      Review & Installation Video

      The Roush Phase 1 TVS kit will be for the manual and automatic 2015 through 2017 GT owners out there who are tired of going slow and wanna step into an all-inclusive turnkey supercharger system from one of the most trusted names in the Mustang aftermarket. Now, the Phase 1 kit will be the company's entry-level TVS system and will result in 670 horsepower and 545 pound-feet of torque to the crank while using the included Roush calibration in 93 octane. However, interested buyers can also use a custom tune of their choosing if preferred. Now, the price point for the Phase 1 kit will hover right around $7,000 and the install will get a full three out of three wrenches on the difficulty meter, with a little bit more detail to come later in the video. Now, before we go over what is included here with the Phase 1 kit, let's briefly talk about what kind of power you can expect to the tires when using the Roush Phase 1 system on your S550 GT. As pointed out earlier, guys, Roush does give you advertised crank numbers when using their included calibration. Now that is important to mention because numbers might change slightly if you decide to go with an aftermarket tune or custom tune instead. Now, since this video is more of a general overview of the system, we don't have any in-house chassis dyno numbers for you. However, it has been my experience that drivetrain loss typically soaks up about 100 horsepower and roughly 80 foot-pounds of torque depending on your transmission. So, with that said, I would expect to see anywhere from just south of 600 horsepower to the tires and maybe just south of 500 pound-feet of torque to the tires again when using that included calibration in the Phase 1 system. But with that out of the way, let's break down some of the kit a little bit further. And obviously, we don't have much on the table with me in this video, guys, instead we just have the centerpiece if you will, and that is the Eaton TVS 2300 our fact which is housed inside this guy right here. Now, the TVS or twin vortices series is an extremely popular design that utilizes a twin four rotor lobe pack, and those rotors are twisted 160 total degrees, which is basically just gonna create a more efficient flow over older positive-displacement style blowers and is able to make much more power but at lower boost levels. Now, some of the benefits of going with a TVS style supercharger over other forms of forced inductions such as turbochargers or even centrifugal blowers will be the instantaneous power and throttle response along with a very flat torque curve that is a signature trait here of a TVS. Now, there's nothing to spool up. There's nothing really to weight on here with a smaller positive-displacement blower like this. So all together again that power delivery is very linear. It's gonna make this a great option for just about every driving style out there, whether you're drag racing, road racing, or you're just using this on a street car, the TVS does it all and does it all very well. Now, with the Phase 1 kit, you are gonna find the lower unit which is the other piece I do have on the table here, and this is actually your air to water intercooler portion of the blower system itself, which will be used with your included heat exchanger here, otherwise known as an LTR or load temp radiator. Now, just a heads up, this kit does not include any electrical fans, and that is something that you can possibly add down the road if you are interested. Roush does also include a twin 60 millimeter throttle body with this particular kit and that is fed by their low restriction air induction system and corresponding sealed airbox. It should be noted that both the throttle body and the airbox or intake are upgradeable down the road. So if you ever wanted to upgrade, go for a little bit more power, you could do so. However, as it stands, the kit and it's included components will have no trouble making the advertised power claims. The Phase 1 kit will also include the 85 millimeter pulley which will put the car at a very conservative eight to nine pounds of boost depending on your existing modifications. I say that because mods like a set of long tube headers, for instance, will lower boost slightly thanks to the reduction in back pressure, so just something to be aware of there. Now, the pulley much like other components in the kit such as the throttle body and intake can easily be upgraded down the road if you ever wanted to add a little bit more boost and subsequently a little bit more power. But just know if you do start upgrading stuff, a new calibration will be required in addition to make some changes to your fueling. Speaking of fueling, Roush does also toss in their high flow fuel rails in addition to a set of 56 pound injectors to help fuel the newly blown Coyote setup at this hour level. Again, injectors, another possible area for upgrade down the road if and when the urge strikes for a little bit more power or maybe you wanna start playing with some E85. Finally, Roush does throw in all of the required fasteners, all your wiring, brackets, hoses and everything to get this system installed on your S550 GT. Now, before we do get into the installation, I do wanna point out that the included calibration of the Phase 1 kit does come in the form of a tuning voucher and not a handheld device. Now, this voucher will allow you to obtain your calibration from Roush which at that point can be loaded to your car via a few different devices, such as a J2534 interface tool typically found at your Ford dealership or even a dongle which can be sourced from maybe the aftermarket or one of your buddies. If neither one of these are available to you, you can always remove the PCM from your Mustang, send it off to Roush. They'll flash it for you and then send it back, but that will cost you an additional fee. But switching gears, let's briefly graze over the install. And again, this is a topical overview of the kit here, guys, and as such, we're gonna keep it short and sweet on the install. Full three out of three wrenches on the difficulty meter, a lot of steps as you might imagine. So if you're not terribly comfortable in the garage with something like this, I wouldn't hesitate to reach out to your local shop. A lot of install, some clearancing of the front timing cover in addition to a little wiring. So definitely for the more experienced mechanics out there. Give yourself at least a day in the garage. More than likely though, a full weekend to get everything knocked out. Make sure you have a nice set of tools on hand before getting started and be sure to print out Roush's very detailed instructions to help you get through the job. So if you are looking to enter the world of forced induction, the Roush Phase 1 kit will be very appealing for a couple of big reasons. First and foremost, it's been proven time and time again on the 5 liter platform. It will also be super reliable when using the Roush calibration. And last but not least, it can easily be upgraded if and when the urge for more power strikes down the road. So, that is my brief overview of the Roush Phase 1 kit, which you can grab right here at

