Perhaps you are right, b= ut perhaps not

The fact that there are failures in c= ars may or may not have relevance here

The assumpti= on that a particular piece of equipment has no effect on any other piece of e= quipment in an aircraft can possibly shut down an important thread of inquir= y that may be a safety issue.

Where on the bolt did it happen

Hey all
Just thr= owing it out there.
What's the thoughts on small production of engine mou= nts to suit the rv6,7 for the 13b renises, also cowls, and efi and turbo set= up to suit.
Also bell housings.
My 13 b is currently out to get some c= racks repaired on one of the gear leg mounts, ( cracked due to the gear leg b= eing to stiff) Plane currently has approx 700hrs now and was going well.
= All temps were under control.
Small history
13b renises pp
Custom e= fi
Modified james cowls

172ktas with free flowing exhaust, high fu= el burn
155 Ktas with restrictive exhaust under cowl

Plans

= 13b renises with turbo with small boost
Simple new efi
Neil's new Psru=
Bellhousing to suit
Radiators and all gear to fit the rv

I wel= come all insights and thoughts

Cheers
