Once you can lay into it at
WOT all the way up to 6,500, you should see at least 160HP performance or more.

In my current configuration, I have to limit the throttle opening to about half throttle, to maintain 30 inches MAP.  All along, I've been assuming that this give me the same power as a NA engine using full throttle.  I know there are some losses with the higher temp of the intake, but I wouldn't expect them to add up to that much.

Here's my question- Is my above assumption correct?  I've tried to follow some intake flow discussions in the past on the RX-7 forum, where they were stating that pressure isn't everything.  The idea (as I think I understood it) was that having good pressure registering on a gauge didn't guarantee anything, since the gauge isn't fast enough to show you what's really happening.  They said that if the pipe was restrictive, or there was some other obstacle to flow (throttle butterflies half closed), you wouldn't get the power you should, because the pressure would drop instantaneously when the ports opened.  When that happens, I guess the engine doesn't get the charge that it would appear to be getting from the gauge.  Is this more or less what you're getting at when you say I need to be a WOT to get good power?  

Thanks for all the thoughts.
