Does anyone with any experience/knowledge on Granatelli Motorsports' coil pack for 3V unit; 28-1812CP. They claim higher spark ignition (hopefully this will clean some of the carbon build up on our spark plugs). From what I read it sounds pretty good, including hp increase of approx 12 ponies. I think with combo with our edge Evo and this will really make our engine come alive. What your thoughts?

 

I don't think it'd matter enough on a naturally aspirated mostly stock truck. Maybe on a supercharged truck or one with head work/cams/etc.

 

How much is it, people post these mods and this is key to whether or not it's worth it.

 

I would not think you'd see much benefit unless you have a high mile truck(with original stuff) or highly modified.

 

When I called Granatelli, the contact person told me around $450 to $550 for 8 pieces. It is kind a $$$. I guess judging from forum response, no one has any experience with these......

 

Way too expensive.. Only reason I could see spending that much moolah would be if you were running some boost.. like 12PSI+.. and you wanted to reduce detonation.

 

The folks over at The Modular Depot have been working with these COPs for a short time now. They have been getting great results, but I can't say that it has been on N/A 5.4s. You could always go over and see what the buzz is...

Apparently this site carries the Granatelli's COP...they want $499.95 for set of 8. Check out the 3V for the Mustang's

 

They have been getting good results with the FI SVT guys, and those with blowers on their 4.6 3v. I doubt you would see much of a gain on an NA 5.4 but its definatly a better ignition upgrade than something like the plasma booster for us. Someone buy em and let us know!

 

You have to spin a Ford COP Modular engine to 6500+ rpm or add 15+lbs of boost to see a benefit from enhanced ignition components IMO.

 

i agree that they are only worth it on a highly modded engine. would probably help alot with spark blowout while running lots of boost.

 

Speaking of, does anyone have a Plasma Booster?

 

Not wanting to get off on the spark plug issue, but,the problem referred to as "carbon build up" looks to me like oxidation. I really doubt if it would help with that.
