Why do Top Fuel dragsters not use turbos?

Why are Top Fuel dragsters so loud?
Top Fuel dragsters are the NHRA’s loudest cars, in part because of the way the engine is mounted. The NHRA once allowed a team of seismologists to stand at the starting line to measure the race the way they would measure an earthquake — the two cars rated a 2.3 on the Richter scale [source: McGee].
