What is this sensor on a 930
I am trying to figure "what's what" on my newly acquired 911 with a 930 motor.
Is the red sensor below a "boost pressure sensor"? I noticed there is not a wire on the other pole. The wire that is attached goes to the coil. If it is the boost pressure sensor then should there be a wire going to a gauge? btw, I don't have a manual to refer to yet. Thank you, John

That's the boost pressure sender. Not sure why it's wired to the coil. Does the boost gauge work? BTW, it should only have one wire just like the pic shows. It should be connected to pin #13 on the 14 pin connector.

I'll double check, but pretty sure it was connected to the coil. I was being distracted by an inquisitive 3 yr old...
 I also saw this "green wire" bare. Is there a replacement for this or is the general consensus to just repair th section.

The green wire needs to be replaced if the casing is broken. If you have the two prong plug get this: Pelican Parts - Product Information: 930-602-907-01-M14
If it goes straight to the CDI get the 928 version as it's about 30" long and you can wire it straight to the CDI:Pelican Parts - Product Information: 928-602-907-00-M100)

it's not connected to the coil just kinda disapears into the wiring harness near there. yours looks like it's connected correctly.

No idea. I was only started briefly and shut down. It has a few ignition issues that need to be checked and squared away. I am almost embarrased to ask. Is the boost gauge the one with in the tach or the one to the right of the speedo? Ask me about a mid year vette... I'm so embarrassed to ask that. I need to do some reading... is all I need to say.

The one under the tach. The other one you have is aftermarket and I think more accurate also. My original is not working and stays full boost all the time.

Actually, it could be both. Clearly, the factory gauge below the tach would be present and the clock was sometimes replaced with the 934 style gauge as well. Some cars one or the other is the only functioning boost gauge. Other cars have both functioning. I tend to trust the 934 guage over the standard. Pic stolen from someone else's thread ...

Great helper! that engine must not smoke much since you have ancillary mosquito abatement hanging on the rear panel.

Okay here are some pics. Some are from a phone others from an slr.
It's a "driver", but that's what I wanted. No worries from stone chips just adds to the character...    polished Fuchs        When it's clean, I'll do some decent pics. |

Hmmm. I would keep 'helpers' away atleast the time the hoses are open. You don't want to be sorry later if something funny is found on your turbos compressor wheel  Think: "Superman toy likes to go to investigate the black hole" |

Nice looking car. I seeyou have a Dial-o-Death on the center heat control. I'd be very weary about using that, as it's been known to cause instant engine damage. Do you know what boost spring you have? What's the 2nd dial on the heat console?
