Sealed Hood to Air Pan #917145 01/30/11 03:45 PM 01/30/11 03:45 PM

gearhead01 OP enthusiast Joined: Dec 2008 Posts: 202 Illinois	How many have a sealed air pan to their hood scoop? Is it worth the effort? I have a glass hood with a 6-pack hood scoop. I have been measuring and sketching. I will have to put a panel on the bottom of the hood to reduce the area, and an air pan that is approximately 18" long and 20 inches wide that covers over the intake manifold. The cooler air will always help, but i will get that with an unsealed scoop. Do you get much more HP from the "ram effect" with the sealed hood scoop? Thanks for your inputs.

It will prevent the carb from sucking in hot underhood air, and that's all. For that reason alone it's well worth doing....it makes a noticeable difference on most cars, and it did on mine. Rich H.

Put a tray on it to seal the carbs picked up.06 in the 1/8 mile. "To Be The Man'You Have Got To Beat The Man" "T/D and Pro-Bracket Racer"

John Here is my set-up for the same application. Seals good,,,still working on getting the #%&!!* thing to work though!! Seems to get TOO much air/turbulence in carb above 50 MPH. I had a thread on this awhile back. The tracks closed before I could do anymore testing to correct problems.

I can use the air filter(3") in there too with the cowl hood. The 6pk scoop won't allow the air filter as it hits at the rear of the scoop. If you like drag racing, support your local track.

I am figuring at least 1-1/2" clearance on each side to the air pan side/seal side walls. This will allow air all around the air cleaner. The 14� diameter wir filter will clear the inside of the scoop, with around an inch to spare. I can see that the 16:� diameter is just large enough to hit the scoop. Thanks everyone for the input and pictures. I am going ahead on construction and will post some pictures of the results.

gearhead01 OP enthusiast Joined: Dec 2008 Posts: 202 Illinois	Chapper: A question about the turbulence. Is this with the cowl hood or the 6 pack hood. I have heard about issues with cowl hoods having turbulence problems. The fix was sealing off the grill openings in front of the windshield. The air turning at the back of the cowl would go down in the fresh air grills and never get into the rear opening of the cowl.

Maybe, the 14" might help, I'll have to do some more checking when I can get the car out of the trailer and into the shop. Also, the turbulence, or 'what ever' that's going on in there, is with the 6 pk hood. It runs fine with the cowl hood. I was trying to get cooler air to the carb when I built the air box/pan. I tried it first with the scooped hood and it was a disaster!! After I reached about 50 mph,,motor just broke up terrible. It sounded like it was drowning with fuel. I let up quickly and slowed down which eased the comotion and I idled back to the pits, changed hood back to the cowl and ran fine the rest of the day. Can't hardly wait for good weather again. I was just getting back into the swing of things!! If you like drag racing, support your local track.

It worked terrible. They put on an air filter and a scoop and the problem went away. Seemed to be reducing the turbulence over the carb mouth was the key, and the air filter helped a lot there. Plus there are all the other benefits of an air filter. https://www.facebook.com/THENEWCDRA Proud member of the liberal scientific elite

Many years ago, I was waiting in staging with the hood open, and a consistant winner walks by, and says, sealed hood eh?, walks on by. I started thinking about that, and my theory is, without the seal, the engine is getting a blend of average air. Round to round, it seemed to make the car tighter. That's what I think Bruce was getting at. Could be another WAG on my part too

Most of the time being the scoop opening is not large enough,also some scoops just will not work on some cars. You may also need to go up on your jet size a few steps. The extra air can cause it to lean out.This will most likely be your problem than the scoop opening being to small. Last edited by MRMOPAR570; 01/31/11 12:25 PM.

The opening has to be in the boundry layer which is a few inches higher than the factory scoop opening. As the car moves forward the front of the vehicle diverts air up and over the scoop and very little into it.

Simple test..tape several stips of yarn in front of your scoop and have someone observe or camcorder the way it behaves at speed. 6448701-998852905_4DmMz-O[640x480].jpg (332 downloads) The little old lady from Pasadena is back!

My question to this is,,,why do all the Super Stock cars run them? I realize they are correct for the car. If they don't allow enough air in,,how do they run so good? Record holding cars are the opitome of research and development. If the factory hood scoops don't work,,what are they doing to make them work? They can't be raising them up to get into the 'good air'..."straight line between roof and leading hood edge"... If the factory scoops aren't doing any good,,why don't all the people run the cowl hoods that all the Mopar people hate? I don't really care about what is 'correct' or 'legal', I am just trying to get some cooler, fresh air into my carb. I am not trying to be a wise act,,just trying to figure out some things. I will be doing some more testing when the weather gets better and hope to get this hood/scoop thing figured out so it will work like it should. As for the SS/HA cars having sealed scoops, they would probably lift the hood off or rip the scoop off if they were sealed!! I still can't imagine how they are NOT having air problems with all the air going over/around the carbs,,,UNLESS,,like others have said..there isn't enough air going into the scoop...? Maybe they are losing some ET..??..I doubt this very much! If you like drag racing, support your local track.

