yes headers do add power between 5 to 10hp, by letting the motor breath easier, anything that restrict's the flow ( like catytlic converter) reduce's horsepower, i picked my headers up for $85 bucks off ebay from a ebay store so u can still find them there, as far as the demon coil goes, u'll find it's double the spark power than standard ( add's up to 5hp)and u can find that for under a $100 bucks also. i bought my diablo tuner on ebay for $150 bucks ( used) are you gonna beat a hopped up gt? hell no and that's not really the point here u will shock a stock gt though when u get the jump on him but sound like a v8 lol
How much can I expect from my v6

Don't even bother with the screamin deamon coil packs as long as your coil pack and wires are good (and I am almost positive they are) you will see very little if any power gains by them. If you want you can upgrade your wires for looks but its not really worth the money.
As far as exhaust goes stay away from Long Tubes, the extra HP that you are going to make from them is outweighed by the sound made from them. If you do decide to spend the money and do headers I would go shorty headers. I wouldn't get some cheap ones off ebay either I would go with a brand that I know has a good quality like BBK or Mac or Pacesetter or Kooks ( I remember one guy saying he had Kooks Shorty Headers on his). Keep you Cats, don't gut them or remove them. Our Stock Cats flow fairly well and the sound that you get from gutting them or removing them isn't at all pleasant.
Like I mentioned before get someone to put the gears in because if it isn't done right they will start to whine and cause damages to themselves over time. I would use either Ford Racing or Motive 4.10 gears and Ford Racings Differential.
I would pay a visit to American Muscle, they have everything you need there and we have a forum discount with them. Good luck with the project!

headers- yes, 5-10hp.
the coil wont do jack. Its worth doing if your coil is dead, but it doesnt add any noticeable different.
as for the diablo, I advise against used tuners. They are often not unlocked, leaving an expensive cost to get it done. Most tuners also use the SCT software and dont support the predator. This is maybe another 5hp, but helps the auto transmission.
Theres perhaps 10-15 horsepower, but Im not seeing the 40-60 that you were talking about.

well this is fun discussion i must say!!i do agree that a coil pack is mininmal (up to 5hp) but with E3 plugs ( on horse power TV) it does add ponies not much granted but if u decide to up grade to a supercharger or turbo later u need the hotter spark anyhow, since the 4.0 is a dog on horse power(210) adding only 5 to 10hp wouldn't let me smoke tires anytime i want from a stop but 250hp will!! lol i would never recomend removing a catylitic convertor but was just stating a fact about restrictive exhaust and they even make high flow cats lol u can pic at any one item and say it don't mean much but put all the pieces together and that where i'm at , if u buy a exporer express supercharger with 8-10 boost u'll get 305hp if u add the intercooler 315hp but is 1500 bucks if u go to the votec like steeda with the whole kit u'll get 410hp but that kit about $7.000 grand ( which includes a demon coil lol. the tune is set for 89 octane on my car and i'm think about a snow's methanol injection for 106 octane which is a small steps to the explorer supercharger i intend to put in lol
That would be RWHP on the Headers. BBK makes a good product and its made in the USA, I would splurge for the ceramic coated headers. I am not sure as to which would sound better but check Youtube. I haven't looked into Shorty Headers since I figured if I was going to swap out headers I might as well go with Long Tubes until I found out about the sound quality lol
If you are looking to free up some ponies you can get an aluminum driveshaft which wouldn't add HP but free up rotational mass and get things moving a lot easier and quicker.
As far as coilpacks are going you are more likely to see gains from UDPs than from the coilpacks and you would need a colder spark plug not a hotter spark plug when running a supercharger. The X-Charger Xtreme is a good Roots style kit and the M90 is good enough to add some decent HP but I do believe that last I checked Explorer Express was developing a adapter kit to be able to add (I forget which) TVS style Supercharger on top the the intercooler.
I believe Shelby sells the kit they have for the Terlingua that they made but I am not positive. Shelby uses the Paxton as their supercharger of choice.
You do know that Hellion is a turbo right? lol

