I am tossing a big arsed aluminum rad in the 67 and thought this would be a good time to think about the cooling system as a whole. I have an external trans cooler waiting to bolt on and now I'm looking at the fan and was hoping to get some input from folks smarter than myself.
Although I don't want this to be all about my engine as I am looking for some general guiding principles in cooling rather than specifics for me but I am running a mild 351W today with approx 300 horse. I will be building the 408 next year once I get the rest of the car done and on the road which should be pushing a little over 400 horse and 400 ft lbs. (Still needs paint and headliner.)
I have an Oil cooler I could run on the car for cooling but for a 400-450 HP target I think that's a bit extreme and just another failpoint on the vehicle.
So back to the Fan question... Has anyone done a lot of research on the merits and drawbacks of mechanical vs electric cooling fans? My own brief bit of research and just logic would indicate the electrics would be far more efficient simply due to their proximity to the rad vs the engine fan which is a couple inches back.. Combine that perceived cooling benefit with the fact that, however small, there will be a slight engine stress relief/HP gain by removing the mechanical fan blades and it seems like a win win.
Anyone got any thoughts, experiences or feedback?
Thank you all kindly.
