Gen 2 V8 Owners !! Performance Ignition coils !!! Testing them now

[Todd Z]

Checking the possibility for a group buy on Sultans of Spark from Performance distributors, Ignition coils for the 4.6 v8 !!!



I got a correct set for the Adren and I am running them now......



The truck idles smoother and takes off a lot better then stock.



From PD

The SOS Coils are designed with increased windings to boost spark output up to

40,000 volts! That is a 60% increase in spark energy over the 25,000 volts produced by the stock coils.

They are black body with the 1 sticker on them..... They body's are made by the same company ans the Granatilli ones, there is really only 1 manufacturer of the boots and body's.





I will do a group buy if there is interest once I am happy with the testing.....



PD sells them at $299 + ship for the set of 8, I will do a group buy cheaper !!!



Thoughts??



Thank you



Todd Z

You have my attention!

 

[Nick Fisher]

Very interested

What is the coil part number? 31750?



I'm going to ask a noob question since I've never messed with spark plugs or coils before...



Do I need new spark plugs with these coils? Should I get new ones anyway?



Will this require new tuning with the SCT Xcal3?

IMO if you can't alter the control side of the ignition then what is the use of using a coil that has the potential to put out more voltage. A coils output varies by what the spark plug and cylinder dictates not the other way around and without altering the control side of the coil I don't see much room for improvement. Now if you had a modified vehicle, something where cylinder pressures were higher, than I think a coil capable of higher output is essential.



All this has got me thinking as to the actual output of one of the stock coils, 25,000 volts seems a little low to me. Next time I have the chance I put a scope on one really quick and check it out.



JMHO

L1,



As with the 4.0 V6 coil this is not sold as a HP making item..... IT is more for those running Lower air to fuel ratios so you get better burning of the mix.... On the v6 the OEM coil breaks up at the higher RPMS, ( we scoped my OEM coil) and the performance one did not, The truck had smoother accel and idle....



Well worth it IMHO......



Rachel drives the 2010 and i installed the coils with out her knowing....



She drive it to and from work and when she got home I got " hun, did you do any thing to the truck, I said No why?.... She said it runs like it broke in and smoother then it ever did....I said it must be the gas...... LOL... I do this stuff all the time to get a "True Test" on the mods I do..



Will see.... They claim more MPG too But thats why i test and ask....

l1tech - so based on what you're saying, you would consider a supercharged Gen2 V8 to be a good candidate for a higher output coil then?



Todd - would you know what the warranty would be on this coil?



To Psycareyo's question...

From my mustang days, it would seem to make sense to get higher rated plug wires if one was to consider a higher output coil, right? Different (hotter) plug too? l1tech or Todd Z - your thoughts?



Thanks guys, and Todd for the R&D testing. :banana:

 

[David Roll]

New wires, plugs and coil. Bringing back memories of the 70's for me. The website said .84 second 0-60 decrease - worth it? I don't know.



Keep letting us know about your "trial" Todd

 

[Todd Z]

On the gen2 v8 you have 8 small coils and no wires.....



The warranty would be what ever PD currently has as their warrenty...



I can find out..



Todd Z

 

[TrainTrac]

I hope it's a good one. I had to PD Screamin' Demon coils crap out on me,:banghead: and went back to an OEM coil.

 

[Todd Z]

I have talked to PD about that, Their sales Vs. returns doesn't alarm them and I personally have sent a couple back.....



As for these I am being told these are not manufactured but bought by them manufactured to their specs, so I am sure there will not be issues....



Like i always do, I run everything I sell......

A stronger ignition system is a must on a supercharged vehicle as there is higher cylinder pressures due to supercharging. Anytime cylinder pressures increase for any reason it takes more voltage to fire the spark plug. Now under normal driving you wouldn't probably feel a difference but once you got up in the upper rpm range adn on the throttle hard you would definetely notice a difference.



As for plug wires..GEN 2 v8 doesn't have any...but anyway yes a heavier plug wire would be recommended. The stock plug wires just don't have what it takes to properly get the voltage to the plug, either the core will burn out in time or you will have a voltage leak through the insulation. As for plugs generally speaking when supercharging ot turbocharging it is recommended to go one heat range colder to start with, you never want to go to a hotter plug in this situation as detonation becomes an issue.

Must be nice to have a wife that notices a change in vehicle performance...I should be so lucky. Did you by chance reset the pcm after installing the coils?

 

[chargedtrac]

Thanks l1tech!



I'm providing the following only as informational, not as an argument for or against this topic\tread, as it is from a Sponsor.



I posed some questions to Torrie at Unleashed Tuning re: the hi-po coil, wires, plugs and any need for a revised SCT tune if one was to go that route.



He replied that he "had never seen an ignition component do anything in regards to HP and TQ over factory components on any of the current COPD Ford ignition systems." He said he did tons of testing with his GT and other s at real hi HP levels to see if they could come up with something superior to stock and could not. He mentioned that most fail to understand how much money and resources the OEMs have to build parts correctly in the first place.



I appreciate his and all the discussion and input on this thread. I'm going to digest this some. I'll be curious to see how Todd's experience is over time, assuming Rachel allows him some driving time. :driving:

 

[scott degroot]

I would have to mainly agree with Torrie but only when it comes to a vehicle in stock form. Once major modifications are made, such as supercharging a stock motor, then there may be stock components that just aren't up to the task.

 

[Robert Caffyn]

Jegs has Granneteli 45,000 volt "hot street coils" for $249.99 for 8. Just an FYI. Bob

 

[chargedtrac]

l1tech - I would agree with you. I guess I don't recall reading about guys beefing up their ignition systems on the modular V8's (Stangs) like other more common mods. The whole premise does make sense.



Off of Bob's find, doing some searching on Granatelli Motorsports website I'm reading claims of "increases mpg up to 10- 15%, increased hp and torque, easier starts, zero ohms of resistance."



The Pro Series 60,000 volt coils provide 40,000 more volts than factory coils, ideal for supercharged, turbo and nitrous applications where spark blowout from weak factory coils is common.



Even more tempting if Todd thinks there might be a group deal down the road!

 

[Carey Frennier]

One thing that has me really interested is not the measured hp or tq gains. The gen2. V8 has decent throttle response at best. It's off the line acceleration is weak. If simply changing the ignition coils out for $300 significantly helps this, it's worth it. Todd is testing it. He says it's a marked improvement. I'm going to wait to hear more buy my interest is peaked.

L1,

I have no problem saying I have the best wife in the world !! 17 Years strong, Loves cars, Love car shows, Loves drives, Speed all the guy stiff !!!



Heck I spackled the garage yesterday afternoon and went to Lowes that night.... I came home to the walls sanded and wiped down and Test spots of primer on the walls....



She is a Catch and a half and I am dam proud of her !!!!





As for the PCM, With the coils I did not, I normally do with intake, or exhaust items that make a large difference, I did with My TB but not the coils...



I got to drive it at some point this weekend..... LOL
