A 1-per-rev sensor should be no problem for FPGA (or WPILib) well over 11,000 rpm.
If there's a high-speed limit, it would be in the sensor itself. That's why I asked him to post a picture of the wheel with the tape on it. If the tape doesn't cover a sufficient angle of arc, at high speeds the pulse width may be too small for the sensor to detect reliably.
