6Boost Turbo Manifolds

It’s safe to say that the 6Boost manifold is one of the best performing turbo manifolds in the world. For more than 10 years, 6Boost have built a global reputation for being one of the strongest and best flowing manifolds on the market. Each 6Boost manifold is hand crafted to the highest of standards and built to last a lifetime. These manifolds are heavily sand blasted inside and out to improve the surface finish and ensure there is no scale or contaminants that may damage your turbo.

Design & Construction

6Boost manifolds are specifically designed for to suit your application and are built around their unique ‘merge collector’ design. This type of collector technology has been used in the highest forms or motorsport for years, but never applied commercially to turbo manifolds anywhere in the world, until now. All pipes enter at the exact same angle, and merge together at a point in the middle, pointing straight into the turbine. No pipes enter across each other, so airflow is not disrupted. The design of this merge collector mean that all gases are directed at the turbine entry with absolute maximum force, converting into quicker spool and better performance gains. By using this merge collector design, we have seen spool times reduced up to 400rpm, power gains of up to 15% and peak power is held from anything up to 600rpm longer. These figures have been proven time and time again in back to back dyno testing.

6Boost manifolds are finished to the highest standards, constructed from thick wall mandrel bent steam pipe and are designed and built to be one of the highest quality manifolds available. They are completely tig welded with laser cut 16mm head plates and come with an optional external wastegate outlet in a size of your choice. These manifolds come coated in a high temperature exhaust enamel that has proven to withstand excessive heat, however you also have the highly recommended option of HPC Ceramic Coating the manifold which significantly reduces engine bay temperatures under bonnet in order to improve engine performance and longevity.

With your 6Boost manifold, you will receive a lifetime warranty against cracking and manufacturing defects. All manifolds come complete with new head and manifold studs, nuts as well as a high quality manifold to turbo gasket. Due to high demand and Covid-19, lead time is approximately 8 weeks.

Wastegate flange size:
38mm, 45mm, 50mm, 60mm, no flange.

*Please note* single wastegate applications require a minimum of 45mm external wastegate – 50mm is highly recommended. Wastegate sizes such as 38mm or 40mm will not control boost on a merge collector style manifold.
