I received mine and the performance wheel kit, both are well designed and put togeather as I was skeptical at first. They have made the install easy to follow and the kits are for the most part all put togeather already. The intake kit looks sweet, sounds sweet and I would say from going from stock set up to the kit you are geting Mid and top end pull through, My RPMS jumped up about 400 - 500 RPM's after I installed it.
As for the wheel kit, they are not the plastic wheels, they are very stout rubber as I have seen used on grass drag sleds so I would imagine they will hold up alot better than the marginal snow wheels that seem to flex. the shaft is light weigh and was well machined.

Ya come on guys spend your money so i can see what i want to spend mine on too lol i would like to add both stages of this ram air kit and the techlusion tfi box plus with the excell exhaust should be the icing on the cake.. Now my dealer has picked up the excell to sell he saids its the best exhaust he has ever used,and he had the white knuckle exhaust he sold the last few years with good luck too,but he did say the white knuckle was a little to loud,but he had stated that the excell was just so good soundind but not so loud everyone is looking for you,but the surprise was when he had two identical rtxs all clutched stock both ran the same,until he installed the excell,wow is what he said no comparison now,its modded rtx everywhere from bottom all the way to top and beyond,he was blown away from the performance,and i told him its only 2 hp on top diff,he said ya but it feels like way more... 
when u ride a sled with a loud exhaust,it gets in your head that it is an animal,when in reality its just a few more ponies and not much of a difference......i may be interested in this ram air kit

thanks for the feed back. rideblueforever, how long did it take you to install ram air kit and how many mile do you have on you sled??? 
Here is something that you should read before installing the hood scoop.
Generating air-flow by itself also does not require much energy.
Example: A radiator fan uses relatively little electrical energy, and can flow 400 to 700 CFM. However, just blowing air on something does not generate pressure, unless it there is both high air-flow rate AND air-speed. This is proven when one looks at how a "RAM-AIR" scoop works. A "RAM-AIR scoop only develops .07psi at 80 MPH, but can develop .38psi when the car is traveling at 180 MPH with a perfectly efficient ram-air scoop like the ones that are seen on Indy cars or above the hood of drag cars.
At 80mph the ram generates .07 not .7 psi which is next to nothing for increase. Mind you if it can take away the negative air pressure (vacuum) out of the air box while running WOT you will see a gain as it is a bit over atmospheric pressure and not in a vacuum state.

about the only gain you are getting is a louder engine and colder air to the throttle bodys..
The viper had RAM AIR.. and several magazines proved that it didnt work.. (didnt add any HP)
I am very sceptical as to if it really works... I would have to see dyno numbers to believe it!

And if it does work, its only when your sled at near top speed.
ram air wont work until very high speeds
i posted a article here 2 times about it
i think a sled would have to go over 130MPH before it would get any extra horsepower
i can't find the article any more though

Forced Air Induction?
The Real Scoop on Yamaha Ram Air
TECH
Larry A. Kaduce
ith the imminent season approaching rapidly, the online sled forums are really starting to buzz, including our own Max Forum. Looking at the various posts, the thread that jumps out the most is the messages on Yamaha’s new Forced Air Induction system, as offered on the new 2002 SX Viper. There is apparently a lot of confusion as to what the forced air inductions system is, how it is designed, and how it actually works.
We’re not sure if this started with a misinformed dealer, or if the sledders themselves were just overly anxious to order this new machine that they didn’t really pay attention to the specs. Hey, we all know how that goes! But to call the system a fake is just pure ignorance and a plea for more information. Well OK, you got it!
When introduced to the SX Viper last January, the included tech session showed us how this system was designed, as well as all the features and benefits. The system seen on a dealer’s showroom floor is exactly the same system introduced to the media last winter – nothing changed.
The benefits of forced-air induction are increased engine power by forcing the air to the airbox. From the beginning, this was never meant to be a direct induction INTO the airbox. C’mon, get real! Have you ever tried to run your sled without the airbox on a cold day with snowdust in the air? The first time you do, you’ll know it; that sled will squeak so tight so fast, you’ll wonder what happened. Even a filter or foam protection would be useless, as it would be plugged instantly.
Yamaha designed a way to force air to the airbox without the risk of also injecting snow. The only way to do this is to pressurize the underhood area with forced air. The vents along the headlight draw in air - under higher speeds – on each side of the airbox to create this pressure. The pressurized air is forced into the top of the airbox through a slot in the hood behind the headlight. If the forced air includes snowdust, ice chunks, dust or debris, it cannot make the sharp turn needed to go straight up and then back down again to enter the airbox. The air is then forced down into the bottom of the belly pan, which pressurizes the hood with clean air. This forced air system acts somewhat as a filtration system as the air entering the airbox is pre-cleaned by the pressure.
In addition, the float bowls of the carbs are vented into the airbox. This reduces the pressure during a holeshot, which enriches the fuel mixture and prevents bogging. Under higher speeds the pressure rises, creating the force. Pressurized air increases the fuel flow and adds horsepower and reduces the jetting sensitivity. Yamaha tests confirm that the pressure can add approximately 3HP under the right circumstances. However, during a strong crosswind, the forced air system would have little to no effect as the air would be drawn across the vents as well as into the vents. These are good days for a Swiss Miss anyway. Does this clear things up a bit?
After riding the SX Viper for 2 days and several hundred miles, the Maximum Sled team can attest as to how the system works. The engine was crisp and powerful in all conditions, which is no wonder why Yamaha will have a huge demand for this machine. No matter if you’re a solo touring rider or like to hot dog on the trails, the SX Viper is one of the few machines that has appealed to such a broad range of riders. If you ordered one, we’re sure you’ll be happy. We can’t wait for ours! <original article>
The bottom line is that Yamaha’s Forced Air Induction System is not a Turbo or a Blower, but rather an elaborate system that works and is produced exactly as it was intended.
Now that we got rid of the hot air under the hood, it’s time to do some pre-cleaning of all the hot air in the forums.

It took me about 2 hours to install the ram air and cold air kit. I don't see what the viper air induction has to do with what this kit is. Your not comparing apples to apples here and this motor is going to respond totally different with Ram Air.
As for some of the other posts that said yamaha would do this if it worked, well how about the exhaust, clutching, ski's, plugs and on and on you could say that about all the aftermarket stuff.
As for some of the other questions, you cannot DYNO ram air, but I would definitely say it pulls harder through the mid and top than what it did as my sled was completly stock and there was a noticeable change from stock ride prior to ram air kit. I would also think it will improve as I only put on a few miles and once the EFI calabrates for the additional air mixture the performace will improve.
My two cents is it's worth the money, I have no complaints

Ram air is ram air,,, it doesnt matter what you put it on... I believe i talked to someone about the 05 R1 motorcycle that uses RAM AIR and they all said it makes no added HP..
In a controlled enviroment like a dyno room you could find the effects of a ram air system,, but using a high powered fan..

Bottom line is if it feels like its pulling better than it properbly is,and you know how it went speed wise before do some tests and see if in fact it runs faster top end,and if it raised your top rpms out and it dosent overev past 11,000 i think you may run faster,please keep us posted or pm me with your results,as i am interested,thanks PeteRideblueforever said:

Ram air does work. They don't spend the ching on putting it on their race bikes for nothing. Is it a reasonable application for a sled though? That I would like to find out. And really the only good test for this is to test it in a controlled environment on the same sled on the same day with and without.
