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.

The 80mm inlet Flow Advancement Port™ version can be used with our Intake Air Pipe which is located in the Related Products section at the bottom of the page. The intake is undercover black and designed to replace the stock intake air pipe perfectly allowing the use of the recirculated BOV and the valve cover crankcase vent as in the OEM application. The 80mm Flow Advancement Port™ cover can also be used with standard 3" air intake pipes by utilizing a straight 3" coupler also located in the Related Products section at the bottom of this page.

The FP Red turbocharger for the EVOIX is the only stock format turbo capable of delivering 550+whp with some examples recording over 600whp. Typical installations of this turbo result in mid to upper 400's on pump gas and mid to upper 500's on race gas depending on ambient temperature and related mods to the car in question. Typical boost threshold is about 3700RPM with some cars spooling up slower or faster depending on camshaft selection and other variables. The turbocharger should be operated at 22-24psi on pump gas and about 30-35psi spike dropping to 25-27psi by redline in race gas applications.

Using the turbocharger for higher boost race gas applications requires the use of the full flow oil feed line to supply adequate oil pressure to the thrust bearing of the turbocharger. See the related items link at the bottom of the page for the recommended oil supply solution for high boost (25psi or more) applications.
