    Unleash 292 More Horses. The stock 2015-2017 5.0L 4V Coyote powered GT Mustangs come with an awesome 435 Horsepower and 400 lb/ft of Torque from the factory. However, with a Roush R2300 Phase 2 kit installed on your GT the power numbers jump to an astounding 727 horsepower and 610 lb-ft torque, that's 292 more ponies over stock!

    Monstrous Blower Kit, Roush Style. This complete package transforms your GT into a track-shredding beast. Kit comes complete with a 2.3L TVS® supercharger with black finish, upper and lower intake manifolds, an air-to-water intercooler, a low temp radiator, an oversized coolant degas bottle, a ROUSH® cold air intake system, a twin 60mm throttle body with matching spacer, an 80mm supercharger pulley, Phase 2 specific hi-performance Motorcraft spark plugs, Preset Plug & Play Digital Fuel Pump Controller and unique ROUSH designed fuel injectors.

    I want to keep the rims 20's what are the best set of tiers I can get when I install my R2300? I do want the rear 305 if possible. please help!


    • Well for the rear tires you want to go as fat as possible. Depending on your backspacing/offset you may be able to squeeze 315s, but a 305 would fit no problem (and still PLENTY fat). However, if your Mustang has lowering springs, anything bigger than a 275 would require measuring, or be a lucky guess, if you wanted it to fit without rubbing. The front tires are less important in terms of traction and you can certainly buy according to your desired look (just don't go too thin!). Personally I think a 255 is perfect, and if you Mustang is lowered that's probably as big as you can get up front. 275 if it's stock height.

    RE: Rough 727HP Supercharger kit on the ‘15 Mustang GT Premium with PP. Any “Recall” factory update list verification “gaskets water pump. Head temperature variance; and or, exhaust back pressure change by x-pipe replacement of resonator effects to CPU tune upgrade.” I’m able to monitor my head temps already. Roush is not recommending any fan, grill or water pump upgrades to be mandatory. Does a x - pipe update effect the back pressure off setting the new tune program of the Roush 727hp Supercharger kit?


    • Depending on what x-pipe you go with, as well as if it has catalytic converters or not, can definitely affect the tune that is included with the Roush R2300 727HP Supercharger.

    With this kit what kind of fuel/octane can I use?


    • This kit requires the use of premium fuel (91 octane and up). With a custom dyno tune, you may use some alternative fuels such as Ethanol 85, Ethanol 90, etc.

    My 2016 GT Convertible has Kooks 1-7/8" Catted Long Tubes and Magnaflow Street Catback already installed on it. Will Roush be able to flash my PCM for this setup if I send it in to them?


    • Hey! The Roush R2300 727HP Supercharger - Phase 2 Kit PCM flash is a base tune. For custom tuning, you would need to consult with a tuning company.

    The Roush 727 hp kit in three boxes just arrived. My question I wrote down was to be sent to Roush pertaining to the cpu flash tune. I did not want the “Adaptive Cruse Control” to cause a accident. Turn it off? I found the fix in the 2015 Mustang owners manual on page 5. You can manually change from “Adaptive” Cruise Control to “Normal” Cruise Control through the information display driver assist. The display icon will change.

      Had the Roush R2300 Phase 2 (727 HP) installed by an authorized dealer on my 2015 GT Premium. You can't tell it's there by listening for it. My GT is 100 stock except for the SC. Normal driving fuel economy is spot on to stock. With that said, you know it's there when you put your foot down. When the R2300 tips in, you better hold on and be ready to shift! It is an absolute beast. As an added note, on my Premium, the boost and A/F gauges in the info display Gauge setting worked without modification. Read 10psi boost and between 9.5 to 12.5 AFR, depending on what gear and load I was in. Those "free" gauges are big plus if you decide to add a Roush blower. I can recommend that you do. You won't regret it!

      Mind blowing speed... completely speechless! This car is faster than anything I've ever driven now. I have no regrets thus far. Can't wait for summer fun. I had installed at dealership I purchased from. Great decision, since there happened to be a recall one my door latches they took care of at the same time.

      Enough HP for now

      I had this Roush phase 2 installed with some other exhaust and suspension goodies new at Ford dealership on a brand New S550 GT and I am plenty happy whenever I get in and drive. More power than I could ever need but not too much to handle.

      Amazing power!!!

      The power from the phase 2 supercharger is absolutely amazing. The install went well other than the instructions were not always very clear. Would recommend watching the videos of ailable on YouTube and there´s will help you out significantly. There was absolutely no reason to remove the water pump and I was able to install it just fine without doing so. Highly recommended.

      Awesome bang for ur buck !!!

      Everything was installed like a glove. No problems. Can't believe the throttle response is instantaneous, and the added horse power is a major plus and very gratifying. Worth every penny !!! 0 - 60 in under 3 seconds. If anyone interested in getting one. I suggest u go to CJ Pony and get the eco boost cluster gauge.
