(Thread Starter) |   Not Ranked : 0 score  Prosport: Inches of Mercury? Prosport Electric Boost Gauge Model: 216CLWAEBO270PSI  InHg or PSI... or both? Does anyone have the same boost gauge that I have? It says both InHg and PSI, but there is only one scale on the face. Is it really PSI, and just a misprint? |

| Not Ranked : 0 score no its right the inhg is your vac reading and the psi is your boost reading. its the same as my greddy your in inhg through vacuum then you go into boost psi.

(Thread Starter) | Not Ranked : 0 score That's weird. I had no idea. Anyone know why that is? On the Dashhawk and AccessPort, vacuum is still measured in PSI. |

(Thread Starter) | Not Ranked : 0 score Okay, so I just read some wiki stuff on pressure, and its says that InHg is typically used for fluid measurements. So why the different units on air pressure? Was it just done that way 100 years ago so nobody changed it? Or does it make sense and I can't see it? |

| Not Ranked : 0 score I don't think that I've ever seen a boost gauge display negative psi. I'm sure that they are probably out there, but most read vacuum in InHg...

| Not Ranked : 0 score because vacuum and boost are not read the same typically. with out a turbo motors are vacuum only, but you throw a turbo in the mix and now you are forcing air therefore bringing in a new type of measurement. |
