So I really never liked the Kitfox cowl how it dumped the hot air from cowl out the bottom air outlet and right onto the radiator.  I cut the scoop off and turned it upside down and glassed it back on. Pretty it is not , but functional yet so far. I had too much fun flying to get to finishing it yet :) We use to have a saying in the drag racing days back in the 70s " if it don't go => CHROME IT " Well mine works well and I try to keep the colours consistant somewhat <chuckle>

Now i had to still  get the air out of the cowl so I took a  2 litre pop bottle for a mould and cut it in half and taped it to the bottom of cowl and put over it 2 layers of glass.  Then I cut openings larger in the existing cowl.  I dropped 10 F +  right away.    But looking at the front I still figured that some air  was caught in the boundry layer and might be missing the rad all together so i put on  8 vgs and temps dropped  10F again. 

 Basically I had not had any heating issues other than 180F cruise   @  70F  or  80F   but on climbout I would see 190s  when i had on the IVO medium on wheels before the mods.

On climbout now  at  90F  I never see over 180F on climb out and cruise   160 to 175F average  at  88mph   on King fox wheels

I flew last 100 hours on amphibs with the mod and seemed OK........  Just got a layer of bondo on it and I might finish it one day,  heck I might even paint the mod  :)

I have also pondered the idea of using a shutter on the radiator but have never got to it yet. It would hopefully hold the rad temps higher during long decents . I find that according to my Watertemp gauge that 160 to 180F cruise I have no issues I have seem temps 190F to 200F on occasion and have never had any engine issues. I am on my third 582 now and approaching 300 hours on it since a new install in 2006. I have seen more cold seizure issues from too much cooling and adding full throttle to a cold engine than I have on engines that run at 180F So i can only assume that what I am doing is working for me well.

Kitfox VG test report --soon to come
