    5 Top Rated Questions

    Upgraded internals? Would I need to upgrade any engine internals to run this kit, or can it be installed on a bone stock 11-14 gt without any problems?

    • Yes you can run this kit with stock internals. I am running this kit on my 2011 Mustang GT. I ditched the Roush tune that's provided with the kit and ordered a custom VMP tune to maximize this kit. only other mod to my car is a off road H pipe and I am pushing 14 pounds of boost with the kit. My car put down 630 HP and 552 TQ to the wheels on a Dynojet. Keep in mind the Roush tune is very conservative and restricts power so if you wanna play it safe I would stick with the Roush tune. My car has almost 40,000 miles and still have the stock clutch and everything is holding strong. I bought the kit from American Muscle and installation was great.

    If i have bbk long tubes off road x pipe and boss 302 intake will this sc fit with all my aftermarket parts

    • This Roush Supercharger kit would not work with the 302 intake as it comes with its own intake setup. The long tubes will not effect your ability to use this supercharger.

    Does the OEM strut brace need to permanently be removed to install the Roush R2300 Supercharger?

    • Yes it will have to be removed. You can always get an after market one to go in its place like like the 07-09 GT500 strut brace.

    How come the Roush Stage 2 supercharger works with automatic transmission but Stage 3 does not?

    • Unfortunately, Roush Performance designed the phase 3 kit to only work with the Manual Transmissions for the Mustang and at this time they do not offer a phase 3 kit for an Automatic.

      Addictive power! Roush TVS for the win!

      My 2013 Roush Phase 3 TVS car is an absolute animal! I opted to go with bigger injectors (56lb GT500 injectors), colder NGK plugs, a K2 high flow air filter (from Palm Beach Dyno) and I ditched the Roush tune for a FAR superior VMP tune. The power is astonishing for a daily driven street car. Haven’t put it on the dyno yet but it’s easily 600 whp without breaking a sweat. I highly suggest going with a tuner like VMP or Lund, datalogging and dialing your car in. Driveability is spot on, and this thing rips at WOT.

      Raw Power!

      I purchased this ROUSH TVS Blower and all I can say is - WOW! Mind blowing horse power with a Solid History of dependability! It looks fantastic on my motor and you will be amazed at the power gains you get from 3800RPM or higher. I'm putting down 624RWHP and 540TQ to the rear tires and I know she has more! Highly recommend this Blower!

      Great Kit !

      This kit is worth the the money...Roush quality through and through...I am not a mechanic but my friend i helped do the install with is. Our only complaint is the instructions...suggest your read the entire 95 or so pages several times so you know whats coming. They don't come in order, for example you should read page 37 before doing page 34. So, READ first. Must have a good knowledge of connector pinning and re pinning. Trying to find pin number 56 amoung 70 pins on a computer connection is a bit taxing....the one connection took 3 hours....it has to be right. There is a video out there on you tube which is very helpful.The guy who did this in 10 hours must be a mechanical genius...i meant that in the nicest sort of way. Took us close to 20 hours. Take your time, do what it says.....but do your homework first. Fired up and ran perfect first time. Roush quality. Fred G.

      Excellent Kit, high quality with huge performance gains!!!!!!!

      I highly recommend getting this supercharger setup, this is an excellent kit with huge power gains. For over the past 6 months I have been doing a lot of research on what setup I wanted to go with. I finally decided on getting this kit after reading several reviews on mustang forums. Their was a lot of positive feedback on the new Roush TVS supercharger. The supercharger is such high quality that Roush offers a 3 year 36,000 mile warranty. This kit has a standard install time to be around 10 hours. It took me about 15-20 hours to complete the install as part of the instructions was unclear on some of the wiring of the kit and what bolts are to be used in the provided packages. The rest of the instructions are great. These are really the only two problems I had with the entire kit just to show the quality. There was one wiring harness that I could not figure out where to plug it into. The instructions with the kit did not show or tell where to plug it into. I contacted Roush tech support for the first time to try and figure out where the wire plugs into and they advised me their tech was busy and they would half to call me back. I waited a few days and they never called me back. So I tried calling them back and they told me the same thing, that their tech was busy. The very next day I finally talked to tech at Roush and he told me where it goes and it was so easy to find and plug into. I know Roush is really busy so that was not a big issue for waiting. It was a sensor that is hidden back behind the passenger side cylinder head. The wire I am talking about runs from the fuse box under the hood to the intercooler pump and then branches off to that sensor behind the passenger side cylinder head. Now for some of the time consuming task for me that you half to do for the install of the kit. The hardest part of the install is you half to make some grinds and cuts on the front engine cover on the block. I knew I was going to half to do this but I am not real big on doing this as their is no room for mistakes. You have to do this in order to get the provided pulley bracket on and to make clearance for the belt. I used a grinding and cutting wheel to make all this possible. I submitted a picture of the grinds and cuts I made on the studs and ribs on the front passenger side of the engine cover. There are 3 ribs that half to be removed along with 2 studs. There is another stud that half of the width needs to be cut off. You have to be really careful doing this as you can cut and shave to much off the block and cause permanent damage. I really took my time in doing this and I used a Dremel tool to smooth my work up on the block. One of the other time consuming task was de pinning some of the factory wires from the connectors. On a few of the connectors you have to de pin the wires in order to get them into the new provided connectors. So make sure you have a few wire de pinning tools for this kit. If not the local parts stores carry them. Everything in this kit that needs to be bolted on gives you the specs on how much they need to be torqued down. The Roush installation instructions use Nm, which is Newton meters. You can use a conversion calculator on the internet to convert Newton meters to foot pounds. Overall those where the only problems and the only time consuming task I had with the kit. Everything else bolted right up and the fitment of the kit is factory. The kit also comes with the Ford racing 0-degree heat range spark plugs that was not listed in the kit which is great. The Roush fuel system upgrade (boost a pump) install only took me about 20 minutes. I submitted a picture of it installed on my car. It mounts on the driver side of the trunk just behind the rear seat on the sheet metal. You will have to run one of the wiring harness from the boost a pump through the cabin floor board of the vehicle to the engine bay. This is the wire for the boost activated switch that is mounted on the supercharger. This kit also is a drop ship item meaning that American Muscle does not carry this in their warehouse, once they have received the order they will contact Roush and it will be shipped directly from them. If you have anything missing in the kit or problems you will have to contact American Muscle first. For tech support you can call Roush directly. Once I ordered the kit it took it about a week and a half to finally get to my house. Roush also provides a FedEx box for your ECM computer module which is prepaid so you can get your computer flashed at Roush. It only takes a few days to get it back. If you plan on getting a custom tune for this kit you will not need to do this step. By getting a custom tune for this kit you will void the Roush 3 year 36,000 mile warranty. I am very pleased with this product and I highly recommend it. You will be making 12 pounds of boost with this kit, and it really has some good sound features. My exhaust note has changed and it sounds a whole lot deeper and louder. The supercharger has a whine to it at wide open throttle or put into heavy strain. Its not super loud but you can still hear it. I couldn't be happier, this kit is exactly what I was expecting. Thank you American Muscle for the excellent customer service. You all set an example on how a company should treat their customers. You all have always took care of me, keep up the great work!!!!!!!!
