How much can I spray on stock fuel system?

It all boils down to fuel pressure and the AFR. I recommend a fuel pressure gauge and a dyno session to not only check AFR under load but to monitor the fuel pressure drop under load through out the RPM range of the dyno runs.
Jet the shot for the max you want to spray, then check the AFR as the Dyno run progresses, watch the fuel pressure gauge for maximum drop. As long as the two are in acceptable parameters you are golden.
I'm currently spraying a 100rwhp shot (Dave's 78mm dual stage wet plate) that is actually netting me 124rwhp on the dyno with a stock pump. My stock fuel pump is pushing 64lbs at idle, I've been told it should be 58lbs.
Good luck!
