Subject: RV8-List: Re: Sealing Around Engine Baffles

Matt,
I say horsepucky!
Install your engine baffling.  Go fly the airplane.  Then spend  hours 
putting red RTV in every crevasse and fly it again.  You will notice  there is

no difference in your CHTs or Oil Temp.  None.
Now - if your goal is maximum speed, then you will want to pay more  
attention to sealing the air cooling flow since it produces 30-40% of your  
overall drag.  But, if you are trying to maximize speed, there are more  important

things to do to reduce cooling drag than filling every tiny opening  with 
RTV.  Making a plenum is more important.  Improving the exit air  flow is 
more important.  Optimizing the intake/exit ratio is more  important.  Once 
those are done, then sealing all tiny openings with RTV is  the final step.
I flew my RV-8 without RTV sealing the baffling and then sealed it  
carefully with RTV.  Zero difference in any temperatures.  None.
