Correct. But you could always isolate it and raise the rating with a $30 manual boost controller if you had to...


So, what do people do with a 1 bar spring? Ground it and cross their fingers?

Are you even tripping it, or just trying to anticipate problems?

The factory test for the switch is to pressurize it with an ohmmeter across the contacts.

If it reads open (infinite resistance) at 1.5 bar, and recloses somewhere between 1.1 and 1.4 bar on the way down, that's all good according to the factory 930 manual.

If your wastegate regulates properly at the 1 bar mark, you shouldn't even trip an in-spec switch by the look of it.

And I wouldn't be depending on that guy too much to save you either (mine's disconnected).

Get a manual boost gauge and watch it, or an EBC with an programmable overboost cutout...
'77 S with '78 930 power and a few other things.
