I was just notified about some unfactual information posted on this site about our product in December of last year. The D.U.I.-Davis Unified Ignition, which we make,is a quality distributor. First, having the module inside the distributor does not subject it to excessive heat. Silicone grease is placed under the module and the grease transfers the heat to the distributor housing. The entire distributor housing becomes the heat sinc. Also, having the ignition coil inside the cap is the best design for an ignition system because any time you mount a coil outside your distributor, you have to run a coil wire to it-this creates an additional path of resistance which your spark has to travel, dampening its effect at the plug. We utilize heavy duty rotors and caps, eliminating any possibility of arcing. The coil-in-the cap is encapsulated with thermal epoxy, one of the best heat dissipators ever developed. These are the facts about our HEI style D.U.I. distributors.

Whatever you say, but I've worked on too many GM HEI units {which is what your system is, essentially} to consider them anything but junk. Perhaps you can do miracles with them, who knows. With all due respect, you couldn't give me one of your products for free.Tony, here's a couple of threads of what he's probably talking about: https://mustangsandmore.com/ubb/Forum12/HTML/006950.html https://mustangsandmore.com/ubb/Forum12/HTML/004853.html ------------------

Also, the distributor does become the heat sink {which is what I assume you meant to say}, but the distributor itself is bolted to the engine, a very effective heat source. Most GM guys I know keep a spare HEI distributor in their trunks. ------------------

I stand by my opinion, so you can stop emailing me.  I'm not asnwering you, I don't feel it is worth my effort.And I second what Steve said, I wouldn't take one of your distributors if you gave it to me.

Sorry you feel that way guys. We have been building quality HEI style distributors since the mid '70's. Came out with the Ford DUI in about '93. Has been very successful for us and our customers.P.S.-Can be spelled heatsink or heatsinc.

America is all about free enterprise.
It's a wonderful thing.  So is choice.  HEI units are a nice easy cheap way to produce electronic ignitions for the street rod crowd. Brand new Pro Form chebbie units are advertised everywhere for under $100.
So in saying that, everything has a spot or place.
Just not in mine or anything I touch. HEI systems had (and still do) an exceptionally high failure rate. GM recognized that and discontinued the units. In the course of a racing season I come in contact with several thousand fans, racers, and enthusiasts. Many ask me about our ignitions systems and for recomendations.
I generally give them willingly if we are not too busy. I always try to recomend something that will
A) Work well and be trouble free
B) fit their application and budget. Unfortunately, an HEI unit fullfils only one of these points. In the course of a season we manage to set a record or two. While tearing down for verification of these records, we come in contact with other record setters.
Funny how over the last 20 years or so we have NEVER encountered a record setting race car regardless of make, that utilized and HEI ignition. I wish you continued success in your business, but don't feel that an endorsment will ever come from these pages. IN the car business there is a widely used expression. "there's an a$$ for every seat" That expression also applies to the aftermarket parts business I'm sure. Peace

I seen a shop install a DUI in a 1966 Stang.To me seeing a Chevy cap (Red no less) when ya open the hood is, I don't know the thing is Big... Ugly to me. Then after they installed it they tried to put the customers air cleaner back on... not! Wouldn't fit. The dist sets to high and interfers. Then shop owner had to go to a plumbing supply shop and get some PCV pipe to make a spacer for the air cleaner. The spacer was made but when they tried to close the hood.... a need for a lower air filter. All of that monkey business when a Duraspark and wide fire cap works great. Where I work our shop installs petronx modules, cap adapt, wide fire cap, 8mm wires and a good coil. Your down the road. For me it's MSD box, Duraspark dist and a little tweeking the (recurved) dist which is easy to do. My2c,

i hate to come off as mean, but why are you posting here? just because one or a few people don't have problems with them doesn't make up for bad design problems.Most of us here wouldn't run a DUI if it was given to us, and that won't change no matter how many times you post, or how many articles you can referance in your posts. Especially when it is used not because it performs well, but because it can be hooked up with one wire picked because the builder has "wiring dyslexia".... DUI may have it's place, but we don't think it belongs in our cars. End of story [This message has been edited by Dubz (edited 04-09-2004).]

