oil coolers

Rono Old style fed one way in at the dipstick and used an over flow stand pipe to drain to a receiver tank then to a no vain type fuel pump to radiator and then back to the S/C. Best is to feed through the shaft with a reed air swivel, This setup directs volume of oil right to the heat source and protects the races from damage from over speed of the unit. To cool the air the best setup is to pressure reference a small alcohol tank and use a pressure switch to open a valve to feed an adjustable nozzle that sprays directly into the S/C inlet. Cools the air and S/C and feeds more alcohol/fuel at higher RPM. Makes carburetor adj. easier as more pressure needs larger jetting and fuel flow. As pressure increases in tank, flow in S/C and engine increases. John Erb Holly NG in cold weather thick oil

        Cooler air to an engine effectively increases the octane of the fuel and allows more fuel mix into the engine. Cooling the S/C and the air is possibly best done with an ERB cam that is specifically... more
