What can you benefit from Forged Billet 

Compressor Wheel?

Stronger Wheel:
By using forged billet aluminum to make the wheel, there is no chance of minute air bubbles being in the mental. So, you don't need to worry about porosity issues. That means billet compressor wheel is much strong than cast compressor wheel.

Better Blades Design:
By using forged billet aluminum and machined on a 5-Axis mill, the billet compressor wheel can be designed much more aggressive, the nose and hub can be designed significantly smaller to allow for a greater blade diameter. And the blades can be made much more complicated to increase blade surface area, which can flow more air into the engine.

Lower Engine Intake Air Temperature:
By using forged billet aluminum, the wheel can be machined much thinner. This allows the wheel to have a greater efficiency range, because their is less blade thickness to contact the air and heat it up. It also means that with less blade thickness and lower hub area that there is a greater area in-between the blades to squeeze more air and build boost presure. The more efficient a wheel is the lower the intake temps, and everyone knows the cooler the air going into the engine the more horsepower you can make!

What can you benefit from our dual ball bearing 

turbocharger?

Reduced Turbo Lag:
Dual Ball Bearing turbochargers can spool up about 15% faster than traditional journal bearings, so it will signifcant reduce the turbo lag when the throttle is suddenly opened. This produces an improved response that can be converted to quicker 0-60 mph speed. In fact, when you drive with a dual ball bearing turbocharged engine, it will more like driving a big, normally aspirated engine.

Reduced Oil Flow:
The Dual Ball Bearing design reduces the required amount of oil required to provide adequate lubrication. This lower oil volume reduces the chance for seal leakage. Also, the dual ball bearing is more tolerant of marginal lube conditions, and diminishes the possibility of turbocharger failure on engine shut down.

Improved Rotordynamics and Durability:
The Dual Ball Bearing cartridge gives better damping and control over shaft motion, allowing enhanced reliability for both everyday and extreme driving conditions. In addition, the opposed angular contact bearing cartridge eliminates the need for the thrust bearing commonly a weak link in the turbo bearing system.
