AndyGJ Posted June 22, 2012 Report Share Posted June 22, 2012 I was looking at a couple of basic upgrades for my SGT as part of my weekend projects, and I was wondering if anyone has used upgraded Coil Packs on their SGT? Here is one from American Muscle that I found made by Accel: http://www.americanmuscle.com/accel-sohc-coilplug-0510.html They also have a set made by Ford Racing: http://www.americanmuscle.com/frpp-coilset-0810gt.html Do these help any or are they a waste of money? Are they any better than what came on our SGTs? (I don't think these were changed at all from stock Mustang GT parts by SAI when our vehicle were upfitted in Las Vegas, but not 100% sure.) Thanks, Andy. Link to comment Share on other sites More sharing options...
jmn444 Posted June 22, 2012 Report Share Posted June 22, 2012 IMO, spark is spark unless you are getting in to super high powered engines. That doesn't stop me from buying the pretty new shiny crap, but I don't think you see any performance increases on "normal" engines at all.

ARMORINE Posted June 22, 2012 Report Share Posted June 22, 2012 bigger coils arnt needed unless your running HELACIOUS amounts of boost. youll see a miniscule increase in horsepower, not enough to justify the cost. Link to comment Share on other sites More sharing options...
SGT0128 Posted June 22, 2012 Report Share Posted June 22, 2012 Agreed....but they are pretty. Link to comment Share on other sites More sharing options...

TheKurgan Posted June 22, 2012 Report Share Posted June 22, 2012 There's one thing on my car that's still stock and it's the COP's. No need to change. Link to comment Share on other sites More sharing options...
AndyGJ Posted June 23, 2012 Author Report Share Posted June 23, 2012 Some of them claim MPG increases....any truth there? I'm sure all of you bought your Shelby (GT or 500) for the gas mileage, too! Just curious if there is any truth in this stuff..... thanks, Andy. Link to comment Share on other sites More sharing options...

andrewnagle1964 Posted June 23, 2012 Report Share Posted June 23, 2012 This has been debated for years on the S197 forum and the answer always comes back a resounding no ! Stay with stock, Like some others have said I spend a tons of cash on stuff and have chosen to stay stock with the COPs Link to comment Share on other sites More sharing options...

Thanks for the advise...that is one item on my short list anyway. I'd rather spend the money for the aluminum driveshaft. I think I'll go for the 93 octane tune ASAP. Any suggestions there? I don't have my own tuner, but there is a local shop (Injected Engineering) that could do the tune for me and dyno if I wanted. Should I just buy a tuner and use a preset tune to save the $$? Thoughts? Suggestions? I'm looking for some additional power for low $$ for now is my main goal. Funds are limited due to 4 tuition bills so I'm looking for bang for the buck!! Thanks, Andy.

vapor08GT500 Posted June 23, 2012 Report Share Posted June 23, 2012 If you are looking for bang for the buck, look elsewhere. The OEM COP are just fine, even under boosted/nitrous apps... Alex Link to comment Share on other sites More sharing options...
ARMORINE Posted June 23, 2012 Report Share Posted June 23, 2012 you can get a canned tune that will run fine. it wont produce maximum power but it will be safe and wont blowup your engine. for maximum output you have to have a dyno tune. remote tuning is good but its just not as good as having a car strapped down to a dyno and making pulls under controlled conditions. that being said if your short on cash i recommend a remote tune as dyno time is money. around tulsa its about 400 dollars to dyno tune a supercharged mustang. that doesn't include the required tuner. i caint remember the amount but remote tunes are less. id look at jpc, lund or bamachips.
