Making room for all the wires behind the pillar pod is a bit difficult but, once in place, the pillar pod is secured via two threaded holes in the A-pillar and the job is done. Once the gauges are mounted, the wiring and the plastic tube are connected to the gauges.
PYRO AND BOOST GAUGE KIT SERIES
This is made out of plastic and is designed to fit an 80 Series on the driver’s-side A-pillar, although, in my case, there was a little bit of work to make it fit properly. The gauges will be mounted in what’s called a pillar pod. There is also the option to illuminate the gauges so they can be seen at night this is done by tapping into the parker light circuit to power the globes in the gauges. The boost gauge doesn’t need any power to work, but the pyro requires an ignition power source. Once the dump pipe is re-installed, the pyro sensor is fitted to it and, along with the tube for the boost gauge, the pyro sensor wiring is run into the cabin through a rubber grommet in the firewall. A hole is drilled and then a thread tap is used to create a thread in the crossover duct, which is where the boost pressure will be measured. Then a MIG welder is used to weld it into place.įor the boost gauge, a threaded hole needs to be made for the brass fitting that connects the plastic tube from the gauge to the boost-pressure side of the turbo. The hole is just big enough so the threaded bung fits in nice and snug. A hole is drilled and the area around it is cleaned up with a file or sandpaper to ensure the weld sticks properly. Some aftermarket exhaust systems will already have a thread to allow the sensor to be screwed straight in, but because the one on mine is too big, I have to weld the one that came with the pyro kit into the dump pipe. INSTALLATIONįirst off, I’ve removed the turbo dump pipe from the vehicle so I can weld the threaded bung for the pyrometer sensor into place. This is more important for aftermarket turbo systems, but in any case it’s helpful to know what your exhaust temp is. When it comes to turbocharged engines, exhaust temperature is very important too high a temperature risks damaging the engine and it can be very easy to reach these temperatures under extreme load, especially with a modified engine.įor example, in a stock 1HZ engine, which is a popular choice for aftermarket turbo upgrades, temperatures of 650 degrees or higher can start burning holes through pistons, and those temperatures can be easily reached with 14psi or more of boost. PYROMETERĪ pyrometer is made up of a temperature probe that is installed into the turbo dump pipe and a gauge that displays the temperature. Another possible issue is overboost, which, if left unchecked, could result in major engine damage. For instance, if the gauge shows the turbo isn’t boosting as it should, this could indicate a possible boost leak. BOOST GAUGEĪ boost gauge displays the turbo’s boost pressure so you can check whether the turbo is working correctly. It can be fine-tuned to give exactly the desired amount. The boost controller is connected inline via a vacuum hose between the wastegate diaphragm and the boost side of the turbo, and basically tricks the wastegate into opening at a higher pressure, allowing more boost to be produced. The wastegate on a turbo is controlled by a diaphragm at a pre-set boost pressure this diaphragm will open the wastegate, thereby stopping the boost pressure from rising any higher. BOOST CONTROLLERĪ boost controller is used to adjust the amount of boost a turbocharger can produce. But, of course, there are more things to be done, so in this issue I’m installing an exhaust temperature gauge, also known as a pyrometer, as well as a boost gauge and an adjustable boost controller. Now, with a few thousand kilometres under its belt, the engine is running great and I’m happy with how everything turned out.
PYRO AND BOOST GAUGE KIT FULL
This included a full engine rebuild, turbo and injector pump rebuild, and even the gearbox and transfer case got a look at. A variety of included installation options and direct plug in harness simplify installation on any application.My good old 80 Series LandCruiser had gone through a major refurbishment over the course of 12 months. There is, quite simply, not a better measurement of your exact exhaust gas temperature available anywhere, for any price. The included Type K thermocouple assures maximum accuracy and minimum response time. AutoMeter’s Digital Stepper Motor display combined with our high definition LED backlighting make viewing your exact exhaust temperature effortless. On high output diesel or forced induction applications, there are few gauges that are more critical. Watching your precise exhaust temperature can mean the difference between maximum performance and catastrophic engine damage.
