Turbo backpressure gauge
If I were wanting to add a boost gauge to measure back pressure on the turbine side, where would be the best place to put it? The heat is obviously a concern, so I need to ponder that some more. This is more for curiosity than anything else...

As long as its before the wastegate the pressure should be constant. You will need to do like the diesel guys and use coiled up copper tubing to dissipate some of the heat before attaching the boost sending unit. Autometer PN 3224 is what you need then your boost gauge sending unit plugs right into that.

damn thats alot of tubing.... BTW, you dont need that long of a tube. My first one was two or three feet, then my second was about 14" long. Both with steel tube. Most factory diesels run back pressure with about a 6" section of tubing. If you think about it, you only need to isolate the heat from the actual pipe not the temp of the exhaust gas. I also found you need a pretty small orifice to "clean up" the exhaust pulses..
