Interested to flesh out whether the detuned Euro 5 LS3 fitted to the VFII SS has the same measured (dyno) output as VE (HSV, CSV, VXR, GXP) LS3 at 317 and 325, or even the HSV SV340. The final factor of boot badge divided by 1.27 holds true for all variants except the Euro 5, where the best calibrated evidence shows ~220 rwkw which, multiplied by 1.27 is not 304, as claimed in the sales brochures. The output correlates to that of the VEII, which has a 0-100 of 5.4s versus 5.3s of VFII which is fitted with shorter diff gears. So, let's see if we can reach a consensus. No opinions please, only post dyno results which are verifiable. Third gear pulls and charts not showing derived RPM method are of course good for nothing.
