I'm building a Dragbike (yes, I said Dragbike) using an 04' RC motor, the question that I have today is about the Airbox; should it be sealed (not actually sealed, but limited on it's air intake), have intake ports, or would it be good with some louvers? If I should be using intake ports, do I want them coming out the front or rear of the motor?

Lol if you want it to be fast it's gonna take a lot more than an airbox. I don't know what you plan on running for ET's but more than likely you will need forced induction.

just building a bracket bike, not trying to run prostock numbers, obviously. Yes, a turbo is a possible future but not right now
