i heard that drilling some holes on the lid of the airbox gives you a little more airflow and a little more mph is this true or just a waste of time and of a lid?
1986 Honda Spree w/ pulley mod clocked in at 37mph hauling 175 lbs. Don't believe me? lets race!
I've tried this and I lost so much torque it was worthless. drilled out my exhaust and opened up the intake (read: no airbox at all) and the thing was gutless.
