No, internal in the engine, and even internal in jack, there is no limit (or at least it is at 3.4028234664e+38 which is the maximum value which could be represented by a float)
Some plugs just start to sound nice, when they are heavily overloaded.
The limiting to 1 - (-1) becomes true just when the signal enter the sound-card, so the level control (Master Volume) is there to do this limiting.
The included recorder plugs, have a clip detector and a level control, so you could limit your records to don't clip, even when you record directly after a overdrive plug, before the Master Volume.
