Doing some reading:
400F = 0.3 amp hours
My starter is rated 83 amps, though I know realistically it peaks much higher for a brief time.
0.3 amp hours is 1080 amp seconds, or good for supplyimg 83a for 13 seconds. However, after 6.5 seconds, it would be down to ~7 volts.
This doesn't take into account that caps in a series have less capacitance.
1 / C total = 1 / C1 + C2 + ... C6
1 / C = (1 / 400) x 6, C = ~67 Farads
So, with 6x 400F caps in series I'll have an effective capacitance of 66F. I should be able to run my starter for 1.2 seconds before the caps hit 7v, and 2.4 seconds before they're completely empty.
We'll see how it goes. I'll report back with how well it starts the car in reality.
