got some parts coming to put together a big k&n style air filter with an internal bellmouth. Anyone have anything similar or done anything like this with turbo trail sleds in the past? I know they're a popular setup with the huge boost drag sleds but this will be on a trail sled, just hoping to get a lot of the efficiency back out of the system at 10-12 pounds. Sleds at 9.5 hp/psi of boost at 230 hp, wanna get it to 10 hp/psi or better without huge expense.
