Stopped in yesterday to take some pictures of Buly's fine airplane.
The finish on this airplane is a sight to behold. It looks like
a world class racing sailboat hull. The sanding is superb as is the rest of
the work.  A sure fire winner in any workmanship contest.
Not only that... it is cooling very well indeed with a small size radiator
record.
Buly took a stock all aluminum racing radiator and cut it in half.

IMHO the reason it is cooling so well is due to the P51 style scoop under the
fuselage with a boundary layer air bleed and the back side of the rad is
totally
unobstructed. It is no slouch either in the speed department at 200 MPH
with a normally aspirated side port 13B Cosmo engine.

Paul,  Buly

Could you tell me the dimensions on the radiator? I am assuming Buly's
engine delivers around 220 Hp max.

Doug Fir

I think his engine is more like 190 HP. It is only a 2.17:1 to gear box.
My guess is:  10" by 19" by 2 inches. What is it Buly?
