Regarding the mention above about El Mirage events, yes there are six events scheduled each season. The El Mirage events are organized by the SCTA, same as Bonneville. The layout is similar to Bonneville Speedweek except there are no record runs (second run which provides the the run average, the average must exceed the existing record). One difference is the distance of each run, El Mirage is 1.3 miles in length, Bonneville is 3 or 5 miles in length. And of course the surfaces are very different, dirt for El Mirage and salt for Bonneville.
Attached is a picture of the car we campaign at El Mirage and Bonneville, a 1985 Dodge Shelby Charger. It is powered by a 2.0L turbocharged 16 valve four cylinder motor. No records at Bonneville (that place is rough on cars!), but 5 records at El Mirage, the last was 193.789 mph.
