This is in the FSM for the '89 RX-7, those who have the other years of FSM can check their documents and post their findings here:



6.56 psi! There it is. Woohoo. But now that I realize my copy of the FSM is for an '89 I should find one for my car, an '87...

 

Are you sure yours is from an 89'?. It looks the 87-88 turbo FSM.

Here's mine

 

The first page posted is for an S4 (6.56psi boost), not an S5. The second page is the right one for an S5 (8.25psi boost). There's never been a "debate", only a lot of incorrect info posted and a few of us posting corrections. Like this...

Note that those number are peak boost, which occurs abound where peak torque is. It drops by ~1psi by redline.

The numbers are pretty irrelevant though because there's no such thing an FC in new condition.

 

My apologies, by other indicators like gauge layout and other things I noted that my FSM seems to be for an S4, but the lead page (added by the distributor) says it's for an '89. I trusted the wrong signals to my brain.

This leads me to ask though, why isn't the stock boost listed in the FAQ? This does come up quite a bit, that's why I made this thread.
