well i Hope so?
i have problems keeping a friend's car under 970 celsius
0.7Bar boost, he has wrapped header and front pipe with 200 cells metal cat, no mattera what we do, even with 10.5afr and 102 Ron and intercooler waterspray, and ignition timings to the edge of the knock correction, EGT goes high
Fortunately he is going to switch to catless soon, but i hoped you were going to check EGT in your race car, it must be high the EGT with cat, boost and such an AFR