We've done a lot of 05-10 V6s and I can tell you what DOESN'T work based on dyno testing and what DOES work also based on actual dyno testing.
The Coil backs don't add horespower AT ALL on a natually aspirated 4.0. On most supercharged V6s they dont't add any power either, but above about 12 lbs of boost they let you go back to a wider (closer to factory) gap which helps the idle quality and fuel mileage slightly.
The two different throttle spacers we tested both LOST 2 horsepower.
Dual exhaust and better mufflers really helps. The Semi-dual (2-into-1-out to 2 mufflers) magnaflow kit works really well naturally aspirated. Supercharged a true dual works best.
The Pacesetter dual exhaust kits are cheap but fit like crap.
The most powerfull '05-10 V6 we ever had in our shop with any power adder of any kind was Vortech supercharged with a Snow water/meth kit.
The best driveability (smoothness and consistancy of response) out of the bunch (Procharger, Vortech, X-Charger, Turbo kits) is from a well tuned Vortech.
A larger throttle rarely makes any more power than the stock one whether naturally aspirated or supercharged (with the exception of an Xcharger), but the throttle response makes the car FEEL much faster.
I could go on...

now we're getting to the meat of the matter for blue slug!!! lolas we all are saying there are many ways to stroke the beast out of what he has now and the key is to take the small steps that he can afford now , do research on the parts he wants and ask more questions lol and by the way it's mp90 not m90 thats for the 3.0 and 3.8 i wish the 07 could use the M90 i could have bought one on racejunk for 300 bucks used!!! and for the last thing my granny called me a LIL"HELLION back in 1968 i think i beat the hellion turbo by a few years lol
So whats everyone's take on BBK, as in quaility of parts? I always am doing research into what I want to do with my car I know Exhaust and Drive train are my 2 big ones, with exhaust I must of went over quite a few forums and came out with a general sense BBK doesn't have good QC with many posts about leaky headers and faulty throttle bodies. What found interesting was alot of recommendation on ebay headers for around $100. This was around 2 years ago and I did my ebay search found plenty of $100 headers for sale, now currently only 1 seller names RaceDesignImports sells a set which resemble polished Pacesetters. Kinda wondering if anyone has come across this also, I'm pretty sure Gibson and MAGS make far better headers but at the price if they perform close to advertised for a daily drive wanting to keep NA think thats a great deal.
BBK has had a lot of troubles with their throttle bodies I know that much as far as their headers go I am not sure about them. For some reason Pacesetter stands out as something to avoid but I can not think of a reason why so it just might be something concocted in my head since I would recommend look up what Mac has. I know a few people that run BBK headers and don't really have issues. Mac does make some good exhaust parts so check what they have on 4.0 headers. I have never even heard of RaceDesignImports to be honest and I would stay away until I found out some reaserch on them and their use on Mustangs. Also take into mind on ebay that $100 headers on ebay may not be of the best quality and for me if I have to spend a few extra bucks to get a quality piece than I am willing to do that. Also when replacing your headers I would recommend using new OEM gaskets as some times the aftermarket gaskets will leak especially with cheap headers.
My exhaust plans always end up in smoke lol, now you mention the MAC headers and went back to refresh my memory alot less then I was expecting for them on AM.com. As for Pacesetter alot of negative coems from their Black painted parts, the paint is extremely poor and very quickly when exposed to the heat and elements headers are the paint begins to crack and peel, but I think Pacesetter acknowledge this saying the paint is "shipping material" and only meant to protect headers during transport and to expect a flaking header lol. pretty much for heards I want more power better sound but don't want to spend alot, and it shouldn't leak or rust. or am I asking for too much lol.
Mac makes pretty good exhaust part, the factory headers flow well enough but adding shorties will add a few HP and will mellow out the sound a bit. It's not going to make it quieter but will reduce raspyness a bit. Ceramic coated headers will be a improvement over stock and will not get as heat soaked or transfer heat as much as the stainless steel headers. Most people recommend getting ceramic headers over just polished ones for those reasons. OEM header gaskets will ensure it doesn't leak as long as all the bolts are properly assembled .
BBK headers work good and offer good performance-per-dollar. They aren't top-of-the-line stainless steel with beautiful tig welds like some of the headers out there, but they get the job done, and done well, at an affordable price.
There is a big difference between being "affordable" and being "cheap." You don't want cheap. Cheap is junk. BBK is affordable.
