George, my engine mount fixture will handle any engine mount (thus far designed) that uses Tracy's drive. Your bell housing would drop right in. I do like the beam mount but I also like your bell housing and for that matter I like the Conversion Concepts mount too. I believe all are winners. Jerry

Jerry,
The bridge PP is to stop the very thin and flexible seals from being spit
out the hole - but your also spot on with other stuff like overlap.
I claim rights to the first RX8 PP design, but of course everyone can use
it.
I thought you were going with the beam mount as it's your design?
The biggest cost by far is the machining cost, I wouldn't lumber the builder
to do the machining because it must be precise, but for someone with the
skills, they would save themselves money. I'm working on the machining costs
to get them down
For instance Butch will be doing his own and will be testing the design -
for those that don't knew he's an Aviation engineer and my project partner.
He is currently looking at costings as well and will be handling the US
market, so everyone in the US will be dealing with someone they know and
trust. I'm hoping he will get to all the air shows with what ever other
products we develop as well!
We will get there!
George
My biggest concern in costing
Wow, I had not even considered the RX-8, but you are right about the
bridge port. No overlap so it can open early and the bridge
ports can be quite wide too so they will have lots of capacity. This
may be the ultimate engine. Jerry
Ps. George I am looking forward to plugging one of your bell housings
into my fixture. Are you going to deliver the castings with the mill
work done or will that be up to the builder?

Jerry,
Here's the latest - my design for the Rx8 P-Port.
It is a bridged P-port as the Rx8 apex seals are very narrow and
flexible -
not to be used with P-exhaust housings , for obvious reasons.
The green circle is your 1.6 PP.

Suddenly there is a lot of interest in P ports. I think at least 6
different versions are being built or at least dreamed about. There
is
one mentioned yesterday on the other list that will basically be a
race
engine: 300 hp at 9000 rpm!! Trouble with that number is that it
does
not compute. I think 400 hp at 9000 rpm would be more like it. This
is a different world from the wimpy little 220 hp at 6000 rpm engine I
am building.
Anyway, last week I posted a drawing of the intake plenum I
planned
to build but since then it has gotten a lot better. Here is the new
version. The air filter goes where the alternator was located on the
stock engine. Jerry
