i think with some more octane he could squeeze some more hp out of this by advancing timing a hair but as far as the turbos, no one knows yet. this is the farthest anyone has pushed RBs yet. there is still the stock intake tract restriction to deal with and you can only push so much air out of this housing before it becomes a restriction too. have we reached that yet? we'll see soon.
