You are right, Bobby was running the big carb and the aftermarket silencer. Both of which give more power as you saw on top end. AJ was running a true ICC package, but his engine is what they call a factory tuned motor so in a sense, it was stock. It appears to me that CRS does a little better job of making their engines work than some of the others. Ryan Bailey’s motor was stock through the qualifying and pre-final but he put a big carb on for the main.
If you look at the PMT times, the full on ICC has been consistantly faster than a full on moto by about .3 to .5 seconds but you have to remember that SKUSA allowed the aftermarket silencer. I believe that an ICC in full CIK spec will be very close to a SP/S1 quality moto package. The head restricted and spec ignition moto will be somewhat less and the ICC will then have the clear advantage.
