Eh, ton hood que tu ma envoyé de midwestrestorparts, c'est tu un ram air ???

Eh, sa se vendrais pas le dessous d'un hood dans le neuf ???

Je viens davoir un mail d'un nouveau copain, a propos des ram air d'un hood gto 69.

Mon ami 427COPOZ, ma dit le contraire si je me souvient bien.

alors jaimerais bien en reparler et savoir la réponse a ce mystere...

Et il me dit qu'avec un hood Non Ram-Air c'est possible de faire un hood Ram-air. Il n'a qu'a changé les scoop.

Tu verrait que ce n'est pas juste une question de scoop que tu voit
sur le hood un système Ram-Air.

Q:
What is a "ram-air" intake system?

--------------------------------------------------------------------------------

From Jon Steiger:
There are a couple of different "ram air" systems out there; one style uses a "ram air" hood which has a scoop that is sealed off to the air filter underneath. This is the most efficient type. The other style involves a cover that goes over your air cleaner which has a one or two openings on it (usually two) which allow a couple of hoses to be connected to it, which are routed down to the front of the truck, either behind the grill or under/in the air dam. The purpose of both systems is to feed the engine with cool, outside air rather than hot under-hood air. The hood scoop ram-air systems are more efficient because the air has a more direct path to the throttle body, and the engine doesn't have to suck it in from as long a distance. Also, with the "tube style" ram-air systems, the air is heated as it travels through the hot tubes (which are generally located right over the hot exhaust manifolds or headers). As the air is heated, it expands, so for a given volume of air, hot air will have less oxygen molecules in it than cold air; the more oxygen you can cram into the engine, the more power it will make, that's why colder is better.

One qualification I should probably make is that neither of these systems are truly a "ram-air" system (on a street car, anyway); more like a "cold air" system. A true ram-air system will actually ram the air into the engine at a pressure higher than ambient. (i.e. its sort've like a mini-supercharger effect) However, you need a big scoop and you need to be going *very* fast. As a point of reference, a "standard" supercharger will generally make between 6psi and 9psi of boost. A salt flat racer going 300-400mph with an average sized scoop will generate about .25psi of boost from "ram-air" effect. So, the amount of "ram air" produced by a street car going 60-100mph is basically negligible. However, these "ram-air" systems are still good for street cars because, although they don't build any real pressure, they *do* allow nice cold air to get to the engine, so they will make power based on that alone. In my experience, adding a "ram-air hood" style system to a 318ci Dodge Dakota will drop your 1/4 mile times by about 3 tenths. A "tube style" will drop it 1 to 2 tenths.

pis sa se vend pas en reproduction ce morceau ?

Ya tu juste uniquement les "Judge" qui avait des ailerons ???????????????????

ok,

merci copo,

selon toi ,yavait beaucoup plus de chance que ce soit les Judge qui était équipé d'aileron.

Parce que sur mon couvert de valise, ya des trous pour un aileron.
