Enderle Birdcatcher(Advice)

I'm getting this injection setup ready to go on. I've got the intake about ready,throttle linkage and plumbing are done. What I'm going to try to do is insert this 3/8 tubing into the front of the top plate under the Birdcatcher and drill a hole over each intake runner. I'm going to use pump gas to start this thing and hopefully get it to idle around 1500 to 1600 RPM on it. I want to start it, warm it up, and drive it to the the line on this and then open the fuel shut off and let the alky take over. I saw a guy who had a similar set on a dragster at Norwalk and he said it was great. Does anyone have a clue as to what size holes I might need to drill in this tubing(spraybar) to idle around there??[img][/img][img][/img][img][/img]

I'm not sure of the size of holes, but you will need a valve to adjust the fuel going to the tube.
The holes need to be facing up.
The tube needs to have a jet at the entry point.

Dan,

Here are some pics of my plate style primer. I can idle around the pits and back up the return road on pump gas. It's from James Monroe at Killer Ron's. It has 6 tiny holes. I would guess around .025-.030 or so. The holes point up at about 45° for better fuel distribution and a fine mist. As Curt mentioned, you need a jet (up's the pressure). Mine is a #38 Ron's jet. The needle valve let's you fine tune it so you can drive it around. You can buy the same valve I have from McMaster Carr.

Thanks David and Curt. I think you guys just saved me a few headaches here. I'll get it lined out ,just nice to have your help and ideas. They are greatly appreciated!!

David ,how is your gas fuel delivery set up to the valve? I'm sure you have a pump ,but are you regulating it before the needle valve? Thanks, Dan-O

Dan, we use a small electric pump that pressures up against the needle valve.

Dan,

I use one of the "Facet Fuel Pump" that Curt mentioned. These are the little cube shaped pumps you can get at most parts stores for ~$35. They put out about 4.5-6 psi, and no regulator is needed. You also need a nitrous gas solenoid. Wire the solenoid so it's on/open when the pump is on. Without it, the engine will siphon fuel through the system after you turn the pump off.

For fuel line -3 hose works great. I needed to extend the hose that came with mine and just used premade braided brake hose.

Here is a pic from when I was building my dragster, you can see the pump, solenoid and bottom of the 1 qt fuel tank. BTW, I can make two round trips to staging and back up the return road on 1 qt of gas.

Oh yeah, and a little nitrous gas solenoid.

Dont use a nos or nos gas sol, they will burn up with the continuoues operation. Ron's sells them, James Monroe can get the seperate. as for the pump the little cheapo pumps from the parts stors works fine. David has you set on the bar setup, needle valve and jet.

I'm wanting to use my cell in the back for the gas . I thought I'd switch pumps on my mustang and put the BG280 on here with the regulator since I already have it all in place. I think that old 280 pump is about wore out (low on pressure)I may just get a cheap pump though?Thanks for all the advice.I think I'm headed the right way now.

The big pump wont work, use the small Facet (sp) pump. No need for a cell any bigger than a quart or so unless you just want the weight.

I want to leave the cell ,so I can just fill it up and run all weekend on it.I'll neck it down and put a small pump on it. I just don't want to fill it up every couple of passes ...unless I have to.I'm starting to think that maybe a 1 gallon cell up front may be the ticket. I'm trying to do this on the cheap side.

I just saw a 25 GPH pump on ebay for $18 . I don't think a rubber line is NHRA legal is it?

Slide some of that braid over it,

you can run a short amount, besides who evens techs anymore lol, am considering not reneming my license as Ive never been asked for it.

If your going to run Unleashed you'll have to pass tech and have your credentials all in line....I'll have to be legal for the Hotrod Reunion is why I'm wondering.You won't get by the Safety Safari if your stuff ain't right. It won't be the local track making the call when they come to town.

I'll need to update my ultrabell anyway..................june is a ways off, I'm sure I'll renew it by then lol...................but that would be the only race I would do it for...................may take the slow car anyways............

if the Grandy ant running its the slow car

My Stuff Runs........and is still slow.. lol

We got the "black car" (grande') and the "slow car" or "brown turd"................the slow car only run 10.30's....but compared to the black one its a turtle lol.

I've been using a gasoline primer under my hat for years.
Use Rons "unvented" injector nozzles with 34 jets in them.
If you use a Holley Blue pump you can even drive around
on it (be gentle tho). Also be sure to run a solenoid (&
filter) inline so it doesnt siphon when off.
