Re: David85's saturn SL1 conversion
I'm hoping for another week unless something else comes up. Still have to finish modifying the motor controller and mount it in the car, then I have to build/install the last battery box. Once the structural stuff is all installed, then I have to wire everything up (main cables, AND battery balancer harness).
Still waiting on some parts in the mail, but I hope to see them in another few days (vacuum brake stuff and DC/DC converter to run the 12V systems).
There will still be a ton of things left to do at that point, but the car can be driven under its own power even if just for a few miles. I'm certainly NOT going to miss pushing this car around!

Re: David85's saturn SL1 conversion
MOTOR CONTROLLER IS IN!!!!!!!!!!!   
I had to trim down the cooling fins and make a different cover for the cooling fans, but it was worth it. The controller is nicely tucked under the hood (instead of having to put it in the trunk), and it looks ok too. I would guess there will be less than a quarter inch clearance between the controller and the hood when its done. I managed to trim over an inch off the package size. With some imagination it could be converted to liquid cooling and eliminate the cooling fins completely. For all I know that is optional from the manufacturer.
Right now its only resting on the transmission bell housing and has a support on the other side. Once I have the final battery box made, the controller will bolt into that instead of having redundant bracketry for the two assemblies.

Re: David85's saturn SL1 conversion
Final battery box 80% complete.
I threw in some close ups on the wields that I did. Anyone that is familiar with wielding sheet or auto body will recognize the method I am using. So far no warping. Its taken a while but I finally got the hang of wielding these boxes up. This is without a doubt the tightest box I built so far.

Re: David85's saturn SL1 conversion
Now for how it will fit in the car. There is about 1" of clearance to the hood, but I might decide to take much of that up to make sure the box doesn't knock against the motor underneath. Lid still has to be made, and there is a small piece missing but since I ran out of steam I dropped it in and took some shots then came in to warm up.

Nice and clean looking. Looks better than a factory job. Keep up the good work.
