Do Pontiac shaker hoods actually increase power?

    1. The scoop is backwards
    2. It's in a low pressure zone in the center of the hood
    3. If the carb is sealed to the scoop, wouldn't the car run lean or not pull to the top of the rpm range due to it literally running out of air that passes over the scoop?
    4. School me on this, guys that have had any sort of Firebird or Trans-Am

    Where is the highest air pressure on a hood? Check the LS6 cowl intake - a few inches south of the back lip of the hood and it works.

    Probably not, but it looked so cool!

    I read an article years ago that tested all the performance ram air systems of muscle cars. Even the 70-72 "salami slicer" ram air hood didn't fare too well. I could be wrong, but I could of sworn that it said the GS hood actually sucked air out of the hood! I honestly don't remember much of the details of the article but I do remember the one hood that worked the best- the 440 six pack A12 hood. Big scoop facing forward above the boundary layer of air

    I had two ‘79s, a 403/auto/2.41 geared one and a 400/4speed/3.23 one. I cut both scoops open so that they worked. The area below the windshield is a high pressure area, air stacks up there and then flows forward. It was cool to drive one in the rain; the beads of water would roll to the back of the scoop then fall forward as the they were sucked in.

    I always thought that it let hot air out at an idle or traveling slow .

    My guess is the Pontiac shaker does squat. It sure looks cool though.

    Heck yeah! Layne (alaskagn) has had a lot of them. I used to be a 5.0 Mustang guy, and I could never catch him in his 'birds, no matter what I did to them. That white one I posted is a wicked piece of equipment (550 rwhp if I remember right). The black one is completely stock down to the air filter and catalytic converters.

    That's the opposite of mine. White one is totally stock and Black one is modified. lol :D

    I think you’re right. That and the 70 Challenger T/A scoop maybe.

    The GS scoops were too far back and low to do anything.

    I think the Olds scoop near the front worked well.

    The Cowl is still in use today in NASCAR.
