Hi,



Gary Vogt mentions a mod to the wraparound metal baffling for Cylinders 3 & 4 , we are working on getting our High CHTS under control and attacking it step by step.  Flexible baffling work is finished and has helped ~ 20 degrees.



Gary mentioned trimming of the wraparound cylinder baffling for # 3&4 that helps with the cooling of those cylinders?  Anyone have details on that.



We have a O-320-E2G engine (77 Cheetah) with the 150 HP HC STC and short stack powerflow exhaust



Thanks in Advance



Cheers,

Bill Chambers

What Gary is talking about is opening up the AREA on the bottom side of 

the cylinder for less restriction and more air flow around and through 

the fins on the back two cylinders.  IOW, shortening the end of the 

baffle that wraps around the back side of #3/#4.  You will have to ask 

him about how much, probably .75-1.0 in.

Bill

Trim about 1 inch, maybe an inch and a quarter from each strap.  Then cut off the corner (about 1/2 to 3/4 inch on a side) on a 45 degree angle, with the open end toward the CHT probe, then bend down the last 1/4 inch as a tab for the safety wire to tie the baffle together.

By-the-way, keeping the straps tight agains the cylinders is important.  The #4 cylinder strap is compromised by the rivets on the baffle and the arrangement its riveted.  It really needs a cover around the outside to close off the sides.

I think I have pics on my web site.  Restorations page, look for baffles.
