In any case a sudden change of temperature should not be cause for an abort and exactly how much temperature change constitutes an abort decision?
I think you have been corrected on all issues raised Tee Emm, but just to emphasise, in addition to checking the temp. on applying takeoff power, it is wise to check the pressure to make sure the application of power hasn't forced a pressure loss somewhere. It shouldn't take 5 seconds, RPM, temp/pressure, airspeed increasing is about 1.5 seconds and its better to have 500m of tarmac infront of you when you spot a problem, rather than the blue yonder.
