            Performance upgrade

            I found this kit very complete. Fits manual or auto. trans. Parts for both in this kit. Does take special tools a normal person won't have, elect. Connector tool, cutoff tool, and auto. trans.cooler line quick discount tool. After many years turning wrenches had to find a Snap on tool truck for discount tool. All in all, was very complete kit.

            Worth every penny butttt

            They don’t tell you that you can’t upload the roush tune with a handheld tuner.. you do in fact need that special device listed in the product details.. I feel like that part should have been bolder or underlined or made more clear.. as for the fit, you do have to do some cutting which makes it not a perfect bolt on.. also the instructions are a pain and the pictures can be a little more clear.. but the power is unbelievable.. couldn’t be happier

            i was immediately satisfied with the power gains. Went from 390 to 500 hp to the wheel. My only complaint is that it I don't hear a whine very much. i would look no further if you want to go force induction.

            With my long tube headers and custom tune, this car is just an animal. 1st and 2nd gear is worthless unless you've got some good meat out back but 3rd and on is just a blast.

            Extremely happy with this Supercharger and choosing Roush over xyz brand.. Did the install myself, took my time and finished in two weekends. All of the parts, connectors etc. are factory correct so everything looks clean and original. Power gain is incredible. I’m glad I waited to make this my first modification, now I can focus on stance and appearance. Thank you Roush and American Muscle!

            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.

            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.

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!

            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.

            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.

            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.
