3. If we could find a way to smooth the the fins, and I mean really smooth, like a mirror (some sort of external extrude hone?), that would help the cooling efficiency. One word: Nickies. Oh, make it two: Xtreme Cylinder Heads

4. Flat fan. Cylinders 3 and 6 get screwed for airflow. A flat fan would help a lot. What's a repop flat fan cost these days?

5. Improved efficiency fan. You can tell our fan is crap because the blades are straight. Every engineer knows that the tips should be curved backward for better efficiency. It would be quieter too. Like a 993?

6. Air to water intercooler. Stop dumping the hot intercooler air into the engine. The air going into the tail should just be for the engine. Laminova, the only way to go.

7. Direct injection. The vaporization of the fuel cools the combustion air. There are turbo motors out there running 10:1 compression and 1.5 Bar boost with direct injection! Hold tight on this. There are some prototype direct injectors, integrated w/ spark plugs in R&D with some of the big auto parts manufacturers. Imagine twin plugging a head with a set of DFI/spark plugs w/ ion sensing for knock! It's coming.

Of course you can run on tolulene, spray liquid N2 into the fan, and all kinds of wild stuff, but these are things that are practical, and we would have them today if Porsche could have stuck with air cooling.
