I'll try to get a picture posted when I get back from Copperstate next week.
My blast tube is just a piece of 3/4" wire loom running from the left
difuser in front of the rad, then back to the coils on the firewall.

Got back from SERFI fly-in at Evergreen AL. yesterday.   Ed Anderson, Finn
Lasen and I were there with our rotaries.  There was to be an award
presented for the best auto powered plane there but they unexpectedly
canceled it. When we asked why, they explained that there were no auto
powered planes which were considered worth judging.  Made us feel about as
welcome as a turd in a punch bowl.

There were two Chevy 4.3L powered RV-6s there, one being the Belted Air
Power factory plane.  It was the most professional looking installation you
can imagine.  Sadly, on the way home it crashed killing pilot & passenger .
No details on what happened but weather was apparently not a factor.
