Thankfully it was good weather at the last round of SLS. Knowing there is a high chance of rain at Knockhill I need to get a new front blower sorted. In December I had to stop a track day because I couldnt see where I was going in the rain.
I am basing my blower system around a 3" exit bilge fan for a boat. £17 on Ebay. In all I think the kit is about 1.5kg.
The 4th gen has its front screen air channels built into the chassis so there is one big hole to direct air through
Likewise there is the outside air feed hole
I had to cut out a base for the pipe flanges to connect to so they are able to blow air without a load of leaks. I used 2mm perspex.
Front window vent with the flange dropped in to test the fitting.
Completed outside air feed. I didnt need to use the jubilee clips as the 3" pipe was such a tight fit that I need to use boiling water to strech it on. Once cooled I cant even pull it off.
The fan is half in and I need to sort the wiring. I have a switch for it in my centre console.
