Does anyone know which one is the Ruf 490R?

Ruf is a one off low drag bodywork ~1360kg with special engine claimed 568PS motor running on 102 RON race fuel

RS Tuning was running in limp mode courtesy of disconnected IAT temp sensor so about 520PS, 1470kg and high drag GT2 bodywork on 99 RON fuel

Ruf was quicker and impressive although on the drag out of the bottom corner the RS was in 3rd and the Ruf in 2nd hence the acceleration differential- the owner has just taken delivery of his new CTR 3

Toby,

Thank you for the information.

I am looking for a similar real time road test with a Ruf 490R and RS Tuning 520 PS, any ideas?

None exist. Ruf was pretty coy in those days about letting the press back to back his cars against RS Tuning, don't forget RS sandbagged with their 533PS 993 lookalike which did 0-300 in 26s and 221mph so Ruf had nothing to gain since he was still living off the Yellowbird CTR....

I would say the 490 TurboR compared to an RS 520 car would have been as quick to 200kph at around the 12s mark then it would lose out as the speed rises above 200kph and the hp starts to show. Remember Ruf did/does clever things with gearing, weight and aerodynamics (see above) which make a difference - as I found out
The turboR 490 will by definition be more responsive because of its K16 based turno vs K24 for the RS.

In the big 60-130 thread Bill S (Ruf 490) recorded a 9.1 and MOD500 (RS Tuning 520-ish) an 8.7.

Not surpising that MOD500's is faster than the Ruf 490R....as I understand its' build spec. is above the RS Tuning 520.
