The difference between "Bird and "Bug" Catcher Injectors

[Mid-life Crisis]

Can someone post some pics of a bug catcher and bird catcher injectors on top of an 8-71 blower or larger. I am thinking about putting a bug catcher on my K-boat because I've been told that it will be easier to drive but that "you're going to hate how small it looks" or "don't be a pussy, put the bird catcher on there like everyone else". I just don't like the look of the 4 port hilborn injectors, so they're not an option for me. Any thoughts??

A Bird Catcher has Smoother transition from Idle to full throttle. Witch makers it easy to drive and tune at lower RPM’s ( See Below) Here is some picture of my Bug Catcher on a 871

In diagram A, below the machine surface on a Bird Catcher extends deeper into the hat.

In diagram B on the Bug Catcher the surface drops off in to the casting, so as soon as the top side off the bug catchers butterflies get to that point it will flow more air then the Bird Catcher. This makes for a quicker transition from low RPM's to to higher RPM's, and it also gives you less resolution in the throttle at lower RPM's.

What I can't figure out is:
My Bird and all that I have ever seen....tip the butterflys out at the bottom to open.
Then I see this drawing.
So..then I go to this site and look at a bug. http://www.goodvibesracing.com/Product-Scans/E-4005F.jpg
That's the bug I remember and the butterflys work the same way..tip out at the bottom to open...or so it looks as I cannot see the barrell valve linkage.
Then I look at your deal and the injector looks different (besides the 3 ribs removed) and I see your throttle cable positon and it looks like the bottom of the throttle blades tip inward....the opposite of the birdcatcher.
Is that right?

[Mid-life Crisis]

It sounds like you are saying that the bug catchers would be even less controllable from lower to higher rpms. Can this be right??

[Fiat48]

No. Not saying that. Not saying anything but wondering what the deal is with his injector.

I also thought the norm was bottom out.

Questions:
How many companies have manufactured Bird and Bug catchers?
Out of those companies, how many revisions have each company had on the Birds and Bugs?

I was referring to the previous explanation on the diagram. Sorry.

Only Enderle. His invention. Bug was first, then the Bird in later years, then the Buzzard.

Flat48 you are right my diragram was wrong so I fix it with some pictures. It's easyer to see and I should of done it this way first GOOD EYE!!

Ok. I see now at the top. Thought that but the pic and the diagram threw me.
Knowing that. The position of your throttle arm worrys me. It being so high that when the throttle cable pushes it...would not your throttle cable be in rather a cam over position? Please check that. I think you should consider moving that linkage arm to a lower position....so that you have only a straight up push on that lever. I feel there might be a danger of throttle hangin open.
Maybe it's o.k. but take a look.

It looks the same to me, it seems like it's 3/4trs open when closed???...

I was always under the impression that the throttle cable should be pulling the throttle open not pushing it. That way the cable dosen't have a chance of bending at all. Have I been wrong all these years?

But every peddle I ever saw pushes the cable. At least on V drive deals.

[stix818]

All of ours push even my old man's PGF. As long as you have the geometry right you don't have a problem. Those cables are pretty damn strong!!!

[Roaddogg 4040]

It has been so long since I had my V Drives that I can't remember if I put in push or pull throttle cables but I think that they were pull. You have to route the cable a little bit different but it isn't a big deal. Maybe I'am just too old :) :) :rollside: :rollside:
