I can't comment too much on the various results but some are a little bit odd to say at least.

Regarding the RS Tuning 993 with 520 HP: one of the Rennteam team members is driving a 993 Turbo modded by RS Tuning with the 520 HP kit. This car was and is as fast as my 997 Turbo STOCK, so I doubt the published figures a little bit. I also met various tuned 993 Turbo with up to 540 HP claimed HP figures and only one was a bit faster than my stock Tiptronic 997 Turbo, so again I doubt the claimed figures. The 993 Turbo RS Tuning mentioned in the performance table is faster than the RUF 550 997 Turbo, this doesn't seem right, sorry.

Btw: the 997 Turbo RUF 550 HP testing has been done with GPS testing equipment, the result is pretty accurate and the 200-300 kph acceleration time has been clocked at precisely TRUE 200 kph and 300 kph, NOT speedo figures!


RC, you are of course correct the hp number in Alex's table is incorrect however most of the other numbers are also. My GPS tested numbers are:
0-100 3.8s
0-200 11.1s
0-300 28.9s
100-200 6.6s (3rd gear start)
100-300 25.1s (2nd gear start)
200-300 17.8s
Max PS 577
DIN weight 1455kg
4WD
GT2 flares, CdA 0.72 (stock 993tt= 0.66)

So you see the car is 50kg lighter than stock and has bespoke 2006 build engine with ~570hp from 5000rpm to 7000rpm on the RS engine dyno. With stock bodywork the acceleration over 250kph would be quite a lot better.

I am also keen to get RS38s slope program to run over and correct for the slope during my 0-300kph run, it is over 4m up to 280kph.......

There are so many factors to take into account for all the figures in the table which effect the numbers:
Slope
Car running weight ie passengers/fuel load
Aerodynamics ie stock or add on wings increasing CdA
Size of wheels
Gearing (particularly important when comparing in between speeds ie # of gearchanges)
Road surface
Climate on day of the run
Wind on day of run
Speed of gear shifts

A 530hp RS Tuning 993tt body with the correct gearing and special aerodynamics can easily by near the top of the chart for 0-300, the specialy geared 5 speed one they built with sloped windscreen and narrower aero body did 0-300 in ~25s back in '97 ! In fact that very car is for sale now for 55K Euro
