For those that are not waxers
Here is a trick I have been using for many years with parking brake handle
When you want to blow someone from a stop light or staging lights at drag strip
Push the release button of handle in and while holding it in drill a small hole through the handle and button
Now when at war, push button in and slide a small rod through the case
This will prevent parking brake handle not to latch so when needed, hold the handle up and will not have to have foot on brake pedal
Bring your engine revs up to torque up ( if auto tranny set RPMs higher than the torque converter stall RPMS) the car and hold that RPM
When ready, simply release the brake handle while you're hard on the gas pedal and leave the other guy sitting there with his on his pud !
Will have great reaction and 60 foot times
