Tom,

Hey Tom;
Ours i= s the 1.06 A/R, and as you can see, we are going straight out the side of t= he cowling.
Boost wise, we have a box of springs for the wastegate, and = will wait for the dyno tests to find out our best settings.  With the = prop configuration we have, we anticipate not a hell of a lot of accelerati= on, until we hit around 120 Knots, and then watch out........(:-)
