> I really wish I
knew how much boost the 9.7 rotors would tolerate. If 6 psi is safe, then
I'd be tempted to just set the relief valve there, and try to adjust the
throttle for 5 psi.
I just asked my engine guy (Japtrix) this question. He
feels that the engine (9.7 rotors) will be fully protected with a 6psi popoff
valve and the stock wastegate. He seems to think that manual
wastegate control is unnecessary. He once drove an RX7 up a 12,000ft mountain in
Peru. As they neared the top he felt the boost drop off. It came back as they
came back down the other side.
For what it's worth.
