he is kind of asking for a augment as far as I'm concerned!

I have to agree a Turbo 4 stroke should beat a fairly stock 800 e-tec or any other 800 for that matter.

Tim, where do you get the Rush 800 beating an e-tec 800 though? The Poo is rather under powered in the 800 class comparing it to the Doo or the Cat. I have talked with several Rush 800 owners and while they all like the ride and 0-80 mph performance everyone seems to agree they have poor top end against the other two 800's or an Apex for that matter.

Well I suppose I should have made myself clear...sorry my bad! I have friends with both sleds. And pretty much every time they race the 800 pro r wins, but it in more of a shorter distance. Like 660 feet or so. Yes when we are going higher speeds the 800 E Tec does pull on the 800 rush. Who knows about the 800 H.O. That Polaris is going to be running for 2015. They are underpowered, but have a crazy good launch, that get them ahead of the E Tec. But in a longer run the E Tec will run it down and pass. It's weird cause with my Nytro I would out of a dig out launch the 800 E Tec, but not the rush 800. And I had a 144. Both the E tec and the 800 rush had small tracks. The rush would pull on me and I would pull on the E Tec. Now around 45-50 I would pass the Rush and continue to pull on both of them. On them runs were around a mile or so. Then the E Tec would pull on the Rush, but would not catch me. I would beat both sleds in that distance. I was topping out around 113-114 mph. But the Nytro had every bolt on you could get except a muffler. Which would only give me another 3 hp. For 5-700 dollars I figured I'll stick with my stock one. Which was quiet.

Well I just happen to have one now and 3 over the last 3 yrs and have 2 buddies with 800 etecs and unless they are running thicker handle bar grips that is not letting the throttle go to WOT they cannot beat me and I get more than a sled length on them about 1/4 of the time (in approximately 660 ft). most times it is a dead heat but the uncoupled suspension of the rush 136" switchback loads much better and sometimes I pull the skis to hard and have to let out of the throttle to straighten out. Mine is stock with no clutching just a can. We have never raced accross a full lake because it has always been too rough to run WOT the whole way. I know they have a bit more top end but get them in the tight and twisties and again no problem for the rush.

As far as the other 800's I assume you are including the Arctic Cat 800 which is not even in the same class. 4 wks ago I was hitting 102 on the flambou flowage in about 2' of snow on top of the ice and another buddy on his 2014 A/C 8000 snopro with 780 miles on it would not get over 75 mph. Then I pulled out the VIPER and destroyed him!!

75 mph on the Cat? Seems to me something wasn't right with that one. As for the Poo 800 getting the launch I know with their snow cross machines they have worked very hard at getting them to squirt out of the gate with their ignition. Maybe they have passed some of that on to the consumer sleds. It sounds like the new Axys has been touted to be even better with this subject. Time will tell.

my 2014 M8 came VERY low geared. 75 mph yes.

Let me clear su=omething up on the Cat snopro 8000 it was only on the lake with 2' of snow on it that it sucked the top end out of it. When we were on the rail grade (groomed trail 4 lanes wide) he was seeing 104 mph which was the same as my rush. It does seem that the skid does not like to run fast when in a lot of snow. Or it may even be the skis / drag the pro r in deeper stuff seems to rock back and pretty much carry the skis right on the surface. We did swap sleds and I did feel a lot more nose weight in his when riding in te deeper stuff. On the hard pack trails the steering was as light as the Pro.

I wouldn't be so quick to dismiss the 1200. Everything I've read suggest the only place it looses out to the 800 is the top end. everywhere, the two are close enough that the difference between a good set-up and an OK set-up will swap the lead. I am of the belief that Doo is holding back the 1200 to get more people on their money making 800.

Could be true, but I have raced them as well with the Nytro, but I was modded and he was just clutched. So not real fair. He also had studs. But not really a race from start to top end speed. And American snowmobiler not that they are always right, but the stock Viper beat the 1200 all the way to 1000 feet and 1/4 mile time, but not speed. The 1200 really made up some speed from 1000 feet to 1/4 mile. Still lost in time and that's what counts. But it seemed to really pick up from a 1000 feet. So I would like to see top speed. The videos I watch I have yet to really see it win vs. really anything.

No factory turbo on a Yamaha and any 4 stroke that will hang with a 800 e-tech will be way to heavy.

Ok, am I reading this correctly, your saying no turbo Viper or any turbo four stoke would beat a 800 E Tec?

Because if I'm reading that correct I have to laugh!!

Because you have no clue. I smoked a 800 e tec, and he had a pipe and can y pipe and PCV. And from take off, or from 30mph and 40mph and from a dig again I smoked him. He didn't give any excuses he said, well Tim your sled hauls #*$&@ and he was very upset. Because they told him he would be the fastest on the snow. Wow did he get a kick in the #*$&@ after those races. And it was not even really close! So maybe you should do a little checking yourself.

The Viper is really not that heavy and with a turbo it is very fast! Man even my Nytro with pretty much every bolt on I could get was faster than a 800 E Tec and I was only maybe 20 hp over stock. The E tec might be a great motor, but is prett much the slowest 800 out right now. Compared to the 800 cat and the 800 rush. Although very close. All three 800's are simply out classed in a race vs. a Turbo Viper. PLAIN and SIMPLE!

Sorry guys but what Im saying is a 4 stroke that will make 800 e-tec comparible power would be to heavy like a 1100 turbo or a viper with the added weight of a turbo. I meant nothing about how fast but strictly weight vs handling.

 

[Yamadog]

That may be so but 230 hp in a sled that is only 60 lbs pounds heavier than one with 160 hp there is still no comparison in the speed. Some of us that added turbos shed that extra weight in just the muffler and several other things!
