will stock bottom end work with this? will i need to get a rebuild kit for the bottom end or will the stock internals hold up the the HP produced by the super?

Yeah keep the at 8-10 p s I
You are safe with this kit. Now if you upgrade the pulley and start pushing more boost, you will start to push the line on breaking something. You would need to upgrade the fuel pump setup for anything over this kit.
Stock internals will work fine as long as you don't try to change pullies or otherwise run more boost than what the kit produces. I do, however, recommend adding a GT-500 dual fuel pump for added insurance. Run a forced induction engine lean, and you're looking at a rebuild at best and a new block at worst.

Headers A question and a comment. I read a review saying this will not work if you have headers without a custom tune. Is that true? If so I will probably find a different supercharger since places around here that can provide decent tunes are few and far between. It's hard to believe Roush has never encountered a car with headers before with one of their superchargers. Ugh!

Roush ONLY writes tunes for stock engines. I wrote the review you're talking about, and before I bought this blower I specifically asked Roush this question. After extensive research, I discovered that the best option is to contact JDM Engineering, as they can write you a custom tune for whatever combo you have. According to them, Roush writes their tunes to be as safe as possible, so there's a lot of power left on the table. JDM has extensive experience with tuning RoushCharged vehicles, as 1. they helped Roush develop their first tunes for these blowers and 2. they have a 4.6 3v RoushCharged Stang that runs 8s! Also according to JDM, RoushCharger plus headers plus their tune will equal around 500 REAR WHEEL horsepower! Oh yeah, one last thing: if you go the headers/JDM tune route, make darn sure you have a GT500 fuel pump installed. Good luck!!!
Its has nothing to do with the supercharger... ROUSH provides a tune with this supercharger kit and it is designed to work with a stock motor. ROUSH does not do one-off custom tunes. They are OEM. Since you have headers, you should be running a custom tune. All you need is to have your current tune revised for the supercharger. There are a lot of changes, new injectors, new MAF housing, etc... New tune is required!!

The Roush R2300 475HP Supercharger will allow for wine at stock boost levels, however it will not wine as loud as higher boost superchargers.

Will u still be able to use ur old BBK 62 throttle body with the supercharger? I have a 62 BBK throttle body and don't want to wast it is it possible to still use it with the R2300 supercharger

No, the ROUSH TVS includes a GT500 throttle body. This supercharger only accepts GT500 sized throttle bodies.
Your throttle body would become obsolete with this super charger.
Nope, sorry!

Can this Supercharger be ported and will i get significant HP gains if i do port it? like ive seen some Eaton superchargers on Cobras get ported and become different beasts, I feel like I'd like to get 500 hp like the FRPP whipple S/C but cant afford it, so I figured buy this one and maybe get it ported? thks 3 answers

Yes they can be ported but not like the old eatons, the TVS are much more efficient and by just swapping the pulley to get more boost is enough to get higher horsepower levels without the need to "port" the blower...
I have a 2008 roush stage 2 Auto trans will the phase 1 kit fit my my pony
I was told YES. The R2300 is an upgrade to the stock GT500 supercharger. There is a company that buys this supercharger then ports and polishes it.

Will this kit fit under the Ford Racing Strut connector on a 2009 Bullitt I am looking to add this to my 2009 Bullitt. Does this charger need an additional fuel pump? Any dyno results? O.K. to add to a car that has 50,000 miles? 2 answers

There are a few things you need to know before moving forward. 1) Has the car been modified from stock configuration? i.e... does it have headers? The Roush system is FANTASTIC if you have a stock car. When you send the PCM to Roush they assume the car is factory. If you have added headers you will need a GT 500 Fuel pump kit, and a tune on a dyno. The best thing to do is to weight the options. I had to get a tune since I have Kooks headers; it needs the GT 500 Fuel pump kit and a retune. I also was able to us the GT 500 strut bar. The kit is mainly Ford Racing GT 500 parts with an Eaton 2300 SC and a Roush intake. I love it and would go and do it again if I had too, just would be a little wiser with the other parts needed. Oh, and if it is modified.... Don't send the PCM to Roush get it tuned on a dyno...
First, NO, this supercharger will not fit under a cross brace. Hood clearance once installed is VERY slim. Roush says you don't need to upgrade the fuel pump, but $750 for a GT-500 dual pump for extra insurance is a lot cheaper than $3-5K for a new motor. Plus, the GT-500 pump will readily support just about any other upgrades you can throw at it. My Mustang had 65K miles at time of Roushcharger install. Granted, it hasn't been on my car long but I have made a few 400 mile trips with it already, with no problems. I will try to get you some dyno results when I get my car custom tuned so I can add headers.

