George,
Mazfix and Mazsport are both boosting to 280hp at the
wheels. http://mazfix.com.au/perfproducts/rx8_upgrades.html.
Pettit Racing is seeing 270+ with 5-8#'s http://www.pettitracing.com/rx8/index.htm
My goal has always been to match the IO540 at 8000ft and have a much
lighter plane with new engine. No doubt I will be giving up some HP without
the intercooler. One percent for every 10 degrees I think. If my
cooling ducts and exit area work as planned I may add an intercooler. The goal
now is to get the engine started and flying by summer.

Bobby,
I would be interested to see what boost is safe
also. You might consider an intercooler!
I assume you are using it on a RX8 engine( i.e.
10:1 ), if so, you could always consider going to 3mm apex seals, if you feel it
would be safer.

Not
much to tell Rob. It's an Eaton M62 4th gen. http://www.capa.com.au/eaton_mp62_4th.htm
My notes show the weight at 25 lbs but I am not sure if that included
mounting brackets. If everything goes as planned I should be able to fire
it up in January. The plan is to use it for normalization or 1-2 psi of boost if
the discharge temps are not to high. It has a 1" internal bypass that provides a
intake air path around the screws so it is yet to be seen what effect this will
have on temps.
Does anyone have any real data as to maximum safe intake
temps with 10:1 rotors and 2mm seals?

Tell us a little about your supercharger. What
brand? How much? How heavy? Have you run it yet?
Thanks.

Subject: [FlyRotary] Re: MAP port
location \
Looks like the
consensus is to place the MAP ports away from the runners. I will try the
discharge duct of the supercharger for both MAP and the Grand Rapids EIS
temperature probe. Looks like the EC2 temperature probe should not be place
after the blower since it leans fuel at higher air temps. It will go after
the air filter and before the throttle body.
Thanks,
Bobby
