Hey, if they send us a set, we'll install and test for them on the dyno. We can do one on a stock vehicle, and one on a modified vehicle. I'm sure they make a good difference.

I have also run the aftermarket COPs on my car when naturally aspirated. I did not dyno the results, but the car ran smoother, less hesitation and felt better all-around.
I have switched back and forth while running the supercharger from OEM, to MSD to GMS COPs.
I personally feel the GMS COPs perform the best of the three. When I see Brent White I will dyno the aftermarket COPs maybe in May.
When I was N/A though I still was happy with the mod.

I offered this to JR Granatelli last year, offering to pay his price (retail) if they had gains and his cost if they didn't. That way no matter what, GMS wasn't out any $$. I never received a response from JR. It would be interesting to see, since claims are made on the GMS site.

AND NO, I AM NOT BASHING GMS! :nice:

That burning plasma would light pretty much anything.

They were able to actually throttle the engine on gasoline just like a diesel engine: No throttle body, just adjust the amount of fuel injected to determine power output. It could light mixtures leaner than 28:1. And it ran VERY smooth with incredibly complete combustion. I'm not sure what happened to the technology, but if I had to guess, I would say emissions (mainly oxides of nitrogen) probably killed it.

I really want to know the truth about these COPS on a N/A motor. I acually spoke to one of the Big 3 tuners for our Stangs about the MDS COPS today about the before and after results of the COPS. This is what I was told......."they seem to improve gas mileage...they seem to smooth the idle....they seem to improve throttle respone. But we see no improvement in power!!! That is pretty much a quote. This may explain why we have never seen a dyno sheet before and after on this product regardless of the manufacturer!!

I completely agree. I have read posts on other sites of people going from stock/GMS/MDS and back to stock because there was no gain in performance on the dyno.

Why the Cobra coils work great?

Please post that link to those results because I have not seen a single dyno sheet showing no gain. I was one of the people that went back to OEM COPs for a while because the first version of the GMS COPs had several early coil failures. One guy posted he lost horsepwer because he had a bad GMS COP. That does not mean anything. You will lose horsepower even with OEM COPs if one goes bad, duh.

We would love to have some solid dyno results.
