title says it all, have you tried the horizontal fan system from reichert? at the autocross, saw a guy running this setup on a 2.7L type IV monster...

Thanks for the answers guys and sorry for the thread hijack. I think I am with you now on the pressure issue. What threw me was the statement that "pressure is how these engines are cooled." Your context explains that statement. Pressure is just one of the many factors involved in these systems. If I understand you, the pressure drop doesn't actually provide the cooling. Pressure inside the plenum enables the air flow to be more evenly distributed through the system. On the other hand, it sounds to me like the 911s work more like a free-air system than a forced-air one.

But we still have an issue with 914s. Bug fans can be over- or under-driven (within limits) to match the volume or velocity needs of a particular system. Since the 914 fan is direct-mounted we are stuck with it and its output. Design-wise I would guess it is more like the bug fan: high pressure and high velocity. So any improvements to the cooling system itself will result from changes to how the airflow is managed. I guess from your statement that the pressure under the stock tins may be either/both too high or low, or unevenly distributed. You're working on the top tins. Could anything be done on the bottom ones? They seem really restrictive.
