I fitted my rad duct and the radiators and its all fine.   Cowling fits as well..
However the roof of the duct is pretty much up against the firewall.  I am assuming that i need to open the roof of the duct to provide an exit for the air which comes in through the two round holes in the cowling.  Is this correct?  Also I seem to remember that there is a ratio between inlet and cooling air exhaust.  Can anyone enlighten me?
Thanks

Will.
Go to Cooling 101 in the techniques section of my website: www.customflightcreations.com. It was also published in the flier and is on other sites on the web.

Hi Will, sounds like you need to move the duct forward, there should be something like a 1''+ gap between the rear [ 45 degree ] corner of the duct and the bottom of the S/S firewall. Limiting factor is the coolant hoses to the rad' getting too close to the exhaust, they will need lagging in firesleeve and reflective foil oversleeve, [ good thing to do anyway]. Cutting holes in the ''roof'' will only make things worse, the high pressure air in the duct will go up into the cowl and make a bad job worse.
Not very much air gets through the inlets as supplied, Bud's mod's to the cowl set up would be the way to go if you intend to operate in warmer climates. We [Bud and I ] came to the same conclusion at the same time, 3000 miles apart, which is one of the reasons I did my own cowls / FWF Kit. There are pictures of my cowls / baffles on this site somewhere, someone more ''techie'' might be able to direct you to them ?
Cheers,
Nev
