Hi, Rusty....curious about the bell mouths/air horns you used. You mentioned that it "really did make a difference when compared to not having any air horn"  Any guestimate regarding rpm or power increase obtained from the air horns? (WAG is fine).   
 
 
Hi Paul,
 
From the notes: 
 
5700 RPM static with the bare TB and the squared off flanges
5820 RPM static with the bare TB and air horns 
 
The flanges were just short extensions that were the same diameter as the TB barrel.
 
Rusty (thinking the current TB might work well for the single rotor)
