Well after my old M5 (beastpower's car), I now sold my TT and Cayenne and got a replacement (RS6). I was looking at the new E55 but no AWD to go skiing. The new M5 not for me as I am not in love with the styling.
2003 Daytona Gray with Black Interior, CF Trim, Miltek Full Exhaust/Flow cats, GIAC software with 3 modes (91 Stock, 91 race and 100 race), RS6+ Pedals, Euro Front and Rear lights, Sportec 19's with 285 rubbers, Clear Armor protection, Valentine One (needs to be hardwired), Sirius, Diverter Valves.
Not dynoed yet but should be around 540+HP/550+TQ on 100 gas.
one thing you guys are forgetting is they are turbo charged.. BOOST is your friend... some companys are picking up 10hp per pound on safe settings. some more.. take my toyota for example, stock 296 to the wheels, on 13 psi. I did a 3" exhaust, 3" down pipe, 18 psi 345 to ground 22 psi 400 wheel hp and 24 psi 435 wheel hp..( this was out of the range of turbo) Trubos are like drugs... once you get high you have to have more...
Is there a link to that company that makes the parts for the Audi RS6? if so would you mind posting it so i can tell david about it.
