GM LS engine - motor mount/PSRU

[Reed Britt Civ 309 MXSG/M]

I have attached some information from EPI - Basically seems negative about
the V8 concept from a weight perspective. $5,000 seems like a lot for a
motor mount -



I also contacted Vestas V8 and asked if he had any experience with Murphy
aircraft - Apparently he has one or two under contract. He has a firewall
forward setup that he quoted at $28,500 including the cowling, psru,
radiators, computers, mount - mostly everything - He will not sell the motor
mount separately.

Before committing to an LS2 / gearbox instead of the M14P for your Murphy
Super Rebel - 3500, I suggest you consider, in some depth, the information
presented at the following links:

.......Price and availability on a motor mount.......

Price is time + materials. Typical is in the $5,000 range for a
one-of-a-kind. I'd need detailed, accurate drawings of the firewall,
cowlings, and the supporting fuselage structure to which the mount attaches,
as well as your specification on the longitudinal placement of the
powerplant. If my analysis showed that the fuselage structure is
insufficient for the loads, I would decline to go further and charge you
only for time already spent.

..... and a Mark 15?

Castings are in process. Availability probably late this year, in view of
current orders. Price depends on ratio; targeting $8500. Don't know for sure
until finished parts are in hand.

Sincerely,
