Paul Lamar I am building rv7 and wonder if anyone know's the builder
  of motor mounts that bolt between oil pan and engine I have one and
 plan
  to use it but must modify it as it was built for rv7-a need to find
  angle to place landing strut mount if I can.

  also am interested in your 555 circuit board

  I think the guy went out of biz that was building those mounts.

  I don't recommend those mounts as it puts too much heat into
  the rubber bushings and they are too close to the hot side of
  the engine. That means the motor mount tubes interfere with
  a muffler or exhaust manifold.

  I can give you a dwg of an RV7 motor mount if that is what you need.
  Jerry Hey builds complete motor mounts. He has built several RV7
 mounts.

 Paul,

 What timing location did you use for the location of the P-Port?
 Did you transpose the timing location of the RX-8 side port for the
 location of the P-Port?

 I used this dwg to locate the p-ports. Same as the Mazda Lemans engine.

 You can read the Mazda tech paper on the Lemans engine here.

Paul Lamar,

Thank you for the reply  Yes a drawing of motor mount would
be helpful and I might be able to change the one support tube on the hot
side of engine if too close to the exhaust and I am also thinking of
turbo so
the mount I have might not work ??
Thanks Keith

Here it is.

Thanks Paul  will be a big help  Keith

You are welcome. Let me know if you need any down thrust or side thrust.
The way it is set up now it is straight ahead.
Also this uses the new asymmetric mount that equalizes the loads
on the front rubber bushings that take 90% of the load. It also allows for
a modern large area side mounted radiator core. The rubber bushings
are located directly under the CG of engine prop and gear box.

Also read this for some more background on that type of motor mount.
