We want to get a delay box so Melissa can get used to leaving off the first flash of yellow. Is this box OK? Any pitfalls or problems to look out for? Are there wiring diagrams or instructions available on the net?

It's the older thumb wheel type box. They usually work preety good, but they do have some mechanical relays inside that sometimes stick a little when they get old. When they stick they don't always release the same each time. A buddy had that problem. He sent it in for service and they repaired it cheap, sent it back and no problems since. Here is another auction for the same type.

Personally, I have been on both the "Pro" & "Con" when it comes to delay boxes. For several years I had a Dedenbear RTD-6 in my Fairmont, never had a problem with it, and was usually able to stay in the .000 to .012 RT range.When I got bored with running the automatic and delay box, I sold the delay box and C6, & bought a Jerico 4 speed, and became a bottom bulb "footbrake"(clutch) racer again, and have never had so much fun! Sure, my "packages" are not as tight as before, but when you run a class where nobody else is using boxes either, you can still have a lot of fun, without "needing" to go "double OO, and running the number dead on". Now, I have many friends that run the .90 classes, as well as electronics ET, and I can appreciate thier efforts, but I`m glad I got out of the "electronics rat race" myself. ------------------ 78 Fairmont 428 4 speed [email protected] 1.32 60 foot 80 Fairmont 302 5 speed 12.8@105mph 85 Mustang NHRA M/Stock 302 5speed.

My brother and I both use the RTD7, this is a very simple box - no crossover, bump down..... We haven't had any problems with the box other than driver error. Dedenbear has a lot of info at thier site, manuals etc.I have seen them on Ebay for $75 US - may want to keep costs down - all those other features are just yet another way to screw up! from www.dedenbear.com : RTD7 $199 NHRA accepted non-microprocessor unit.

The 2 Dedenbears look like Digital Delay units with Dedenbears name on them.Digital Delay makes most, if not all the Biondo units as well as others. DD is a Davenport, Iowa based family business started by a drag racer, Ike Hamma, who recently passed away. His family still operates the company, his brother took over as I understand. Thier reputation in our area is excellent. Of course they are 30 miles away, so that helps. The one Steve linked to looks like the one KV has. It always seemed to work fine when he was using it. BTW, a unit like that is easy to set up for quick removal. It uses 4 wires so a flat 4 wire trailer plug setup can be used. A second plug half can be wired to connect the transbrake circuit back together so the box can come out in about 30 seconds. ------------------ 63 Falcon 377 Cleveland stroker Flying Toilet alchohol injection. 6.19 @ 110 MPH 1/8 mile 2002 Ranger FX4 daily driver 2000 F350 PSD Crew cab dually - Like commuting in a B52!! 98 US Cargo Phantom II 28' [This message has been edited by Dad Vishus (edited 11-05-2005).]

LOL!!!! At the rate of automation progression, folks will soon be able to - via a joy stick and CRT screen - back their race car out of the on-track storage garage, stage it, and 'drive' it without even leaving the A/C comfort of a rented motorhome parked at the RV center! Of course, it seems we're dang close to that level of automation now - with many folks 'racing' their cars/bikes on a chassis dynometer! Sure, there's no crosswinds, no chutes, no big $ brake systems, no wheelie bars ( ), & not many wrecks on the dyno,,,,but I'd bet it doesn't give ya nearly 'The Thrill of Victory' either! But Hey --- I'm not picking on Steve & Melissa for wanting to go their desired route.... to each their own & Good Luck with it! Just for the record: I'm with Rory -- I prefer to get 'er done the old fashioned way - with good ol' foot & eye coordination! Ryan

Thanks for the info on delay boxes. This post wasn't about whether or not delay box racing was ok or manly enough. Or whether bottom bulb racing was more fun than top bulb racing. We've done the bottom bulb stuff, the clutch stuff, and my heap is a footbrake car. DV, So a four wire plug and she can go off the top or bottom bulb for only $100? Sounds like a cheap way to find out if she like it. Thanks, SteveW

Yep. It's a cheap but frustrating way to find out just how consistant those dam*ned pipe cars really are. You really dont need any instructions with the old cross-over Dedenbear. Every place a wire needs to be attached is labeled right on the box. I didn't have any instructions with either box I have, and somehow I managed to get them hooked up right (and I'm really bad at wiring).

