Justin: Hey, Justin with Americanmuscle.com here with a stage three, power pack bolt-on build up for an all '07, '09 GT500's. The focus of the stage three power pack is to take our already worked up GT500 to the next level and beyond. How are we going to get there? Well, for one, we're going to make sure our cars ready to flow some serious air, improving on both the intake and exhaust side of the equation. On top of that, we're going to add a little bit more boost to our car and see what kind of numbers are possible with the factory Eaton m122 blower still in place. For starters, lets set the table for a little bit more boost. Once you start getting around 550 wheel horsepower in these cars, that factory throttle body really becomes a big restriction. And since we're pretty much already there now with our basic bolt-ons and 2.6" pulley, that factory throttle bottle just had to go. In its place now, is the Ford Racing twin 65 millimeter cobra jet throttle body. This is the same throttle body used on the purpose built, Cobra Jet drag car so you know its proven. This is going to replace the twin 60 millimeter stoker with twin 65 millimeter openings, allowing much more air into the super charger and into the engine. Since it is a Ford Racing part, you know the quality, the fitment, and the electronics are all going to be dead on. And lastly, I know we're all about performance here in these power packs, but you can't deny, this is a very good looking part. Polished billet construction and the Ford Racing logo looks so good under the hood, especially along side that JLT carbon fiber intake. Now that we open up things on the intake here, lets take a closer look at the exhaust. One of the biggest disruptor in exhaust flow on any car is the factory cats. They're just performance killers, and that was certainly the case here with our Shelby's. So to fix that, we installed this off road x pipe here, full stainless steel construction throughout, mandrel bends, and 2 3/4 inch tubing. Best of all, really going to uncork the flow of exhaust and should transform our exhaust note into something much more sinister. Speaking of that exhaust note, if getting rid of the factory cats weren't enough, add flow masters outlaw series axle back here has definitely given this thing, a tone worth of one of the baddest Mustang's of all time. In fact, listen for yourself. We chose the outlaw series again because of its straight through design which is going to increase the flow of exhaust, when working with that off road x pipe we just mentioned. Now this is basically just to ensure that our GT500 is ready to move some serious air, which is very important here in the stage 3 power pack because we are going to be throwing a few extra pounds of boost at our car. So with that said, lets get out from underneath the car, head back up to the engine bay, and I'll show you guys where that extra boost is going to be coming from. Since we already have the 2.6" upper pulley here in our GT500, the options for adding more boost are a little limited. In fact, the easiest and really only way to do so, is by adding a larger, lower balancer. So we installed a ten percent lower balancer from Innovater's West here on our '08 GT500. The 2.6" pulley with that balancer is actually a very popular choice with any GT500 owners looking to get the most out of those Eaton blowers. The Innovater's balancer is much lighter than our factory '08 balancer, which will be dropping a rotational mass and by increasing the diameter by ten percent we should be looking at three to four pounds more boost, which will put our Shelby at about fifteen or so pounds of boost when its all said and done. This is pretty much the safe, tried and true limit of efficiency of these factory and 122 blowers, that is of course, without any additional cording or pulling, like meth injection. You start spinning them any faster and heat really becomes an issue, and at that point the super charger begins to loose its efficiency, which means a drop in power. To help keep things cool here in our Shelby, we installed the Afco Pro Series heat exchanger which does include dual ten inch electric fans, to help keep things even cooler. The Afco itself is a very nice piece. Its built extremely well, its great, and it does include everything you need for a painless instal. Because of this, its an extremely popular choice with terminator owners and their GT500 owners out there. In fact if you want to read up on some of the reviews, or learn more about the heating danger itself, just go ahead and click on the link below to visit the product page. So now that we have all of our stage three mods in place, we're gonna move the car over to the Dino and let Mike in the band of performance team step in and let them do their thing, but before we do, I just want to remind you guys to subscribe for our YouTube channel if you haven't done so already, just to check out some of our other bolt-on build ups and more mustang content. All you have to do is simply click on that link below.When the stage two power pack was all finished up, the car was making 548 horsepower, and 545 pound feet of torque. A the end of the stage three power pack, the car is now making 581 horsepower and 600 pound feet of torque. Giving us a peak gain of 33 horsepower over our stage two numbers, and gains of 47 horsepower, and 59 pound feet of torque throughout the curve. So to recap, with all three power packs installed, we went from a base line number of 434 horsepower and 432 pound feet of torque at the rear wheels. 581 horsepower and 600 pound feet of torque. That gives us a peak overall gain of 147 horsepower and gains of 157 horsepower and 169 pound feet of torque throughout the curve. That's going to do it for the stage three power pack bolt-on build up for the 2007 to 2009 GT500. Our 2008 GT500 started out as a pretty formidable street car, but over the course of three different power packs which included a bit more boost, bolt-ons, and a quality tune, it has turned into an absolute monster that is ready for just about any challenger that might want to test it. At the track, or at the next red light, we hope you guys have enjoyed watching these power packs, don't forget to check out stage one and two, and for all things Mustang, keep it right here at Americanmuscle.com.

