>> The firewall itself does not carry the thrust forces. The triangular chocks
 at the engine mount attach locations transfer those forces into the
 fuselage.<<

...Always wondered what those triangular chocks with the bitty holes on the
firewall were.

Was wondering if a firewall reinforcement (engine mount attach points in the
firewall) is practical considering my hypothetical notion regarding a 200HP
on the 320. I 'm also a little curious to know if anyone has placed a 200HP
on a 320.  I think, via Internet a while ago, a fellow had built several
320's with a 200HP and has/had them for sale or sold. If it is totally
discouraged than that would be nice to know also. In addition, forward thrust
forces between a 180 and 200HP was not my major concern (or should it be my
major one?) Torque, asymmetrical thrusts, hard landing forces with added
weight of the varr.pitch prop, and CG did come to mind. A 58 lb. vari pitch
prop more firewall forward with the ext. mount seems fwd heavy. And yes I do
recall V2=3DV1 x cube root (hp2/hp1)...Twice the speed wanted eight times the
HP needed - cool perspective!  BTW, is the LML archive accessible to it's
members?

thanks!