Not consistant enough. Dang it! I've had to adjust my dial-in by .02 total over the past 3 races in 5 weeks in two different states. But, it did go 4.931-4.937 6 times in a row yesterday until a bad trans brake solenoid cost me the round at 4 cars. Steve, I've never seen that last one you posted before. Don't know anything about it. As long as you stay with the Big 3 you will do ok on a purchase and get support as well. K&R, Biondo, Dedenbear. Even though many of them have the extrasm you don't have to even hook them up. My K&R has about 8 connections, but it would work as a regular delay box with only 4 connected. 12V power, ground, transbrake/2 step output, button.

I hear ya. I got tired of being .015 and off my dial by .010 and hearing them go "whomp whomp" as they went by me. It's not impossible for a door car to be competitive, but it sure is a lot harder, especially a door car that is a non-tube chassis car. At the bracket finals after the 3rd round, I don't think there was a dozen door cars still in.

nothing new there KV... fiver years ago at a $10K race in hattiesburg, I counted 20 door cars... alot you say? There were 160 cars there for two classes. I might have mised 10 or so but they were as rare as hens teeth. us doorslammers are being pushed out of Brackets.. which is fine by me since I ain't crazy about bracket racing. Newest thing round here is Index racing on a pro tree. ------------------ JS Life`s journey is not to arrive at the grave safely in a well-perserved body, but rather to skid in sideways, totally worn out, shouting "holysh....t what a ride!!!" 69 Mustang Pro ET Drag

i always wondered what delay boxes were for. now i get the impression its some kind of electronic device that accurately and consistantly sucks the fun out of bracket racing. just like the ass with all the money does to heads up. good luck steve but it enough for me to know your car is dang fast.------------------ "back then i could throw a football a quarter mile....i bet i could throw a football over those mountains."

I don't think that having a delay box will take the fun out of racing or make a person any less of a racer. I feel that it's just another way of racing. Being opened minded and trying out different ways of competing makes a person better off. There aren't that many rails in Super Pro on the west coast and they don't scare me. *Melissa*

yeah,What she said..... Delay boxes aren't something magical that allows the car to be driven by remote control. If you react late or early you'll know, but there will be a "delay" LOL Thanks for your offer Steve Strain, that will be cool. Nice to have some MMk'r Racing support. You're one of the bestest.

Index racing has become popular around here, there are three main classes....8.0,7.0 & 6.0Run on a .400 pro tree, you're just trying to come closest to the index.....it's very hard racing IMO. So basically you just try to run the number, just like bracket racing, but both cars leave at the same time on a pro tree. I've done some 7.00 index racing and thos bracket guys will put a major hurtin on an inexpereinced guy like me.

Being opened minded and trying out different ways of competing makes a person better off. [/QUOTE]I agree. I have ran some heads up 10.90 super street stuff off a pro tree, delay box racing, footbrake racing, and no-box racing. I have won at least one race in all of them and like to consider myself a pretty good racer. (In case you were wondering, and even if you weren't, I finished 5th in points the first year I ran with the box in the car. But that was in Iowa, and there were not near as many dragsters running Top back then as there are here.) And I also think everyone should try it for a year or two. I thikn it does make you a better racer running different classes. quote: Originally posted by Melissa: There aren't that many rails in Super Pro on the west coast and they don't scare me. *Melissa*
It's not about being scared, it's about having a car that is competitive. Anybody that really knows me, knows there isn't a single racer anywhere that scares me on the track. A dragster is just so much more consistant than a non-tube chassis doorcar. The wind doesn't effect them near as much, changing track conditions don't effect them as much, and they leave exactly the same every time. That makes it much easier for them to dial the box for double oh lites every pass. Don't get me wrong, it is fun running with the box in the car. It's a different form of fun, and you will see when you do it. But winning rounds on a consistant basis is also fun, and it's easier to do that in a non electronics class (at least with my car it is.) Good luck.

im still not sure what a delay box is. i just keep skipping past those pages in my speed parts catalog. once i took the time to find out what a 2-step rev limiter was. i realized that i needed one right away. test and tune night in lanes 3&4 will always be the pinnacle for me. im still living vicariously through steve/melissa's 408 car since thats what i wouldve built if i had the money. ------------------ "back then i could throw a football a quarter mile....i bet i could throw a football over those mountains."

