    A thought on fuel tanks

    My 318is with an S50 engine has trouble leaning out on right turns unless I keep the fuel tank fairly full. I'm thinking of cutting out the driver's side of the tank, and then blocking the opening between the two sides, so that it becomes a 6 gallon tank on the passenger side. I will leave the frame work intact so that the stock mounting hardware is still used, but the body of the drivers side tank will be gone.

    'Think that will solve my problem?

    Interesting idea. I have the same problem, but plan on using a surge tank to fix it. Your solution is cheaper, but you lose half your capacity. If you just autox and don't drive to events it probably isn't much of an issue, however if you do drive places stopping every 120 miles for gas or topping off after every track session would get annoying pretty quickly (for me anyway).

      This was the first thing that came to my mind as well.

        I tried driving it to an event once. The seat is way too uncomfortable, and the drone of the exhaust will drive you nuts. Earplugs don't work on low frequencies. Also, the car tends to be a cop magnet. Last time I drove it on the street, I didn't get a half a mile before I was pulled over. For these reasons, I usually trailer the car to an event.

          The solution is to convert to a hybrid fuel system. Run an early transfer pump on the left side to feed a late model high pressure pump on the right side. This is fairly documented in the track section.

            Cops in your area must be asses, I drive mine to the track all the time.. Sometimes, I even remember to cover the numbers up before I leave.
