I ordered a pin on hood instead of the heavy bolt on I have pinned on now and am considering a cowl ONLY if it`s actually faster. I would totally seal either scoop and my cowl opening is sealed off which might help the cowl.......... 72 Dart 470 n/a BB stroker street car `THUMPER`...Check me out on FB Dominic Thumper for videos and lots of carb pics......760-900-3895.....

No hood won over both hoods in ET the cowl was a tenth slower over no hood and the 6pac was about 3-4hundreds. the cowl went the best mph(1) but killed the 60ft so maybe the weight of it hurt it.we lightened the hood slightly by removing the seal to the carb but havent had a chance to go back and give er a try.

I may cut a 6-pack scoop in the middle and narrow it unless you guys think that would hamper it`s design for air flow. 72 Dart 470 n/a BB stroker street car `THUMPER`...Check me out on FB Dominic Thumper for videos and lots of carb pics......760-900-3895.....

Just to get the opening off the hood and raised any does help from what I hear. In other words have it so the bottom of the scoop opening is not right on the hood as I believe it works better to raise the scoop some even if only a 1/4" to get the scoop up in the air stream and get the opening off the hood itself. Like what the snorkel scoops did in Pro Stock in the 70's. Actually going by that standard means my Max Wedge scoop really dont work good at all the way it is like they were stock. I believe the trick on the front open scoops is to get the scoop up in the air flow better as flat on the hood is not as good air flow into the scoop. Ron Last edited by 383man; 01/26/13 03:31 PM.

And then my buddies areo scoop you can see where it is lifted some off the hood so the opening is not flat on the hood. This seems to work better by the way the air flows over a hood.

I havent had much work with the cowl scoops yet but I have a cowl now on my Rampage and will start testing this summer

On a daily driver I would at least try to get a portion of the inlet above that line...any bit will help... remember that you can move the inlet forward and get above it... thats why you see some GM cars with the opening right near the front

Dom just thinking out loud here wile having a couple So I hope it don't turn into a fest on me Hows 'bout (I'm not a fan of them either) a cowl scoop closed off at the back with 2 custom air inlet scoops on each side in the front. Maybe you could graft something like a pair of Cuda or Chally style scoops in there. Who knows maybe the nose of your 6 Pack scoop can be grafted near the front. It would be low and street friendly and pick up some air from the nose of the car. It would certainly be original Or maybe I need

That's why there's lower pressure at the cowl. The air closest to the hood is not effective for ram-air; about an inch above the hood is where you start to get into high pressure. There's a drag penalty for too big, too high, too large an opening. Ducting air from the grille area is pretty effective, but it gets heated on its way to the carb, and intake holes & packaging can be a problem. Look around on the web for the aero test pics on the Mopar Missile Duster, where they tried different scoops.
