Title: Race Tank Diagram
Post by: Balsa Butcher on February 17, 2013, 07:56:44 PM

I am looking for the SSR tank diagram/instructions that were posted awhile back, by Bill Bishop I think. I did a search and looked through the pages here but could not find it. My SSR needs more fuel capacity so I need to make a larger tank. Anyone know where it was posted?, or please post again. Thanks in advance.  8)

New tank fabricated per Bill Bischoff's instructions. Old tank capacity 1 ounce, new tank capacity 1.25 ounces, good for 40 laps at a relatively rich setting. Question: (which may seem stupid however I'll ask) I have been capping off the overflow. Is it necessary in this tank? I assume it is however removing a cap and re-installing it during a race is a mistake waiting to happen so I'm hoping to not have to do it. Thanks in advance. 8)

Capping the overflow is NOT necessary.

With this design, you will have a uniflow. Since both vent and fill tubes end against the outside edge of the tank, whichever one actually bleeds the air is immaterial.

Great! That's the answer I had hoped for. Thanks Bill...and Bill.  8)

Per Bills instructions: All the tubes stop just inside the tank where they are installed. Details on the "SSR Nearing Completion" post. Works great! 8)

These tanks have a tendency to richen up a bit during the run, I presume when the upper uniflow vent is uncovered.  It is not really noticeable with a full lean race setting, but if it is a little rich it is more noticeable.  Of course, running a sewer-pipe venturi might have something to do with it.
