Can anybody think of why Williams has chosen to place the additional heat outlets at the top of the engine cover, either side of the fin? As far as I'm concerned that should not be a very hot part of the car (as opposed to the back of the sidepods where other have created openings), so hot air would have to be routed there? Plus isn't the most important objective in that area to create a clean air flow which then attaches optimally to the rear wing? This surely wont be helped be creating turbulences through hot air outlets?
