How did that work out ? Was there any power found at the track ?
I have no issues with a stock 3 core and flex fan with a filled block.
But, I do run 2 classes when I race and go a lot of passes on a good day so I bought a Derail 4000 cfm duel fans, Meziere water pump, setup and a big aluminum 2 core radiator so I can cool between rounds. Also bought a solar battery deal so I can run a charger without having to listen to a generator in my pit. Can't stand those things.
There is some controversy about any seen power difference being a wash because the alternator just pulls harder on the belts.
Still have the belt driven stuff in the car and probably will have it all season.
