Manifold pressure with Ray Jay

[Dick Denenny]

I have a 1966 M20E with a Ray Jay turbo. Just curious what kind of manifold pressure anyone with this is getting say around 12,000 feet?

Thanks, Dick

20” at FL250 add 1” every 1000’ down give or take.

+1 this. My 65E with fixed wastegate (not RayJay) holds 30” @ 12K
