Electric fan for cooling? Options

[teamgravy]

We are building a track car for endurance racing in Lemons/Chump Car series from a 74 914-4 1.8/carb converted. Rules state we have to spend no more than $500 on the car minus the safety equipment (seat, cage, tires, wheels, brakes, etc..)

I am thinking of leaving off the 914 cooling system and much of the engine tins and running a electric fan to cool the motor. The fans are cheap $70 for 2100 CFM fan and I can also use some big ducting to cool motor at speed. Elec is free (no night racing) right and no HP drain. Just loosing the 50lbs of fan/ducting on the front of the motor seems worth it.

I would build a shroud and use some of the existing tins push air across the jugs and heads. I would relocate the alternator above the oil fill/breather and run it off the small AC pulley that was behind the fan. Would love to buy a DTM or Fat 911 conversion kit but not allowed in budget.

I was wondering what the peanut gallery thinks of this.

Is this going to give me cooling issues?
Will ALT function from smaller pulley?

Thanks!
