I have been more than happy with our HM Turbo's kit with water to air intercooler. The colder charge temps have to be worth power, and if you ride in deep BC pow, then you will be on the throttle more, which does build heat.
I also like the fact you don't have a separate oil pump or coolant lines to the turbo.
In packed snow it is heads up with a 240 hp MCX Nytro running only 8 lbs boost as opposed to the Nytro at 14.
If your interested, go see Jordan at VP fuels in Calgary and check the kit out. I know he has one in stock. We can install it if you like. Boost-It has a retail shop now and only works only turbo sleds, and our labour rate is way less than your going to get in the city. We are only 1 1/2 hrs from Calgary.
