Stock Eliminator class is very restrictive, you must use stock parts, and you must tear apart your engine for inspection after setting records, after winning races, or at any time your performance is good enough to draw attention. The better your time, the more weight you must carry as a penalty to keep the class competitive. Otherwise, there would be one fastest car that cost a million dollars LOL. The only exception to this rule is when you meet another car in the same Stock Eliminator class as yourself, for example, two L/SA cars are racing each other, then, it is flat out and the fastest car should win if nothing bad happens. You never want to tip your hand and show how fast you can go; you never want to take a record by alot. That would bring heat on your car. My car picture here ran J/K/L/M in automatic and stick. Usually, I ran L/SA and would go about 12.00 @110. The car was actually able to turn 10.90's but of course I would never want to show that! Of course any car can go faster simply by losing weight, but in NHRA you have to be weighed, have your gas tested, and tear down the engine. That is the hard part...and the credit and expertise goes to my ex-husband, Mark Yacavone.
