I'm sold on the 178 + 68mm Code3. Just got to get a new belt and the belt wrap kit back on and I expect to pick up a little more than yesterday. I am truly impressed by the people running just the Code3 pulley. They seem to be putting down some nice numbers. The 185 should be the best of the crank pulleys theoretically if the intake temps are kept under control, but maybe no one else besides Riot and 240 has really track tested them. The only way to truly compare these different combo's is to track test them on the same car, the same day and log all the variables that are possible.
