Chrissi (building rotary Cozy IV) just sent me an email
that has me wondering.
She suggested that I might be going lean at high power
because I'm running 4 * 550 injectors instead of the stock 2 * 550 and 2 * 850.
I hit a "brick wall" in the power curve at a certain rpm beyond which I get a
"stutter" feeling which listeners on the ground report as a "popping" sound.
I've been thinking this is the edge of detonation and avoiding it. Maybe it is,
but perhaps it's because the injectors have topped out rather than because of
excess boost.
Thoughts, anyone?
Anyone have a couple of 850 injectors I can
try?