TennSS,
Perhaps a better position for you to take would be to try to find out what problems actually occured with members here and try to resolve them. What is you warranty BTW?
Unlike some here, I have never had a problem with an HEI on GM products, and it got really hot under the hood of my 500 inch Eldorado. However I don't doubt their experiences. Are you guys sure it is heat and not a combination of harsh winters and hot summers that slowly break down the module?
I DO know people who run the DUI on fords and like them also.
MAybe you should send me a 351C version W/vacuum and I can report if it is better than my Unilite/MSD combo.....

Same here. If it's so much better than the seemingly seuperior MSD, then why does no one with a fast car run one? As for Vizard's article, it's well known fact he gets stuff for free in hopes he will endorse it. Try again to impress us. So far you have failed and succeeded in proving to no one how your product fits our needs; reliability with great power potential.
In case you haven't noticed, this is a RACING forum, not a street rod forum.

Over the years I'll bet that I have curved and spun over 1000 HEI distributors on my Sun distributor machine. I changed modules to Accel, and other brands and always the same results. They spark chattered over 6000 RPM. They worked ok on low rpm Buick, Pontiac, and Olds street engines, but anytime we tried to use one on a SBC or BBC that could see the other side of 6k they would pop and fart. Hell, we had OTS Mallory Rev-Pol dual point distributors that worked great to 8k.
As I stated previously, they may have their place in the industry, but not in a race car.
Peace. ------------------

Moneymaker: I agree with you that stock HEIs do falter at 5500-6000 rpms! However, we have designed the DUI electronics(module and coil) for high rpm use. The Street/Strip version fires to 7000 rpm and the Racing version to 9000 rpms. We can also calibrate the mechanical advance for top end stabiltity or simply lock it out, depending on what the race wants. Another option that many customers like is our Instant Timing Knob(ITK).

My opinion. D U I Driving under the influence.Never use anything GM on a Ford and keep your GM car all motorcraft. If you feel you have a superior product compared to MSD, Crane, Mallory, Accel and so on. Put up or shut up. Box em up and send em out for a real world test. ------------------

I ran into alot of problem {with the GM HEI units, not yours} of heat related failures. Module failures were common, {adequate silcone gel was used}, and I saw lots of examples of the rotors melting through and the center electrode arc through to the advance plates. On many of these the pivot pins would rust away and the holes in the advance weights would eggshape. Another problem was carbon tracking inside the caps, which I'd cure by spraying the insides of the caps with silicone spray. Have you cured all these problems with the units? I remember when the HEI systems came out, I went to all these GM seminars on how the HEI was the best thing since sliced bread, then the TSBs started coming out and my TSB binder wouldn't fit in it's drawer anymore. Finally, to be totally honest with you, if you have cured all of these HEI maladies I still can't get past the problem of seeing a GM designed distributor on a Ford engine. It's like looking over a nice '32 Ford then getting to the front and seeing that 350/350 combo...  ------------------

SteveLaRiviere: Module reliability is dependent on the quality of the electronics used(this is also true of CD systems). There are some brand of modules I would not use just as some CD spark box ignitions are higher quality than other brands. We used high quality caps and rotors(and nylon rotor hold-down screws)that prevent rotor melting and arcing. We also use large diameter weight pin posts instead of the plastic bushings that GM used. This prevents eggshaped holes in the advance weights. One bad problem GM had was recommending too big a plug gap in the early years of the HEI. They were using a .060" plug gap and this stressed the stock coil and module too much, burning out rotors, etc. They eventually lowered the plug gap setting to .045". You have to have a coil and module that are strong enough to jump a larger gap successfully. Yes-I believe we have cured all the problems you mentioned. I relaized that some Ford guys do not want a GM appearing distributor in their cars. It is for this reason that we also offer Ford Duraspark Performance Distributors-stock units that are custom curved. They are all on our website. By the way, are your pictured on this site?

