That sounds normal so far. The camera sensor is sensitive to IR, but that is normally not desired when taking normal photos so there is a built in filter to block it. When you add the "IR filter" that blocks visible light and only passes IR. After the two fight it out, there is enough IR left to make an image but you need more exposure.

You need to increase the exposure a LOT. Looking at a random old test shot I have, I was using 2 seconds f/8 ISO1600 on a 50D and Hoya R72 filter. That was in semi-cloudy sunlight. Of course you may need to vary that for your exact circumstances. Also try live view as that can give an image for you to see to compose with and may help with the metering too.
