well right now i am close to getting enough airflow, i am close to the measurements of the front opening, just gotta be able to spread the incoming airflow a little better from the top of the lid to the bottom. i am in the same boat, i really dont like snorkles sticking out in the open and there is very little room to hide them like on a popo in the pod. i had my airbox ran there but it pushed the plastic out to much when turing hard right, the belt intake and exhaust were ran with flexible vac hose to both sides of the airbox under the plastic which was perfect for me cause i aint going to deep.
