To quote the auricle:
The possibility of actually running a few IHRA events, using them as test sessions, has been considered but not considered ideal. Tasca also doesn't know if the IHRA could accommodate NHRA racers showing up for their events.
“I don't know what IHRA's position is on it exactly, but it is an option. We would prefer to test with the guys we race with. We would prefer to do a test session with other fuel cars of our class, one it gives a good indication of what they run versus what we run.
Good to know that someone struggling in their first year of an NHRA pro class considers themself to be better than those pesky IHRA racers.
