Lest anyone rush down to their local Chevy parts dept and ask for a

754mm

throttle body, that was a typo.  Its actually 75mm.  Still bigger than a
stock Mustang 5.0 TB.

All this talk about TB diameters for the 20B makes me wonder.  My TWM
Throttle Body ID is 75 mm and seems to be working just fine.  In fact, I'm
getting 32" MP at about half throttle.  Am I missing something

here?  Or are

these 20Bs being adapted to NA applications, hence the need for a larger
diameter?

You have a turbo Tom and turbos make up for a lot of sins.
Have you measured the pressure drop across it at full chat?

Hi Tom,
How's the test program going?  Sure would like a progress report.
