2010 LSX Shootout This year St Louis was home of the LSX Shootout, where the fastest LS based cars in the world come to show what they've got. We are proud to say our very own Chris Fowler placed second in the ERL Performance LSX All Motor class. With the fastest qualifying round time of 9.226 at 146.97 Chris was sure to make a statement in the class. Chris sent Michelle Skyy back to Texas in the opening round with a 9.474 to 10.393 count. Chris advanced to the finals with a 9.40 when opponent John Ventrecca broke at the starting line. Judson Massingill earned the All Motor trophy with a 8.928 over Chris and his 9.307 pass in the other lane. Great job Chris!!!
