Unless it's a hybrid the burst disc can't possibly make it stronger... louder maybe.

Correct me if I'm wrong...

Combustion acts like the "valve" in a combustion launcher, and takes several milliseconds to take place. If the pressure is contained until it reaches the desired level, then the "valve" is faster, so it should increase performance if done properly.
