CA18 manifold - top mount - single scroll - external WG

This CA18 manifold, in top mount design, single scroll flange and external wastegate, is ideal for a turbo setup with Garrett GT / GTX28 - 30 or G25 / G30 charger.

Our CA18 manifolds are hand-made in-house from high-strength 1.4541 V4A . The runners have a wall thickness of 2.6 mm .

The pulse charging principle achieves a significant increase in turbine efficiency compared to conventional turbocharging, as the turbo is not driven by the exhaust pressure, but by individual exhaust pulses that are fed to the charger inlet. The result is improved spool-up , significantly higher charger efficiency , earlier response , maximum peak power and a wider torque band . In addition, exhaust back pressure is reduced, which leads to a lower exhaust temperature , higher scavenging effect and better fresh gas filling .

Our collectors are also handmade. We attach great importance to the angle of attack being as sharp as possible in order to ensure optimal flow to the exhaust housing and selective activation by the exhaust gas pulses.

In addition, we always try to achieve the best possible pipe length compensation in terms of installation space and charger position in order to guarantee the maximum efficiency of the manifold.

Our flanges are made of a steel alloy that has reduced thermal expansion and is also less susceptible to distortion.

Optionally with T25 or T3 flange. For applications with V-band flange, please contact us regarding a custom-made product.
