So to start with, the turbo starts with lower compression so
that you can
turn the screw in and make boost without hurting the engine.
Then you turn the
screw in some more to make up for the intake with no tuned
lengths. Then you
turn the screw in some more to make up for the dreadful
restrictive exhaust
header and turbine. Then you turn the screw in some more
because this pig is
supposed to be stronger than the NA engine. Then you turn
the screw in just a bit
more to account for the extra 47 pounds the turbo
adds to the plane. So how much
boost is that exactly?
I have no Idea. A
guess might be 8 to 10 pounds.
Hi
Lynn,
Thanks for the
message. This is probably a good summary of the losses that have to be
made up by the turbo, but I sure hope you're guess is wrong about the amount of
boost needed to break even. Anything more than about 3 pounds to
break even will be more than I will be willing to live with. I can
at least skip one part of the problem, since I have 9.7 rotors.
Thanks again. Good
luck at the race. Maybe you can improve that #20 position in the next few
runs.
Rusty