I still remember testing early new modules by placing them in a freezer before installing them to aviod a come back.
Remember those days Steve?
As recently as last year I took an new Accel HEI module and performed a freezer test and it failed. 
You may say that we don't race in Antarctica and you would be right, but the point was that on all the steet and strip dual duty cars I used to service and curve HEI's for, failure as almost always assured in extreme heat or cold.Mr. TennSS, we too used high output aftermarket coils and modules on HEI distributors. The best that were available.
We were involved with a lot of "sportsman" stock car racing in the early 80's that required OE ignition systems as part of the rules. I built a lot of very fast chebbies (although my FoMoCo motors in Jeff Elders cars won the championships) and had to tailor them to work below 6k.
NOTHING I could come up with would sustain any prolonged high RPM spark demand.
We eventually just converted over to Corvette dual point units and lived happily ever after well into the 7k RPM working range. ------------------

Remember those days Steve?
I don't remember the freezer thing, but I remember them telling us we were using not enough silicone gel, then we were using too much, then we were supposed to clean them with alcohol before installation, then we would use the silicone gel under the rotors which seemed to help. Those nylon bushings on the advance weight pins helped, the early naked ones were a disaster. At least I got to eat a lot of Chinese food at the seminars because of those HEI units. Between those and the X-body seminars I really packed on the pounds. ------------------

SteveLaRiviere: We have a very low failure rate. The Ford DUI(HEI) has been out since around '93. We try to do all of our home work before we release a product to the consumer because it saves us and the customers time and trouble. As a businessman, I don't want the headaches of comebacks/product problems. Do your research thoroughly first.

Send one to Alex and have him test it out on a build and post the results. I am sure he would send it back to you when he is done. I would love to see it tested on a high RPM motor. Until this is done you can ALL talk til your blue in the face and it wont mean *hit. You can try to make believers for your product but until someone with Alexs knowledge tests it on a Ford engine that turns 6K plus you are waisting your time. I would love to see the test and if you are very confident with the product you should have no problem having Alex test one. I am sure he would give an HONEST descreption of what he was evaluating. Who knows he may actually like it, write something good on it and Increase your sales. You dont have anything to lose but 1 unit. If the tests came back good I would look into one for a street engine that could be modified later into race applications. If not, it is a waste of money because you will end up spending double by having to buy 2 ignition systems if you EVER plan on turning over 6K.[This message has been edited by 73torinoqcode (edited 04-09-2004).]

AHHH Must have missed that. Thinking on the same line though One unit to possibly sell hundreds more?? Makes sense to me but what do I know  If it works and it can save me money, Why Not? I am always open for something different, but need to see it in Black and White first tested by a REAL person not a magazine writer which gets paid by supliers. I might not know much with motors or the physics of ignition systems but I sure know how I spend my money.

Thats what this site is all about. Really give some thought to sending a unit to Alex and Tony. Let them test it, if it works I know for sure you'll sell enough to more then make up for alittle costs now. Like the others have said I too like to hear from guys that use the products. In the cars they drive and race. Not from someone that writes for a car rag. ------------------

He knows Alex calls it like he see's it and he knows his stuff can't hold a candle to a properly set up MSD system. He knows his distributor will come up double digit HP short of the MSD on the dyno. An dif it's not on the dyno, it will be at least a tenth slower on the track. After all, Alex does currently hold at least two National Records in super stock and has his combo sorted out real well. If you wont send him one to prove us all wrong, then I think it's time for you to spread your propoganda elsewhere. Buh-bye.

KV, I totally agree. Forget the debating. The offer was on the table, and you said no. Take your HEI or DUI or DMF or whatever you want to call it and take a hike. Proof is in the pudding. You have no proof on this forum. You call us biased. Yep thats correct. Biased to what we know will work and work at an exceptional level. This isnt from talking to people or reading magazine articles. This is from real world, on track knowledge. Until you and your company are willing to allow ANYONE no matter who it is to do a test for this forum, as far as Im concerned you have no buisness being here trying to promote your products. You can defend it until you are blue in the face as was said earlier. But No guts, no glory here. As dad would say, I never met a magazine mechanic that I liked....... ------------------

Gentlemen, in a recent independent dyno test conducted at SLP Engineering, they gained 14 more HP over an MSD system with our BB Dodge DUI. Granted, it was performed on a BB Mopar, but we use the same coil, module, and advance system on it as we do the Fords. I believe it is written up in the June issue of Mopar Muscle-my copy is at work-I'll give you the complete results early next week.

