I went through the same issue before I sending a set of friction plates to wpc treatment, I was spilling differential fluid everywhere... now, nothing, absolutely nothing. ( I also reduced from 100% to 80% on my cusco RS)
I just have the nismo cover, the long hose, a fuel filter in the middle and the external overflow bottle.
my lap times are "decently quick"...

So you are to actually run ducts from your windows to you cooler? How well does the bilge pumps hold up to heat? Going ideas and pics

I think I will try this for a switch

That looks like a good kit. Just for the love of god don't use those self tappers. Or crimps. And especially not that tee-wire crimp thingy that's notorious for breaking wiring!!!

The current plan is to run NACA ducts from the rear quarter windows, we will see what actually happens over the course of the winter. The bilge fans are doing just fine, and are a good alternative to more expensive small fans.
