I have been considering the gearbox plate with the integrated mount points to replace the heavy beam I have now. Also an alternative way to attach the rear mounts. My rear mount is attached to the back of the oil pan. No way to drop the pan without removing the engine. I would also like to make a thrust line change to eliminate a large rudder trim tab and improve level flight characteristics. The mount weights 32lbs with oil pan. Way to heavy.
I've become very aware of how much high frequency noise the super charger produces.

The mount will leave virtually the
entire cowl space open (to the point of: no place to hang heat
exchangers up front :-) ). If you decide to make a big change like
that, give me a shout off-line & I'll point out a few more
things that could make it better the next time around.
Progress is slow, as usual. Life continues to get in the way.
Current project is the oil cooler mount. I'd use Dale's, but I
want to avoid the remote mount with its extra weight & oil
lines. I'm pretty sure I've found a way to use the stock tower
& avoid any bumps in the cowl. I'll post pics if it works out.

Thanks Charlie. How's the project progressing? I'm still
thinking about a turbo and relocating the radiators for a
cleaner airflow.Â

Do you have any pictures of your engine mount you can share? Particularly the lower rear attachments to the engine block. I remember you had a unique solution but I don't recall the details.

Bottom view below. Note that the square tube that connects the
two 'tripods' on the firewall side would have been more
functional if it had been welded between the two adapters,
with the sleeves welded to the two 'tripods' on the firewall
side. The reason is that the square tube would have provided a
hard connection between the two adapters, removing any risk of
'racking' load on the bolts/studs attaching them to the
engine. That's how I'd have built it if I'd not been too dense
to picture what Monty Roberts was trying to describe while I
was designing & building the mount.
The adapters are *way* overbuilt; most of the parts could have
been made from .062 instead of .125 4130.
