Interesting, I asked that question when the engine was being built. I was told no need at this NA HP level.
Also interesting, I asked Kenny Duttweiler about EGT probes just after this happened (didn't know the extent of the damage at this point) to prevent this in the future. He suggested to skip EGT probes, as there is a delay in heating the thermocouples for EGT and by the time you have a critical indication it is too late. He suggested O2 sensors in each primary and a way to monitor it real time. While expensive, I would have probably be at the break even point now if the system would have prevented me making this mistake.
Thanks for the reply!
