Bob, do you have a roll over valve in your fuel tank vent line? If not, the vent tube has to run past the bottom of the tank to prevent fuel coming out in the event of a rollover. The tank looks like it fits right into the theme of the car though.
That thing should fly with 300 HP. Do you know what the car/driver weighs in at? There is some talk of building a couple of similar cars to run at our local track that were inspired by showing some freinds your build thread. Have to wait and see what happens there though.
