I think he was talking about unoffical record, not back up. Max'd Out had held both records pretty much since march of 2009, still has the MPH record at 148.31 mph, but there were short periods of time whenTorrey, Aaron Schaff, Jeff Dean and Brian Spooner held the ET record. There were rule changes in 2010 that knocked Max'd Out of Superstreet until Rob changed some things to comply and got the records back.
Both the current records will fall this year and by a lot, especially the ET, there are currently about 8 trucks capable of breaking them.
