That looks cool , I’m trying to understand from the pics where the blower is. It looks like it’s by the battery. Which is in front of the firewall area. I’m thinking of a similar idea but mine is a Teryx 2 and the back of the console has a Recessed pocket. I was going to do a 4” schedule 40 pipe with a 90 * and then the blower in-line to suck out the hot air.
I recently installed a 6 inch fan over the vent in front of the shifter. It seems to help a good bit with the heat. I just did a manual on off switch from the 12 volt receptacle so it will turn off with the ignition as well as the manual switch. I have 2009 T2.
