REFLECTOR: In pursuit of speed

[nmflyer1 at aol.com]

I would be interested on how the exhaust game plays out. Originally, I planned to have my exhaust exit through the back. I even called the prop company and asked if I could do that safely as it seemed pretty close to me. They said No Problem. 
Once things came together, I was going to have very little clearance between the cowl and the pipe and I would have had to modify it some more. I decided to just tuck it out the bottom instead (Picture). 


If there is a real gain to be had by running it out the back, I could change it back later, after I am flying. I'd send the pipes in to Clint and have them make me the perfect "S" tailpiece. Bending 3" Stainless is not cheap, but they can do it perfectly. 
There is just enough room to do that. 


Looking forward to checking out this setup. Last wing will be finish primed this weekend. Painting finished shortly there after and the re-assembly. 


Keep me in the loop please.

I'm half-way there already, just don't have the high compression pistons.  EI 
and balanced injectors, tho.  That mostly helps with leaning it out, tho, and 
getting good fuel economy.  My GAMI spread is very low with everything balanced 
well.  With the EI advancing the ignition, I can safely run LOP.

I saw the same used Mooney turbo kit forsale when I did a search.  He's in 
Boston, too (I'm in MA).  Looks like it was from last year, but I'll contact 
him.

I will likely go ahead with the exhaust, anyway.  A relatively inexpensive and 
easy mod.  A turbo kit would be a much larger project.  In addition to some 
speed gain, I think the inside-the-cowl-rear-exiting-exhaust would also help 
with cooling.  Both by plugging the exhaust holes in the cowling that may be a 
source of lower-cowling pressurization, bit also the exiting exhaust would 
likely create a lower pressure in the cowling to draw out the cooling air, as 
well. 

Thanks.
