No one seems to discussed the
stock waste-gate controller. This is what I plan to use. Should be
more hands off and still produce good boost with some safety against boost
creep. I also have a greddy pop-off valve but haven’t decided if it is
needed. I may not install it.
Todd just provided
an excellent drawing of the system he's using, which includes the
stock wastegate actuator. I may try the same setup that he has,
but I will need an actuator with a spring that's closer to 3 psi than about
6 psi. I'm sure I can modify one, but I want to use the manual lever
long enough to prove what the wastegate can do. I also want to
prove how difficult it is to maintain a particular boost level with
the manual lever. I suspect that it's going to be a full time job,
which would be better left to a normal actuator. If it turns out to
be simple, then why mess with an actuator at all. Lot's of testing to
do.
I have the 9.0 rotors and a well-fed
intercooler so I plan to run a little higher boost if I want to. I also
have an IFR panel so I could climb above 18k every once and a while. Would
I need to? – almost never. But no one has mentioned one of the big
pluses of the turbo… bragging rights J What would 36 in. MAP at 21K get us
in terms of TAS? Of course – 30 min of endurance is not that great but you
only need to gather the numbers once to enjoy bragging rights for a lifetime

9.0 rotors are standard
in the 3rd gen engine, and mine is happily running 13 psi at sea level.
Many run more than that, so you should be good to go. I would still
like to get other opinions of what I could run with 9.7 rotors.
Lynn, any idea? John, thanks for asking your
engine guy.
