ROUSH adds 30 extra HP to ROUSHcharger
Ponies and horses go together, don't they? The tinkerers at Roush decided that their current ROUSHcharger didn't provide enough horses for Ford's pony car, so they added another 30 to the corral. Now, for $5,599, the ROUSHcharger increases the HP of your Mustang GT from 300 to 445. That's a 48-percent increase and 30 more horsepower than before due to a smaller, faster-spinning pulley and altered PCM calibration. The result is the aforementioned 445 HP as well as 418 ft-lb of torque.
The add-on will soon be legal for use in all 50 states, and those who already have ROUSHchargers can upgrade by ordering the new pulley for $389. A polished version of the supercharger is also available for $5,899. Installation won't alter the balance of your Ford warranty, which is a bonus, and the supercharger comes with its own year-long coverage if the manufacturer warranty has ended.

PRESS RELEASE:
ROUSHCHARGER* GETS A HORSEPOWER UPGRADE, CARRIES SAME INDUSTRY-LEADING WARRANTY
LIVONIA, Mich. (October 2, 2006) - ROUSH Performance, America's leading powertrain engineering group, has added an additional 30 horsepower to their legendary ROUSHcharger* system for the Ford Mustang GT; this increases the output of this supercharger system to a total of 445 horsepower under the hood.
The additional horsepower comes from changing to a slightly smaller pulley and an enhanced PCM calibration to take advantage of the higher spin rate. Customers with a previously installed ROUSHcharger* can upgrade to this High Boost Pressure Pulley by ordering part number 402863 which has a suggested retail price of $389.00.
With the addition of the upgraded ROUSHcharger* any 2005-2008 Ford Mustang GT can be increased to 445 horsepower with 418 lb.-ft. of torque. This is a 48-percent horsepower gain over the stock engine's 300 ponies. This ROUSHcharger* system will soon be legal in all 50 states for both manual and automatic vehicles.
"The ROUSHcharger* is one of the most thoroughly engineered and tested supercharger systems on the market," said Jack Roush. "We have several hundred engineers here at ROUSH and utilized their collective knowledge to create a powertrain upgrade that will perform better than expected each and every time you put your foot on the gas pedal. The ROUSHcharger* has been tested following O.E. requirements and we are certain that it is designed to provide years of trouble-free use."
The ROUSHcharger* is also the only supercharger unit that is protected by the industry's leading warranty which covers the balance on Ford's 3-year/36,000 mile factory drivetrain backing, or one year on ROUSH components for vehicles already beyond this level.
The main components include a ROUSH M90 Roots-style supercharger, intake manifold, air-to-water intercooler system, high-flow fuel injectors and induction system. In addition to this hardware, the key to maximizing performance is the upgraded ROUSH PCM calibration.
The ROUSHcharger* is available in the standard black casing (part number 403309, suggested retail $5,599) or a polished version (part number 403310, suggested retail $5,899). For more information, visit www.ROUSHperformance.com and search for these part numbers or look under the Mustang section of the online store.
Based in Livonia, Mich., "The Art of Performance Engineering" takes place at ROUSH Performance. In addition to the array of Ford Mustang and F-150 styling, handling and performance upgrades, a complete line of performance parts and crate engines are offered.

So Does Roush make a Flux Capacitor?

No, but they can sure make an F-150 ugly.

$389 for a pulley?! You can get entire serpentine belt-drive setups for that price...

Wow... 145+ hp for $6000 sounds like a freaking bargain. Still... why is the pulley alone so expensive?

So for a little over $30K and a weekend of work, you can have a GT with 445HP - and Roush engineered improvements.
Bargain of the century.

So what about the fuel/air trim and the internals? I know Ford is NOT sending the car from production with forged internals?

