I know elephant racing makes finned oil lines...
Reviewing the internet, lots of places sell finned 3/4 inch brass and copper oil line...
example:
Fin Tube Manufacturers,Copper Fin Tube,Copper Alloy Fin Tube,Copper Fin Tube Manufacturers
Seems it would be really easy to splice this in, and braze/solder for additional cooling...
Anyone ever done that? Seems pretty easy to do... thoughts?
