corradophil 3 Posted October 31, 2012 (edited) Mk3 Golf GTI 2.0 16v ABF modified upper intake manifold. Below are graphs comparing the standard and short runner intake on a standard ABF engine. Please note in both cases the engine fuelling and ignition maps were optimised to suit the manifolds fitted. The Blue line shows the short runner torque and power outputs, and the green line shows the standard length runner torque and power outputs. Torque Plot (Vertical axis is torque measured in Ibft) On average the torque increased by around by 7Ibft between 2250rpm and 5500rpm resulting in a stronger feeling engine. Power Plot (Vertical axis is power measured in bhp) The blue short runner plot shows a power increase at all engine speeds. I had the manifold shortened by a local fabricator for use as part of a conversion on my Corrado 2.0 16v to stand alone engine management, but the project took a different direction, so it is no longer required. For further background information, please click this link http://www.clubgti.com/showthread.ph...ment-(results). The upper manifold section has short runners, but the plenum volume is standard.