All I know is Roush does work with the computers. Also, if you buy one of their superchargers, they reprogram the car's computer for you. Feel free to correct me but even if you add a blower (from Roush), the vehicle is still covered under warranty.
And if I am not mistaken, even adding a Roush blower to a Stang doesn't require internal parts to be changed out. I do know that you have to change out the injectors. But other than that, it's pretty much a simple drop in kit. Kind of off topic but I believe you can pump the Ford GT's power pretty significantly on stock parts. And seeing as the 4.6L is part of the Modular engine family, I am sure it can handle the boost.

You are dead on. Roush, Saleen, and Steeda all make parts that can push a Mustang well into the 500 hp range without voiding the warranty. They are all pretty much straight bolt on accessories with many dealers selling the parts and even willing to put them on for you before delivery. Granted they charge alot but you can leave the dealer lot with a 400+hp Mustang GT for under $35,000. Not too bad if you ask me.

Curious what kind of hit adding this ROUSHcharger would do for the Mustang GT's real world fuel economy (assuming the driver would drive within the boundaries of the law and common sense). And yes, I recognize that no one would likely care about fuel economy if they're spending almost $6K for +145hp but I'm curious none the less.

Well, here's what the EPA says off fueleconomy.gov:
15 City, 17 Combined, 20 Highway (2008 New EPA measurements)
Not bad for that much power (and I don't think a pulley is going to change that figure...)

Winding Road said their 427R Roush Mustang averaged 12 mpg.
I just love how car companies quote HP at the flywheel and not what actually comes from the wheels.
0-60 is always a better measure of performance:
1. 300 HP in the GT Mustang
0-60: 5.1 (auto) 4.8 (stick)
1/4 mile 13.6 @99.9 (auto) --- Motortrend
2. 427 HP in the 427R Mustang and Rouschcharger (Winding Road review)
0-60 4.7
1/4 mile 13.3 @107.8 mph
make your own conclusion.
TBlueMax 4:45PM (10/03/2007)
Thanks for the info. If that's the current EPA rating, I would suspect real world MPG numbers to be slightly lower. Still, not completely awful for 445hp.

THAT ONE PERSON; ARE YOU TALKING ABOUT A POSITIVE DESPLACEMENT SUPERCHARGER? IF SO YOU BETTER CHANGE THE PISTONS OR THE FIRST TIME YOU PUNCH IT THE CRANKCASE WILL EMPTY IN ABOUT 4 SECONDS AND IT COULD LIFT A HEAD! I'M ASSUMING YOU'RE PACKING 12 PSI OR BETTER!
Reply
That One Person 6:51PM (10/03/2007)
Not quite sure what kind the Roush blower is (it says Roots type...not sure if that matters) but I know all it provides is 5 psi of boost.
On a side note, $390 for an extra 30hp does sound expensive. But there engine upgrades that cost more and don't even provide that much power.
howard 12:10PM (10/04/2007)
THAT ONE PERSON; THANKS FOR THE COMEBACK. THE ROOTS TYPE IS A POSITIVE DESPLACEMENT BLOWER. THE GMC 471 & 671 ARE BOTH ROOTS TYPE. BUT, YOU SAY ROUSH IS ONLY PUTTING OUT 5 PSI OF BOOST? I WOULD LIKE TO SEE THE SPECS ON IT, THAT DOESN'T SEEM TO BE ENOUGH FOR THE POWER INCREASE THEY'RE CLAIMING. I GOT A 40% INCREASE IN A 1973 CHRYSLER E-CLASS WITH A 1.7 4 CYL SOC. WHEN I SHOWERED DOWN ON IT AT 40MPH IT WOULD LIGHT UP THE FRONT TIRES. I'M GOING TO GOOGLE ROUSH AND SEE WHAT I CAN FIND OUT, 5 PSI JUST DOESN'T SOUND RIGHT! THANKS AGAIN.
howard 5:16PM (10/04/2007)
THAT ONE PERSON; I NEED TO CLARIFY SOMETHING, THE 1973 CHRYSLER HAD A FACTORY STOCK TURBO WE PUT ON THE 1.7 ENGINE. WHEN I SAID IT WOULD LIGHT UP THE FRONT TIRES WHICH IT DID BUT, ONLY WHEN I DISCONNECTED THE WASTE GATE AND RAN TURBO FROM THE GET-GO. I ONLY DID THIS TWICE BECAUSE I KNOW WHAT WOULD HAPPEN IF I RAN IT ALL THE TIME! TOTAL ENGINE FAILURE. I PUT 189,000 MILES ON IT BEFORE SELLING IT TO MY YOUNGEST SON, HE GOT ANOTHER 85,000 BEFORE BURNING A HOLE IN A PISTON. HE CLAIMS HE WASN'T RUNNING WITH THE WASTE GATE DISCONNECTED SO WE JUNKED THE CAR RATHER THAN REPLACE THE ENGINE. JUST WANTED TO CLARIFY THINGS!
That One Person 4:43PM (10/04/2007)
Howard...according to Roush's website the blower puts out only 5 psi. But I will try and look into it.
I am not really good with the whole blower and turbo tech but from my understanding is that you don't need as much PSI with a blower as you need with a turbo.
Rob 4:04AM (10/04/2007)
$390 for 30 hp expensive? Not at all. I know people with 4 bangers that spend $600 on a cat back and $150 for a CAI for a grand total of 11 hp. But I dont usually look at the money spent, I would cry. I had a kenne bell 2.2 on my 03 cobra, then went to a garrett t76gts turbo in a period of 8 months. The turbo has been in for 5 months and I want a KB 2.8 now, I dont like the turbo. At least it sounds cool but I'm counting down the days till xmas.

