FP has just released a new ant-surge compressor cover for their Evo Red turbo.
NEW to the FP RED™ for the Evolution IX Line up is our own custom 80mm Flow Advancement Port™ compressor cover. You can now choose the new FP 80mm Flow Advancement Port™cover or stick with the standard 63mm Stock Appearing compressor cover as shown above. The larger inlet configuration helps reduce huffing and surging sounds that are often reported with these larger stock format hybrids when lugging the engine at low RPM and high boost pressure but perhaps even more useful is the way it helps feed the splitter blades of the compressor wheel resulting in increased flow. This larger inlet also increases the volume of the intake air pipe and reduces vacuum at the inlet of the turbo. Additionally the volute of the cover is now exactly tailored to the HTA wheel aero for the best performance possible.
