Roush phase ll super charger.
I installed the Roush phase 2 on my 06 G.T. Mine came with the dual fuel pump and a new driver and wiring harness. Everything was pretty strait forward except for the instructions for the fuel pump wiring harness which required some modifications to the factory harness and was not clearly spelled out. It all worked out well in the end. I recommend replacing the radiator and cooling fan to the GT 500 set up. It fit well with a couple of minor modifications. Excellent power upgrade. Clutch will be next.Helpful (12)

Throttle body fit
The elbow supplied from Roush is drilled for the GT500 throttle body pattern. Therefore the BBK 62mm and FRPP 62mm will not fit without a spacer. If you use a spacer, try to find an open one that doesn't interfere with the airflow. The Factory GT500 TB is 60mm and the FRPP GT500 TB is 65mm. Unless you're running a fully built short block and a lot more boost, the 65mm is a waste of money.Helpful (12)

After a couple short rides, my belt was fraying. I contacted installer, and 3 months later they told me it's normal according to Roush! I find this hard to believe, but Roush told me the same thing. Something like that is normal characteristics of that belt on a TVS 4.6l install? I'm looking for a better belt, to try to determine if it's a belt issue or install. All the S.C. car's I see at shows there belts look fine, while I have a rag hanging for a belt! In fact last showing I was at I over herd several people saying it's going to need a belt soon. Well I haven't even ran a tank of gas through it, and it's only seen 4500rps a couple times. So it's not like I'm taking it to the drag strip every weekend.Helpful (24)

Great Supercharger kit
I paid my mechanic to install it on my car, it took him like 6 hours to get it up and running. So far it has been a great experience it offers an enormous amount of power wich was the necessary that I needed. It comes with every single piece that you need screws everything you only need to have the tools which is why I took it to my mechanic.Helpful (20)
So I have a 2008 gt/cs with 60k miles and No mod has been done. Would it be better for me to get this phase 2 kit or just go with the phase 1 kit? I only ask because my internals are stock.
If you do not plan on building the motor and upgrading the internals, I would not recommend the Roush R2300 550HP Supercharger - Phase 2 Kit. Phase 1 would be a better, safer, option in your case.
Hello I have a 2006 mustang gt and I was wanting to get a supercharger, now what all should I upgrade if I wanted to get the roush R2300 Supercharger phase 2 kit? would I have to upgrade anything else, such as clutch and flywheel? or is there more that would be recommended to upgrade?
Depending on what kind of shape your clutch is in at the moment and how you drive determines how much longer it will last. I have been running this kit for about two years now on my stock clutch which was in fairly good shape to begin with and it is just starting to slip now (installing a new clutch as a winter project at the moment). My car had about 60K miles on it at the time of the Roush Supercharger install, and I have always been careful to let the clutch full engage before giving full power, which is probably why it lasted as long as it did. If you are going to be power shifting much at all, you will probably burn the clutch out in no time as this kit adds a significant amount of power over stock. Although the kit does not come with a fuel pump upgrade, I would probably add (I did) a 'Boost a Pump" for insurance (a lot of people go with the duel fuel pump from Ford racing, but is pricey) as the biggest engine killer when going to a supercharger kit is running lean because of inadequate fuel supply.
Is there any transmission work that has to be done to the car or can the stock transmission take the power?
Hello! You will likely need to upgrade your clutch to handle the new power from the Roush R2300 550HP Supercharger
From what I’ve researched, to upload the tune to the car, you have to take your computer out and send it Roush to have them upload your tune, and wait for them to send it back. Is that true with this kit? Or does a tune come with the kit in which customers can upload the tune from home?
You would not need to remove your computer to have the tune loaded. Any local Roush certified dealer or speed shop would be able to load that tune for you. We would recommend contacting your local dealer to see if they or a Roush certified dealer, or contact Roush to see if there are any Roush certified shops in your area.
Ok I need to be enlightened. So I have a 2008 gt/cs with 50k miles and a X pipe and roush extreme cat back exhaust. And that's it. No other mod has been done. Would it be better for me to get this phase 2 kit or just go with the phase 1 kit? I only ask because my internals are stock.
With the modifications you have and using stock internals, we would recommend going with the Roush R2300 475HP Supercharger - Phase 1 Kit- item 42154 https://www.americanmuscle.com/roush-r2300-supercharger-kit.html
This will come with a Roush PCM flash voucher card which will allow your vehicle to be tuned based off of the information that you submit in the tuning sheet when you purchase this supercharger.
Roush R2300 550HP Supercharger - Phase 2 Kit (05-09 GT) will fit with the use of a ford performance twin 62mm throttle instead of the 60mm twin throttle body it comes with.
The Roush R2300 550HP Phase 2 Supercharger Kit does not require any internal changes to the motor. You can install it on your 2006 GT as is!
This can be safely installed on an otherwise stock Mustang. The only upgrade you would want is a better clutch to handle the power.
Additional motor modifications may be needed based on your mods, tune, etc. We recommend consulting with your installer for a recommendation.
This would be done through the tuner and the pulley.
This will be a quite tedious and time-consuming job. We would advise to reach out directly to a local shop that specializes with these types of performance-based builds for assistance.
The hot rod cams can be used with a supercharger, however as they are designed for a naturally aspirated engine, they will not provide the best performance.
