Good idea, but unfortunately TA doesn’t sell that even though they did a design for a Bonanza in the past.  They don’t seem to have much data on it and the information I’ve receive on the LML is far more complete.  The one photo I’ve been trying to have resent is not showing up, but I am beginning to think that a different design is better anyway.  Jeff Pelletier sent a photo that shows it  top down to pretty good effect and Pete (leapfrog) sent a drawing that I think describes this solution.  It involves a similar hole cut in the oil cooler box wall but it has a scoop that opens up inside the oil cooler box at the top.  See the photo and drawing in attached emails.  I think the scoop can be easily made from graphite – wet layup or pre preg whatever you’re comfortable using and then bonded or riveted/screwed or whatever to the box.

I think getting some additional air flow down the oil cooler box might greatly improve the airflow here.

Turbo Alley in Ada Oklahoma has a baffle system design with the back baffle having this hat built already into it.  I have only been told about it and have not seen it yet.  I'm thinking about buying that one piece and replace the one I got from Lancair.

Legacy & still building

Hello all,
 
In April I asked some questions about this issue of  managing the cooling flow for #2 cylinder and there was a prolific and enlightening response that helped a lot.  The most common piece of advice was to build what was termed a “hat box” in the forward wall of the oil cooler box to allow more air around the back and bottom of this cylinder.
 
Someone posted a photo of that fix and it was excellent.  Now I’m ready to go to work on this project and I’ve searched my data bases in different computers for that photo for a couple of hours to no avail.  I’m hoping that whoever was kind enough to post that picture will resend.
 
Thanks in advance.
 
Regards,