Yeah, I bet those tests weren't skewed at all. If that's really the case, then why are you afraid to send one to Alex? He may be biased, but he's not a liar, unlike ragazine's that are paid endorsements for certain products.

TennSSIf your poor excuse is "we have MSD sponsorship and we are biased" for not allowing Us specifically to test and do a write up on 1 of your units, thats fine. You have 2 others on here who said they would gladly do the same thing. Its called testing. We dont use the best stuff out there just because it fell in our lap. We have tried products and sent them back because they didnt work.
Dyno vs Real world doesnt mean a damn thing. You dont race a Dyno do you? I know we dont. This is an argument that cant be won from your end no matter what magazine information you drag into it. If you can agree to real world testing by SOMEONE other than your own people, you will get some honest results that are unbiased and very real world. If there IS a problem, then you can learn it and get it corrected. As far as IM concerned, you already have too much publicity on this thing here. I think you owe a membership fee or something.

We are not sponsored by MSD. We pay for our MSD products. I have a choice and I choose to use what I know performs. MSD performs!
Your product does not perform to the same standards as MSD does sir!
Vizzard would endorse anything he gets for free and fits his literary agenda. I can't say that I blame him for that either.A man has to make a living.
I have installed 2 DUI units. Both failed and both times (I have mentioned this before)
I was treated poorly by the DUI tech department. I am not an idiot nor did I deserve to be treated like one. The condesending attitude I receive was uncalled for and unprofessional!
Especially to someone in the trade. I would just as soon leave that piece of crap hanging on our wall of shame then send it back to you for inspection. I should have been right the first time. End of that story.
As far as installing a DUI in one of my record holding race cars.......
Had the offer been made I would have declined as
a)I have zero faith in the product
b)The unit would not fit with my custom SS or EFI intake manifold(s)
c)As stated previously, of the thousands of hard working IHRA and NHRA record holders, none have ever chosen to use the DUI product.
We have spoken of it many times during bench racing sessions and many others have indeed done testing both on track and the dyno with poor HP or reliability results.
There was an ignition company by the name of Lucas who produced ignitions systems for some of the worlds most famous cars. British Leyland, Jaguar, Austin, Triumph, MG, etc.
It was junk! Ask any british car enthusiast or technician. Guess what? That didn't stop them from continuing to produce more junk. LOL
The stuff was so failure prone that the race team mangers and engineers were at wits end.
What did the factory racing teams do?
They quietly found a reliable alternative ignition product and used it. Marreli.
They never told the factory brass about it until it didn't make any difference.
True story. (a few of you know that I am a British classic sports car buff)
Moral of the story once again, that there is a market for almost anything automotive. JC Whitney made a fortune on that premise.
That does not mean that a particular product will suit the needs of the masses as well as another. Mr. TenSS, I really enjoyed you coming on M&M and participating in your product discussion and would just as soon you don't go away mad or angry. Consider this as one lost battle.
We still have a substantial amount of members who probably use or will buy your product for their street/show cars or rods.
Better to maybe take this one on the cuff and look at the broader picture. Why piss off several thousand potential customers?
We (I) do appreciate your expertise and insight so feel free to hang around and join uis for some fun from time to time.
We're not about bashing on M&M you know.
We're about Mustangs, Fords, and Fun! Peace.

A freind of mine has a DUI on his 5.0 crate motor in a early Bronco. He swears it's great, and the ignition wires are very tough. I would consider his ride a street rod. I personally bought a little battery from DUI for the '66 and it worked OK, when it failed DUI replaced it. So I've got nothing against DUI, but I'm running Crane on one car and MSD on the other.

