Budget Travel - 1:30 enough for Ryanair at LGW?

Will be taking the train in from London Victoria and was wondering if 1 hr 30 mins will be enough to drop off a check-in bag, get visa/PP checked, clear security and get to the gate.

This is for the 13:50 DUB flight on Tues, Apr 17.

It's enough time if things go perfectly. It's not enough time if they don't.

Bag drop closes 40 minutes before scheduled departure time and you have to get your boarding card stamped before you can go to the bag drop.

I'd allow more time as with Ryanair being a second late WILL result in being denied boarding..
