R&D. How many miles do you have on your boosted Nytro? I'm just wondering how well the Nytro engine is doing under boost. My friend just had his engine rebuilt in his stock 2012 PRO RMK. It had just under 1500 miles. My turbo Nytro has 2600 miles with 1400 miles under 11 lbs of boost. My supercharged Nytro has 2900 miles with 1700 miles under the same boosted. Let's hear your story.
How many mile do you have on your boosted nytro?
- Thread starter Sharp
- Start date
09 nytro mtx boosted w/ mcx 180 kit at 700 miles, ran that upgrade until 1,900 miles then upgraded to the 240 mcx. Now showing 4,400 miles, I'm at sea level running pump gas, no mix. But I do run additives in both my oil and fuel fwiw.

2010 Nytro Mcx 190 running about 7.5lbs boost with 8300 trouble free km. I run premium fuel with a little av gas.
1,000,000 .......or so it seems.
Seriously though, I have 16,000k on an MCX 270 that I still ride from time to time. Pump Fuel 17lbs of boost @ 6,000'
I don't really worry about mileage on a 4 stroke engine. Its the other chassis stuff that needs more attention.
Happy Boosting.

ps...........I know I have accumulated over 50,000k of Boosted 4 Stroke Mountain sledding since 2003 RX1.........nothing major as far as failures go.

we have seen..
We have seen several with over 10,000km's on them, all boosted and running strong. Best engines on the snow by far!
Just going through the drive and jackshaft bearings on Jimmy's last week, he has 10,125km's on his Nytro, Boosted since day one, just thought he should do some preventative maintinance by replacing the bearings, ..and they were still feeling fine.
16-17 lbs of boost and the engine will last seemingly forever. Stay on top of drive chain adjustments and your clutchs, do your maintinance homework and it will outlast any sled on the market!!
Cheers

Mileage?
Boosted at 1200miles. I have 3058miles now. Running 270MCX 17psi pump fuel. No issues.

8000km mcx 270 running av fuel, basic maintenance.
Header failure, fuel filter plugged, bellow failures, bov replaced, wire on alt sensor rubbed through, had a short in aux power plug and poped fuel pump fuse, valve cover gasket was leaking, charge tube had almost rubbed through, modified stock tunnel bc it sucks.
It has never let me down and I would call most of the above just maintenance issues. I put a new chain and belt on every year. Go through the bearings every 2 years or so depends on how many miles.
Best sled I have ever owned.
