Some didn't think it was.Totally confusing.Most companies only had wires around 900 ohms per foot. Some said it was important for breakdown, etc. I called performance places(locally and internet),hot rod shops, read research on the net, talked to people,etc,etc,etc. He told me if i didn't want to spend that much money,then i should search for a wire that was 8mm, spiral core,with a ohms resistance of 300-350 per foot. A tech from there company advised me to run Autolite platinum cap, with 12 degrees timing. Hello, i too purchased the HEI/DUI from Performance Distribitors( they are the specific builders that MAF gets them from). The reality check is that if there was any significant benefit, all the automobile manufacturers would be required to have them, because incomplete combustion is a significant smog issue. Supercharged and nitromethane engines require a hotter spark to ignite reliably. Racers (and ex racers like myself) use electronic ignitions because they provide a reliable spark at high RPM (>7,500 RPM) where stock coils have problems with incomplete saturation. It also has a distinct down side in the fact that excessive vlotage leads to reliablility problems and failure. Getting the advance curve dialed in makes a noticible improvement, but increasing the voltage is not necessary on a normally aspirated gasoline engine and by itself, I never saw any benefit. This is just my experience from 3 years of racing and dynamometer tuning. OTOH, if your distributor is worn out and is not supplying a reliable spark on time, replacing it with any properly functioning distributor will be an improvement. Fuel combustion is complete with a stock ignition that is properly functioning because the amount of unburned fuel is about 1 part per million and it doesn't change when you change distributors. Hotter spark, stronger spark and longer spark add nothing. As long as it sparks reliably, the fuel burns the same. Please help me clear up where I'm thinking wrong about this stuff. I realize that this is an extreme example (7,000 hp engine) but if there was no benefit they wouldn't do it. I know the NHRA all runs dual MSD Distributors and 2 plugs per cylander. It seems like if what you're saying about stock distributors and sparkplugs were true, racers wouldn't invest in stuff like MSD ignition systems. Also, it seems like a bigger plug gap would allow for a better spark (when you have the power to make it bridge the gap). I know for me I felt a seat of the pants increase when I installed it. has to increase power over the worn out stock dist. So that makes me think that the DUI dist. I've always been under the impression that a better spark provides a more complete combustion of fuel, thus resulting in more power. Pinhead, I've read some of your comments concerning ignition stuff before and I think I don't understand where you're coming from. It's a great upgrade, I really am pleased with it. It takes a few tries to get it right, so be prepared for that. ![]() You'll definitely need to do a lot of timing work to get it all tuned in just right, mine was fine when idling and reving sitting in my back yard, but pinged like crazy under load. end of the wire won't work with your new DUI. The wires have to be HEI specific or the conectors at the dist. ![]() I think I got mine from summit racing, just got a set of Moroso HEI do it yourself wires, much cheaper than MAF's wires and excellent quality. that thing is so friggin over priced, they want like $80 or $90 for those wires. They are available in an assortment of colors.DO NOT get the MAF plug wire kit. The wires have the number of the correct cylinder on both ends, making installation and removal simple. Livewire’s are custom-fit, with no add-on sleeves or assembly required. They also come with easy-to-use swivel boots. ![]() Dirt and moisture is kept out of the wire terminals, thanks to heat shrink tubing placed between the boot and the sleeving. Durable silicone jackets and insulation make Livewire’s long-lasting. It is also resistant to chemical corrosion and moisture. This sleeving is nonflammable and provides protection from a range of -76 to +1400 degrees Fahrenheit. These wires feature space-age, heat-treated glass braid sleeving that insulates them from exhaust heat. Livewire’s can be used with delay boxes and stutter boxes. They have a very low resistance (300–350 ohm/ft), allowing optimum spark travel. Livewire’s have a spiral-wound core that prevents electronic interference. They come with a variety of features that make them superior to ordinary plug wires. Livewire’s high-performance plug wires from Performance Distributors are high-quality wires that can handle the most powerful applications. ![]()
