    Installation Do you need to have the phase 1 kit install first before you install the phase 2 or can you just go straight to phase 2 on a stock 5.0 gt

    I read that this kit does work with the SCT Tuner. Is this correct? If i install this, is my car derivable to the tuning shop?


    • Roush R2300 625HP Supercharger - Phase 2 Kit comes with a tune voucher. You have to take it to a dealer and have it tuned before you drive your mustang. You will not be able to drive until it is tuned.

    Supercharger kit I want to buy the roush sc kit stage 2 for my gt 2013. I already bought the sct ifx tuner and free tunes. Can I tune my mustang after installing the sc with the cst tuner and bamma tunes or watha do I need to do to reprogram my car


    • Don't do it. I purchased a the Phase 2 kit and Bama and SCT have not been able to get a tune to load correctly, been almost a month so far.

    If this kit works with a auto trans would I need a shift kit for my trans ?


    • Installation of the Roush R2300 625HP Supercharger would not require any transmission modifications.

    Why won’t this fit a boss 302? You have to take the manifold off anyways to mount the supercharger


    • The Roush R2300 625HP Supercharger can be installed on a Boss Mustang, however tuning support would not be provided, as Roush does not test for this setup.

      Everything I was hoping for

      The fit and finish is perfect, completely indistinguishable from factory - just looks like it belongs there. I haven't modified from the included Roush tune and it fires up and runs perfectly from partial to full throttle. Its the smoothest tuned car I've driven that includes a major/none-factory power adder. Most importantly it now pulls likes it's possessed. Even with 305 DWs on the back you can just roast the tires in 1st and 2nd if your not careful. 3rd gear is straight giggle inducing.

      Kit is worth every penny! Came with everything minus a catch can (which I highly recommend only for passenger side. AM sales is also). Car made 592whp and 500tq after tune. I cant be any more impressed. Highly recommended for anyone who wants to go boost.

      Sick Power

      Im like a kid on Christmas morning every time I get in this car now. The sound when you get on it is so sweet! The power is definitely more than I expected. If it hooks, hold on. Rear wheel hp with custom tune is 565. Cant wait to bolt on the drag radials and see if I can get kicked out the track.

      I had this installed in my 2014 GT and could not be more pleased. The power is carried through all gears and works great as a daily driver. With this supercharger and Borla's S-Type catback exhaust, my car now sounds and performs like a BEAST!! DYNO results were 574 HP and 444 TQ to the wheels. Recommend this supercharger for anyone looking to make your stand a screaming pony!

      Awesome Power!!

      Installed this TVS R2300 on my 2012 GT and the first words that came to mind after a test drive was AWESOME!! This twin screw blower makes fantastic power with my Coyote motor! If your thinking about getting a Supercharger for your S197 - think no more as this is a SOLID upgrade that will blow your mind! I'm at Phase II and I'm at 605RWHP and can spin my rear wheels at 70 mph in 4th!!! Love this Supercharger and it will hold the value due to it being ROUSH!! Fantastic upgrade and I promise you that you will love your GT even more once you install this blower and stred some tires!!! Every cars show I attend people are asking me questions and taking pictures of my engine compartment! This is a SOLID upgrade for POWER!!! GReat job AM and ROUSH for a GREAT product! Very PLEASED with this investment in my power mods!!!

      Super Fast...

      I added the Roush Phase 2 on my 2014 auto. I had the Ford dealership do it, plus I got the three year warranty. The car launches incredibly fast, sounds like a race car with the Roush axelback. The only drawback is the stock suspension has a hard time handling all that power. When you floor it you better hold that steering wheel tight!

      Roush and American Muacle hit a home run

      Wow, the end result are night and day!! Much more power than most streets can hold. The car keeps pulling and pulling but you don't loose drivability on the street. The install wasn't bad at all. The de pinning and grinding of timing cover take some time but nothing to be afraid of. I recommend downloading the instructions. The printed ones are hard to see pics in some spots. I also love how everything looks OEM. Can't beat the look and performance of this kit. To top it all off Amercian muscles priceing and service was top not as always.

      Feels like Mad Max!@#$/

      First thanks AM for the good price and thanks to Roush for a great product. The kit is very high quality. The instructions take you by the hand. I installed it myself in a couple weekends. Was it easy? NO. What it hard? NO. It's doable if you have the desire. Then again I'm a mech. As far as performance. I love it... Very drivable at an easy pace. But when you punch it make sure you're pointing in the right direction. Great fun.

      First, if you are going to go this route? Have the folks at Roush do the install. SUPER bunch of guys w/excellent service and the experience to do it right! The power difference is awesome at higher rpms and going from 65-130 is mind blowing. Highly recommend the kit and a Roush install.

      Best upgrade EVER!!!

      This is an awesomely amazing upgrade. So much power, it really transformed the car! At the same time I did this I added Brembo brakes - figured going fast necessitated stopping fats as well! Have not had the car dyno'd yet but I have no reason to believe the HP gains are anything but true.

      As expected great increase in HP and it looks absolutely beautiful in the engine bay. With the conservative Roush calibration I dyno'ed at 538 HP / 442 TQ.
