Dan Before I mounted my cooler under and behind the engine, I was going to mount it flat against the firewall ( or about 1 inch or so off it)and use the fire wall as the outlet, allowing the air to run down the firewall and exit out the bottom.( with a light guard) OR I was going to mount if on it's edge, on the firewall running along side the cowl, with air inlets as I have on my cooler now, and have the outlet through the back edge of cowl on one side, and add exit slots like you see in the Vintage Car bonnet. I would seal outlet to cooler with foam, so the cooler would not be removed with cowl.
I would have braced the cooler to the firewall and off the engine mount. Phil Matheson VH-PKR Australia KR Web Page www.philskr2.50megs.com http://www.vw-engines.com/
