Hi there, I have a couple of questions I would like to bounce off of you guys.

01

I have noticed that there is quite a bit of space in some of the exhaust tunnels and wondered that if one was able to add tubing to duct air more efficiently through there (thus not increasing FA) from part of the radiator to the rear of the vehicle. Would a ram-effect of incoming air be strong enough to carry air at a higher pressure than atmosphere to help fill the low-pressure at the back of the vehicle or would these gains be quite negligible?

I know there would still be losses, but if this system was well made, would one be able to supply the rear with more litres of air than a normal clean underbody would?
