Features & Product Details

RallySport Direct proudly carries a great selection of performance intakes, intercoolers, and accessories brought to you by Process West. 

Here, you are looking at the Process West Street Version Intake Manifold. This intake manifold is simply a work of art in the engine bay made using full billet aluminum construction with billet bell mouth ended runners. This intake manifold is ideal for vehicles requiring more power in the upper rev range in big horsepower builds. 

 

DETAILS:

  • Street version
  • Full billet aluminum plenum 
  • Biller bell mouth ended runners
  • CNC mandrel bent tube components
  • Anodized black finish
  • The manifold is the result of years of research and testing, multiple prototypes and ground-up redesign of the original  groundbreaking  "Corsa Veloce" product range
  • High-end TIG welding assembly makes them suitable for up to 100psi boosted applications
  • The plenum volume and runner length combination  has  been selected for aggressive low and mid-range torque while opening up power higher in the rev range
  • The plenum volume is large enough for serious gains but is still compatible with factory AC
  • The Street version is suitable for any level of performance modification as they have conducted tests on completely stock engine/turbo/fuel system setups with approximately 9% gains in torque and power level, with the same percentage gain on highly modified setups running E85
  • For a fully streetable but aggressive setup, while retaining the comfort of AC, the Street version manifold is the solution
  • 9% gains in both horsepower and torque on a stock engine

    5out of 5stars

    This manifold in absolutely amazing! Super strong, very well built and looks unreal Under the hood! Performance wise... Super smooth. The car runs so much better, more responsive, just all around much better than stock. The numbers I put down with the manifold and other mods were 430/367. If you’re looking for a worthy performance upgrade, as well something that will make the engine bay look good, here you go!

    Simply Amazing  2 years ago
    5out of 5stars

    Used this manifold for my build. Along with a stage 2.5 block. CNC ported heads. Cams. EL header. Blouch DOM 3.0XTR All work was performed by EFi Logics in Bethel CT. Tuned by Calvin Dotson on a Mustang dyno in house at EFi Logics. Set up made 469awhp and 403awtq. I couldn’t be happier. This manifold is simply amazing. It’s not just a pretty face... she puts it down. Worth every penny.

    QUESTIONS & ANSWERS

    • Q: Process West FMIC?  leenypost9 months ago

      Would I have to modify the Process West FMIC tubing to fit this Manifold or do they supply something that would make it work between both of their parts?
      • 0 of 0 people found the following answer helpful

        A:  You will need to modify the intercooler pipe at the throttle body. The throttle position on the Process West intake manifold is lower and closer to the firewall compared to the stock position.