        Night and Day

        I have the 3.73 gears in the rear end, and after installing this supercharger even the summer only tires on the back just get blown right off through 1st and 2nd gear. And you can't tell a difference in the driving if you are driving without getting into the pedal. Gas mileage went down just a bit, and don't forget you have to use premium always now. If you want power, this is the way to go.

        Supercharger phase 1 kit

        Best bang for your buck. The power gain feels so good! Better tires are definitely recommend if buying this supercharger. The phase 1 kit is pretty quiet and I can barely hear the whining nose superchargers make so this would be perfect if you want your car to remain a sleeper like how mine is. Only part I do not like is the sound of what I believe is the pulley spinning. Other than that this kit gets 5 thumbs up!

        It completely changed my thoughts on my PP mustang! I bought my 2015 in march 2015. I never wasted a penny or mods because, I knew i wanted a supercharger. I finally saved enough pennies and pulled the trigger black Friday! Got the thing for 6600.00 what a steal. The car is stupid fast literally glad i didn't waste money on intakes and exhaust. Everything else is stock and the car mops up most cars around me! But its whisper quiet. Im thoroughly pleased.

        Had it dealer installed at 2017 purchase. The power is awesome, really spins though in first and second. Bigger, better tires may help! Went From a 11GT Mustang straight to Supercharged 17, big difference. You’ll love it but respect its power.

      I have a bone stock 17 GT with corsa xtremes exhaust. Can I install this supercharger on this car without damaging the motor or any other parts on the vehicle? Will it be reliable to drive every day or maybe even take it out for a race or two?

      • Hey Jacob, The beautiful thing about the new mustangs is you can slap a supercharger on it no problem with out doing any harm to the engine even if you daily drive it. But what you will want to do is swap out the half shafts in the car to adjust for the power. The ones that come stock in the car are weak and can snap simply by doing bolt on upgrades .

      Helpful (10)

      I have had mixed answers to this question. By installing this kit, is it going to void my factory warranty? My 17 GT only has 11k miles and don't want to lose the warranty.

      • The Roush R2300 670HP Supercharger will effect the warranty on the driveline of your Mustang.

      Helpful (6)

      If I get this installed on my 15’ GT will my sport, drag and other buttons/modes still work with the new tune?

      • No, those modes will no longer function after installing the supercharger.

      Helpful (5)

      Can you install this supercharger on a 2017 GT that is an automatic? And besides the halfshafts and driveshafts is there anything you should mod or upgrade?

      • The Roush R2300 670HP Supercharger will fit both automatic and manual transmission models. An upgraded driveshaft and half shafts will ensure reliable performance. Additionally stiffer bushings in the rear suspension will help with launches and reducing wheel hop.

      Helpful (5)

      What other upgrades are recommended to get the most out of the supercharger?

      • Hey Justin, As this is a complete kit this will come with everything you need for a proper installation. Now to get the most out of a super charger you are looking to do some pretty extensive work and modifications and the list can still go on forever. But things you're going to have to do are the half shafts because they'll snap under that much added power (learned from experience), you'll want a new drive shaft as well. Of course a dyno tune and those would be the major changes you're going to want to do right away.
