What makes the compressor wheel of a turbocharger turn?

As the exhaust gases exit the engine they spin the turbine wheel within the turbocharger. As the turbine spins, so does the compressor, forcing intake air into the inlet manifold at a higher pressure, and therefore creating boost.

What does the turbine wheel do?

The turbocharger turbine, which consists of a turbine wheel and a turbine housing, converts the engine exhaust gas into mechanical energy to drive the compressor. The gas, which is restricted by the turbine’s flow cross-sectional area, results in a pressure and temperature drop between the inlet and outlet.

What does a bigger compressor wheel do?

A larger compressor wheel will allow the turbo to flow more air. More airflow, as we know, equals more power (with the correct modifications and mapping)! Our hybrid turbochargers usually feature the fitment of larger compressor wheels than standard.

What spins the compressor in a turbocharger?

A turbocharger consists of a compressor wheel and exhaust gas turbine wheel coupled together by a solid shaft and that is used to boost the intake air pressure of an internal combustion engine. The exhaust gas turbine extracts energy from the exhaust gas and uses it to drive the compressor and overcome friction.

At what speed does turbo kick in?

150,000 revolutions per minute
The turbine in the turbocharger spins at speeds of up to 150,000 revolutions per minute, which is 30 times faster than most car engines can go. The turbine’s temperatures are very high since it is hooked up to the exhaust.

Does a turbocharger compressor air?

In simple terms, a turbocharger comprises a turbine and a compressor connected by a common shaft supported on a bearing system. The turbocharger converts waste energy from an engine’s exhaust gases into compressed air, which it pushes into the engine.

What is the disadvantage of turbocharger?

A turbocharger used without an intercooler can create extremely high heat in the engine compartment of the vehicle. This additional heat can lead to overheating breakdowns, melting of critical plastic engine components and fires. Using an intercooler mitigates this problem, but is an expensive addition to the system.

How do I know my turbo size?

A larger A/R will take longer to spool (boost lag) but will be able to flow more air. In short, a small A/R has high response with limited power; a big A/R will result in slow response but with bigger power.

How does a compressor wheel work?

As the compressor wheel spins, air is drawn in and is compressed as the blades spin at a high velocity. The housing is designed to convert the high velocity, low pressure air stream, into a high pressure low velocity air stream, through a process called diffusion.

At what RPM do turbos kick in?

While your car’s engine revs, at cruise, at around 2,000 rpm, a turbo’s turbine can reach rotational speeds of more than 280,000 rpm.

How is a turbocharger compressor wheel is made?

The video presents turbocharger compressor wheel manufacturing process at KTS Turbo Billet X factory. For compressor wheel balancing KTS selects balancing machines from CIMAT.

Why do I need 11 blade compressor wheel?

You will see taller 11 blade compressor wheels in the GTX series compressor wheels which are created by garret. The higher the blade count also helps with spool time, because it captures more air at lower rpm of the turbo.

Can a larger wheel be used for a turbo upgrade?

The fitment of a larger compressor wheel can be a very effective upgrade and it’s all machined in-house meaning we can get your upgraded turbo back to you faster. A Re-Profiled Compressor Cover allows the fitment of a larger compressor wheel which is an essential part of the hybrid process.

Why is the turbine wheel bigger than the compressor wheel?

Firstly, the larger turbine wheel can drive the compressor wheel harder resulting in more airflow, and with more airflow equals more power potential. Secondly, the larger wheel reduces backpressure within both the turbine housing and manifold in much the same way as a Cutback would when applied.
