I own a dp2quattro, I don't use it since I switched on a pro sony camera, but I am currently thinking about to reconvert it into a texture scanner, with a cross-polarization system.

If I remember well, this device with its leaf shutter can achieve high synchro speed with flash, wich would help me to take pictures with flash in outdoor conditions with very short exposure time.

Does anyone know how fast I can go ? I will need to find a way to use a ring flash I think.

According to the Imaging Resource review, it's up to 1/1,250th at f/2.8, 1/1,600th at f/4 and 1/2,000th at f/5.6 (or smaller, presumably):

That assumes that your flash duration is shorter than those speeds, of course.

Those are the maximum shutter speeds for those apertures and because it is a leaf shutter flash can be at those speeds too.

What if there's some delay in the activation of the flash?
