The most current models are the TD series turbine wheels.It roughly breaks down into TD generation of turbine wheel, 5H class of turbine wheel (specific size) , 16G compressor wheel, 6CM turbine housing.Turbine housingsBelow is a small chart translating the turbocharger information into more common A/R ratios that we are all used to seeingthese days as used with Garrett turbochargers.6 cm2 = 0.41 A/R7 cm2 = 0.49 A/R8 cm2 = 0.57 A/R9 cm2 = 0.65...

A wastegate is basically a device that bypasses some exhaust flow around the turbine section of a turbocharger to control maximum boost. A wastegate is usually controlled by a pressure actuator that is connected to manifold pressure. The wastegate is normally closed, held shut by a spring inside the actuator canister. When preset pressure limits are exceeded, the actuator progressively opens the wastegate, allowing exhaust flow to bypass the turbine, thus regulating manifold boost pressure. On the surface, it sounds like a simple premise, and in fact, a wastegate is a simple device. The problem comes from the pressure in...
