I am building my radiator shroud. It is a sheet aluminum pyramid out of .062 6061.
I added a 3/4 inch angle frame around the edge on all 4 sides to slide into rad.
I am about to cut the circular hole to put in a duct type thing .
I would like an opinion(s) on how much clearance I should allow between the tip of the blades
and the inside of the tubular shroud ???????
I was thinking of an inch might be enough....... but I figure it will depend on just how much the
engine sways left to right under torque .... (which I don't know how much that will be....... )
I am using destroked motor mounts.
Any thoughts much appreciated !
