Hi, Rusty....curious about the bell = mouths/air horns=20 you used. You mentioned that it "really did make a difference when = compared to=20 not having any air horn" Any guestimate regarding rpm or power = increase=20 obtained from the air horns? (WAG is fine).

Hi=20 Paul,

From the = notes: =20

5700 RPM static with the bare TB and the squared = off=20 flanges

5820 RPM static with the bare TB and air=20 horns

The flanges were just short extensions that = were the same=20 diameter as the TB barrel.

Rusty (thinking the current TB might work well = for the=20 single rotor)
