T1 Race and Development - GT1R Exhaust Back Pressure Damper Kit for Nissan GTR R35 VR38
Quick Overview
Monitoring exhaust back pressure is one of the most useful things you can do on a turbocharged engine.
Exhaust backpressure allows you to see a variance bank to bank (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.
The GT1R EMAP Damper Kit includes two custom dampers which attach to the back side of the cylinder heads and get exhaust pressure input through the secondary air ports in the exhaust ports. This kit allows a clean and simple install, with good heat protection from the sensor, and by dampening the pulsations, an extremely smooth exhaust backpressure signal with no filtering.
The sensor port on the damper is 1/8” NPT and any absolute pressure sensor will work. We offer 5 bar (up to 58psi exhaust backpressure) and 7 bar sensor options (up to 87psi exhaust backpressure).
