Non-engine running oilcooler.  With just two electric squirrel cage fans to cool the cylinder heads and no oil cooler the engine oil gets to hot during the drive back to the pits.  During the cool down time the oil doesn't cool down enough.  I bought a heat exchanger off a tractor and a Holley Blue electric fuel pump (110 gph) from E-bay.  At the finish line I turn the oilcooler on and the temp doesn't rise anymore.  At the pit site, I leave it running and the temp will drop 25 degrees in 15 minutes.
