I saw an ad for plug wires from Granatelli Motor Sports. They claim their "coil near plug wires" Increase hp by 12-15 hp due to o ohms of resistance. Has anyone tried these?

 

I can say that after being in the Corvette business for 8 years I have not and probably will not see any power increase from spark plug wires.

That's exactly what I said to them when I called to have them explain their hp claim. I thought Granatelli motor sports was one of the good guys. Not trying to disclaim anyone...just the facts please!!!

 

they forgot to tell you that is only when you install them with the tornado.

 

Yea GM left 15 HP on the table for crappy wires.

What is the other thing they sell that never worked but people keep buying here?

 

and some STP Motor Oil Treatment.

 

funny

Hey guys its Mike from Granatelli Motor Sports here to elaborate on how our coil near plug wires work. I understand that there will be some confusion of how our wires work. A relatively new product is naturally going to have some misconceptions. Our performance ignition products are an industry first, and as stated by a previous post, have "0" OHM resistance.

Stock plug wires on GM vehicles have around 600-900 OHM resistance. Our recent test showed about 800 OHM resistance as accurate for new stock GM wires and confirmed 0 OHM resistance with our wires (see GMS wires test on a new C6 Z06 video). After installing our GMS coil-near plug wires, we made 10 RWHP and 17 lb-ft torque on a Corvette Z06 nearly straight out of the dealership. Depending on the condition of your ignition system is how much OHM resistance the wires have. I recently pulled wires off of a '01 Camaro SS and noticed a heavy amount of corrosion throughout the wires. For a car that is 5 years in age with a significant amount of corrosion on the stock wires should raise concern to anybody that has performance in interest.

That being said about stock wires, lets look at our lead competitor's wires. One company claims their wires have 40-50 Ohms of resistance per foot. They also claim that they have the "lowest resistance of any helically wound wire". Did they forget about us? Helically simply means "pertaining to or having the form of a spiral", so that includes our wound stainless steel core. Lets say we took 8 feet of our spark plug wire against 8 feet of their spark plug wire, which is close to the length of a set of Corvette wires. Their wires would read 320-400 Ohms of resistance and ours would read 0.4-0.8 Ohms resistance. Big difference.

Now lets take a look at quality and design. Their wires contain a "ferro-magnetic impregnated center core"...in lame-men terms, a circular polarized core. One long dissection and I still don't know what it's made out of. Then, on the outer shell, they also used Kevlar for strength. Kevlar is not a defined material and is simply considered as heat-resistant fibers. Then they used copper for their conductor. Ours is a solid, stainless steel core. In all obviousness stainless steel is less likely to rust and is a much better conductor.

Back-to-back comparisons shows we are not playing the "smoke and mirrors" game unlike the rest. Our product is the best quality and conductor hands down.

A video of a new C6 Z06 testing out our wires on back-to-back runs from stock to GMS wires. 10 RWHP & 17 lb-ft torque increase

 

like the mass air flow sensor? 8-25 HP

 

Our ignition wires do work. If the Corvette video isn't enough for you, check out the Viper or Ford GT also running the wires on our media portion of our website.

To give you a breakdown, the Granatelli wires our made with a braided, solid stainless steel core. Most of the other companys in the industry that make high performance ignition wires make them out of copper. They are 8 MM in diameter.

The design of our wires allow for the 0.05-0.10 OHM resistance. Stock is around 600-900 OHM resistance, and other aftermarket wires are around 40-50 OHM resistance.

 

um for the price of your wires, I can afford to lose a little HP and torque.
Just because we have corvettes, doesn't mean we want to throw our money away.
Because of your prices
I went with another competitor of yours, and got a seat of the pants noticeable performance increase.
So, yea better wires do work. But:
When you compared the resistance from your wires to your competitor's wires, you said that you would have approx. .8 ohms, and the competitor would have around 320 ohms, that was collectively, maybe for Gen 1, and that doesn't apply here.
In truth, yea your wires may work, but the competitor's wires at 50 ohms per foot would yield approximately 25 ohms since on a corvette
LS1 engine architecture, the wires are approximately 6-7 inches long.
Since the stock wires would have approx anywhere from 1700 to 2500 ohms per foot (depending on where they get the cheapest wire this month), yea utilizing your wires, the spark energy would not be compromised, and all of the power of the coils would make it to the plugs.
But at 25 ohms per wire, it's achieving the same thing , almost.
When I changed wires, I also went with better plugs, too.
I would like to see you adjust your prices according to the amount of material used in your product, with an adjusted rate of R&D consumed in that product application. Not just arbitrarily trying to recoup all of your R&D money in every set you sell.

