Does the vent behind the main rad suck cool air in or drives warm air out? Never actually thought of that.
Did you find his book a good read. Quite some people find it being not technical enough. I thought it was all I needed to know, a side from some details like one way valve on the power steering vacuum, PCV valve alterations,... .
I think that is fair reasoning.

The engine is a Lotus built 2.2L four cyl. It's tilted over 45*. The stock turbo was a AiResearch T3 "50", and it suported 228 HP non-intercooled, and 280 HP for short bursts if the car had the intercooler installed. The time of the short burst seems to coincide with the time it takes for one coolant lap thru the CC system.
My car was originally non-intercooled. I installed the extra CC, computer, pump, header tank, pipes and radiator.
The turbo I have now is a T3/T4 hybrid.
The radiators are in a diverging area duct where the CC rad. is up front, then the A/C condensor, then the main rad. Behind that are the fans. So the air is pushed thru the duct, then sorta dribbles out the back.
Ahem..
Right now, my car has the oil cooler in FRONT of the CC radiator. I did that knowing that I'd change it later. This does not work on a hot day in Seattle!
So now, I'm in the process of changing all the plastic over in the front to move the oil cooler(s) to separate ducts on either side of the main duct to keep it from polluting the CC rad. with heat.
As an aside, some friends in Thailand (VERY hot over there) have custom built CC rads. to get rid of the heat in the CC system while toodling around Bangkok. So the rather large stock CC rad. may still not be perfect.
I think Bells book Max. Boost is good from an installation standpoint. His way of sizing the charge cooler itself seems to square nicely with what Lotus came up with stock.
Cheers.
