Default Roush and GT500 Owners / Drivers Chime In!

Help me make some decisions on my next car here!

I'm in the process of doing my homework on the GT500 and the Roush. For the past year or so, I've been eyeing the GT500 as my next car (current lease is up in four months), but the Roush has really grabbed my attention lately.

They both seem like great cars, but from what I've read, the Roush (427-429R) is more of a well-balanced machine (power, torque, braking, handling, etc) than the 500. The 500 has the edge in straight line power, but all that weight up front seems to get a lot of negative press.

Has anyone owned / driven both, and if so, what is your take?

As an owner of an '07 Roush 427R, I can tell you that you would be very happy if you purchased one. They handle like a dream, and plenty of power. I make custom pulleys for the Roush supercharger and my car makes 495 crank horse ( 421 rwhp ) so with lighter weight, beating a GT500 in straight line power is no problem.

There are some amazing deals to be had on Roushes - my local dealership still has BlackJacks and 428Rs backed up on the lot, with the 428Rs advertised @ $36k, Blackjacks @$43k. Personally, the name turned me off the 428R - a "428" without a 428 engine just seems somehow like false advertising to me. I loved the BlackJack though, which is pretty much the same setup as the 428R, and I was really close to getting one. I finally went for the S302E, but it was a close thing...

What do you want out of the car? If you want unlimited hp potential than the GT500 will be hard to beat. As for handling you "could" make the GT500 handle as well as the roush but it will cost you more in the end. Its going to come down to what you prefer. Two different cars built for two different purposes.

Ideally, I'd like a nice base with as many "goodies" as possible to start with "out of the box," which seems to be the Roush. Other than cosmetic, I can't think of anything else on the car that I would do right away. With the GT500, I'd be looking at brakes and suspension right away, while the Roush already has this. Plus, entry level on a GT500 right now is a few thousand more than a 427R, but you don't get the suspension, brakes, etc., etc. of the Roush.

On the other hand, the Shelby will be worth more in the long run from a collectability standpoint. When I think high performance Mustangs, the name "Shelby" comes to mind.

Are the performance and characteristics on the cars really that much different though?

Out of the box ... off the showroom floor ... yes, but as mentioned, "If you want unlimited hp potential than the GT500 will be hard to beat".

The trend for many first time ROUSH owners, I've noticed, is getting a Stage 3 variant and enjoying it quite a bit in the first year or two of ownership while putting on 'mild' mods. Trying to maximize the ROUSH enhanced Mustang GT for power and some limited handling. But, after reading various forums and seeing the big dyno numbers of the 5.4 or even the S/C DOHC 4.6 .... many owners look to 'upgrade'.

Personal observation, once the owner gets comfortable in the aftermarket upgrading world ... they want to tackle the big boy of the time. During the late SN95 run it was the SVT Cobra. With the new platform, S197, it's the SHELBY GT500.

Take it for what it's worth, but either vehicle would provide great experiences during ownership. The ROUSH family is tight, new and up and coming, whereas the SHELBY contingent is 'well-established' and legendary.

Based on your comments ... I think the ROUSH Stage 3 (any variant) would really fit you well but, dependent on you deepest desires, only time will tell if you make the jump the SHELBY side.

Do your self a favor and don't even consider these cars as investments. If you sell either one your going to lose money. If you want to look at it in these regards you should buy the one you can find at the cheapest price so in the end you won't lose as much dough.

From what it sounds like I would stick with the roush. UNLESS you plan on trying to make some big numbers on the dyno and have suspension and handling in a distant second.

It's a win-win situation.

Personally, I'd go GT500 because Ford hit a home run with the forged 5.4L. It can handle whatever upgrades you can throw at it. Suspension upgrades are cheap compared to how much $ it would take to match the GT500's engine.

My first problem right off the bat with the Roush cars is that they have no book value listed in any of the major pricing bibles, namely NADA. To me, that is ridiculous. I also am not crazy about the 18" wheels and weird (imo) frontends on them.

