I like this solution better than the electric assist as part of a rack since you can retrofit to more cars. Interested to see how you mount this up under the dash, assuming you need to add some extra support to counter the forces from the assist unit (tie into the pedal box/dash/firewall)? Also cool since it removes some weight from the front of the car and one less belt driven accessory. How much current does one of these pull? - wait I found it. 80A. So other than packaging, the only upgrade would be a high amp alternator it looks like.
