Hello Mr Lamar,

I'm contacting you for more information on the Mazda rotary intake
manifold and parts you sell. I found your address on the Tracey Crook
site. I'm putting a Renesis engine in my BD-4 mounted with a Jerry Hey
mount. I would appreciate any information on products you sell that
would help me.

We sold out of manifolds years ago. I now advocate p-ports for all aircraft engines.

It is too expensive to make side port manifolds for all engines as the RX8 is different than the 13B. Actually there are two side port configurations for
the RX8 alone. A six port high power side port and a low power four side port.
P-poerts are easier, cheaper and the engine breathes better so the fuel burn is slightly less and you get more power.

This is a simple how to. If you need it done Jerry Hey can probably do it.

If you don't need more than about 160 to 180 HP a cut down stock RX8 manifold would probably work. Just don't expect a lot of power. If you want to weld your
own four straight runners about 22 inches long that will give you about 200 HP
at 7500 RPM. Try this configuration. It puts the ram air scoop outside the cowl like an ME109. I assume you are using a 2.85:1 gear box.
