Theoreticaly with 5s 4350 (78300mWh) you will have 8% more energy on board when compared to your 4s 5000mAh (72000mWh) battery pack. But on the other side your car will need more energy (higher top speed ...), therefore i would expect the temperatures to rise somewhat. Runtime will go down somewhat too. But as you said not by far.