I second this opinion HEI modules give up over 6k. I personally would not want to carry spare coils and modules around in the trunk. Who would want to have a giant distributor cap staring at them when they open the hood.------------------

Since David Vizard is one of my best friends, I have to make a comment here....
Vizard does no endorse crappy stuff that he gets for free that does not work. You don't see Offy intakes on his stuff do you?
BTW does anyone remember that giant SBC intake test that he did in the '80s for PHR? Many of the intakes were worse than the stock piece. Advertisers were PISSED.
Any writer's reputation is based on actual real world results. If the general public can't replicate those results, then the story must be bogus. You don't see the "Long rod 351" writer around anymore do you?
The DUIs that I have personally seen him use are all in Street/Strip type (under 7000 rpm) motors and he gets good results. Vizard especially likes the timing adjustment knob for Dyno tuning. A 1/2 degree was worth about 8hp on the 392W test.
FWIW the Nascar guys mostly run the dual pickup MSD ignition. A guy came and had Vizard test a $30K (yes $30,000) Plasma ignition that could sense the burn rate of each cylinder and data log etc....
The plasma setup was down like 20 hp from the MSD on an old 18 degree SBC Winston Cup motor (built by the Pettys). [This message has been edited by Mpcoluv (edited 04-10-2004).]

We could never get our trick high buck Holley digital deal to work right either.
Neither could anyone else we know.
I guess that is one of the reasons Holley is out of the ignition business.
One more time!
I feel the DUI has it's place in the market as a simple self contained ignition system.
Just not on a race engine!
I have seen Vizzard endorse some pretty bizzarre stuff over the years (many years)and it still has not made me lose any respect for the man. A lot of it is long gone from the market now too, as are many "trick or the week" products that I have tried personally. ------------------

I remember yrs ago I kept reading in my dragrace mag's how Jacobs had the "best stuff on the market" and how they always would make "X" amount more HP than any MSD system. Ya know, in the 12 yrs I have been racing, I have never seen anything from Jacobs on any racecar. Especially not on any of the fast cars, or cars from guys that are bracket hitters.

In defense of DUI and Jacobs they do make some pretty good Ignition wires. I've never run them but I know some guys that do and they are pretty beefy 10mm wires. I guess it would be VERY hard to get into that market MSD has got it pretty sewn up. I have some Ford Motorsport wires on mine right now, no telling who makes them. I am going to work on getting an MSD distributor back in my car somehow. I may have to pull the intake and grind on it. The unilite has got to go.

FYI Jacobs.
They were aquired by the Mr. Gasket group early this year. Now they have 3 ignition companies. Accel, Mallory, and Jacobs.
I have used some of the Jacobs products on customers cars over the years and have always been pleased with the quality. Especially their E-Coils.------------------

Fastymz: We came out with the Ford DUI because of customer requests and we knew that Ford owners had a lot of wiring to run compared to the GM guys when installing an ignition system. The stock Ford ignition requires wiring between the distributor and the coil and between the distributor and the module box. It has been very successful-in fact, today we make the DUI(HEI) for Dodge, AMC, Landcruisers, etc.

My Dad started the company in the '70's rebuilding distributors. When the HEI came out in '74, he began testing and experimenting with it. The stock HEI had many pitfalls as we discussed here on other posts. My Dad began taking steps to improve the stock HEI(and I joined him in the mid '80s). RHS Engines carried them with their motors for many years(til they closed). We feel we have perfected the HEI, but we don't sit still-if an idea for improvement comes up, we investigate it.
Thanks for asking.

I know you guys have not appreciated my references to articles, but here is one in which our Racing DUI was used in a 800HP motor-don't cuss me-in a Chevy.http://www.hotrod.com/techarticles/50660/ http://www.hotrod.com/techarticles/50660/index3.html

Hot Rod, the masters of mis-information. I stopped reading their bogus 100% sponsor paid for articles when I was 17. Building a big inch high powered motor isnt difficult when manufacturers give you parts, or you have an unlimited budget. And considering my low dollar 357 inch motor was putting down close to 600 hp, 800 out of 540 inches doesnt impress me.But hey, whatever floats yer boat.

