Turbo Nytro: What are my choices??

Lets say that I purchase a brand new 2010 FX Nytro MTX SE 153




And lets say that I decide I want to have a turbo charger installed on this that runs in the 6-8lb boost range. Just enough to compensate for altitude loss at 7,500-8,000ft, but not enough to have any real impact on longterm engine durability.

What would be the BEST choices out there??

who wants a 8psi kit? then you will want 10psi then 12 then 15............ might as well just get it over with you can always just use 1/8 to 1/4 throttle and be at 8psi!

I have had the distinct pleasure of building High Performance boats for several years. Along those years we supercharged a good number of them, and worked on even more. I know ALL TOO WELL the realities of engines that LIVE on boost. NOT INTERESTED in driving a grenade that is just waiting to blow.

My goals are rather modest, and I know that any decent turbo can always be adjusted if the need/desire comes along.

But for now, 8psi will be just fine for my needs up at Island Park with the wife and 4 kids...

And anyway, I am just thinking outloud here, still considering my options of sleds.

OK, so several of you say the MCX turbo.

And my question to all of you is WHY MCX?

What makes them "THE" one to go with.

Seems like there is a PILE of competition out there to choose from.

Are none of the others even worth considering??

No, it is not the only choice. Its a fairly poor choice IMO. Look at some other threads on here, you will find what you are looking for

Care to offer any SPECIFIC comments as to why "YOU" think that the MCX is a poor choice??

Or to point out any specific thread you think I should be reading up on this subject?

MCX, 10 #'s boost, pump gas and ride. I wouldn't limit myself to the 180 hp kit, build it right the first time, can always turn the boost down. Most always want more.

And it may well be that down the road I might want more as well. But my past experience has suggested that often time More = Less.

Less time to go riding
Less money left in my wallet
Less fun when they grenade

The #1 reason I am considering the yamaha in the first place is reliability. My time is precious and scarce, and I do NOT want to have a sled that is prone to being down.

When I ditch work for a day to hookup and go play, I need to know my sled is not going to let me down.

if youre worried about blowing up motors dont be ! Ive ran my impulse nytro on 17 pounds for around 4500 km now . I havent had a single motor issue , and i plan on putting on another 4000 km this winter . Any thing under 12 pounds isnt worth worth the time or money to me . I ve been there . Impluse makes a very nice pump gas kit this year as well that has more bang for youre buck then the mcx does IMO :beer;

Thats very nice to know.

17lbs of boost is significant for a stock motor that was NOT reworked to run forced induction!

2,796 miles of trouble free use.
Not bad at all.

mcx are fairly problem free. They also have better fuel system management. If you want full out race, id probably say alpine or impulse. But you want an turn key pump gas turbo. Cant beat mcx. And i run a alpine on my 08 vector. 15lbs all day every day.

Not interested in racing or trying to get up the steepest chute on the mountain.

With a wife and 4 kids, I just got a good solid FUN reliable sled that will let me go up into the mountains and have a good time. Something that is capable of a little bit of "Everything".

Make no mistake about it, I really enjoy riding the Ski-Doo Summits that I have rented over the past couple years, but I am SERIOUSLY concerned about service/maintenance issues on them... so I am looking at the Yamaha as a viable alternative.

It would be great if the Yami could compete on the weight issues with the Doo, but the reliability is probably more imortant to me than the extra pounds that I can just as easily take off of my own waist line.

Is this the kit some of you are suggesting?

This is the ONLY one I see on their site, and it seems a bit "beafier" than what most are talking about??

Are there any known differences in the engine from 2009 to 2010???

Yamaha has released its latest creation Nytro and of course is MCX developing a turbo kit!
The dyno test show 240 horsepower.
After one season, we can certify that both the snowmobile and the turbo kit works excellent. We have sold several hundred of turbo kits with extreme reliability.
Until the season 08-09, not much has been changed. A new blow off valve is installed on the plenum and the location of the EFI-box is changed. Even the price is the same as last year (Counted in Swedish kronor sek.)
The engine perform excellent! And show that with turbo we can produce more power than the standard engine at low 5000 rpm.

The location of the turbo is exactly right for most performance and throttle response,
we also have enough space to use a snow cooled precooler that gives even more power and ensure that we can use more boost for high performance.
We can now offer an upgrade kit to 270 hp that includes a new fuel pump and fuel pressure regulator +some more parts. The EFI box also needs to be re-mapped.
