Adrian has finished fabricating the short-runner intake manifold, so we're really making good progress now. The short-runner intake (SRI) is necessary as a replacement for the factory manifold because the OE manifold's plastic construction would not allow for the levels of boost we plan to run. And while the long runners and varying geometry of the stock manifold make for a nice horsepower-torque compromise in normally aspirated mode, with positive manifold pressure they will only serve to limit flow. With that in mind we have constructed a version of Adrian's Mk4 R32 SRI that incorporates a large plenum and shorter runners.
