Help me understand why we are doing all of this air the way we are. We are working to keep clutches cool correct? If that is the case why do we pull the air out where the clutches are? From what I am seeing we are pulling fresh cool air from the mag side. Pulling it over a hot pipe, over a hot motor to try and cool our clutch with all the hot air form under the hood. What if the fan was on the other side pulling the hot air out that side?
Or is the vent on the mag side to let air out? I understand I maybe looking at it all wrong but I think about all of the under hood heat that we have and then we pull it all where we want to cool.....
actually there are input vents all around the clutches to push cool air in and hot air out both sides by your knees, with the fan on the clutch side to draw out even more hot air. many times those vents get covered with snow and ice, but the blow hole keeps removing hot air from the clutch compartment. Its not going to eliminate all the hot air under the hood but if it can reduce temps by 40 degrees thats huge. (* disclaimer i have no idea how much it reduces temps, but just know that it does reduce under hood temps)
This kit worked awesome in the deep snow, in the tight trees where you arent moving fast. When you are able to move fast and have airflow (climbing hills, fast side hills, etc) having some good panel vents will move more air across the clutches. For me the combination of 2 cool air vents and the blow hole covered every riding condition i encountered last year.
I dont have any temperature data, but I do have the grab a clutch and belt feel after playing in the trees getting into some of our secret stashes and the sleds with the blow holes are noticeably cooler.
