The KB blower looks good and efficient but I believe you will get more power out of a bigger blower. I am not taking anything away from KB but it looks like they were the ones who did the test in the article and not a 3rd party. I think the tests will always be skewed towards a manufacturers product that is doing the test. I can't remember the comparison between the Hennessey 650 car and the 725 Super Snake - didn't they dyno close to the same?? It will be interesting to see these on the new camaros - can't wait.
