I have heard some rumors that you actually lose a bit of hp with the longevity kit. PMS what can you tell me about your hp figures with this kit. Other than that ive heard all good things about it.
You definately do NOT lose a bit of HP with the Fix Kit. Unfortunately, the are a few copies of the original Fix Kit out there now and may be muddying up the rumor game.
As a former transmission dyno operator, I do not put much stock into anyones dyno sheet. In my experience, when the owner of your company is dishonest and tells you to make the sheet say something the product can't say on it's own, it makes you a very skeptical person with dyno reports.
The Fix Kit from MTNTK adds reliability, longevity, and performance. It was the first aftermarket kit to come out and has also been the most successful. I can tell you that in the sled's I have installed and tuned after installing Fix Kit's, there is
at least 5-7 horsepower but the real deal feel is the huge increase in torque which is most noticeable in the deep snow. Each of these sleds have needed another 2-3 gram's in clutch weights. You put a stocker with the same track, track length, and suspension next to the Fix Kit'd sled and you will see the difference quick. It's almost a stock 600-800 difference in comparison when riding in 3 feet plus.
The Fix Kit will also compliment an aftermarket head and SLP pipe much more than a stock 800 CFI. Another noticeable glaring fact in my testing is the fueling requirements of the Fix KIt motor is less fuel is actually. EGT's and A/F confirm much less fuel is needed.
I also installed a Fix Kit in my '12 Assault. At 355 miles.
I was very leary of installing aftermarket piston's in my motor and my customers. I played that game back in the 90's. I had always endorsed OEM piston's in stock bore motors prior to 2010.
I didn't really believe there was a real problem back then. Unfortunately, when I decided to tear down my 09 Dragon 800 with 300 miles for nothing more than boredom, I was shocked to see a hairline crack in the PTO cylinder skirt.
This motor had been maintained, warmed up, extra oil, etc. better than any sled I ever owned. Half of those miles were from my wife who stayed on trails. A Power Commander 5 had been installed after the first ride due to the horrible low-mid, tip-in throttle hesitation. The sled had the 2010 motor update installed before taking delivery.
