Not a bad price but I probably would have went around 3k which is half of what a new one is before install. Buying it used you will not maintain any warranty on the car and are stuck with the limitations of the Roush. Limitations are not an issue if you aren't looking to squeeze as much HP out of it as you can.

 

It is conventional wisdom to knock the Roush as offering limited HP, but keep in mind that the PSI is set by Roush at only 6 PSI, even with the pulley upgrade. In my car with an upgraded exhaust, that gets me just short of 400 HP at the wheels. All the claims I have seen about higher horsepower from other blowers involve PSI significantly higher than 6. And keep in mind that the higher the PSI the greater the risk for engine damage.

When we get into these discussions about which supercharger is more powerful, it always seems that folks overlook that PSI seems to be the main factor driving HP -- the higher the PSI the more HP, no matter which supercharger you have.

 

That's true, but the KBs and Whipples are significantly BIGGER units too.

 

Which is the reason they can be pushed well past what the stock bottom end on the engine can handle. With a CAI and a custom tune people with the Roush (M90 version) are getting around 430 RWHP. yes that break your warranty but all the other break it as well (except the Saleen now?) Fords FRPP/Whipple has a warranty but it is not the HO kit and it's not intercooled thus it's only putting out a low PSI like the Roush tune.

It all depends what you want. Are you a HP junkie where 10 HP means the world to you? If so then go with KB so you can tune it to the moon if you wish but if your warranty is important, look at the Roush, FRPP version of the Whipple, or the Saleen if it does indeed maintain your factory warranty

Of note though on the FRPP-Whipple, if you get it for the warranty, you could always convert it to the HO kit by adding the intercooler and other parts as well.

Oh yea, Roush does have a new unit coming soon or maybe it's out already. It's on their P51 model and is bigger then the M90 that is on mine and the other Roushes. I have no idea how it does or will measure up to the other larger units out there.

 

Don't count the Roush out just yet...

Thanks, that is the video I saw before. People here seem really down on Roush, was just wondering why. Everything I see about their vehicles seems to indicate they are good at what they do, and most do not have more than the standard 435 hp from the Roushcharger setup, right? Plus, they seem to be less expensive, which I like. I had a chance to get a 427R, but the convertable was a little much, and I just need an open top!

 

I personally like the Roush better than the Saleen but what doesn't make any sense is that the Saleen has more power and less weight, how could it be slower?

 

The answer is simple. They lie. The deflate the weight and inflate the horsepower. They always have. There is no Mustang that weighs less than 3400 lbs, especially after adding a supercharger, 20 inch chrome wheels, a bodykit, and an exhaust system with half again as much tubing as the original.

 

That is mostly because of how much HP you get for the cost you pay. The Roushcarger is good, it's been around for a long while, in fact the same technology from it was on the old Thunderbird super Coupes if I am not mistaken.

Tha main reason people buy it is for the warranty and a little extra fun factor for an everyday driver. Most of the people on here that "bash" it if you will prefer something that can be tuned to much higher levels. That is what you need to ask your self. With warranty intact is 445 HP (around 380 at the wheel enough)? If not don't get the Roush. I can tell you that even with mine putting 380 to the wheels, I want more. I don't "need" more it's plenty of power if not to much for the street but I am used to it now so it doesn't feel as fast. I have no worries about my warranty eother.

Now with that said, I have two options when my warranty is done. I can get a CAI and custom tune and get it around 430 RWHP (I think that's close to or over 500 HP) which is still somewhat safe for the stock internals or, I can take it off and put something else on that will give me more. More then likely I will just go with the CAI and tune.

If this helps you any, I did not pick the Roush, it picked me. The car was the last 5 spd manual left from Central FLA down when I went to buy it and it had the charger on already. Oh yea 0% financing had a little to do with it too. But if I was to do it again, I would not have chosen the Roush if it wasn't on, I would have went with something else that I could tune to more power later but that's just me.

 

That is a great alternatiev IMHO. Is that offered on the FRPP website? Do you have a link to that?

I would also like to find documentation on the warranty for a Saleen, if installed by a Saleen dealer.

On the Roush warranty, I called them and the warranty is for what is remaining of the car's original warranty, so if you put the Roush SC on an 06 with 37000 mi, guess what? No warranty remaining. I specifically asked that question, because at first I though: "great! I'll slap that on whan my car has 60k mi, and I'll be covered up until 100k mi", but that's NOT how it works.

The Whipple installation will replace your original drivetrain warranty with a 12month/12,000 mile warranty.

You'd probably have to call Saleen for documentation. It works just like the Roush warranty - they pick up the remainder of your 3/36.

 

Hmmm, I didn't realize it switched it to a 1/12000 deal.

Roush's replaces the 3/36000 or the remainder of it if you still have time left on it, it does not extend it. You would also need to have a Roush dealer to the work if something was wrong.

I was told my the local Ford dealer here who is not a Roush dealer that they can do any work that is not deemed to be caused by the SC but if there was an issue with the SC or it caused a mechanical failure then I would need to take it to the Roush dealer to have it worked on. Of course if your local ford dealer is a Roush dealer then it's no issue but for me the closest Roush dealer is 65 miles away. It's also transparent to the customer. If it's warrantied and it's not related to the SC, Ford gets billed. If it's related to the SC the Roush gets billed. You as the customer doesn't see any difference on your end. It's all in who gets the bill.

 

Sounds like Roush has different policies than Saleen (or maybe that particular dealer you spoke with has a problem dealing with Roush). We have no Saleen dealers here. My regular Ford dealer just gets reimbursed by Saleen instead of FoMoCo for any work. It's never been an issue for me. I don't even know what they have to do as far as paperwork/authorization. I'd think Saleen would contact me or have something for me to sign to make sure some dealer isn't scamming them, but they never have yet.
