4oz in an IPA is pretty average, but I dont like the timing of the OP's recipe. I like lots of late addition hops, but the recipe listed is pretty far tipped to the late addition. I would do something like this:
1 oz - Magnum (75 Min.)
1 oz - Centennial - 20 min
1 oz - Centennial - 5 min
1 oz - Centennial - Dry Hop in secondary
If you still want to use your Challenger, I am afraid I cant really advise when I would use them, as I never have. I don't even know if it is a bittering or aroma hop, read up and let adventure be your guide.