For testing... take some cardboard and tape it to the current scoop but make the front longer so its closer to the front of the hood... tape it to the hood to simulate a sealed scoop then run it(come warmer weather)... I dont know what the SS guys are doing... I've never looked but maybe they dont seal it... or they pull in air via tubes

That's why the SS/H cars don't seal them. Some scoop designs cause turbulence around the carb and screw the fuel signal up. Some of the stuff out of the factory was for show and a little for cool air.

That may be the reason,or there is just not enough space when they are sealed to the hood. If I were you I would not go with the factory style hood scoops. They look the best on the cars,but they may not be the best. I put a cowl hood on my 67 R/T and pick up another .05-.06 over the factory Hemi style scoop that picked up about .06 in the 1/8. In all I picked up a little over a .10 with the proper hood scoop in the 1/8 mile. "To Be The Man'You Have Got To Beat The Man" "T/D and Pro-Bracket Racer"

There will be no greater than gravity pressurization, however, unless the scoop opening is in the boundry layer and even then an improperly designed boundry layer scoop will cause more drag that will not be compensated for by any additional power.

I'm sure some of the scoop Mfgs like Harwood will sell the sealing foam, but I got mine from Home Depot ( probably not fire resistant though ). Cut my hole with a saber saw. Cut another circle 2" in diameter larger than the hole in the hood. Glassed it to a 3" tall air horn. Secured it to my carb with a cross bar bolted to my air cleaner stud. I can run with or with out my K&N air filter this way. Unless conditions are real dirty, I race without the filter. IMO, no matter how big your filter is, they are a restriction. If your car runs better with a filter, you got another problem. Beautiful car BTW! Fastest 300

PS I have also saw some big scoops on cars,but they only cut a small round hole in the hood. Last edited by MRMOPAR570; 02/01/11 01:36 PM.

I believe you meant to say ABOVE the boundary layer. I've always had a mini-airo scoop with a K&N flat panel filter mounted in it's base and it has always been a predictable car. One reason for the filter is to keep junk out of the engine but I also did it to stabilize the air above the carburetor. IMO, if you just have a hole with a scoop above it you're gambling in the unpredictable and often counter intuitive world of compressible fluid mechanics. My filter might cost a little top end speed but I'm a bracket racer not an ET chaser. The shape of the air stream above the hood likely has many influencing factors such as the length of the hood, angle of attack, and the shape of the nose of the car before the hood. Trying to find a solution that works in all cases is most likely a lost cause. My new plan is to go back to a stock hood (in glass) and take air from the nose of the car on both sides of the radiator. I'll also install air deflectors behind the grill to try and generate some additional pressure. As it is, I have around 2" from the top of the carburetor to the underside of the hood. Since the venturis are 1-13/16" (with annular boosters plugging them up) I figure the air should be fairly lazy making the bend and it will have the full 360 degrees available. I wouldn't put a cowl hood on anything. Those things look totally 'High School' to me.

The message that it takes a specifically designed aftermarket hood to achieve any kind of positive pressure at the carb is valid, though. Even the best designs aren't really hugely effective as any HP gain has to be above what the addition scoop drag negates. A bad design can even venturi pressure out of the scoop. That's probably why the SS/H cars aren't sealed.

Big motors generate big heat, which means big radiators and big fans, which means much higher than normal engine compartment pressures and temps for stock bodied cars. Another reason to run a sealed scoop. One of the tricks that was used with the early max wedge cars was to raise the rear of the hood - and most were running sealed scoops - even if they were in the boundry layer - cold air was first and formost. 6450838-scan0002.jpg (152 downloads) Fastest 300

As the speed increased, the doors closed by gravity and were pressurized by velocity -- interesting but marginal effective. Like the blow-doors on a jet fighter.

I plan to use an air cleaner, using the base of the air cleaner to mount the air pan. Worst case, I can always take it off. If I can, I will devise in a monometer to measure the actual pressure in the sealed portion of the air pan.

I went to a tapered side design to give more access around the underside near the carb. And, give more airflow room around the air cleaner.

I just saw where Tuff Paw is making scoop trays now. Might be a good place to buy from or get some good ideas. "To Be The Man'You Have Got To Beat The Man" "T/D and Pro-Bracket Racer"

I used 2x2" air conditioner sealing foam from the local hardware to seal mine but Moroso has a foam kit that I believe is 1 3/4" thick by about 4" wide and maybe 2-3' long you can buy and trim to fit 416 stroker from Nick at Compu-flow. 11.14 in full street trim. Seems like a new best every time out. 11.06 open headers----so far!!
