2x +400 bhp and some other - 08/06/2007 16:51
Hi,
Yesterday we had 5 Coupes in RR here in Finland.
Here are the results from top to bottom :
1. Coupe with TO4, 413 bhp / 489 Nm (361 lb-ft).
2. Mine with GT3071R, 408 bhp / 479 Nm (353 lb-ft).
3. Coupe with GT28RS, 333 bhp / 400 Nm (295 lb-ft).
4. Coupe with GT28R, 319 bhp / 470 Nm (347 lb-ft).
5. Coupe 16vt with chip, 255 bhp / 410 Nm (302 lb-ft).
And yes , all the cars with std internals. First and mine have C&B cams, otherwise nothing else done to the engines.
This time I really didn't took all out of the turbo, just becauseof the std internals. My goal was +400 bhp, I did three runs: 399 bhp, 408 bhp and 408 bhp. After first run I add some duty cycle % more to go above 400 bhp .
Fuelling was more or less overfuelling, EGT under 900 degC in all my runs.
