The first combo, it has consistently provided faster results if you look on drag times!

However! The 181 or 185 pulley with an inMotion or Eurocharged tune and some extensive cooling mods (the massive crank pulleys create massive heat) then the car will be a beast no doubt.

On a side note the FASTEST 3 combo is the inmotion tune, ASP 178 crank pulley, nw cai, I'm not sure why as the 178 is pretty much the same as the code 3 but for some reason all the guys running that setup are abit quicker.
