3.0 cooling option Options

[RKramden]

I think I know the general response, but I’ll ask anyway.
Putting a 3.0 performance built (premium pump gas) into the 914.
No intention of racing. Maybe an auto cross or track night, or terrorize the neighborhood, but mostly C&C and PCA events.
No heat exchangers ( So.Cal), an oversized oil tank in the engine bay, and a 916-6 type engine lid.
In lieu of a remote oil cooler I was considering changing the fresh air fan piping to blow back through the heater longs up through the tins and outlet right next to the engine cooling fan inlet space. Or possibly just blow on either side of motor below the tins.
I’m wondering if this has ever been done successfully or if the idea makes any sense at all? Any thoughts or suggestions would be appreciated

The fresh air fan hardly moves any air in the cabin. It's not going to do anything to cool the engine.

Are you ever going to be going up a hill on a hot day? Stopped at a light for a while or stuck in a traffic jam on the road with the asphalt radiating heat up into the car.
