I have one and they do look cool, but hooking up the butterfly's is all up to you. I am still trying to find something that will reverse the "throw" . And from what I have seen/found so far either the linkage kits cost more than the scoop itself did, or it simply wont work. Here is what I have so far, but the linkage rod doesn't flow with everything else. I am trying to get the "red" actuator arm in the down position and still have it throw the flaps in the right direction (top of butterflies inward). It works great now, but as the picture shows it just looks out of place.

What if you moved the tie bar and the scoop linkage to the bottom of the carburetor linkage, then you should be able to flip the red arm arround.

doing that reverses the way the butterflys open , the top would actuate forward and it looks goofy,
I have thought about running it off the other side of the carbs,  (make an arm that screws right to the throttle shaft) but I am thinking it might strip it out, and then the carb will be toast, or at least the baseplate.
It works great how it is, I can actuate everything by actuating the tie bar. It beats the hell out of trying to find a spot to rev it without getting cut or pinched.
I will probably leave it how it is now, its strong and pretty much bulletproof, If I can come up with something that will be as good as what I have now but looks cleaner then I'll do it, but for now its a keeper  ;D

What Josh it suggesting should work.  If you put the red lever down and move the throttle end to the lower 1/2 of the throttle lever (below the shaft), the lower 1/2 of the throttle lever moves forward as the top moves back, and with the lever on the scoop turned down will open as designed.

If you can understand that I need to put you to work.

I see what you are saying...  You might even be able to shorten the linkage rod and operate form the front carb.

Then the goemetry is off, its alot trickier than it looks and I still dont know if I have it opening quick enough at the beginning, to slow at higher speeds, it should be ok it gets alot of air as soon as they start to open...we will just have to give it a lil test when I get it put back together....getting close. ;D

I spent a whole weekend moving the linkage configurations around, between mounting the throttle cable (from the front, to the rear) getting it to respond at a longer throw (slower) but more pedal action, I had my girlie pull me up skiing last summer and I had the "Quick" response action. She about ripped my arms out of my sockets when she nailed it. So that is/was first priorities, then came the butterfly's, running the linkage to the bottom of the throttle lever didn't create enough throw to open the flaps even half way, I could make an extension that could "counter" the adjustments on the "red" lever but after all the ways it might  work I decided I could live with this until I had time to research more options. Now that I am familiar with the dynamics of it, I will keep looking around and I will find something that will make it look as clean as the rest of it. until then I will run this setup.

I love mine (though it's still not on the boat) and am starting to put my ideas together on how I am going to run my butterfly.  Regardless, I think Dozzr would agree these things are bitchin. Not cheap but killer looking nonetheless..

Well, if I had told a couple of my techs what I wrote or made one read that post I would have gotten a blank look like I had asked them to build an airplane out of toothpicks.  :screwy: I would have to point and say put this here and this here and find me when your done  :banghead:

Most of the time we are looking for good techs with diesel, truck-motorhome chassis or automotive experience.

Yes, they are very cool looking, looking at it head on sitting on the tunnel ram the girls said it looks like ET, I dont totally agree but it was funny.
 Nordic , I hope we havn't scared you off  ;D
 crewchief, thats funny you said something, I thought about it and wondered what/who you worked with that could possibly understand that. I pictured just what you were saying and it made perfect sense but without it so clear in my mind, I would have said WTF you talkin-bout"  ;D
I worked heavy line for Ford for more years than I want to remember, I think I am pretty much spoiled now, all these shiny new parts are way to much fun to work with.
 On the linkage, I turned the actuator down, made a longer rod, moved the heim joint on the scoop as close to the center as it would go, re-located the ruturn springs and "WALA"  (it only opens to about 90 percent) but that should be plenty, those holes are huge  ;D
Here is what it looks like now

If you eyeball the angle to the front carb to the bottom hole you can see where it would be  slightly overextended. I could make a pivot arm or something, but I'll check this out for a while, then decide.

If you went to the front carb with a shorter rod and moved the linkage on the scoop a little bit, I bet it would go to 100%. That is how they are designed, and that longer rod loses leverage and motion through the arc.

Well I have the old rod, so I will give it a shot. It will be close, and being that close to overextending I'd hate to have of all things the throttle bind up while hauling ass. But I have time to goof around with it while the engine is getting finished up. I am going to miss having a tunnel ram for an entertainment center decoration  ;D

Set it up at 100%, and let it sit where it does at idle. You have a carb, not an EFI hat - so it's not controlling the airflow into the engine at idle. The engine pulls so little air there that the gap around the blades isn't even going to be a restriction.

no , you definatley didn't scare me off. i dont have an open motor like most of you guys do, i have a fiberlgass hatch with the jumpseats on either side. so i looking for a scoop to have stick through the hatch. i think this one would look awsome. i am a fabricator for a living, so i dont think i would have much truoble getting the linkage right.
i do have a question though: is it strictly a scoop, or does it have an air filter element, or arrestor inside?

They come with either a single or dual carb mounting plates and you just get the two cheesy paper filter elements wit it, I have 1 spark arrestor, and am looking for a second one
