WEAPON-X.900 (Stage 6) [CTS V gen 3, LT4] WEAPON-X Motorsports

This CTS V package is the cream of the crop on the stock Eaton 1740 supercharger, taking the stage 5 package and adding ported heads and a ported supercharger with a 103mm throttle body to get the most free flowing air that little blower can handle!  Couple this with a stage 1-3 WEAPON-X custom cam and you have a stock octane monster.  We’ve done extensive testing on the LT4 wet sump platform to ensure this is the best and safest combo on pump gas!  The X900 package focuses on optimizing the most air into the engine with the camshaft, maximum overdrive of the supercharger, and exhausting the boosted air out.  This stage 6 package requires a tune, will get you approximately an extra 250 HP!  If you need help with a tune, we offer remote tuning services as well.

X900 PARTS DESCRIPTION:

• WEAPON-X SuperFlow-2 Carbon Intake:  Our wildly popular stage 2 intake picks up nearly 35 HP and the carbon fiber air bridge also dresses up the engine bay.  Includes powder coated heat shield kit and custom Green USA air filter.

• Nick Williams 103mm Throttle Body:  Nick Williams made 103mm throttle body for Gen 5 LT1 LT4 vehicles with modified inlet.  This is a billet 5 axis CNC milled aluminum throttle body with GM electronics and includes a 103mm blade.  

• IW Balancer and WEAPON-X Stage 6 Pulley:  This is the completely Interchangeable Crank Pulley Kit for the GM LT4 engine with pulley. The lower balancer is much lighter than the stock unit allowing for less rotational mass robbing your positive displacement blower of less HP per revolution. If you already have our kit installed on your car, you can buy rings separately for a quick and easy change to the boost level.

• WEAPON-X Camshaft Kit Stage 1-3, Johnson Lifters, ARP Head Studs, Gaskets, etc:  Looking to make more efficient positive displacement supercharged power and more aggressive lope?  Then step into one of our complete WEAPON-X cam kits for your next upgrade!  With the proper combination, the stage 3 camshaft has the +38% fuel lobe has put down nearly 800 wheel HP with the Eaton 1740 supercharger through the A10 trans! 

• WEAPON-X 370 CFM Ported LT4 Cylidner Heads:  Our ported LT4 heads offer 370cfm of free air flow, which is approximately a 25% increase in flow.  A more aggressive cam and pulley combo offers over 750+ WHP with the stock Eaton 1740 supercharger.

• WEAPON-X 103mm SuperFlow Ported Supercharger:  Our LT4 SuperFlow supercharger porting is proven to help free up the air flow, lower IAT2s, and gain 30-40HP across the RPM band!

• WEAPON-X Fuel Kit:  Supplies the necessary fueling

• 2″ Headers and off road X pipe:  Your choice between American Racing, Kooks, and Stainless Works.  All quality made in American systems!

• WEAPON-X Triple X Heat Exchangers:  Three carefully designed and thoroughly tested heat exchangers to cool the boosted LT4 engine.  Even stock boost CTS Vs can benefit grealty with 150% MORE fluid than the OEM system.  Calculated fin density, core thickness, internal tubing diameter, and core dimensions all go into making this system the hands down BEST on the market.  

• WEAPON-X 160* Thermostat:  Allow your engine to run cooler so you can push more timing when it’s needed.  This is a direct fit replacement.

• Brisk Silver Spark Plugs:  Brisk Silver Racing Spark Plugs are the best solution for high performance and racing engines. Silver Spark Plugs provide many unique and beneficial characteristics, Silver is taking sparkplug technology to a whole new level, here are many reasons why our Brisk Silver Racing SparkPlugs are beneficial for your engines performance. 

• Magnecor 85kV Spark Plug Wires:  Hi-Performance LT spark plug wires built to our standards, which mean they are built specifically for gen 5 LT engines and have the necessary heat protection for your long tube header installation. Our LT performance spark plug wire sets begin with a heat shielded Magnacor wire. Magnecor’s exclusive 2.5mm high capacity Metallic Inductance EMI Suppressed conductor consists of a stainless steel wire precisely wound at 200 turns per inch over a ferromagnetic core. 

• WEAPON-X Custom Valve Covers:  Powder coated any color including color matched to brake calipers which is popular.  Our billet valve covers are machined in-house and were designed from the OEM GM LT valve cover CAD file, and even reuse the OEM valve cover gaskets.  These include coil brackets to mount them above the valve covers or you can opt to relocate the coils to completely expose the valve covers.  These with the focus on improving the looks and the performance of your PCV system.  We have added ports in the baffling and enlarged the outlet ports for improved airflow.  This reduces the restriction seen by the crank case pressure which can lead to leaking front cam and rear main seals commonly found on higher HP LS and LT engines.  We have been private labeling these for the top LS and LT performance shops across the country and have gotten nothing but rave reviews!

• Elite E2X Catch Can:  Catch cans are imperative on parasitic engines that ingest the PCV oily air back through the motor.  The direct injection removes the fuel that ran through the cylinder head ports, which cleaned the back of the valves on previous LS engines; however, even they needed catch cans to filter that oily air and prevent oil from pooling inside the supercharger and caking and drying inside of the intercooler bricks.  

• WEAPON-X “X900” Badges:  Our classy badges are subtle and designed to compliment the car, while sporting your newfound power.  

• WEAPON-X “X900” Floor Mats:  Standard stitching color is silver with a red X; however, you can customize the colors upon ordering as well.  We know what you’re thinking, your CTS V has nice mats from the factory, but trust us, we have these private labeled by the best in the industry!  The ultra plush material is three times heavier than standard automotive carpeting.  The multi layer backing and urethane core provides extra cushioning helps insulates against heat and road noise and come standard with factory compatible anchoring devices.

• Amsoil Signature Series Synthetic Oil 5w-30 Oil Kit (10qts):  Develops a strong fluid film that keeps metal surfaces separated while its robust anti-wear additives further reduce wear in metal-to-metal contact regions for maximum engine life. The Sequence IVA Engine Test, which must be passed to meet the industry-standard API SN specification, simulates extended periods of stop-and-go driving. For 100 hours, the test engine cycles between 50 minutes of idling and 10 minutes of elevated rpm – conditions that encourage engine wear. The camshaft is then measured for wear in 84 locations and an average score is determined. We used Signature Series 0W-20, the lightest viscosity in the line, to further increase the severity of the test. AMSOIL Signature Series Synthetic Motor Oil provided 75 percent more engine protection against horsepower loss and wear than required by the industry standard, extending the life of vital components like pistons and cams.

• Amsoil Ea Oil Filter:  Features advanced full-synthetic media that traps and holds a greater amount of small, wear-causing contaminants compared to conventional filters. They provide extended service intervals for increased convenience, while helping reduce engine wear.

• Amsoil Coolant Kit (2 gal):  Independent tests reveal AMSOIL Antifreeze/Coolants greatly surpass standards for metallic corrosion and erosion, achieving nearly perfect scores in ASTM corrosion and erosion testing on cast aluminum cylinder heads, steel, copper, solder, brass and cast iron and aluminum water pumps.
