Greatly Improves Throttle Response. Increased Horsepower. Lower EGTs. Easy Installation - no modifications needed. Increased Boost. While capable of high boost numbers with supporting mods these wheels are safe for stock turbo applications!

Application: 2004.5-2005 Cummins

Important Tip:It is a left hand thread (reverse thread), meaning you turn the nut to the right to loosen. The Wicked Wheel is balanced at the Factory. Turbo balancing after installation is not necessary.

Note From Bob Riley: Our goal with this project was to create a more efficient turbocharger. When we talk about a turbo's maximum recommended boost levels, we base that on the rpms the turbo needs to turn in order to create said boost. When you increase boost without increasing rpms or drive pressure, the load on the turbocharger is the same for the elevated boost as is was for the original lower boost number. The best part is when you run at lower pressures, like you would in daily driving conditions, the drive pressure/ boost pressure ratios are always lower, which should in turn result in longer turbo life, not less. ~ Bob Riley