Even at that..I'd pick a Roush over an 09 Shelby. BUT...thats an 09.

If we are talking about the 2010.....the 2010 Shelby just kicks ***..looks, and I'm sure performance and handling wise from what I've read. I am strongly considering dumping my Saleen and picking up one of these when the time is right. I love the colors and the aggressive stance, and Shelby hit it right with the new body style.

Quality wise, I don't think ANY of the "specialty" Mustang builders hold a candle to what Shelby puts together, whether its an 09, or the new 2010. Also, as Polk said..you aren't going to beat the 5.4 forged motor-it is simply a beast when you start tuning and tweaking it.

I would doubt you'll have to spend much money, if any at all to get the '10 Shelby to handle as well as the Roush..so to me it makes it a no brainer if you can wait till the 2010s come out..

Well, I had a chance to drive a Roush 427R at the dealership this AM (they absolutely refused to let me test drive one of the ten or so GT500s on the lot - oh well), and I was pretty impressed. Very tight feel, loved the shifter (it looks too tall in the pics, but it was just right), and the car pulled pretty well (though I did not get it in the higher RPMs). Downside to the car I tested was the alignment was off (or the steering wheel was crooked!! lol), and it did not have the Roush big brakes. Overall, I was impressed though.

Don't purchase anything until you test drive it. Try another dealer.

Absolutely - I'm glad I test drove the Challenger SRT-8. What a disappointment that car was...

Why wouldn't a dealer let you test drive a car? That's stupid.

I agree... this dealership also had about 10 GT500s on the lot.

The Shelby GT500 is amazing for what it is, a mass-produced, fully-warrantied car with lots of horsepower out of a big (and heavy engine). It has unlimited hp potential, but at a big price. It is very, very nose heavy. That means nothing in a straight line 1/4 mile, but it's a serious issue when you're trying to plow through turns. It will probably hold together better than most Roushes or Saleens (both for engine and body/trim issues) simply because Ford put the time and $$$ into putting together a reliable car that they can sell in large numbers (27,000+ over the first 3 years alone).

But here's my take. Having a Saleen that puts out close to 500hp (at the crank), I think I have pretty much all the horsepower that's practical for street use. For the Roush or the Saleen, you'd likely want a custom tune that gives you better throttle tip-in/response so that you launch off the line faster. You'd probably also prefer 3.73 gears (my guess is the Roush comes with 3.55, although I think the stock 2008 and 2009 Mustangs are now down to 3.31 stock for epa/mpg reasons).

With 500-550hp, and 3.73 or 3.90 gears, you can easily melt your rear tires without much effort. In fact, you may find that it's hard NOT to melt your rear tires without much effort. So what's the point of having 600hp, let alone 700hp or more that you could get with a Shelby? Not much unless you're putting on racing slicks and doing 1/4 miles on a track.

That being said, I'm still considering picking up a 2010 Shelby GT500 (in addition to, not in place of, my Saleen) just because it's such a cheap way to get 500hp and a 6-speed stick. And I like the new sheet metal.

Just my $.02.

I agree for the most part. But, I will only throw in my 2 cents that you can NEVER have enough HP, or HP potential. Afterall, why buy these cars if you can't brag a little?

And, the 2010 Shelby does address the nose heavy issue with re-rated springs and a bigger roll bar I believe.

With rumours of a light-weight 5.0l engine on its way (Coyote), I would be waiting to see how that pans out. I'm surprised that Ford has't revived the "Boss" name yet, and my predicition is that it will be the next-big-thing from (ex)SVT, powered by this new engine - somewhere around 2011.

I would agree, it's the reason why we buy these cars. I have an 09 Shelby GT-500 and I never even like Fords until I drove this thing, I had to have it. The quality alone amazed me and you can just feel the potential by just sitting in it.

Great car and it looks awesome
