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

172ktas with free = flowing exhaust, high fuel 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 welcome all = insights and thoughts

Cheers
Christian
