Try not to hit any cars on the first lap. On the start of the second lap on the mulsanne straight watch you top speed as you approach the first chicane. After you exit the chicane pause the game and write your top speed number down. Then as the race progresses you can watch you speed to see if it changes from lap to lap. I normally verify my top speed in all LeMans races on the start of lap 2. If I feel my car is slowing and if my lap times don't look right, I check it for top speed as I just explained. I always try to remember to check it again on the very last lap. Granted traffic can prevent you from checking your speed as you a busy dealing with overtaking a car. But that will verify to you what SwiSwe is saying. If you do a big slide or are even hit from behind only you might experience a drop off in top speed which because the lap is 85 percent at full throttle in real life  I seem to recall reading somewhere, the impact of a top speed reduction is massive to your lap times.
