[DeTomaso] Cranking amps

[Joseph F. Byrd, Jr.]

If you know your starter's motor size, you can get the max amp draw by dividing by voltage
Example a 1.8KW starter will draw (1,800/12)= 150 amps at first and as the battery voltage drops (1,800/10)=180 amps

Hi:
I read the posts regarding the amount of cranking amps required to turn a
V-8 but all the responses were about the capability of the battery to supply the current, but none addressed my question.

However, I did a little more digging and this is what I found out:
http://www.linnbenton.edu/auto/fall/electric/start_test.pdf

Tests from this automobile college class experimentation lead to the
following:

"8 cylinder gas -typically draws up to 250 amps."

The college test also considered cold-started engines as well as overheated engines as likely drawing more current that what was discussed.

Thanks again,
