PMS Marketing Clip Of The Day. 1999 ATPA Monroe, MI Grand American Duane Bergman Rambunctious 2. This week's mandatory Allison clip is from 1999 and bit of a wild ride for Duane. It seems that the steering broke after the hard hit and one of the two V12s stopped participating at that point as well. Note the frame twist at the front in the opposite direction. That is a right hand rotation motor. These were paired in the P-38 fighters and would spin in opposite directions to cancel torque. Duane would finish 5th in the 1999 GA modified points. Once of the few Top 5 finishes for an Allison in the last 25 years.