If I purchase the Supercharger with my mods like cams, cold air intake, sct tuner, bbk pulley, x pipe exhaust with no cats and 373 gears would I have to change or upgrade on any other parts? What about internals? It will be a daily driver. 1 answer

Modified vehicles will not be supported by the included tuning. A custom dyno tune will be required. Additionally depending on your power level, further fuel system upgrades, as well as a stronger clutch for manual transmission cars may be required.

I live in NJ and have a custom tune. To pass inspection I have to put my stock tune back on because your not allowed in NJ to mess with the pcm. So my question is how does the tuning process work in order for me to pass inspection? Would an inspection station pick up the tune and fail me? 1 answer

The tune included with this supercharger would not show up as an aftermarket tune to any emissions testing equipment, however depending on local emissions laws, and the specific tune written, your car may not pass emissions. We recommend consulting with Roush about your specific setup.

Will a hand held tuner from Bama be able to tune for this and multiple other modifications until I finish my build getgo get it dyno tuned? 1 answer

The handheld tuner device can load custom tunes that are specific for that Roush R2300 Supercharger. However, Bama Performance will not custom tune for Forced Induction applications so you will need a tuner who specializes in tuning for supercharges such as VMP Tuning for example.

Only way to get POWER!!

Don't bother with a stupid waste of money tuner thinking you're all that because you have a "custom tune" The only way you're going to get real power is by a supercharger or a turbo. "Hey bro, I got a custom tune on my stock mustang. Feel how much faster it is?" Don't been that guy...

2008 GT with Roush 2300 Super Charger upgrade

I am disappointed that after paying $56xx. for the unit that I had to pay for FEDEX shipping and return shipping my PCM to Roush for programming plus I had to pay $100 for that programming. After these add on epxenses the Edelbrock E series might have been a more reasonable choice.... Beyond this I am extremely pleased with my 2300, my 3v GT really responds to the new HP upgrade. The quality of the product and the fitment is great. AM needs to change out the product picture on their website because, my unit anyway did not come as pictured with the carbon fiber air inlet.

Roush Performance!

Kit is shipped in three big boxes. Quality packing materials are used to keep everything secure. I installed this kit mostly by myself. I had a buddy come over on the last day to help finish up. I wanted to take my time and enjoy the installation. Took me 7 days total. I had under drive pulleys so I had to re-install my original crank balancer. And I took my time with the wiring. You have to unwrap the wiring looms, being careful not to cut the wires inside the bundles. I soldered all connections and re-wrapped everything tidy and neat - factory looking. The kit instructions are very good. Could they be better? Yes, absolutely. There are a few steps that are very incomplete, or missing, but patience will get you through it. There are extra parts included to cover the different years, don't freak out. I have an automatic. The kit installs the same as a manual car. Roush did not spend the time to offer an automatic car tune, that's all. I am running an after market tune since Roush doesn't support automatics. Fitment and part quality are exceptional, it's a first class kit. I did have to modify one wrong style fuel injector clip. I also have BBK shorty headers. There is a passenger side heater bracket that is mounted with a large bolt. By cutting this bolt I was able to mount the bracket and keep my headers. The install is straight forward if you take your chill pill, don't get excited or get in a hurry to finish. There are a lot of steps. Be sure you have a couple of tables to lay your parts on, both the new ones and the ones you take off - super important! Keep your work area organized. Use a shop vacuum to keep engine area clean and coolant free. Be sure to use lots of zip ties, electrical tape, install a boost gauge, buy quality coolant, use Vaseline on rubber gaskets and hoses. Use a tuner who will tweak it using data logs - no one size fits all tunes. Removing the bottom radiator hoses is no fun. And dealing with the hose clamps will drive you to drink heavily. I found a perfect long nosed vice grip as my savior for them. Don't use screw hose clamps. You'll need a hack saw and file for a couple of steps. Car is amazing afterwards. Only WOT at the track for me. Oh and you'll need big wheel and tires!

