Doesn't quite work that way on the drum. The larger tire eats up any extra hp the extra cc's give you. Next to no real gain between them stock vs stock2002 1130 cc Race Tuner canned map, screamin Eagle exhaust, with K & N air filter.
Add 100 cc and you have 120hp, sounds about right.
It's also standard smoothing. These numbers are always higher. The only ones that are accurate are SAE smoothed. Now don't get me wrong, the numbers are good but unless they are SAE smoothed it's not accurate when comparing one dyno to another. Apples and oranges . SAE smoothed is the true standard for measuring and it is almost always a lower number.REALLY happy dyno!!!!:angeldev:
