For starters your only gonna be able to run a 136 track as that is the longest they make, I am assuming your rmk has rail extensions to make it a 144, the only problem that will present itself to you is that 136 by 15 asphalt tracks are no longer being made by camoplast, so unless you can find a used 136x15 your gonna have to find a 136x10.5, but running a 10.5 with a stock suspension there are some modifications that need to be done on the rear arm to make it work, or you will have to spend big money on a true 136 asphalt suspension, you will also need extra wheels placed between the rails for the track to run on as the hi fax have to be removed, you also will need a set of asphalt skis that can be found used, my brother just sold a set of brand new USI asphalt ski's for $290 shipped to Canada, if you want to look at a site that has pretty much everything for asphalt racing go to:Ettenrmk said:I'm also looking into maybe getting into asphalt drag racing. I got a 98 Polaris rmk 700. It was a
mountain hill climb sled. Got a 144 track. Twin pipes. Cheater heads. Bunch of other mods. What will I need to get it ready and most of all where do I buy the stuff?
Here are a couple pictures of my cool down cart that I built 3 years ago, it is a contained system type with a 12 volt water pump and a cooling fan, the radiator was a A-coil from a home air conditioning system that I modified by stacking the two pieces and linked them together with some copper plumbing fittings and hose elbows,this cool down setup will cool my engine down in 10 minutes so the sled will be ready to run down the 1/4 mile again rather quickly, just like when racing on grass of course there is no snow to cool the sled down so a cool down setup must be used, otherwise you will have to wait a hour or so for the engine to cool down on its own before making another run,there are also basic cool down setups that use a plastic cooler with a 12 volt bilge pump to circulate the coolant but I don't care for those kind of setups as they tend to be messy and you have to keep putting ice in to help with the cooling,Ettenrmk said:Alrighty. I also have a 96 Polaris 600 tripple. And it has a 136 on it so maybe I could use that. I've been looking online for used asphalt skis and tracks and haven't found nothin yet. And I understand what to do with the suspension. But in not sure what you mean by build a cool down system for the sled after a run?
Yes, you have to have quick disconnects spliced into the coolant system on the sled, after a run you hook up to the cool down and in about 10 minutes or less the motor is cool and ready to run again.Ettenrmk said:Oh cool. So do u just hook up the cool down cart to the snowmobiles coolant system?
