Gut it man, toss the useless weight away and install this with ducts running to your air intake (testing your fabrication skills haha). You'll get something like +35% compressed air on the 986. See first few plots.

Always wondered why the roof area was used by the performance guys (ruff, mirage cgt, etc). It just never made any sense to me (roof?!?) until I saw why like you guys did.

I want it! Maybe with two channels - the other to feed an air to oil cooler

I saw a 2nd gen MR Turbo with a roof scoop like this and it was sweet!
