I'm sure your a better driver than I and I can't adjust my leave by a hair and to be honest with you I don't think you can either but that all aside do the math a lighter car that leaves harder will ALWAYS move quicker and that includes the first 8 inches . You are right if you adjust a box 1 time it will be close anywhere and will not take much adjustment but sometimes you only get 1 hit at the tree and if your red and don't know how red it would still help the guy not using the box some and if you don't think some of this is going on well I can find you a bridge worth the money . Have a nice day

Pretty sure he can, Ed. I know a young guy over here that can do it. He gets alot of practice though. Every time there's money up for grabs , he's there with two cars. Makes a big difference.

Wasn't it Travis Miller D3 & Wesley Roberson D4 that each found cars with delay devices in classes where they were prohibited?

You must mean the guy that got BUSTED at Ennis on April 20,2002 because the Emmon's Boys were paying attention !!!
26 4981 K/SA Ron Muncy, Weatherford TX, '79 Malibu 12.461 12.95 -0.489

And wasn't on the final qualifying sheet.....and has never returned.....

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.

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

That is incorrect, due to a huge number of variables not taken account for -- some of which I noted in my earlier post. As just a for-instance, a Super Gas car reacts as fast as a Pro Stock car. Top Fuel cars don't react very fast at all, due to the clutch and massive tire wrap-up.

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

As I remember he showed Tech the unit and told them how it worked
I don't remember who bought the stocker but it was around later on with another driver.

Bill asked how a line-loc could be used to effect a delay box for a starting-line advantage.

Thanks for that very educational explanation, Danny! 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

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.
