I am in the process of modifying my 2010 Nytro Rtx SE. Im installing oft 144 extention with a 1 3/4" track and the 42in concept a-arms and other small mods. I ride trails in ny and some open fields. Im thinking about MPI turbo or a supercharger What would you do if you were me.

Try FPP not to far from you, Little Valley ny.
How much boost do you want to make now and possibly later?how much into the engine do you want to get?

Ulmer turbo for a nytro is awesome, bigger tank,etc. That is what I would buy if I had a nytro.
The heat under the fuel tank is what I think about. The supercharger wont make the power a turbo will but maybe more trail friendly? That said they will always see boost with a supercharger and a turbo sled can cruise with very little boost on the trail. Either way i would call Allen Ulmer for his recommandations and service after the sale.

turbo or supercharger
I am looking to have around 180hp with the option of increasing hp. I want to install and ride. I dont want to have to tune and do alot of upkeep. I dont really want to get into the motor I just want to bolt on and go. I want to be able to break the track loose at anytime.

Of that's the case a small turbo set from Ulmer or a stage one set low from mpi sounds like the trick. With the stage one you have future potential to hit that 11lb range, but more then likely will have it around seven-eight lbs for an extra boost without all the engine work.... every boost option has particular ceiling on power before you have to do more to the engine or fuel system. Turbo has the most future potential for big power and is different at cruising speeds then a charger. A charger may be easier to take off later if you want to sell it separate from the sled. Either way I would talk to a few speed shops like Ulmer or hurricane to get their professional opions on what you want now and possibly later. Since they deal with a lot of flat land setups like yours. Good luck and let it snow.

A lot of guys really like the SC because of the low end response and the fact the OEM exhaust is unaltered, others like the turbo for the mid to top end power and fuel economy. Some of the turbo kits out there have proven to run right with an SC off the line and then walk away from it, so in the end it depends on your riding style and preference.
All the companies have good customer service and really they are all going to provide you the 180HP and will all have the option of increasing the HP, but the difference will be what it takes (the components and $$$) to get that from the base stage 1 kit because you are limited on boost level with the stock fuel system and on pump gas the stock engine because of compression. The MPI SC comes with an upgraded fuel system so you can run up to 11 psi boost with better fuel, as with the Ulmer and FPP stage 1 turbo kits that is an additional option.
Each kit’s design will have it’s own highlights and draw backs, as well, so you really should do your due diligence on researching each.
Although the Ulmer kit is very good, there have been complaints of inconsistent tuning and response gremlins. That might have something to due with the log style cast exhaust manifold or related thermal issues, or both, as it typically has to run a higher boost level to make the same HP as others. The highlights are Ulmer uses the Power Commander PC controller that is very expandable and programmable, and can utilize the stock muffler or most any aftermarket of your choice. It also is rather beefy and won't have to worry about exhaust donuts.
The Full Power Performance is a multiple award winning low elevation trail kit and has shown to be more efficient making more power with less boost, but as long as you are riding on snow… Because it uses heat exchanger type snow intercoolers in the tunnel instead of a cored air intercooler under the hood, it potentially could have less ability to cool the intake charge during extended WOT running at full boost on a hyfax eating bare lake, hard pack, asphalt, etc (where there is little or no snow dust or water getting kicked up) then other kits so it is definitely a purpose built trail kit. You also have to remove the rear suspension to install them so that gets more involved. The highlights are the FPP kit already includes a boost gauge, blow-off valve, clutch kit, gear, and stainless trail muffler so there are no added costs after the fact to complete it. Also like the Ulmer kit with a stock muffler, it's very stealth using the stock rear exhaust outlet location and cover.
I am not that familiar with the Push or MPI turbo kits, but I don’t recall if they have an intercooler and hence probably not really trail friendly kits. More for mountain riding.
MCXpress has a 180 kit that is popular with the mountain guys that also uses a single tunnel pre-cooler, similar to the FPP, but it's limited to 180HP and isn't very stealthy as it is exposed at the rear and can't use the stock rear cover.
Powderlites has a very popular Nytro kit, too but will likely require your own flatland clutch tuning as it's an elevation kit, or get a clutch kit from a low elevation dealer. It also can't be used with the stock rear cover so it's exposed like the MCX.
The SC kits have had a bad rep for poor fuel economy, which some will argue if that can now be overcome with by-pass valve tuning, etc. They also have to run more boost to make the same HP because of the inherent inefficiencies. The highlights are you can get an MPI for 6000+ ft elevations installed by your Yamaha dealer that supposedly doesn’t void your warranty, and well... its a blower!

kits are hard to resurch
there doesnt seem to be to much info on any of these kits online from the manufacture. If I could see install instructions that would help me to decide which kit would make sense for me. From what ive seen The MPI turbo kit has its intake were the stock exhast exit is and exhast under the tunnel. I like the idea of that setup so i could have a small bag on the tunnel. What i dont like about it is that they use the same gems controller that they use with the supercharger. I like MCX's set up but i think it would be to loud and i dont want to get tickets on the trail. I havent looked to much into FPP yet I will. I guess its a good thing that there are alot of manufactures of turbos out there but they dont explain there kits very well. As with most anything if I have install instructions I can decifer which kit would layout and work for me the best. OSP supposedly makes a kit but I cant seem to find out much about it. I origionaly liked ulmers kit figured no lag with mid mount but the more I think about it I think that the heat of the turbo would be better where the sled was designed to have the muffler. thanks for the input so far. Im going to get all my mods done early this year and work on setup as sone as the snow flys. If I think the sled can handle the power I will decide whick kit to go with. This sled stock allways handled poorly and i never needed to go any faster than 85-90, with the mods I am doing i hope i either make a good off trail sled or one that can handle the extra power.

hahahahahaha Turbo all the way, but I'm crazy so who am I to tell hahahahahaha
turbo or supercharger
I found the instructions online for the mpi turbo looks good. The problem with the fPP setup is that I have the mountain heat exchanger in the tunnel where there charge tube is and i still have overheating problems with just the right conditions so I dont want to take that out.
