Granatelli Wires vs Stock Wires Granatelli Motor Sports shows you that their spark plug wires will give you more horsepower and torque. On this 2010 Chevy Camaro, you will see the difference between the stock wires versus Granatelli wires. Watch the increase right before your eyes as the test is done on a dyno. Granatelli ignitions wires have 0.00 OEM.

I am wondering if the gains were because of its boosted. Not the numbers, but the big increase .... because its boosted.
I just heard while watching this, he is going to do a STOCK car next. I would imagine single digit increases. JMO

Very cool, I may have to pick up a set.
That said id be curious on your opinion of the following: I believe oe wires are wound into the shape of a coil. The added length of using a coiled structure results in a higher series resistance, but it also adds inductance to the circuit. If your wires are straight, or coiled less tightly they would have a reduced resistance and inductance.
In an inductive circuit, the flow of current lags the applied voltage. The higher the inductance, the more the lag. Assuming the difference in the wires includes a reduction in inductance it would effectively retard the timing. The coils are obviously triggered with the same timing by the computer but due to the reduced inductance the spark current flows sooner in the Granatelli wires which this car might like.
So just a hypothesis, curious what you think about it. As an electrical engineer it doesnt seem likely to me that removing 0.8 ohms from a circuit with at least many hundred volts at what must be pretty low current would result in such a significant gain.
BTW, when I get a set ill throw them on my LCR meter and let you know what the inductance is relative to my current set of accel wires.

That is what I was thinking 0.8 ohms is pretty insignificant considering the voltage. I have seen spark plug wires in the 100's if not 1000 ohms. Could be some other properties about the wires.

I also thought the video wasn't to professional. Very cheesy/wiseguy like.

To be clear im not baggin on the wires or Granatelli at all. I dont doubt the increase in performance and thats impressive for some wires. . .and yeah im an EE but I am wrong multiple times every day. I just want to know for sure what to attribute the increase to. I do plan to buy a set, what the hell, right?

I bought some of their spark plug wires maybe 8 years ago for my 89GTA. I will say they are a quality set and have performed very well. As to the power gain I can't say as I never did a back to back dyno test. If I have to buy some spark plug wires I might give them a try for my L92 motor.

In this video, we use MSD's own tester to compare our Granatelli Wires to other popular / most commonly used competitors and show WHY Granatelli remains the king in the industry. Granatelli ignition wires test vs. Magnacore, Mallory, MSD super conductor 8.8., Moroso blue max, Accel 300+, and Taylor.