No other mods compare

Had this installed and chose a custom dyno tune rather than the included conservative roush tune. Total for install and tune was about 1200. If you are considering a mod to make your mustang faster other than this blower I would say if at all possible wait save and get your car supercharged. My car had no go fast mods at all. I focused on the exterior and waited. I couldn't be happier that I did. Car is like the exact same car. Unaltered under stop and go conditions. When you want boost though it's there instantly and the car pulls like an absolute monster. Put down 452 RWHP and 417 RWTQ. That was with the included phase 1 105mm pulley at a max of 6lbs of boost.

Roush Power and OEM Quality

After suffering a humiliating defeat to my buddy's Coyote-powered '12 GT/CS, I decided to do something about it. After considering many options, I settled on a Roush supercharger. I have stock internals, so I figured the Whipple would be a bit much...plus, what Ford guy doesn't like Roush? I had a tough time deciding between the safer (less boost) M-90 Roushcharger and the R2300, so I called Roush's tech line. The tech told me that while I would like the performance of the M-90, the first time I encountered a Coyote 5.0 with cold air and a tuner, I would be upset because I would lose to it. Further, the tech told me that there was nothing else that could be done to the M-90 to upgrade it. Meanwhile the R2300 could be upgraded to Stage 2, 550 hp 500 lb-ft if I decided to get forged internals down the road. Well, alright then. R2300 it is. Things to be aware of with this kit: 1. You have to send your PCM (computer) to Roush to be tuned. An overnight box comes in the kit. I got my supercharger kit in on Wednesday morning. sent the computer off Wednesday afternoon, and had the computer back from Roush Friday morning. The computer comes back with a set of colder heat range olugs to prevent detonation. 2. You cannot have any aftermarket parts. Underdrive pulleys kill boost and prevent proper belt tension. Headers will lead to a Check Engine light and dangerous conditions for your engine. Any non-stock parts other than upgraded coil packs and catback exhaust will require a custom dyno tune. 3. You will need a grinder, band saw or chop saw to cut metal, and a good jack with jackstands for installation, as well as some good torque wrenches. The alternator's upper bolt tabs have to be cut off for repositioning the alternator. A small tab on the passenger cylinder head has to be ground down for belt clearance. 4. You will probably need some extra hose to more easily mount and route the intercooler, as well as some plastic body clips to replace all the ones in the radiator cover and fender liners you will invariably break during installation. 5. Personal installation can be done, but it WILL take a while. I installed this supercharger kit myself with some off-and-on help from friends. it took probably a total of 30 hours for us to install the supercharger. It's a very involved process, and there's a lot of wiring and hose modifications necessary that many people will find too tedious. My ONE complaint about the R2300 is the hardware packaging. Hardware for several different parts is packaged together, and it is VERY hard to figure our which bolts go where. Having a better organized hardware packaging system would have probably cut our install time by a third. One thing I was really impressed by is how comprehensive the R2300 kit is. It even comes with a new belt tensioner and a GT500 throttle body, among other things. Very few stock parts are reused. The instructions are very thorough, I just wish they had a bolt chart in them. Now for the fun stuff...this blower will give your Stang quite a major boost in power, no pun intended. Even better, if you did not know a blower was on your car, you would never suspect it. Even at WOT the supercharger is pretty quiet, with almost none of the blower whine Terminator Cobras are famous for. Since the supercharger install, my car runs like a dream...it's FAST, it's even easier to just cruise around town in than stock, and I'm still averaging between 24-27 mpg on the highway. Hard to beat that. If you are considering a positive-displacement supercharger, the Roush R2300 is a very good buy. I wish the supercharger had been the first thing I bought instead of messing with bolt-ons. You will NOT be disappointed.

Plug and play?

The kit is great! Needs better packaging, it's somewhat organized but screw/bolt/nuts are mixed. Someone needs to contact Roush and tell them to add a few more bands around the intercooler box, UPS tore to side of box up and almost lost the intercooler during shipping. Now about the "plug and play" feature. You have to cut 7 wires and solder on the extensions Roush supplies. Sorry, but that's not "plug and play"! The longer bumper bolts for the low temp radiator need to be about 5 mm longer. The kit is a good kit but could be better with a little more thought on installation hardware. The large bolt that holds the two cooling lines along the passenger valve cover will not fit if you have the BBK tuned shorty headers, go figure. And finally, if you have to buy solder to complete the wiring, make sure you get solder with some "lead" content! It will save you a bunch of time, do NOT use crimp extensions.
