[QUOTE="oldmodman, post: 14677783, member: 10303"] You are correct. It's not a good idea. Info below for anyone that wants to try it. If you go to Kenne Bells web site they specifically tell you to use engine coolant for the front case coolant. And you are even told not to use chilled (killer chiller) coolant EVER. The chilled coolant would over cool the gear housing and cause clearance problems. The entire reason for the Liquid Cooling mod on their blower is to equalize the temperatures at the front and back of the housing. So 185 to 210 degree fluid will pull out the extra 150 degrees of heat from the front of the case and the bearing area. Without overcooling it and creating clearance issues. There are ways to cool the ENTIRE housing if you want to try it. Get a cold blanket with embedded cooling tubes and strap it down over the blower. You would still have a tremendous differential in case temps, but it would be top to bottom and not front to back. I have seen this being used on blown gas cars at Bonneville but their blowers were all race prepped GMC type blowers. And I am pretty sure that our screw type blowers have much smaller clearances. So, in the end go ahead and use chilled coolant for the Kenne Bell blower and report back as to you success or failure. [/QUOTE]
