There are now three supercharger brands available for the GTO. Each one has it's own benefits so this info should be help you decide which one is right for you -

Vortech



The addition of the V-2 SQ S-Trim supercharger will increase horsepower from 350 to 481 and torque from 365 lb./ft. to 435 lb./ft. at 7-8 psig at the flywheel.***

The system includes an integrated dual-pass air/water charge cooling configuration, which features a closed loop water cooling system with a stand-alone pump, tank and front mounted heat exchanger. All components needed to bolt the system to a stock vehicle, such as billet aluminum mounting bracket, fuel system upgrade including replacement injectors, supercharger oil feed and drain, compressor bypass valve and all required fasteners are included. The installation allows retention of all factory accessories including A/C and power steering. This system is available in satin or polished finish. The V-2 supercharger is covered by a three-year limited warranty.

*Legal in California only for racing vehicles which may never be used upon a highway.**6-Speed system to be released by the end of September, 2004.***Supercharged horsepower and torque data shown is a calculated estimate based on percentage increases from actual rear wheel hp/tq measurements.

ATI ProCharger








The new Intercooled ProCharger system for LS1-powered 2004 GTO’s produces a 50-55% power gain on stock motors running pump gas, with 7 psi of intercooled boost. This compares to competing systems which produce 29-37% horsepower gains with the same 7 psi, but without ATI's superior supercharger and intercooler technology.

This system installs in approximately half the time of other systems, with no need to punch a hole in the oil pan, replace the engine intake, or deal with all the complexity of an air-to-water-to-air intercooler. This new ProCharger system also has a much more attractive and "OEM" appearance than others for the GTO. Additionally, with the coolest charge air temperatures available, the HO Intercooled ProCharger system for the GTO produces not only the industry’s undisputed largest power gains, but also the best engine longevity.

Standard equipment includes an exclusive air-to-air intercooler system and a patented self-contained P-1SC-1 supercharger, with 3-year warranty available. This new product utilizes the same proven technology as the industry-leading Intercooled ProCharger systems for LS1 F-bodies and C5 Corvettes. In addition to the HO Intercooled system, a tuner kit and D-1SC serpentine race kit are also available. With modified LS1 motors, the D-1SC serpentine race kit is capable of supporting over 700 horsepower.

HO Intercooled System

7psi, 50-55% horsepower gain (5 psi pulley also available)
P-1SC-1 ProCharger, custom GTO specific air to air intercooler
100% complete with fuel injectors and handheld programmer
Dedicated 8 rib drive system with automatic belt tensioner

Tuner kit
Omits fuel injectors and programmer
Otherwise identical to the HO Intercooled System

D-1SC Serpentine Race Kit

D-1SC ProCharger intended for modified applications
8 rib drive system - requires the purchase of an aftermarket harmonic damper. ProCharger crank pulley is compatible with Fluiddamr part number 740102. This may also be compatible with other manufacturers
Otherwise the same as the Tuner kit

Magnuson



O.E.M. quality Mp112 5th Gen, "hybrid" roots style intercooled supercharger w/integral bypass valve
Intercooled application features a unique air to liquid heat exchanger that is integrated into the manifold, below the supercharger
Computer programmer - re-flashes factory ECU, spark and fuel control, transmission shift points, line pressures and torque converter strategies are optimized to manager increased torque, horsepower and mileage.
Two warranties - standard 3 year limited warranty or add an optional 36,000 mile 3 year powertrain warranty for $200.00
Does not void your warranty
100% complete with step-by-step instructions

This all-new intercooled supercharger system utilizes the Magna Charger MP112 supercharger with internal bypass valve. Torque and horsepower output is improved from 1500 rpm to 6500 rpm,

This kit is complete with all components necessary for installation. Included in the kit is the cast aluminum intake manifold and all necessary hardware to complete the entire installation. Other components in the system include new fuel injectors and extruded aluminum fuel rails, coolant circulation pump, intercooler core and heat exchanger. Factory push lock connectors are utilized in the fuel system for ease of installation.

Do you have any opinion as to which kit is more suited to the shade tree mechanic?

You can't go wrong with any of them. Each comes with detailed instructions for the install so anyone with basic mechanical ability should be able to bolt one of these on.

I'd say the MagnaCharger followed by the ATI in terms of a easiest, to easy scale respectively.

I'd really like to see is one car (preferbaly the same car) dyno sheet with each of these units at their best. This way we could settle which one is better. I'm really liking the ATI too, primarily because of it's performance, but if that performance comes in peaks, vs. the Maggie which may make less, but overall makes it smoother and more linear, I may sway back. See what I mean?

The other attraction to the ATI is that it's cheaper by a few hundred bucks. :)

The only section of the Maggie install that I'm afear'd of is drilling and doweling the pully. Just because I have no lift. That may become a moot point if I decide to cam the car. Then again.. who knows.. If the ATI can be installed from the top only then it is leading my list at this time.

Yea, my famous statement "6 of one, half dozen of the other" fits here.

The only thing I hate is having to drill into my oil pan and both these kits eliminate this.

Is it possible to get a copy of the instruction manuals so I can peruse it before deciding which system to buy?

I would hate to buy a system and then open the installation instructions and then collapse and pass out from the shock. It's not like we're changing the air filter here.....

Also which system is the friendliest to the hot desert climate?

I installed my maggie myself. There is no drilling and doweling the pulley involved. I did not have a lift. Everything was done sitting in my garage. You do have to remove the passenger front tire to get to the inner fender. The maggie kit is a quality product with great instructions. Step by step with color pictures. Takes between 8 and 10 hours to do. Installing the inner cooler heat exchanger & plumbing is the hardest part of the install.

The manual for the maggie I saw required drilling and doweling the crank pully. Maybe they changed it.

ATI offers their manuals for $25. That amount is then credited towards the price of the kit when you purchase it. I don't see the Vortech manual on their site yet.

For a pure clean look the ati and maggie look better, the vortech is just to much plumbing.

Although the maggie on mine required cutting the hood up.

Smooth, m/c is very smooth and very good for stealth. :secret:

I have the MPD Hood on my car & it is an automatic so it doesn't sit up as high. I only had to cut a small place about 1/2" wide X 3" long to clear the front edge of the throtle body.

The plumbing on the Vortech only LOOKS more intimidating from the topside. There's plenty of plumbing on an ATI that is not immediately visible in the photos. Remember you are routing 2 large diameter pipes to and from the area in front of the radiator. Whether that involves cutting, I don't know. With the Vortech, as in the Maggie, you only need to run 2 relatively small water lines to the front area. More ATI discussion HERE

Personaly the ATI is my favorite with the Magnacharger a close second and saddly the Vortech last. Though for racing, the Vortech would be the 'best' system since water/air cooling is the most efficient and you can easily run iced water in the cooling system for the aftercooler. The Procharger uses a front mount which is nice looking and probably works well on the street but unless you are moving, it isnt cooling anything. The Magnacharger would almost need iced water in the aftercooler considering the intake temps, but it does give good low end grunt. I still favor the look and sound of a centrifugal charger though, and with the low end power of the GTO, the ATI would help out the high end while not overimproving the low end too much.

actually there is not any real cutting except for the hood insulator, and the hood itself needs a couple of ball peen hammer wacks

What drilling, the only drilling I did was to mount the intercooler pump
Here's a link to the instruction http://www.magnacharger.com/pdf/manual09.pdf
