My personal expertise is finace and investments: but, I admit to being an amateur engineer. I am trying to get as HP out of my 1985 3.2 Carrera as possible in DE and autocross events. There is a classic text, "The Sports Car Engine" written by Colin Campbell in 1964. He states that: "since motor racing is a warm weather sport there is everything to be gained by trying to draw carburetted air from as cool a source as possible" He goes on to calculate something called "Charles' Law" to illustrate that you can gain 1% in brake HP for every 4 degree centigrade drop in aspirated air temperature. See page 244 for those few who still have this book. He also speaks of the boost to the induction system from the forward velocity of the car, and if this air is directed into the induction system it will also lead to a further increase in HP. I am probably one of the few people who still has this book - I owned a TR-4 many years ago and also tried to get as much HP out of that beast as possible.
My question is: if I rigged a piece of flex pipe that was sealed at one end to the intake of the air filter box and the other end was placed in the air intake area of a Carrera tail, would I expect to see a HP increase. Some may say: why bother it would be small. I say it is a 20 minute $4.95 modification. Could it be that cool air ramming on a fuel injected engine has less of an effect than it has on a carburetted engine? What do you engineers say? It seems to me that some of the big old V-8 muscle cars boosted of cool air ramming. Why wouldn't this work with a 911 with the cool air pickup located in the air intake of the wing, in that location it would certainly pickup cool air and the ram effect could be significant. Some of you will note that I am the same guy who asked the question about the chin spoiler a few days ago, after reading everyone's comments I have decided to go with both the spoiler and the wing, it seems to be the safest way.
