Energy Storage (Battery vrs Capacitors)

I think the key is (when you turn the key

) the number of times you can crank the engine over using a battery vrs capacitor. I think your voltage will drop very quickly using capacitors and as you know........trying to start the LT5 with low voltage just does not work so well

In the video....that car started every time on the first or second rotation of the crankshaft. Now sit on the starter a bit cranking a few times and watch that capacitor voltage drop. Then after the Capacitor voltage has dropped.....try starting the LT5 and see what happens. Time to pull out the ZR-1 Tow Adapter.....

Or (after the capacitor voltage has dropped on just a few cranks (crankshaft rotations during starting)) jump the capacitors to a battery which you could probably do many times before the battery voltage drops nearly as much as the capacitor voltage dropped on just a few cranks of the LT5
