Anyone monitoring exaust gas temps? If do where would you mount the probe? Wondering if this is feasable and how accurate.

What are the benefits of monitoring EGT. Mainly for engine safety or tuning?

Its good to monitor you EGTs when running these modified boosted engines. If you've ever seen what happens when these engines run lean you get the picture, cooked valves and pistons. There is always the potential for one cylinder to fail due to a bad injector, when monitoring AFRs most (if not all on our machines) are monitoring somewhere near the end of the exaust manifold or a header. This gives you a combined reading of all three cylinders, so if one sees the AFRs out of range they typically adjust fuel by changing injectors, fuel pressure, or duty cycle of the injectors (rude controller). This usually affects all three cylinders at the same time, no way to adjust per cylinder. The EGT monitoring gives you another tool for monitoring lean conditions or excessive heat. It would be good to have the ability to monitor AFRs and EGTs on each cylinder, at minimum it would be nice to monitor each cylinders EGTs.
