I am not sure what all went down exactly. I backed the car up in the driveway so i would have a bit of room, never trusting things will go perfect . I was right! I was trying to test the airshifter , which i put on an MSD shift light circuit. i had the rpm set at 3200 so i could get it to shift and still hold the car, or if it moved, stop it. After backing up i let go of the transbrake button and the car launched like the throttle was wide open. When the transbrake is activated, an ACD throttle controller colapses to my preset launch setting. Either my foot got in the way, or the throttle stuck, and away we went! I had my foot on the brakes hard, but that is no mach for almost a 1,000 hp!. I reached over and took a swipe at my switch panel, and hit the ignition switch off. I got it stopped about ten feet from the garage and trailer! All i can say is i say a prayer every time i get in that car, and I believe I got help!!!!!

Wow, that could have been way worse! Glad you got it shut down and didn't tear up anything!

The marks show the front wheels never turned a lick! and the slope actually steered the car away from that big pine on the left! Kinda like it threaded a needle! Future tests will be on jackstands, with enough room for tire growth!

You know, they make a msd ignition tester that will allow you to test all rpm "stuff" without starting the car.
Without Data, you’re just another guy with an opinion.

Yes they sell one and the newer version even allow you to simulate an entire run. It also is the only one that works with a grid, and its cheaper. Now figure out why the throttle hung open, get a tester as it can save you time, fuel and issuse and get to the track before it freezes again You want this one... https://proshop.summitracing.com/parts/msd-89981

So it is on the way At $392 I hope it covers my issue! I did test the throttle stop/ transvrake sequence several times without a hicup. No issues, and plenty of clearance around the components. So i suspect it was due to the wrong shoes and my big feet,! rest assured, this lesson will not be forgotten.

The older testers will NOT work with a grid. BUt I have one of those in the trailer as well still.
