Friends,

Hypot= hetical question.=A0
Let's say it's a standard day and I&= #39;m at sea level.
I've installed a turbocharger and have also connected the stock au= tomobile turbo boost gauge, along with my traditional manifold pressure gau= ge.

I ground-run the engine to full throttle (where the MP = would normally be reading 29.92- minus some efficiency loss) and the boost = gauge is reading 20 psi.

What should the MP indica= tor be reading?

Thanks!

Pat