Do we have any members in the Memphis area or are going to be, with a high reving race engine? Seems like a test session would be a good thing. Meet them at the track with one of your units, do back to back tests and see if it out performs!

FWIW my cousing, who runs an inline 6 circle track class, was telling me that the 16V DUI race ignition was very highly thought of in his class. These motors turn between 6500 and 7500 rpm. I don't recall if this is the HEI type or not however. I could have been their duraspark...

I was going to stay out of this discussion, but I just can't do it anymore....I personally would never use a DUI, just to get that out of the way. Too big, too ugly, based on the HEI architecture. Never even knew anyone that used one on a Ford. I've had 7 HEI failures in my 2 GM tow vehicles in 10 years. I've tried many different aftermarket components to try for a solution. Best thing I ever did was toss the guts and run an MSD off the reluctor with the remote coil setup. Never had a problem since. I feel it is just a very failure prone system, and would never spend another dime on an HEI component, ever. I feel it's the perfect street rod ignition though, even a moron can hook that one up right. I worked in the aftermarket performance parts industry for several years. In my experiences, I've found there is a huge portion of the magazine industry that will "write articles for parts", promoting anything they get for free. I feel this does a huge dis-service to the newbies, as they treat the magazines like a "Bible". "If it's written in the magazine, it must be true". Unfortunately, most of the time it isn't. Peterson or whateveritisthisweek was famous for this..... Many unscrupulous editors and authors will write in good reviews for parts that they receive for their own projects / vehicles. Bit of a confict of interest. Tennss, I believe that you manufacture a good product. If it was junk, you wouldn't be in business. How exactly is your Duraspark distributor better than others? I would however, like to see an unbiased, non-magazine sponsored, head to head, MSD-vs-DUI-vs-PD's duraspark based setup-vs-whatever comparison hi-rpm dyno test (or actual race car datalogging). Proof IS in the pudding. P.S.: a perfect example of the poor editing and lack of knowledge in general in the magazine industry. This is copied directly from the article that TennSS referenced. 
quote:
Super Street rules require a wet-sump oiling system, so Lunati chose a Stef?s custom aluminum oil pan complete with a built-in-scraper windage tray. Note the cut-outs along the pan rail that allow the oil to drain back into the pan.
...last time I checked, the notches in the pan rail were for ROD BOLT CLEARANCE on a stroker crank, NOT oil drainback. Any question why I have serious doubts about magazine tech?

kid vishus: My point is NOT how much horsepower the article made per cubic inch-the point is that our Racing DUI performed flawlessly in a 800 HP motor.

Hemikiller: Our Duraspark is calibrated on a distributor machine based on the specs of the motor it's going in. We also offer our Dyna-Module and Inferno Coil which mount outside the distributor. This system fires to 10,000 rpms.

If you really need to get the RPM out of a distributor you would run a Hall Effect switch instead of a stator.I think the Hall Effect switch is good for 24,000 RPM

everyone has there opinion about ignition systems (and everything else that gos on a race car!) and more than likely no one is going to change their opinion. but isnt it nice to be able to discuss it and just have fun like we are doing.------------------

capri man: Thanks for the complement. Yes, a forum like this is nice-only in America. The guys have been tough,asked some good questions too. I came to this site after being informed that our DUI was being bashed-called "junk" etc. I'm just taking up for what we do all day everyday for a living.Question, Capriman, is that a DUI under your distributor cover on your website-just teasing!

Tenn, I am a short hop from where you are. How's the wet weather up there in Mempho? Actually, I was there today. Anyway, why don't you guys fill a void and make a distributor that is very small base for a 351c/460 that would clear tunnel rams and be magnetic trigger? You'd corner the market. although the market might be pretty small, I've heard Numerous complaints besides myself on having to run the mallory Unilite. I have an extra mallory here you can practice on! Good luck to your business. ------------------

Kudos to TennSS for trying to post factual information here.
I have just purchased a DUI distributer for my 351w as I was looking for an easy to install street distributer. I'll let you all know how it goes.------------------
