especially in the higher gears at speed which is the main driving environment of the Gumball. I've personally witnessed EGTs creep above 1000 degrees in 2 seperate Zs, once in qman's stock manifold GT2530 car and once again in Seb's inconel sport 535 car. Both times the throttle was open for a good 30-45 seconds in gears 3/4/5.