THAT ONE PERSON; I TRIED TO FIND A LITTLE ARTICLE I HAVE SOMEWHERE CALLED "BLOWING UP A STORM" BUT HAVENT FOUND IT YET, IF I DO I'LL SCAN IT IN AND SEND IT IF I CAN GET YOUR E-MAIL OR I''LL SEE IF I CAN GET AN ADDRESS TO TELL WHERE TO GET IT. IT'S WRITTEN SO THE NOVICE CAN UNDERSTAND THE PRINCIPLE. I RAN A S.C.O.T BLOWER ON A 46' FORD I BUILT UP. THAT'S WHERE I FOUND OUT ABOUT CHANGING PISTONS. THE FIRST TIME I PUNCHED IT IT BLEW THE TOP OUT OF # 2 PISTON, WHAT A RACKET. THEN I TALKED TO THE S.C.O.T FACTORY IN ENGLAND AND THEY SUGGESTED I PUT IN A SET OF "POTVIN BLOWER PISTONS" WHICH I DID AND YOU TALK ABOUT A SWEET RUNNING VEHICLE. ON THE WAY TO THE BEACH ON DAY MY YOUNG SON DAN, 4 YRS OLD WAS STANDING ON THE BACK SEAT LEANING OVER THE FRONT SEAT BACK SO HE COULD SEE. A PICK UP PULLED OUT IN FRONT OF ME AND RATHER THAN HIT HIM I PUNCHED THE ACCELERATOR AND WENT AROUND HIM, MY SON ENDED UP ON THE PACKAGE TRAY BEHIND THE REAR SEAT BACK AND, THAT WAS IN THIRD GEAR. I WAS PACKING 12.8 PSI. I THINK S.C.O.T. STANDS FOR "SOCIETY OF COVENTRY TECHNICIANS" BECAUSE THAT'S WHERE THE FACTORY WAS, COVENTRY ENGLAND! THE BLOWER LOOKED LIKE A MINITURE 671 GMC AND IT ONLY HAD TWO BLADES ON EACH IMPELLER UNSTEAD OF THREE AS THE GMC HAS BUT, IT'S BEEN A LONG TIME SINCE I PLAYED WITH BLOWERS. I COULD GO ON AND ON BUT I BETTER PUT A CORK IN FOR NOW.
