Hmmmmmm, ... I was discussing this the other day with "Wally 
the muddle headed wombat"  and we were just pondering why on 
earth an FD radiator wouldn't cool a 13B turbo in an aircraft?

It goes without saying that providing of course, you fed it sufficient 
air in a properly designed dukt - that man at that "other place" 
knows how to do it - he's been preaching it for years - nice big thin 
rads).  

Wally reasoned that as they seem to work OK on 300 + neddie 
ekranoplans (aka porsche beating FD RX7's) down Conrod straight 
at Bathurst (130 - 140 + MPH,  albeit in ground effect),  they 
should work in an "ordinary" aircraft as well.  

They also seem to work OK at idle and heavy traffic, even on our 
hottest Sydney daze.  Only downside is that the plastic header 
tanks are known to split,  which can be interesting!  So can you 
please enlighten us??

Cheers,

Leon
