it’s good to see
@Shokeus has put a proper G50 gearbox into the RSS. I have been doing the same for the 964 Cup.
I have driven 964s and 993s on track more than any other cars, amounting to hundreds of laps at Goodwood and dozens at Castle Combe and Thruxton. The Cup car really does feel very Porsche-like, although I acknowledge the gap between a sim and real life which
@TheRealCeeBee and
@Cote Dazur have mentioned. It does need a bit of tweaking though.
I have put G50/3 ratios in the car, with a choice of two ratios for each gear, with the higher ratios being the equivalent of a G50/10 which I have seen occasionally fitted to a 964 Carrera cup. The G50/3 feels really good and true to life. All non-turbo 964s I have ever driven or seen have a 3.444 final ratio. It is possible to put other ratios in but I’ve never seen it.
I am trying to ‘BOP” the Carrera Cup to my own best lap times, sector times and corner entry and exit speeds in a C2. My best lap is around 1m35, as my insurance doesn’t cover track day damage! I’ve seen good driver friends manage 1m32.xx and I think a professional driver could do 1m30 without too much drama.
it’s worth reducing the CD by 10% or so and I’m working on the power.lut- real values don’t really work and actually most 964s measure quite a bit more power/torque than spec, even as measured on a chassis dyno. They also tend to rev freely up to 7000rpm, usually because the rev limit is the first thing that gets removed. It’s a bit of trial and error, but if people are interested I can post my drivetrain and power files in a few days.
