Does anyone have the turbo radiator installed in a model A cowling? Where did you put everything? Did you vent the top of the cowling?

Thanks,

Sonex-715...trying to get restarted building..

Not a factory install but you can look at mine if interested.

I have flown about 70 hours now on this setup and it works great... The cheap fan is still working fine,
whilst a little underpowered, it's still satisfactory for lowering the turbo temp post shutdown. I realise the fill point is not ideal but I just run the pump when filling or checking the coolant level. Works fine.

Sorry for the delay in responding to this! Flickr recently changed their policies and forced me to remove/relocate all of my Sonex photos. :-/

I've got the Turbo Cooler system put into an Album on OneDrive now, you can view it here:

• The key thing is to ensure the reservoir is at the absolute highest point, or you'll get air trapped in the system.
• Since I have the air-oil separator on the left side of the firewall and I didn't want any leaking coolant to spray onto my RDAC, I resolved to place most of the system low down on the center or right (passenger) side of the firewall.
• An important thing with this layout is to ensure that lines stay at least 1-2" from really hot things, like exhaust pipes.
• The radiator position I settled on is not ideal, but I figure that its main job is to move fluid and assist with heat transfer *after* shutdown; therefore the fact that its not in the main airflow path inside the cowling is OK - especially with the fan to force air through it.
• My custom radiator mounting brackets put the radiator at about a 60-degree angle to the firewall, to ensure there is room for air circulation (via the fan).
• Note: I have yet to make first flight; so I cannot say what kind of performance this solution has yet!

Enjoy,
