Hopefully by now everyone knows my story. Been riding Yamahas since 2009. Turbo Nytro, Supercharged Nytro, big boost turbo Viper. Last year decided to make the transition from boosted 4 stroke to 2 stroke, and picked up 3 brand new 2017 Ski-Doo 850s. 2 SPs and 1 Summit X.
As a general rule I try NOT to do mid season major installs as I all to frequently seem to run into problems and I HATE having to rush through an install because our season is SHORT and I don't want to lose any days of riding to a sled torn apart in my garage.
My son on the other hand doesn't see things quite the same way as his father does!
So he went ahead and got himself one of the new Turbo kits from MPI a couple weeks ago and decided to bolt that sucker on his new 850 and start living the life of Boost once again.
While I also plan on installing an MPI Turbo on my 850, I am trading out my 2017 Summit X for a new 2018 Summit X with the new SHOT starter system on it, so my install, which WILL BE my normal HIGHLY DETAILED STEP BY STEP install and review, will have to wait till my new sled arrives in Late Summer or Fall. THIS post will be almost exclusively a RIDE REVIEW for those members who are sitting on the fence considering whether or not to boost their 850..
==============
The MPI Kit arrived at our house in a single large box, VERY well packed and ready to go. The kit does NOT include a printed manual, but a link to a full color PDF document on the MPI website. First thing we did was to download the PDF and PRINT IT OFF so we could have the paper manual in the garage to follow through step by step.
The installation itself was pretty darn straight forward. They estimate about 6 hours for a professional mechanic who has done this before, about 8 hours for your above average Shade-Tree snowmobile mechanic and probably 10-12 hours for your hobby enthusiast that has never torn his sled down before. We used every minute of 12 hours.
Only one specialty tool was required for this installation, and that was to crimp the fuel lines. Otherwise just normal tools for everything else.
But we did find we "wanted" a little more heat shielding tape than was included, some extra Zip-Ties, a little Loctite. Do make sure you have some replacement coolant fluid, or a CLEAN container to drain your coolant into so you can recycle it.
