Questions about 82-84 Trans Am Ram Air

The cowl induction hood ram air systems comes up for auction once in a while on ebay.

1) This was designed to work with carbureted engines correct? Can you use it on a TBI?

2) How is the solenoid activated? By a manual switch? A sensor? The computer?

3) I forget the third question. lol

Cheers Tom

Re: Questions about 82-84 Trans Am Ram Air

If it's an actual Ram Air hood, similar to the RA2, then no, it would not be used for carb'd engines.

Now if you're talking about an actual cowl hood, they can be used with any type of engine.

Re: Questions about 82-84 Trans Am Ram Air

I'm talking about the 82-84 Knight Rider hood... is there not a functioning ram air assembly that goes with it? maybe I'm confused... what does this go with?

Re: Questions about 82-84 Trans Am Ram Air

Ah, you're right! I completely forgot about the snorkels and some functional hoods that carb'd cars had back in the day.

As for them being functional, who knows, I don't. Would you be going for the basically hostorical factor of it? If not, I'd just get a simple open element, it'll perform most likely three times as good.

Re: Questions about 82-84 Trans Am Ram Air

The carburated versions functioned via an oil pressure, engine temp, and vacuum switch. Once the engine was running, warmed up, and during low engine vacuum situations(wide open throttle) the electric solenoid would open up the flapper door. It is somewhat over complicated but it was designed so it wouldn't open with the engine cold and cause a hesitation issue. You could simply installed an electric switch at the carburetor/TBI or gas pedal so it activated around 3/4 throttle.

Beware that there are two different style ram air setups. The carburated version with a offset round outlet hole and the CrossFire Fuel Injected with a central diamond shape outlet.
