i have a 05 c230k and i jus so happend to pull up next to a g35 coupe which guessin by the way it was changing gears was automatic.. anyway we started from second gear.. i kept up with it until like 4th gear then it pulled just a little bit from me.. so im starting to wonder if 189 horses and 275 for the g35 is a big difference? i thought it would jus pull right from second gear but i actually hung with it with this engine.. its really not bad man i mean even adding a chip to beef it up would make it nice.. i even kept up with an s2000 and s2000's beat g35;s in a race i think?.. because i saw an s2k and a g35 race but who knows wut the outcome could of been if they went top speed.. but yea thats the story
