Kinugawa Turbo Systems Line-up Code Explanation of TD Series

Posted by Service Kinugawa on

Kinugawa Turbo Systems these days carry the TD prefix followed by a number. the number generally designates the class of turbo and turbine wheel size. 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...

Big Head vs. Normal Head Actuators

Posted by Service Kinugawa on

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...

BOV vs BCV: What’s The Real Difference?

Posted by Service Kinugawa on

The purpose of a BOV/BCV is the allow that excess pressure to escape. It works through a vacuum port on the BOV/BCV which enables it to measure relative manifold pressure. When the throttle body closes, a vacuum inside the manifold will be created. If the relative manifold pressure drops below atmospheric pressure, the valve opens and allows air through it.
