We had 4 CIMs and 2 Mini CIMs, geared at 5.95:1 on a AM14U with 4" wheels.
Before our regional, we ran out of 6AWG wire, and the local supplier only had 8AWG. So for around a week we ran with 8AWG and a 70A breaker. During high acceleration/deceleration or turning, with the compressor running, we did actually trip the 70A breaker a few times.
However, when we got to Hawaii (with the correct wire and breaker) we got in a number of pushing matches against teams with shifters or 6 CIMS, but we never tripped the 120A breaker.
I should note that the 70A breaker wasn't up to the same quality of the coper busman ones we have in the KoP (felt light and cheap), I suspect that it was tripping on 70A of instantaneous current, while the 120A breaker will handle 120A for quite some time. I know this is a crude measure of current draw, but it is one none the less.
Hopefully that's useful
