Hi  Everyone,

This is my forst posting so please bare with me if I get  something wrong.
This is just a simple question regarding the 20b and  aluminum housings
available from www.racingbeat.com.

1 - Will these  "fit" the 20b engine
2 - Do these require machining or are they ready to be  used as purchased 3
-
The baseline for my aircraft is the Lycoming  IO-360-A1A which I believe is
certified at 328 LBs. Does it make "sense" to  spend the several thousands
of
dollars to shave about 50+ LBs off of the  20b (assuming these housings can
be used) Any arguements against using  these items reliability wise

The aircraft is an Osprey  GP-4.

Thanks a bunch. Can't wait to see the replys.

1. Three out of the four housings can be  replaced by RB aluminum housings.
2. no machining is required. 3. I would  use a 250 HP RX8 p-port 2 rotor
cast
iron engine rather than a 3  rotor
20B. The firewall forward weight would be about the same  as an IO-360.

I've had the same question on my  mind:

"Any arguements against using these items  reliability
wise"

We don't have any track record with  these alloy end housings. The RX8
P-port
is a minor variation of p-port  engines that have been used for 30 years.
