Weather; Aircraft
We were set to depart [and] it was a hot day with ATIS reporting about 34 degrees Celsius. On the inbound flight the crew wrote up the airplane for an ENG EXCEEDANCE; which was due to an ITT (Inlet Turbine Temperature) over temp on the #2 Engine. Mechanics met the airplane and after a visual inspection and clearing of the message signed the aircraft off as airworthy. We pushed off the gate slightly delayed. Push and engine start were all normal and we continued our taxi; at which point we were cleared for takeoff just as we were pulling up to the runway.I was the pilot flying and the FO (First Officer) was pilot monitoring; the winds were from 080/10. We started the takeoff roll; at 40% N1 the engines stabilized and all parameters were normal; so we continued the takeoff roll.At 80 kts the FO called '80 kts; thrust normal;' during my quick scan off the EICAS I noticed Engine 2 ITT was hovering around 950-955; but I called checks as it was still in normal operating range. As we continued the takeoff roll the right side ITT continued to creep up; and at 100 kts the FO called the ITT exceedance; a quick look at the EICAS showed the ITT gauge in the red. At about 105 kts I proceeded to call the abort; and applied maximum reverse thrust and brakes. We maintained centerline and slowed down; at 80 kts the ENG EXCEEDANCE caution message came up and we exited the runway. Once clear of the runway I called the FA's (Flight Attendants); and made a PA to the passengers; it was also at this time that we got a BRK OVERHEAT message. The left brakes were in the yellow range at about 440-450; the right side brakes were at roughly 280.We then proceeded to contact dispatch and maintenance; and were advised to return to the gate. During the extended taxi back the brakes had sufficient time to cool back down into the green range. The mechanic that met us inspected both brakes and tires and noted everything to be normal. Passengers were deplaned as were told the airplane would be grounded for the night; and we waited for another airplane to arrive.
EMB-175 Captain reported rejecting the takeoff on a hot day at a high elevation airport when the #2 engine ITT was exceeded.
