Yeah I worded that wrong... I used a 3.5 gallon tank that is mounted in the trunk. The tank was custom built to my specs by Stef's (see link below). I chose one of their standard dirt track tanks (part No. 4155) and had them modify it. They sent me a drawing of the stock tank and then I marked up the drawing and changed the width slightly so I could get 3.5 gallons. My tank holds 3.5 gallons when half full.
The tanks are very well made and engineered correctly with special internal baffles and plates designed to deaerate the oil. A.C. Nutter (my engine builder) helped me to size the tank. He has lots of experience with dry sump systems and he said to use a 3 to 4 gallon tank minimum if it's mounted in the trunk. The advantage to running larger tanks is that the oil has more time to deareate before getting pumped back into the engine.
I have had good results with this set up. I installed a 4 stage dry sump pump, plumbing, and tank set up in the car last August and have run the car on the street since then, and one HPDE track day last September with no oiling problems. My oil pressure is about 40 psi at idle and 60 psi when cruising.
Here are some pics of the set up
About $140 worth of oil for one oil change!
I'll post more on the whole set up later... I just wanted to get you the info on the tank. Here is the link to their website... I worked with Stan:

I started with tank #4155 under "custom dry sump tank assemblies". Stef'sdoes the custom tanks all the time... very good guys to work with. I decide to mount the tank in the trunk so I could keep things cleaner looking under the hood and I wanted to keep the battery, ECM, and fuel pump controller up in the right front of the car for easy access and better cooling.
