yes, the Demon is and the Eddy Thunder series are copying the TQ air door, which was very successful if tuned properly. Also, check at some point check and see if you have any adjustment on how far that air door comes open, that's key as well. I think the Demon carbs will work great once tuned.
Yes the air door is spring loaded and you can put more or less tension on the spring. Most are saying to put more tension on the spring and not let it open. I may need much more tension..
the spring adjust how fast the door comes open. But, there may be a way you can adjust how FAR it comes open as well. That's critical as well. When I was running TQ's years back, they had a tab that you could bend (it was slotted to bend) that controlled how far the door opened, and the spring controlled how quickly it opened.
Honestly it seems like there's a lot of room for air to get around that door even when it's closed.. I'm pretty sure there's only the tension not a how far can go adjustment... remember I don't think this motor is going to suck the whole 1250 CFM LOL..
I need to look at a demon carb.... now you have my interest... LOL. I'm betting the design of the door is molded to start the syphoning of the back barrels. That's why the eddys and TQ's have funky shaped air doors. Vacuum pulls the door open, but the door design in pulling fuel rapidly. Maybe I'm just too old school and I can't leave the TQ design. Maybe the Demon is completely different. I just can't imagine it working differently.

wait.... I see …. I'm studying these right now in images...View attachment 1715475552
There's only one rod that goes over the top and that actually works the choke flap. I know this how it's conveniently ran right across the little door to take out the metering rods and the little teeny itty-bitty clip right over the door that needs to come off to do it...
I like the different just too much... it looked different it seemed to operate a little different and I haven't seen a lot of them so I had to have it.. it has had some Sparks of greatness and I do feel once it's tuned correctly I should be happy.
In post 1553 you can see the spring wrapped around the secondary door rod. I'm hoping that it's spring loaded shut and all I have to do is pull the pin and take that little Rod off of each one...
I really hate pumping my throttle to see the motion with the bowls full of fuel and I'm not going to start it. Just dumping fuel in there and letting it set.. from the little action that I did put on it it did look like those rods just force against the spring loaded doors to open it not to close it.. you really got a thing Edelbrock and thermoquad not Holley when you're looking at this. The only Holley thing on this is the secondary Jets and that messed up 45 degree angle down on the fuel Boss...
one clip per carb and the fuel pump rod is disconnected....
no progress today they predicted rain all day but over here just was on and off but not good enough to take the car out by a long shot. Tomorrow morning I'm going to meet and greet with a customer and then go get some oil for an oil change and give her one try in the afternoon with the secondaries disconnected and see where I'm at that way...
Whacked??? I think I'm going to have to look that one up...
You should be giving me the old two steps up here the step down there tighten the spring loosen that night hold your left ear to the butterfly twinkle your toes on the accelerator and presto everything's working absolutely perfect!!..
...
I know you like the poking the most..
Not really, it was an honest question about progress.
I appreciate that it's better than saying nothing at least it gives me food for thought and something to try..
