Is external wastegate better than internal?

Is external wastegate better than internal?

Internal turbos are great for OEM applications, but external wastegates allow for more flexibility with the overall design, and can result in a more productive turbocharger as they can route the exhaust gases further away from the turbo housing.

Is an external wastegate necessary?

If you’re able to tune your turbo to your desired boost level with no issues, and you’re able to effectively control boost with no signs of boost-creep, then you most likely don’t need an external gate.

What does a screamer pipe do?

A screamer pipe is a type of exhaust configuration fitted to some automotive turbocharged petrol engines with an external wastegate set-up, which vents the waste exhaust to the atmosphere through a separate un-muffled pipe, rather than back into the main exhaust track. This exhaust setup is known for its loud noise.

What are turbo housing made of?

Turbine housings are predominantly made by casting processes but assembly by welding together stamped metal pieces is also possible. Some casting materials used for this application include: ductile iron, ferritic cast steel, austenitic alloys and aluminum.

What is turbo exhaust made of?

The turbine housing has a spiral design and it is typically made of steel or cast iron. Its main function is to collect the exhaust gases from the engine, before directing them into the turbine wheel.

What size wastegate do I need?

The more exhaust gas the wastegate vents, the slower the turbine wheel will spin. For a turbocharged car that sees primarily street use, most people think the smaller 38mm wastegate would work best, and although it is not a bad choice, ultimately the 44mm would work better for most street applications.

Are turbo housings interchangeable?

So yes, the turbine housings will interchange.

What does compressor housing do for a turbo?

The compressor housing is where clean air is gathered and compressed before being forced into the engine – it houses the compressor wheel.

  • What size external wastegate size to use?

    The Size of the External Wastegate That you Should Use Depends on 2 Major Factor Which are: What Size Engine Do you Have (2.0 liter 4 cylinder, 2.5 liter 6 cylinder, v8 4.4liter etc) In Most Cases the 38mm Wastegate Is Sufficient to Control Boost for 4 cylinder and 6 cylinder engines, if you are running a 60mm turbo or smaller such as GT35r.

    What is the advantage of an external waste gate?


  • Pneumatic
  • Electric
  • Hydraulic
  • How to adjust the external wastegate on a turbo?

    Offer a superior flow path.

  • Wastegates are high-temperature resistant.
  • Engineered to outperform and outlast the competition.