A delay box is just a tool. A transbrake is a tool, the correct slicks, engine, etc are just tools. The driver still has a job to do. A fun job. A delay box is simply a timer that delays the release of the tranbrake. You stage the car and set the transbrake as normal. With a non delay box car you let go of the transbrake button when you see the last of the 3 yellow bulbs come. The idea is to get the car moving so it breaks the starting line beam just as the green comes on. With a delay box you release the button at the first flash of the *first* bulb, not the third bulb. Reacting to the top bulb is more consistant than waiting on the tree to count down. The delay box adds a preset time from the time you release the button until the car launches. On a sportman tree there is is .500 sec between bulbs, so you would start with 1.000 delay. That's the time between the first and 3rd bulbs. With a faster car like mine, you have to add more time or the car will redlight. I normally run around 1.125 in mine. Anyone that thinks a delay box makes it easy is wrong. What is does is greatly tighten the competition on the starting line. It will make an average driver cut "good" lights and will make a good driver cut "great" lights. But, you still have to launch the car at the right time. As far as the dragster goes....I have a blast driving mine. Anyone that says they are boring has not driven one. When your 60' times start going below 1.0X sec and you go 0-100 in 3 secs and 0-140+ in under 5 seconds you DON'T get bored. Trust me. I run a dragster as it's the cheapest way to go FAST. It would cost me 3X the money I have in my car to go the same speed with a door car. With 2 kids in college, the mortgage, etc there is no way I could afford a 4 sec door car or the operating expense of a heads up car. The dragster is consistant because it was built that way. Everything on the car is there for speed and consistency. Purpose built tube chassis door cars can also be as consistent, but they are a little more dependent on weather changes than a dragster. I would just as soon chunk the electronics in the trash, but you can't put the genie back in the bottle. I'm stuck with them as they won't let me run my car with the non electronics cars, even I if removed the delay box. Too fast, they say. That is sort of ironic though. I have more difficulty running the slowing cars. It's very tough to judge the finish line on a car that I'm running down with a 40 mph speed difference. David Cole

Well Bracket racers say it's still the same as brackets just someone else dials your car. Heads up guys say it isnt really heads up even though you both leave at the same time on a pro tree. So I guess no body likes it, maybe that's why everyone is going to it and bracket racing is dying a slow painful death...around here anyway. I'm sure there is something inherintly wrong with it.... just can't find it yet. ------------------ JS Life`s journey is not to arrive at the grave safely in a well-perserved body, but rather to skid in sideways, totally worn out, shouting "holysh....t what a ride!!!" 69 Mustang Pro ET Drag

I personally dont like electronic aid tools in a race car. The 2 step is enough while foot braking the car. I know of some racers using a 4 wheel line lock and a 2-step off of a button just like a trans brake. Even though its not legal to do so.

Tony, If it isn't legal, then doesn't it "get caught" when they go through tech inspection? Ok, ok, so tech doesn't look THAT hard at the cars.... If someone wins while "cheating" with illegal electronics in a particular class, I wonder if they still feel proud of their victory? Do ya think the cheaters brag their win up to their kids - It probably would sound like, "We won, Son! Of course we used illegal equipment to get there, but they didn't catch us, so it's OK! I'm sure everyone else is cheating somehow just like we did!" ???? It's like fist-fighting a 100yr old dude - really something to be proud of! I wonder if those cheaters sleep good at night......

There are two classes at the tracks I run at, footbrake and Pro. Footbrake means (as it should be)NO electronics, no transbrake, no two step, no delay box. Pro, anything goes. Pro has a 7.99 and faster limit. No six second cars running a 12 sec. car. Jerry spoke of 6.0, 7.0 etc pro tree classes, they were tried and cancelled due to lack of participants at the track I run at. Headsup still runs occasionally, but I dont carry my car when they are running due to the idiots wanting to stand in the staging, burnout areas, and all that dragassing around, having someone tell them when to pull out of the water, where to stop at, turning on the nitrous, then all that damn revving up 10 15 times before they stage, takes damn near all night! Then after all that most cant even make a full pass running 1-2 sometime 3 seconds slower than the bracket cars.With thousands of dollars more invested in them than the bracket cars, you would think they would spend some on handling and chassis set up. Anyone who thinks that a box will automatically have you cutting "O"lights, just has not tried them. Even though the "leave" is controlled electrically, it STILL depends on the driver for experience and reaction time. For the first 6 months, I was ready to throw mine out the window and try to run over it, couldn't cut a light if I owned the tree, let alone be consistant at it. Just like footbraking, it takes practice, practice, practice, and then you practice some more. AND,I Still cant cut a consistant light! Bob Carr ------------------ BAD COMPANY TILL THE DAY I DIE!!!!!
