Thanks. It was years ago when John?!?? told me the increase in rate and he stressed it was a best guess. I was surprised at the increase he quoted from my understanding I have of biomechanics (and bone function) the diameter shouldn't make much difference to rates.
I didn't notice a huge change to the car when I upgraded the front and read bars over stock but then again (as it turns out) the bars were much closer to factory RS4S bars. This was so many years ago my memory is shaky.
From memory the front sway bar rate is about 40% higher going from hollow to solid of the same diameter (after talking to the guys at Whiteline all those years ago...happy to be corrected if this is wrong), so it is a bit of an upgrade. The rear bar on the RS4S is a hollow 24mm bar and is identical to R33 GTR bars.
They were different. Grosjean had cars either side of him and therefore more decisions to make regarding the location of cars on all sides. How you determined it was deliberate beats me, it was an error of judgement and he was penalised for it. The other was a case of driving into the back of another car. Once is unfortunate but twice in a season?? 10 places is slap on the wrist.
You think harsh enough, I think not consistent.
Grosjean gets a weeks rest, Red Baron gets a slap on the wrist. Consistently inconsistent.
"Mercedes’ Michael Schumacher has been punished by the Singapore stewards for his collision with Toro Rosso’s Jean-Eric Vergne during Sunday's Marina Bay race. Schumacher receives a 10-place grid penalty for the next round in Japan.
Schumacher and Vergne both retired immediately after the Mercedes driver slammed into the back of the Frenchman’s STR7 on the race’s restart following the first safety-car period. "
Leave the stock BOV. There is no performance to be gained buying a new one.
If you want to get the most out of the turbo upgrade buy the injectors and the Z32 AFM. You will pay for tuning twice when you eventually upgrade them.
If you are sticking with stock injectors and afm just run the stock turbo to 12psi with a good tune and it will do the job perfectly well and make around 200rwkw +/- 10kw.
Turbo upgrades always means more money. A hiflow is a pretty sensible way to go to keep costs down but it is always going to cost more than you think.
Hiflow turbo, injectors, AFM, Nistune + tune. (assuming FMIC and 3" exhaust already done).
