I've seen them on TV, guy using ( or building ) a dual quad scoop

made of plexiglass, are these home made or you can buy it ?

What is the most efficent scoop for performance ?

Any infos.....

Dan

All of what I have seen are homemade.. the most
efficient one will have the carb at close to 3/4"
below the bottom of the scoop inlet.. if you can..
add in a ideal entry(thats a volocity stack)
EDIT
You can see the height of my scoop.. thats not even
on a tunnel ram.. thats a tall single 1050 with a
ideal entry on it.. the carb itself is about 3" lower
than the bottom of the scoop

Begin by calculating the scoop area, which will be smaller as the car gets faster.
Yes, I said smaller.

The, as much interior volume as practical. Ideally, the carb air horns are in still air.

The clear scoops are to see the arm drop or flashlight during street racing, There is no other reason for them. They certainly are not more efficient.

This is the scoop I just installed on my Coronet, the rear is completely open to the windshield and cowl, and I have 3"x9 Dia K&N filters on the carbs still have another inch above the filter and the scoop is 8" max above hood surface.

That scoop looks good Modelmaker.

Wedgeman, if you do a search on Yellowbullet there is info there on who makes/sells the clear scoops and why they use them.

I looked at the Hilborn style scoop, are they any good ?

That`s a very sexy scoop.............

They are not any good with the way they have those single or twin mini air filters. The air never gets a chance to straighten out. If you are running a blower then the blower stacks the air and negates that problem. I like the style of the Hilborn scoop. I have two and trying to engineer a way to make it taller and get a standard Wix air filter element to fit the opening closer to the opening(front) of the scoop. I'm also fond the the Thunderbolt ram air system. I don't like the clutter and the tubing, whether plastic or aluminum as it heats up and holds the heat, and negates the cooler air charge.

Chris Terry Racing..........about 2 miles from my shop builds them for a lot of guys

I once used a newspaper mailbox

Hopefully DusterDave will see this thread, he had a large Hilborn scoop on his blown Hemi that had a big flat filter in the bottom of it.

inovated racecraft sells those scoops you see on street outlaws,there like 200.00

Duster Dave used the Unifilter he persuaded into the scoop.
With these scoops the filters hold the scoop to the carbs.

How do you evaluate the front area (mouth)needed for an engine ?

I had the scoop that BDS sold at the time. It didn't have any provision for a filter, so I had to fab something that held a flat K&N filter.
It was OK for driving around town, but at the track, I removed it.
hemi-itis has the newer style BDS scoop, where they increased the size so it could hold a pair of round filters.

Forget the air cleaner....I look at the engine !!! wow
