Here is the other part of the big picture which seems hard to actualize...

I am assuming no refrigeration equipment is being used... so we are basically talking about a heat exchanger... an air to air radiator...

So we have the air which has been compressed and heated some by the very act of compression... in a chamber which has tubes with outside,non compressed (except a little by the fan) air flowing through them.... this is what is going to suck heat out of the compressed air and be exited from the system...

How much ambient air at what temperature would be required to produce the effects being claimed?

I assume it would be more ( and I think MUCH more) than the amount of air being consumed by the engine...

at 2000 rpm the engine is consuming 3000 cc's times (1/2 times) {only half fire per revolution) plus the added amount of the boost... lets use 10 lbs .....

Lets assume some friction restrictions in the tubes of the cooling air...and that we need several times the amount being consumed by the engine in order to produce this much cooling...

Is the cooling fan capable of providing that much flow through this system ?
