2017 Yamaha Sidewinder Dyno Report!!!

[Ricardo]

Not to rain on anyones parade, but all that 204HP dyno run proves is that one, prototype, 998 is capable of producing 204HP. Not that the production ones that show up next fall will be the same. It wouldn't be the first time a manufacturer in this sport has provided super performing units for the magazines to report on only to detune them for production( the famous explaination" Further testing revealed issues requiring recalibration"). And we all know how easy that is to do with a turbo. And perhaps that new super ECU will take the aftermarket performance companies two years to hack into to get the boost(and HP) up? Could happen.
I sincerely hope this does not happen here, but we won't know for sure till they come out of the crates in the fall, will we?

the ecu is irrelevant a guy can toss it in the trash and put in a v pack and build his own tune. if u think the guys wont be building race maps in august before fall drag season well what can u say . if u cant by pass glen and Kelly will both have a map built and D&D and bmp will have a v pack with a close to it tune before snow fly's .
that said I still bet u wont get a reliable 320 out of that motor for very long

and even if your www hp number toss is true.... who cares?....LOL I see you came up about a 100 hp from your prediction last week of what this new motor could not do....LOL

I am very surprised people are so excited about this unproven machine. This has to be no more than a 5% niche market, and you are right, prototype is typically radically different than production. They have warranty, quality and liability to worry about. It might be $500 annually to insure this motor.

Thanks for the link Boomer. I thought they were going after the dead drag sled market. Sounds like they have some long tracks coming our way.

well the old 1 could not make a season of 660ft running 300 with just light mods who knows with a better bottom end it may. I will put a hundo on it right now it wont match what the zuk can reliably run for close to the same cash in both. it is a sweet trail set up for sure but I will put even more money on it the big boys will each run 1 but they will be winning on the twin

ezra, ...why not accept that Yamaha has stepped up when everyone was saying they are leaving snowmobiles in the rear view instead of continually struggling to throw out far fetched negative scenarios.
I am a Yamaha guy for the most part but its good to see that the Cat chassis is an improvement to the Yamaha sled lineup.
All info so far is pointing to the 998 being built from the ground up as a turbo based motor.
I have no idea of how great the zuke twin is to the .001% who buy a sled for the sole purpose of drag racing it. Who cares? Beating up on the new Yamaha motor before it even gets into a builders hands is a waste of time.

chit...if I was going to build 400 hp drag sled, the 9000 would be my choice......they is damn near giving them away!....LOL

Hey snowbuilder; Whats with the "snowblower" stuff??? Because the engine has a turbo system on it?????????? Being designed, engineered, and built as a turbo, by far much better than add on kit. Learned my lessens back in late 60's, early 70's putting "add on" turbo's on farm related engines. Had some failures due to learning curve. Many issues involved. Extra heat, as in exhaust temp, and coolant temp, valve guides as to lubrication due to increase cylinder air charge (boost), and piston, ring, and sleeve stress.

SW comes in many different packages so not offered as just the 5% straight line package which was typical in the past for big dogs. SW comes in trail & powder versions so the hp junkie in all those niches have a cure for their need for speed. I do have concerns what the insurance companies will charge for this sled?

naw,...Yamadooood has been throwin out pet names for me on here. he thinks I am someone from another website....LOL

what far fetched negative stuff am I saying? beeting up on it no just stating what I have seen 1st hand based off old one under heavy boost and what world record holders tell me about building a boosted 3 cyl . I said it will make a great trail sled did I not? I would bet a whole lot more than 1% bought the twin 9000 with the sole intention of using it 660ft at a time I know of 8 with in a 2 mi radius of my hose alone .
I am fine with the yammi deal always have been glad they did and not just drop out. I wish they would actually get back in the game but I really do not think it will happen unless they need to loose some money.

I'm not a Yamaha guy first off.
But with a turbo, rods, lower CR pistons, and studs, the old 3 cylinder can make very impressive hp, and be very reliable. Over 400hp. And close to 30lbs boost. Yes, rods might seem like a lot, but they aren't expensive and you have to lower CR anyway for boost. Yes it's not as easy or cheap as a zuke twin, but if you want real power, it's never cheap. Add a billet cylinder and it's good for over 600hp.
My bud has a Nytro mtn sled with 400+hp and has 1700 mtn miles at that hp without opening the engine since the turbo was installed.
He still has it, but his boosted Polaris 800 RMK is more fun to ride. His Polaris 800 has seen over 15lbs of boost with stock bottom end. Just Kelsey's pistons and 12.1 head. That's around 220-240hp on the Poo 800. About 1000 mtn miles since boosted. No changes since turbo installed, but engine was opened to check its health.
BTW he's a tree rider, absolutely zero lag in both sleds.

P.S. I'm not into drag racing at all, but didn't OSP beat up on the D&D boys a few years ago with the old Nytro? Maybe I'm wrong, but if I am, they were certainly right there with them.

that osp motor is a beast and a whole lot more than some rods and a pinned crank.
I don't know just know what I have seen in the past and what guys who actually make money racing theses things are saying .
again cant say it enough it will make a sweet trail sled . the drag guys I know are not thrilled

Yes, and the D&D has many extensive mods as well.

The point I was trying to say was, you don't need crazy stuff to make big HP with the Nytro. Which is what you were saying.

Idk what kind of power can be had out of the new engine, but I'm not sure how you can be sure it's going be low without big mods.

The reference was to the 204 HP hyper-motor, not the SW, and the 5% niche is no doubt overstated - more like 2.5.

I'm being told the production will be at the number I stated earlier. In fact. the prototypes I rode were didn't even have the right clutch on them thus causing them to over rev so that being said I was told they pull even harder than the protos I rode. Maybe I'll be wrong XXX007 but I don't think so Wow these threads really take off in odd directions Either way there will be a market for this sled and it will sell as my snow check numbers are proving that Thanks for putting in the articles guys. Oh yeah, EXUP valve did not come until 2011 Apex.

I hear ya Kip SW will be a huge seller for Yamaha 1st factory turbo/engine/chassis combo from Yamaha from ground up is very attractive to the masses. Congrats you will have a big year & waited along time for this!
