Jim,

The Pentad motor is a Scotts motor that has been tweaked on and had the label changed. The efficiency is no place close to the Etec motor. A few years ago everyone was running either a Scotts or Pentads, now almost every motor is an Etec. It is one is the primary reasons why most people now finish Electrathons instead of going dead, short of the one hour mark.

So, bottom line is: If the team won with a Pentad, they could have likely added a lap or two more with an Etec.
