Supercharger Boost Upgrade: Available in Stage 2 Power Package

Application: 2006-2008 STS-V

The final step in our Stage 2 Power Package is to increase the boost output of the factory supercharger greatly increasing horsepower and torque levels through the entire power band. Because we spin the supercharger close to its peak rpm, this package also includes the intercooler and methanol injection to keep induction temperatures down.

Intercooler Upgrade – MSRP $495.00

Application: 2006-2008 STS-V

One of the biggest horsepower killers on forced induction vehicles is heat and the 4.4L supercharged Northstar often suffers from bad heat soak. When a supercharger or turbocharger compresses air, it also generates additional heat. Keep your cool and help lower your intake air temperatures with our intercooler upgrade. This unit dissipates heat more efficiently than the stock unit and will help to reduce inlet temperatures. In addition to the characteristics of the replacement unit we also added a 1600CFM push fan to further help increase cooling efficiency. Every intercooler upgrade comes with a bottle of Purple Ice additive to greater increase cooling efficiency. This upgrade will result in much more consistent power when the vehicle is subjected to spirited driving conditions.

Intercooler Reservoir – MSRP $500.00

Application: 2006-2008 STS-V

The entire factory STS-V intercooler cooling system holds 2.6 quarts of fluid. By adding the D3 Intercooler Reservoir you will effectively increase the total fluid capacity to 5.6 quarts. This will help stave off heat soak and reduce your average fluid temperature. It will also help provide you with much more consistent performance in hot weather. By adding more fluid to the system, the compressed air going through the intercooler will only be able to transfer its heat to a smaller percentage of the fluid cooling the air charge. This item comes in a wrinkle black finish with mounting brackets for easy installation. This product installs using factory hardware without drilling or cutting. The low gloss black finish keeps this modification very low key when mounted behind the wire mesh grill.

Methanol Injection System – MSRP $550.00

Application: 2006-2008 STS-V

Boost Juice: $29.95 case of 4 gallons

Another method we use to drop inlet air temperature is through methanol injection. By reducing the inlet air temperature, vehicles are less likely to suffer from detonation or pre-ignition. Reducing inlet temperatures allows for a denser, more power charge in each cylinder resulting in greater horsepower and torque gains and longer engine life. This is especially helpful in high output or over boosted applications.

Supercharger Lid Upgrade – MSRP $995.00

Application: 2006-2008 STS-V

D3 is always looking for ways to increase the potential of every vehicle. We have developed new modifications for the upper end of the engine.
