That's a relief. I would not put it in the category of "structurally
sound". Several critical tubes are missing.

The hidden beauty of the redrive plate mount is it gives you
plenty of room for the turbo.

The easiest and cheapest thing is the Schertz beam mount.

Make a sectioned drawing of the front end housing as there are
some unresolved issues with oil drain back, oil pump mount and oil feed to the
main bearings. It would be easier to do with an external oil
pump. Richard does not yet have these issues completely resolved.

I will trade you some more detailed pictures of the cut away
stock front end housing if you promise to send me the ACAD R12 section drawings
of the front end housing you do. :-)

Paul, I think Conversion Concepts is doing a great job, just not for me :), maybe when someone has
the ultimate mount they can share it with them and everyone will have a great mount vendor. 

I totally disagree I have seen three version so far and all suck.
the man is a great welder and marketeer but a lousy structural engineer.

No one
of us can make all the solutions.
I have said nothing publically about the Shertz beam but personally I would not go there. Lets put
it this way, many many people had misgivings about the structural sanity of the oil pan mount idea
hanging the engine off a bunch of bitsy little screws (I'm fine with it), now you are advocating
doing it with 1/4 of them? 

Six 6 mm bolts will take about 15,000 pounds in shear. The main 6 G load
is downward so the engine presses down on the Schertz beam. The bolts
don't enter in to that. They only come into play when 1 G thrust or lateral
load is applied. The diagonally braced version is even better.

At least if you put the beam on a GEN 3 there are motor mount bolt
holes down under there. (mine are epoxy filled due to use of a gen 2 small wedge pan).

Agreed.

The redrive plate mount is OK but a truely good design would take a hogged out oil pan plate,
extend it to the redrive mount, bolt the redrive mount to the plate, put the rubber mounts where
you want, either on the pan plate or the redrive plate. May need a clearance cut for the ring
gear. This is a super strong and lightweight design that is also gyro proof (even Tracy would like
it). 

Over kill and expensive but it sounds super safe. Go for it.
Never the less it gives me an idea. Bolt the Schertz beam to the pan.

If I do not get anywhere with the dynafocal I will do this route.
I don't want a red hot turbo anywhere near any engine mount tubes.

That is what heat shields are for.
In that case I predict you are going to wind up with a proper cantilever mount :-)
As in this drawing. Paul

I will gladly share anything I draw that is mine and I feel is to my standards.
I need to get a full understanding of the front plate and front housing, what each does as a
feature and function so that I may address each to include or find an alternative.
