Thanks brettman. The reason I ask is because I had my car dyno'd yesterday, as I felt like it had lost some power. Turns out I was right.
Anyway, after the run, they told me how much boost I was making. I didn't ask them at the time, as I had many other questions, but I got to wondering later how did the computer (plugged into the OBD port) know the boost pressure of my LT4 supercharger?
Is the sensor in the supercharger, as on your whipple, or is the data measured from some other location? My question is just for my edification. These things interest me.
