Cal Poly Supermileage

Hello, I am a freshman electrical engineering student at California Polytechnic State University (Cal Poly SLO). I am part of an engineering club on campus called Supermileage. We compete in the yearly Shell EcoMarathon for the Americas, and last year we got 1,500 miles per gallon. This year we aim to improve that amount with a redesigned car which includes a new Power Distribution Board.

As Electrical Engineering Lead, I am in charge of redesigning our power distribution board to better suit our car. In previous years we used relays to switch the power for our board, but this year I am choosing to create a PCB with mosfets. The MOSFETs drain less power, and the PCB will replace a rats nest of wires and unnecessary weight which the old power distribution board had (pictured below) as well as reducing size. 

The new board design is below. 

The only special consideration for this board is that the starter puls up to 40 amps, so the trade with will need to be 2 oz copper to compensate for running 40 amps through the board. To take care of the inrush current when the mosfets are initially connected with the battery and the power is turned on, we are using the previous EE lead's board, an 'Anti'Spark' switch, which was sponsored by PCB ways last quarter. 

Any help with bringing this project to fruition through the fabrication of the PCB would be greatly appreciated by myself and the rest of the Supermileage team (pictured below at comp last year).
