CHTs
Posted: Sun Feb 19, 2012 10:53 am
Hi Guys,
I have some concerns about my CHTs still being a little too high on high power settings (above 2500 rpm) even after 5 hrs on a rebuilt 0320 with a metal cowl. They run around 390 and as high as 420 on # 2 which is the front pilot side. Oil temp is good around 185. My guess would be that the bottom exit open is not big enough. So, my question is which is the best way to correct this? I could cut back (actually cut forward) the bottom cowl metal to make a bigger opening (I do have a lip on the bottom trailing edge already) or, maybe I could place some kind of grill openings further forward? I'm sure some of you have already gone through this and may have some advice. I did block off the oil cooler scat hose input on the rear baffle some to increase the oil temp and this did seem to lower the # 2 a little, but not enough.
Thanks for any help.
