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! |

I'd worry about cooling the brakes and leave the engine cooling stock ,maybe an oil cooler with a fan on it....my friend ran it in an Alfa and said the brakes went away quick...those are really. Fun events with great looking,funny ideas but be careful !! I think it's just a matter of time before there's a fatal accident ...

I can't remember it if was Le Mons or Chumpcar, but apparently the driver had a massive heart attack. Very sad, but it was not contact or collision related. |
