Granatelli Coil on Plug Observations - 2003-04 Mach 1 Registry Owners Club

atomicsvt · 08-11-2006, 06:41 PM

Bought them over a month ago from Mustang Tuning for my 01 blown Cobra. Got them fairly quickly but they were the incorrect ones. They had the hold down wing and were for a GT. They (MT) immediately sent me a new correct set and gave me 2 weeks to return the wrong ones. I was happy with their customer service. It appeared the mistake lay with Granatelli putting the wrong stuff in the box they sold, and in fact about 2 weeks later I received the machined aluminum spacers directly from Granatelli to apologize for any inconvenience. Class act.
I did not realize that I had to swap the connector pins for the Granatelli COP's until I actually received the COP's. I thought that was a bit deceptive as the web page stated "direct replacement". I must be a dolt as I could not figure out how to do it without destroying something. I posted on several forums including this one but received no help beyond "it's so easy but hard to explain". Finally went to local Ford dealership and talked with a mechanic who told me how to do it. An hour later everything was installed.
I was able to widen the plugs from .032 to .045 with no blowout at 7000rpm. It is more resonsive throughout the driving range. I am getting about 1 more mpg. I had to remove the Plasma Ignitions or I had blowout. No dyno runs yet.
Is it worth 500 bucks? Depends on your value system. For me it was the only area left that no one had done anything for and with no kids or wife to raid my wallet it was an easy decision.

Interesting.
Did you replace all 8 coils (complete), or just parts of them?
Any pics of the new parts?

I replaced all 8. I have no pics but they look the same EXCEPT the connector is angled upward at a 45 degree angle vice sticking straight out. Originally these were made for 2V engines but if the wing is machined off and the connector pins reversed on the harness they will work on any 4V engine.
I can take pics but how do you post them?

Thanks for posting this. I read the article about the coil packs in the latest issue of 5.0 Magazine. They tested a blown '04 GT (I think) and got around 15 hp out of them. I wonder how good they work with an N/A motor that needs to rev above 7k???
