Turbulence Not Working

I’ve set up turbulence but it isn’t doing anything to my text? Do my settings look right?

Explosion is driven by particles movement.
Turbulence force field will have an impact on trajectories of particles.

But facts that particles are numerous, emitted at right moment, moveable… : all of that depends on particle settings.

To sum up : if you disable turbulence force field, you should have an explosion, anyways, if default settings of particle system have an initial velocity.
If it is not the case, that are your particle system settings that are wrong.
