The compresor faces forward and  a cone shaped K&N filt= er is direct mounted to the compressor housing.

So far the turbo muffles the engine fair= ly well.....but I have not gone to War Emergency Power.....yet.
I 'borrowed' David Leonards radiator advice, and mounted it under the chin= , making a fairly generous scoop, which I tested today.
the oil cooler is mounted on the right side and uses the en= tire airflow from the right cowl cheek opening. Separate air paths for rad= iator and oil cooler helped solve my previous cooling failure.
