should help the FI guys from running out of fuel with an over drive crank pulley, should help the NA crowd by increasing MPG from the higher pressure DI shots, and more importantly should be a far lower cost option than swapping out the HPFP to a higher flow unit and does not need any further R&D, well, from comp cams maybe
similar to this: http://shop.zzperformance.com/store/...ge-1-Cams.aspx
under the "additional information" tab and this: http://www.cobaltss.net/forums/2-0l-...e-hpfp-284190/
same priciple but on the SIDI V6 instead of the ecotec 4 cylinder platform |
Nice first post
