G'day Paul

Do you have any information about the Greddy inlet manifold? I am going
to fit a new exhaust to my plane and then, if I am still short of power,
a new intake system.

I have asked Tracy his opinion on the Mazda igniter failures. If it is a
heat problem I will have to fit some blast tubes for them and the
alternator.

I have heard noting about the Greddy intake manifold. In fact it
is news to me. Don has a machine shop buddy out in the bush that
can make you some RX8 P-port rotor housings.

I kind of doubt it is just a heat problem. Cars sit around in
110 F over here in the summer idling with the AC on. Sounds like it has
something to do with the continuous high RPM. Check the current
drain. Maybe I can borrow an RX8 coil from Mazdatrix and run
some test on it. Dave Lemon has an RX8 and perhaps I can put
a clamp-on amp meter on the coil wire while it is running
at a steady 6000 RPM. Or I can do it on mine if I can
get Robin to help.

You might need a 15 or 25 watt dropping resistor.

Do you have a scope out at your hangar?
Are you still in the same hangar?

IMHO Mazda made too many changes in the RX8 motor and they
are now paying the price :)
