T1 Race Development Exhaust Backpressure (EMAP) Damper Kit
Monitoring exhaust backpressure is one of the most useful things you can do on a turbocharged engine.
Exhaust backpressure allows you to see a variance in your engine's efficiency (can be caused by boost leaks, wastegate problems, turbo problems, etc), allows you to see how well your turbine housing/wheel is sized for what you’re doing, and allows you to monitor when the turbo is maxed out (if you know what you’re looking for), etc.
Unfortunately, doing so is difficult to do cleanly and easily. Because of the heat and exhaust pulses present in an exhaust system, you need to use a reasonable section of coiled hard line between the exhaust and the sensor to protect it from the heat. This is both inconvenient and hard to do cleanly. In addition, doing things this way will get you a very rough signal, as the exhaust pulses will make it very difficult to make useful without very heavy filtering in the logging software. Filtering also causes delays, which you don’t want.
This kit allows a clean and simple install while providing good heat protection for the sensor and by dampening the pulsations, an extremely smooth exhaust backpressure signal with no filtering is available.
