Thanks guys
Just some notes;
I did about 25 runs up 300kph with the maximum before breaking zone being 313kph at which point I am just over 7000rpm anyway so no more to come.
The run I have posted is the fastest with them getting faster as the car got lighter as the fuel depleted.
I will post a video of the standing start, I only did two because like most of us, I don't enjoy the stress that it puts on the car, but yes it was a crappy start first gear a mash of wheelspin but straight into second which gives full grip and we are off
The airstrip is a horrible surface, we are attempting some calculations to determine how much acceleration it "costs" compared to smooth asphault, and of course it is up hill - for reference my 100-200kph on a flat smooth surface is around 6.6s and on this run (which the car is probably 40kg lighter) takes 7s.
Alex, re the 0-200kph, also remember the 993tt takes 3 gearchanges to get there unlike the 996/997tts
I was very pleased that my new spoiler set up proved aerodynamically pretty good although we are calculating the drag coefficient of my GT2 arched 993tt based on some "coastdown" runs from 275kph which I did - it is looking like around Cd0.36 TBC....
My pal's stock bodied 993tt with RS Tuning 533PS engine weighing 1630kg was posting 0-300 equivalents of around 36 seconds which is about the same as that 997GT2 which is making me interested that it is CdA which we should be looking at since the 993tt has Cd 0.34 CdA 0.656 and the 997GT2 has Cd 0.32 CdA 0.66 - looks like the CdA is the real determinant of high speed acceleration
