Back Pressure Sensor in O2 bung? I have an o2 bung pre turbo that I was using for closed loop fueling. I'd like to measure back pressure, but I haven't been able to find an easy solution outside of copper tubing coiled around and running to a MAP sensor. Does anyone make a M18-1.5 threaded 0-5v pressure transducer that could screw right into my o2 bung?
Just use the $16 1-100psi transducer found on Ebay with some coiled copper tubing.
I had mine in the #1 runner for a while. When I relocated it to the actual entrance of the turbo (where it should be) Back pressure dropped quite a bit. I went from about 1.9:1 to 1.4:1. This was an S480 on a 370” motor.

If they did make such an item, it would simply be an air cooled, remote mounted device such as what people are making for themselves. Electronics have issues with heat, and solder melts at a much lower point than pre-turbo exhaust temps. Anything else would be cost prohibitive in almost any situation.

Summit sells the autometer one for 14.95 same set up. Its used to hook an oil pressure gauge up per nhra rules(can't use the plastic line that comes with the gauge)
