Cooling fins

       Remove this ad - become a site supporter!
Hello to all.
I have g-62 mounted and now I find that I need to move the engine
back towards the firewall.Problem is that the cooling fins on the rear of the
cylinder will be touching the firewall.(I may have to remove 3/16'' of an
inch). Question is 1) Can I safely remove some of the cooling fins and still
have proper cooling?
2) How much clearance should I have between the
cylinder and firewall?
The fuse is fiberglass and the engine will be cowled in with a dummy
engine sitting in front.

Thanks in advance

Paul K

How much fin do you have behind the engine. If the engine is side exhaust where most of the heat is retained there should not be a problem as long as you still have some fins. Make sure you have lots of cooling air flowing into the cowl and a larger exit. You can also make a cooling duct to flow the air around the cylinder which is done full scale for the same problem.
