    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?

    JacobJ

    • 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 .

    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?

    DavidS

    • 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.

    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.

    I have a Mustang GT 2017 and wanted to know if I was to put this ROUSH Supercharger on my car would this void my car warranty?

    Brent

    • With the Roush R2300 670HP Supercharger and most Roush products, when installed by an authorized dealer will not void a factory warranty. We highly recommend consulting with Roush and your Ford dealer for more information!

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

    JustinH

    • 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.

    To Clarify......I have 2016 GT/CS with adaptive cruise.....is there a way to over ride or unplug or disable the adaptive cruise control so that a Supercharge can be installed and the supercharger work fine? OR is this not possible?

    RobCanada

    • To install the Roush R2300 670HP Supercharger in a Mustang with adaptive cruise control, the sensors will need to be removed, and a Ford dealer will need to disable the adaptive cruise control system.

      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!

      Roush PHASE 1! BUY IT DONT DELAY POWAAA!

      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.

      Roush Phase 1

      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.

      This S#!T just got REAL!!

      Night and day. Before 6th gear was a dog on the highway and now it's as it should be. The only problem is that my horrible stock bald P-Zeros have rendered 1st and 2nd gear useless. The rest of the gears are a blast. It's so much fun to drive that I didn't want to park it for the night. I know what i will be dreaming about tonight and I can't wait for tomorrow to come. I have Michelin Pilot Super Sports going on next week, then it's time to play in 1st and 2nd gear. Best mod decision I've made some far thanks American Muscle and Roush!

      Warp Speed

      I absolutely love this kit. It retains the stock drivability but when you hit the gas it's like engaging warp speed in the millennium falcon! Also I can get 24-25mpg on the highway. But I'm averaging about 16mpg. This kit absolutely breaths life into your Mustang. Don't waste your money on anything else if you're trying to go fast.

      Just get It

      I bought this one for my 2015 Mustang GT but the only problem is that Roush Preformance took forever to send it out (5 Weeks) and another few days to get it installed. So, if you are patient then go ahead and get it. I Love the supercharger it really made a difference, it fits and performs amazing.

      Superior power!

      Has my 2016 GT/CS fitted with this Roush supercharger and the power is just amazing. Had a dyno on 91 Octane, and still got 592 rwhp! Power is there everywhere, and there is no supercharger whine if you are looking for that type of thing. I get to keep my warranty, highly recommended.

      Fast and angry

      stock the mustang was a slouch no power as everything seems to pass you. Once supercharged you are the king of the sling. went from stock Mild to Wild and loving it. Save your time and money wasted on tunes and cold air intakes and get Supercharged you will not be disappointed this car is a blast to drive now

      Can't go wrong

      I absolutely love this supercharger set up for my 15 gt. Warranty gives a nice piece of mind knowing ford/roush will back it, and they've been more than helpful to call with any questions. It isn't a very loud set up either if your looking for that supercharged whine its not really noticeable. I have had it recently run on dyno, making just over 600hp at rear with this and a catback exhaust running 93! So it makes it a nice surprise to the guy that lines up next you on the street. You will not regret choosing this kit one bit.
