I intend to put a belly scoop on my rv-8.  after checking out some snowmobiles I have been playing with the idea of mimicking their radiant cooling.  I was thinking about plumbing the belly scoop by running say 6-8 parallel 3/8" tubes along the belly the 7' back to the scoop and then another set for the return.

 

If you’re going to run tubing back to the rad, think about using the “cool tube” shown at this link.  The stuff weighs about a pound a foot though.    http://www.howeracing.com/radiators/radiators6/index6.htm

 

 what is the consensus of the group about my wacky idea? 

 

Wacky idea?  Welcome to my world :-)

 

C&R is quoting me $700 for a custom radiator, so I'd prefer to buy just one

 

How did you get them as low as $700.  The cheapest thing they wanted to sell me was $985.  I ended up paying $585 for a rad from Howe. 

 

Good luck,

Rusty
