It may be possible to get to 125 wheel hp, but it will likely take a long-tube header (which does not exist as of yet) and underdrive pulleys (assuming they are worth power). Your typical CAI, axle back and this intake will be closer to 115 wheel hp.

sorry Richard,maybe i am just getting to excited. instead of an axle back how much hp can be gained from full 2'' header back exhaust.
