Gosh, all I asked was would anybody be interested in a CD with plans for the intercooler conversion.

Now my two cents. I'm a pilot of prop driven small planes and from experience, I know that if I land at Flagstaff, Arizona which is at 7000 foot altitude on a hot day with a load of people and bagage and then try to take off at full throttle under those conditions the following will happen: I and the other people will die at the far end of the runway in a flaming high speed taxi.

On the other hand if I pay attention to 'density altitude' and volumeric effiency, and I wait until the early hours of the next morning when the air temperature is 30 degrees cooler, I will soar with the eagles.

After reading through all the "Analysis" on this thread, I called one of my former collegues who spent his life teaching diesel mechanics and in the course of that instruction won 15 national diesel competitions.

I used my fly or don't fly story on him and he verified that I was exactly right. Colder air has a denser concentration of oxygen molecules for a given volume than the same volume of hot air. Therefore, the existing fuel charge burns slightly more completely, resulting in more power!!!!!!! No additional fuel is necessary as it was already there but just not being burnt as efficently.

My expert further added (along with other posts here), that when the manufacturers of large diesel trucks started intercooling their trucks the resultant drop in the cooling loads was such that they were able to substantially reduce the radiator sizes on the trucks which allowed them to stramline the cab bodies. The expert states that without intercooling this streamlining would never have been possible.

The large trucks produced more power, got better mileage and as a consequence of much better cooling were more durable.

Now does anyone think these large corproations were going the intercooler route for any reason other than better efficiency? I think not.

I'm still going to wait until there's cooler air before I take off. That is unless my airplane is turbocharged 300D and intercooled!
