Two things:

1.  You may not get good IR results from the D800.

There's a quick and easy method to check wether the camera is suitable for IR Photography: Take a picture of the IR-diode of a remote control while the command button is hit. The resulting photo should display aan alit diode.

2.  You need to do some research, as the results you get are dependent on the filter you use.  The R72 is a popular choice but it does pass a little visible.  Using this fact is what allows R72 images to be post-processed into images with the pale blue sky.  You may have seen such images.  Although interesting they aren't B&W, which is what you said was your goal.  Of course you don't have to do this kind of PP, but the IR effect of the R72 is a little less dramatic than images taken with a deeper IR filter which passes *no* visible.  IMO.  See the Lifepixel site for more info on a dedicated conversion and how their various filters render a scene.

You are right, but you can achieve "dramatic" shots in pure b&w with the R72 too by just desaturatiing the colored areas, the yellowish sky in this shot :
