I'm gradually getting my GTI VR6 going, and trying to hit the right R&P the first time. My number crunching tells me a 3.94 without accounting for part of the aero. A fudge to 4.23 to account for the missing aero seems about right, but I wouldn't want to run out of gear at WGI. Anyone have advice? Bill (Bildon) in the Corrado? Mine's going to be a GTI, so it might have worse aero that I'll have to account for. Anyone else run a VR6 yet at WGI, Lime Rock or NHIS? TIA
