Anyone know the formula to figure wet torque if only a dry torque spec is given??

There is not a formula. Type of lubricant will make a difference.

It can vary......imagine the differences, oil, copper anti-seize, nickel anti-seize....etc.

As well as materials.

Materials and surface finish make a big difference, too. Torque is a very complicated issue, and specifications are best based on test data and past experience with similar joints.
If testing isn't practical, I'd go with 60-80% of the dry spec depending on the application and type of lubrication.

Even if there is no stretch on a bolt it can break from the twisting force trying to tighten it because even a bolt that is too long(bottomed out in a blind hole)can break from too much torque.