I would bet that it was a small block Chevy that you originally put on the engine dyno, and did the research on because of the low cost to obtain a chevy engine, dyno shops are set up fopr a chevy already, and every other application was obtained from the engineering data supplied by all of the manufacturers for aftermarket suppliers, even though you may have paid the manufacturers for such information.
ok, back to reality, maybe making the wire in limited applications might be a little costlier, but it goes without saying the earlier corvettes were manufactured in smaller numbers, but the wires were approximately the same as the other 40 thousand cars and trucks manufactured by Chevrolet at manufacturing time and is ever increasing.
Since 70% of the hot rod culture is using the small block chevy, approximately 8 million to date,and now some are going to the LS architecture engines, and thousands of them are being utilized in hotrods and show cars.
With approximately 3 million cars and trucks and SUV's utilizing this engine, your price as advertised should be less.
The reason? most engines are swapped from the original car to whatever the new car it will be installed in, and the engines will continue to be utilized, rebuilt, and reutilized some more.
It's not like most of them will be scrapped or sidelined.
Still, you have to share the market with your competitors, and while you still have a superior product, your price as distributed is too high.
In order to grab a larger share of the market, and to make us LS engine guys happy, lower prices are necessary.
All you have to say is (advertising spiel)
Of the 125,000 corvettes manufatured in the last 5 years, we spark (your market share here) corvettes based upon the number of wire sets sold.
The rest of the Chevrolet world is going to follow the corvette lead and say "well if the corvette guys are using them, we should too".
Believe me, all of the "Chevrolet World" view the Corvette as the top runner.
Um if you didn't believe it, you would not be in the Corvette forum pages either (Please dispute )

The OEM wires are high resistance INTENTIONALLY.

Low resistance wires tend to leak RF radiation, affecting the radio reception, and in extreme cases, possibly computers near the wires such as the EBCM and PCM.

If your OEM wires are delivering sufficient spark to light the fuel/air mix, a hotter, fatter spark ain't gonna make a wit of difference. Possibly if you're running a turbo or supercharger, a significantly richer mix than the OEM PCM program was set for, or NOX, (all of these require a "stronger" spark) then lower resistance wires MIGHT make a difference.

Picture it this way, take the Hindenburg and apply a match to it. Then try same thing with a blow torch .... net result either way ... KABOOM.

 

You missed a critical difference there. With the blow torch you can stand back from the KABOOM that crucial extra 1 or 2 feet and therefore charge more for the blow torch. Marketing 101 my man!

 

Last time I changed my plugs I went with GM High Performance wires. Beans had em for about $60. Probably no real increase but the OEM's were 7 years old.

 

Stainless steel is no where near as good a conductor as copper. In fact, silver is the only thing commonly considered to be a better conductor than copper.

Also, solid wire is not as good a conductor as stranded. Electricity travels on the surface of wire, not in the core. There is much more surface area on stranded wires vs one solid wire.

I have never seen copper rust. You have to have iron to get rust (iron oxide).

 

 

another way to expensive over rated product..

Good, wires dont need to cost more than 60-70 bucks...

 

Andy Granatelli is so full of **** his pants must have a brown stain on them. I had a lot of respect for him when he actually built and raced cars, but after he started that company he has sold nothing but the automotive equivalent of patent medicine and snake oil.

The only time 0 ohms is achieved is by cooling certain materials close to absolute zero. This is called superconductivity. If they have some 0 ohm conductors, they could revolutionize the world and make billions by starting with power transmission lines and electric motors. Stainless steel a better conductor than copper??? Look in any materials book. The only materials that conduct better than copper at non-supercooled temperatures are gold, silver, and platinum.

As someone said in another post, the resistance of the stock wires is intentionally high to suppress RF radiation. This is so you will not hear a bunch of static on your radio.

This reminds me of that ridiculous STP commercial that they ran on TV 30 years ago where they dipped a screwdriver blade in STP and Andy himself showed that he could not hold on to the blade with the STP goo all over it. As if that proves anything.
