This is a picture of the Engineair cooling system at SnF.
This is a 350 HP to 400 HP turbo small block Chev V8.
I always kid Jim Rahm when I see him at air shows.
I tell him the reason it is living is he has replaced all the 
Chevy parts with aircraft quality parts such as 4340 forged
crankshafts :-) His latest comeback is he has gone beyond aircraft
quality :-) So far they have about 400 hours on it. We shall see if
it passes 1000 hours with out overhaul.

What you see is only half of a symmetrical cooling systems using
two identical large area thin radiators. There is another set on the
other side of the engine. It is working very well
since I saw a customer version  at the very hot Copper State AZ 
flyin last year. The heat exchangers at the front are two identical 
intercoolers for the single turbo seen towards the rear. The electric
fans are used for taxi and they claim they are not needed for climb.
A real well done cram job in the stock Lancair IV cowling.

Several of these firewall forward packages are flying with identical
cooling systems and layouts. One of them nearly won the
NC to OSH race last year. I think it came in second very close to
the winning factory Lancair IV with the expendable engine and prop.
