Re: take all the numbers off of the time slips, lol
Come on Michael, problems with the timing system? That can't happen, can it? ;) I don;t think enough people realize how many times it "really" happens.

Re: take all the numbers off of the time slips, lol
Bill,
Using a delay box on a footbrake car just requires installing a second line-loc into the rear brakes and a two-step. I put on on my Stocker about mid-year in 1988 when they were legal but had some inconsistency issues. Replacing the solid-core plug wires with carbon type and killing the field on the altenator solved the problem. Unfortunately I didn't get it sorted out until after the Keystone Nationals and delay boxes were outlawed in 1989. Mr. Muncy was caught because motion was detected in his arm and shoulder but I believe it can be successfully operated undetected with the left foot. I'm sure people smarter than me has already figured this out. Danny |

As another example, take my Volare with a 1.45 60', Terry Knott's Dart Sport with a 1.50 60', and my Duster bracket car with a 1.60 60'. Terry's car reacts the fastest of the three, followed by the Duster, and the "quickest" of the cars, the Volare, reacting the slowest. With the SS/CM car I referred to earlier, the slow transbrake, long button, and much larger tire (more slick wrinkle), had the same rollout as Terry's Dart. I've also driven a SS/BX car, which was the 3rd quickest car I've driven, yet it was the fastest-reacting car I've driven, by a TON. A lot of things happen that effect reaction time *before* the car physically starts moving forward. John D -- My "favorite" timing system error I've seen is one where it gives the correct incremental times, correct MPH, yet trips the finish line with the BACK tire. I saw this happen about four times in one day. We could fill a whole separate thread with timing system "nuances". |

John Kelley, Question who purchased both of Ron Muncy cars? I don`t think they found the delay system on Ron car? Wesley asked Ron if he had a delay system and he said yes, and went home and sold his cars, That`s the way i heard the story. Tom

Bill asked how a line-loc could be used to effect a delay box for a starting-line advantage. Danny Ashley replied: "Bill, Using a delay box on a footbrake car just requires installing a second line-loc into the rear brakes and a two-step.

I understand all of it except, I am at a loss to understand the relationship between a line-loc and solid-core sparkplug wires and an alternator's output. Can you give me the reasons for those relationships, please? Is it some sort of "R-F" interference generated by the magnetic fields, and if it is, by what method do they interfere with, or affect, a purely electrical solenoid like is in a line-loc???? Or, was it the two-step that was affected? I have taken videos of cars that had two--steps that played havoc with my video-recorder while the two-step was in operation. I am baffled by this one! Thanks for any info, Bill |

The Radio Frequency Interference (RFI) generated by an alternator &/or an ignition system can disrupt the tiny electrical signals in an electronic device like a delay box. Each little trace on the circuit board can act as an antenna, which results in an unwanted electrical current in that circuit, which can in turn "crash" the microprocessor, or at least scramble some of its results. I built my own microprocessor controlled delay box in the late 80's, and in the original plastic enclosure it would crap out as soon as I started the car. Moved it into a metal enclosure and it worked fine. Regards, |
