surge tank
« on: September 28, 2018, 07:11:10 PM »
Hi all, I'm Wayne, this is my first post on this forum. Spud gave me a pretty good description of what my surge tank needs to look like and I'm starting to seriously look around for the size fuel cell I'll need to start with. I know that I'll likely want to start with at least a gallon and a half of methanol in order to feed an Enderle Bird Catcher on Indy Cylinder heads, shaved, with about 500 inches, give or take. I typically run at about 15.5:1 compression, if I can figure out how to get the video onto the desktop from my phone I'll do so. It runs great...the problem is that I just don't have the space to fit the front mounted cell I was running in the previous full bodied car I had last. This is a tube chassis car with a little big of Plymouth Duster body left and lots of plastic bolted on. The front clip is a one piece plastic job, the clip don't quite match the year of the quarters and roof but it's close enough for drag racing. I'd always run about a four gallon cell in the Omni, and surprisingly to me anyway, there's actually less space in front of the tires in the Duster than was in the Omni! I have a very small amount of available space for a surge tank, it needs to hold 1.5 gallons in order to avoid starvation although the rear cell and pump are pretty stout. I know I'll need to have an AN12 quite low on the surge to feed the belt driven pump, 80a-1 Enderle, it'll have to be sealed up and a return line fed back to the fuel cell and the poppit returns will probably need to be "Y'd" into that return...if possible. I'm sure many of you have had a similar situation and had to build one. I can't see paying nearly 600 bux for one because it has a float with a switch that turns off your rear pump. Besides, I like making my own stuff. In this case I'll have to farm out the welding as I am only a mig welder and have no spool gun. So rather than building an anchor our of steel...I think I'll let my aluminum welding buddy do that part. I mention the expensive tanks only because their dimension works out well for me. I think it's something like, 5" deep, 8" wide and 11" tall. Before I go any further I'm going to make a box that size and make xxxx sure it'll work for us on this car but I think it will.

So, anyone who's made their own surge tank that just returns back to the cell as opposed to using a holly float bowl or an electric switch I'd love to see it, hear all about it and even hear how many different cars it got used in! LOL

This is going to be an "over the winter" project so I'll try to work like xxxx and get it done before it gets cold here in Mid Michigan...I have enough to do when it get's cold! LOL

All help would be GREATLY appreciated I'll try to get those clips on her asap. I have a little clip on youtube of the omni if you like, it is, dodgeomnidoorslammer   all one word. The Duster I have a pic or two of but only one vid with it running and the fuel injection on it.

Thanks Jeff, I would like to see a pic. I thought about building or buying, sometimes it's cheaper and better to buy something that's better than I don't make every day, one with a float. I thought I posted my little video clip yesterday...it didn't post, I'll attempt again. It could be too big or something, it was too big to get off my phone without connecting it and downloading it to my desktop.

The fact of the matter is, if I could convince my buddy of the obvious, "we can push it up and pull it back with the quad and 2 gallon cell might be big enough!" He won't do it! At least not yet...   I always liked to have a car that I could, if I had to, go to the track alone and not worry about who will push me up and pull me back. I guess I like the idea of returning the fuel to the tank and not needing a float. It may or may not be the BEST way. I think it's just a matter of "that's what I want".

Anyway, I'll post this and then attempt to post the vid again...

Wayne

Maybe I'm doing it wrong, maybe I'm not allowed to put a video in...I'm not going to keep putting them on, it said it an attachment was on but it doesn't show up. No biggie, it doesn't show that much anyway.
