reverse bonnet vent
hey just a quick question, is it better to keep the original scoop on the car forcing air into cool the engine down or is it better to have a reverse scoop letting the hot air out as ive got a FMIC

It was quite alarming to see the heat rising out of the engine bay through the reverse vent, it was similar to heat haze as you could literally see the hot air escaping from the vent.

I've tried finding it myself after reading it a while back, the one thing that I would say is that having given the car 'the beans' over the weeked up at the Colin McRae weekend that the vent does seem to perform a valuable function.

I think the thing to remember is that Harvey tested a reversed scoop and not a reverse vent which will if properly designed will draw the hot air from out of the engine bay, something to do with the vortices (possibly vorticees) which are created by the air flow over the vent.

But if I could make the below and have the best of both scoop and vents.
Also has anyone noticed how much their bonnet scoops (particularly the Blobeye) flex/move when at speed when on 'private roads'.

I've got a FMIC at 400BHP but still run a Bug STi scoop.................because that's how they should look
For Track / Drag / Rally / time attack applications there may be good reasons to run without a scoop but for looking like an impreza and making people look twice in the rear view mirror there is no substitute