Nice throttle response
Noticeably quicker acceleration in the lower gears which is nice, and adds a little deeper throaty sound as well. Expensive but worth the performance gain and it looks good underneath the hood as well with the shiny chrome.Helpful (0)

Looks great but Still needsa tune
Installed in under an hour both the throttle body and the JLT super big air intake. I installed the tune with the SCT X4 for the air intake but the car is still running lean and throwing codes. The throttle response seems to be improved however I lost about 5 lb of boost. My custom tuning shop acceleration Automotive here in Edmonton Alberta is going to be putting it on the dyno and creating a custom tune on the 15th. I'm really hoping that that takes care of my issues and this throttle body and air intake or an improvement.Helpful (2)

where to begin
I had realspeed automotive, Bohemia, NY install this with the JLT carbon CAI, along with sct 4 dyno tune performed by Dan Carlson. Shelby already had installed ARH LT Headers with hi-flow cat and xpipe. Mustang dynoed 630 RWHP.Helpful (7)

Which is better throttle body for 2007 gt 500 Ford super cobra jet oval or Ford twin 65 cobra jet
We would recommend the Ford Performance Twin 65mm Cobra Jet Throttle Body for most cars, unless it is heavily modified. Turbocharged/Supercharged cars would do better with the Oval throttle body rather than the twin 65mm.
hi there,i have a 2014 5.0 and was wondering if you have to repin this like you have to do with the single blade cobra jet throttle body.looking to get this with the cobra jet intake..thx ... kena
The Ford Performance Twin 65mm Cobra Jet Throttle Body will require being repinned when you are installing it with the Cobra Jet Intake Manifold.
Would this fit The Cobra jet manifold and intake and would it fit on my 2014 5.0
The Ford Performance Twin 65mm Cobra Jet Throttle Body (07-14 GT500) will fit the Ford Performance Cobra Jet Intake Manifold (11-14 5.0L) item #50430 (www.americanmuscle.com/cobrajet-intake-manifold-1113gt.html). On the Ford Performance Cobra Jet Intake Manifold item page, if you look under the "Buy Together" tab, you will see the drop down option for the Ford Performance Twin 65mm Cobra Jet Throttle Body. Since they both have the oval throttle body opening, these will be a good fit.
I bought the cj manifold for my 15 gt. I imagine this tb will be compatible but will I be required to repin or will it be an easy bolt on plug and play?
This would not be a direct plug-and-play for the Cobra Jet manifold on 2015+ models, other modifications would be required.
It's telling me this won't fit my 2013 Mustang GT, however, I am buying the CJ manifold. Could someone explain will this confusion? Am I being told it won't fit a "stock" GT or won't fit at all?
This will fit the 13 GT once the Cobra Jet intake manifold is installed.
The Ford Performance Twin 65mm Cobra Jet Throttle Body will not fit the 2007 GT Mustang equipped with a Ford Performance Intake Manifold.
You would need to repin it to make it work, we suggest having a shop do this.
We have not tested the Ford Performance Twin 65mm Cobra Jet Throttle Body with the Roush Supercharger, but we believe this will work.
Unfortunately, this part isn't50 state legal and is not CARB approved. This part would only be for off-road use.
The Ford Performance Twin 65mm Cobra Jet Throttle Body is compatible with both the 2.9L and 3.4L Whipple superchargers, although flow may be on the low side for a 3.4L
We have not tested the Ford Performance Twin 65mm Cobra Jet Throttle Body with the Roush TVS superchargers, however we do not believe this would work with the elbow included in these supercharger kits.
The Ford Performance Twin 65mm Cobra Jet Throttle Body is not specifically designed to work with the Roush Supercharger. It is designed to work with the stock supercharger.
This Ford Racing Twin 65mm Cobra Jet Throttle Body is specifically designed as a direct bolt on for your 2008 GT500 and will require a tune to work efficiently so no air/fuel problems arise.
This Ford Performance Twin 65mm Cobra Jet Throttle Body will work well with the Ford Performance Cobra Jet Intake Manifold, Item 50430. https://www.americanmuscle.com/cobrajet-intake-manifold-1113gt.html
Hello! This throttle body is not compatible with the new S550 Mustangs.
