Racers do not work with the weight of their cars to get top speed. They try to drop weight to obtain maximum accleration.
The weight of a car will not affect it's top speed. Perhaps your rig, since the inconsistancies in the road as it rises and falls and the inability for the truck to accelerate with any zeal at that kind of speed makes it impossible to reach a top speed as though you were unladen. Also, adding 30,000lbs to the load adds friction to the 18 wheels your running. Commercial trucks already have significantly higher contact patches than cars, do to the need for extra loadbearing capacity. Making every one of those tires squat, even the slightest bit creates more scrub and friction. That could reduce your speed a little.
Put solid tires on your truck, and take it to a perfectly smooth road, and it wouldn't care about the 30,000 lbs very much.
We currently have the technology to accelerate us to 97% of the speed of light. It's quite simple. It uses a nuclear fisson reactor. Creates a nuclear split, and forces the waste out the back. Unfortunately, the compartment would have to be heavily shielded, and about 2 miles away from the reactor.
