Help on a 95 12 valve
#15
The blow off valves came around for these trucks when everyone was running a HX-40 style charger. The 40 due to surge issues and very basic compressor and turbine wheel design had a serious problem with powerfull surges breaking the shaft. BD came up with their BOV for the HX40 trucks that were fueling hard. While the newer chargers are more resistant to surge and shaft problems, Surge is still a problem. In the lower HP ranges it's not really required and with a properly designed setup surge is less intensive.
Unless you've had one shaft break already I wouldnt even look at a BOV
