Because of all the Engine Dyno tests that FRPP has done on these powerplants. They feel these Spec items for each motors will produce pretty close the same HP. Some might have less, but have more torque to make it up. But, if you add HP+Torque they are all real close.
If we feel that the Dyno numbers are off....we'll make adjustments. I don't expect to make any major adjustments during the 2006.... but for the 2007 we'll take all the data, and look at all the Spec rules again.
It's best we don't make a lot of changes the first couple of years, because we could have been right with the first set of rules. If we do make a lot of early changes, we could be just chasing our own tails.
