Now that I have a web site, I have received a number of inquiries
about engine mounts. Most people do not specify the width of the
motor mount plate, rather they want me to recommend something. This
has caused a lot of sleepless nights but I have come up with the
following which I would like to hear comments on. The hard part is
avoiding conflicts with potential exhaust systems.
Based on the availability of 2" 90º Stainless Steel bends with a
centerline radius of 2.5 inches from Auto Jet, I believe a Barry
Mount bushing centerline of 24 inches will work for everyone except
those who want to use a turbo. At this width the exhaust system can
be kept inside of the motor mount tubes. The exhaust pipes could
drop down to the level of the bottom of the radiator and still fit
within the cowl. From there they could be routed back to the front
of the firewall and then across the firewall until 32 inches length
was reached. Might even be room for a muffler lying across the
bottom of the firewall.
I can not think of any advantage to having the MM narrower than 24"
If you use a narrower than 24" (mine is 20.5") then the exhaust
tubes have to go outside of the motor mount tubes. No width is saved.
Turbos , of course, need the 30" spacing from Paul's original design.
