So I tested my new AEM 5 gallon tank out at California Speedway this weekend! It worked perfectly and just no worries of running out of METH. The tank is baffled along the bottom to reduce sloshing. I mounted the tank on rails spanning the spare tire well, still allowing for removal of the spare for track days. I recommend it to anyone who is sick of having to constantly re-fill their tiny tanks on track days or even daily driving. Except for drag cars, (5 gallons of Meth weighs @ 40 pounds...not good for weight reduction), this thing is great.
