Default Little bit of extra weight

If a car weighs around 3800 and another one weighs in at 3600 and you were to race these two with the 3600lb one having slightly less than half a tank of gas (16 gallon tank) vs the other car being full tank (17.5) and having around 70-90 extra lbs in the trunk does it really hurt that heavier car that much more?..

If the 3600lb car can beat the other one by around 1 1/2 cars would removing all of that extra weight be noticeable and close the gap by a bit or would 120-140 lbs not make a difference at all?

Dropping weight will definitely help... it might not even them up but they will be closer... probably a 1 car loss instead of 1 1/2 (obvious no way to know that but just as an example).

generally 100# = .1 ET in a 1/4 race

as to MOV - that would depend on how fast the cars are

1 gallon of gas weighs about 6lbs, so 7x6=42lbs and in the other 105lbs

so.. 3642 vs 3995.. whats the deal with the person racing with cement bags in his trunk?

don't let anyone make excuses about full tank + stuff in their trunk.. that's ricer style excuses. full vs half tank you are talking about a 50lbs difference generally, no big deal really. yeah if you are chasing an ET at the dragstrip you'll want to shed every lbs you can, but in street racing it wont make much of a difference. if you lose very slowly where they are inching away on you, yeah you might have wanted to take the cement out of your trunk.

but a full tank vs half full tank, maybe if you had a 90lbs jockey driving your car you'd win too eh?

I was really just wondering If weight could really make a difference in a street race once the cars are moving, I remembered that 100lbs did equal to .1 at the track and supposedly .1 is like a car length..
