My dealer did my turbo install in 9 hours with the Helex, front bumper, tunnel bag, afr and boost gauge's I provided for $900 total. Said they could do a mpi turbo in 7-8 normally.

I was at arctic man a large snow machine event 15,000 or so. A lot of us viper turbo sled got together to go for a few rides and there is a big difference between the guys that intercooler and shimmed there sleds vs guys on the same psi that did are running clock motor and no cooler. Had two...

Ok great. Seems like the big changes to the engine, head studs and head gaskets go in around 10psi? I have had a friend running his nytro for 5 years 3000 mi with 8-9psi on just a fuel pump upgrade to his push turbo and its a beast on pump gas.

At what psi does the set up require an intercooler? I have been running 6psi all year 600mi no issues good afr 11.5 wot. Wanting to put on the fuel pump and ulmer clutch and go to 8psi. This is all at 3000-7000ft

Is the sale on Mountian kits as well? Does it have instructions on running more psi than the standard 5/6psi.

Nick. Don't the fingers give you a better trail traction? The 3" seems like they were trying to save weight and don't care about the on trail manners. So far I,m really happy with my 2.6 PCI, does everything well.

Seems like an AFR of 12.5 is pushing it alittle. Have you had any issues at 8#? I have only dared to run 6# at low elevation and never any long pulls. I show 11.4-11.6 max.

I used a flat head screw driver covered with a pice of card board and put pressure on the side of the bolt (to hold it from turning) folcruming off of the triangle hole to turn the nut with a gear wrench. Don't use anything to squish the threads

I,m running 5.5lbs at 2000ft with 11.4-11.6 AFR WOT.

You guys know there is an update kit to your mpi turbo kit. Came out a few weeks ago. http://www.snowest.com/forum/showthread.php?p=3787520#post3787520

Thanks for the help guys. Here are my pics to help anyone else. On the right side of sled take off the rubber boot as shown. Pull out plastic push pins. Turn steering to left to expose 17mm nut in triangle cutout. Tighten nut and your good to go. At end of Handel bars I went from 2-1/2"...

Good timing. After just 200miles my steering has at lease two inches of play before any movement. It even seemed to lock or bind up when at full turn. I will check the above mentioned, thanks

Put 60 miles on today playing in the hills. Had been loosing half a quart every ride. Fixed my problem, but never had it upside down. I'm happy.

I've been buying a quart of oil every weekend for my viper, reminds me of my 2stroke days. Today my dealer called me in to put the update kit on my sled. Thought I would spread the good word. Thanks mpi for dealing with this issue. http://www.snowest.com/forum/showthr...20#post3787520

I,m running my mpi spring order kit ((no intercooler)) at 4psi wot around 8700rpm. Still playing it light till I get more miles. 3000ft elevation. Seeing readings of 11.7 afr. The sled is running great and is running 45mph track speed up the hills with decent powder.. I,m worried the afr is too...

This is the set up I used and it works and looks great. The only thing I didn't like was the boost gauge in this picture, I already changed out the boost gauge to a 0-15 psi for a larger more accurate reading, the -30/+20 is too small to read while riding. The AEM AFR is perfect. The mount from...

I'm less than impressed with my sleds ability to start. I have the turbo and it is a beast to start past zero. On our first trip to summit we loaded the sleds up in the morning -5f, half way to summit we stopped for fuel and I started my sled on the trailer because the temp was near -10f and I...

For alittle precaution I started mine off with a 1/1 blend of race gas 101 and our super 90 octane and I could not get the sled to fire once temps went into the negatives. So I've backed way down to a 10% race fuel blend and it fires right up at -10f now. I,m only running stock boost 4.5-5 I was...

I went with the aem afr guage it runs the newer Bosch sensor that requires no tuning. My boost guage is an Autometer -30/+20. Don't like it because it's so small of a sweep in the guage so I orderd the 0-15 from autometer. My sleds low boost 6psi and the sleds don't pull vacume so you don't need...
