All,

 

Last winter I installed a plate in the lower cowl that covers most of the nose gear leg slot going forward from the gear leg (I left enough gap to allow for the gear leg to flex).  I found that it did reduce some cowl drag, but at the expense of engine cooling on hard climb outs.  As today was standard east coast hot and humid, I took the plate out.  With the plate out I noted a 10 to 15 degree cooler peak CHT on a hard climb to 8500'.  I also again noted a knot or two off my typical cruise setting.

 

So - winter the plate is in, summer the plate is out.

Interesting,

 I have heard another builder report cooler climbs doing this too.  I  have a plate and now Iâ€™ll have to test this on my 10.

  

 Thanks for the report.

Great feedback! I just pulled my plate for cooling troubleshooting. 

Wondered if it mattered. Now I know

Thx
