With more than 10 years’ efforts putting in New Complete turbocharger manufacture and turbo remanufacturing ,powertec has found that the OEM design is not always the best choice either in design or performance. In order to supply the better products, has made some modifications from OEM design. Most of the Upgrades have been approved and accepted by more and more customers.
Turbine Wheel Cutback Upgrades
Turbine Wheel Cutback is a machining process which enables the engine to increase power output by reducing back pressure. Turbine wheel with cutback can also reduce some of the noise and whistling in turbocharger.
Ball Bearing Upgrades
A Ball Bearing Conversion improves response of the turbocharger and makes it more reliable. This is done by replacing the traditional thrust bearing and journal bearing assembly with a dual ball bearing cartridge assembly. The dual ball bearing cartridge has significantly less frictional drag, which will improve the response and power for output.
Twin Seal Conversion Upgrades
The process involves machining of the piston ring area on the shaft and the seal bore area of the bearing housing to allow a second piston ring seal to be fitted. It reduces oil leakage on turbocharger with low back pressure exhaust systems or higher than usual crankcase pressure.
A high-tech enterprise focused on the research, development, production, and sales of turbochargers.
