Here's what I ended up doing, I took the air off the back of the #3 cylinder baffle, routed it forward right up against the cowling to the heat muff on #1, then the heat muff discharge is nestled up against the sump/block to come back aft to the heat door. It was a little interesting getting it in there but that's the only way I could get it routed with what I considered to be acceptable clearance from the exhaust heat.

Built an off-plan 9A with too much fuel and too much HP. Should drop dead any minute now.

Default Scat Tube Run

I just finished my Scat Tube run with IO360 on RV-7A. Photos are here.

I put stand-off heat shields on my exhaust pipes to protect scat tube from their heat.
