A buddy of mine ( Brian - owner of Nine Four Motorsports) took his Chum/Champ Team to WRL a while back. They were doing well with a number of podiums and trophies in Champ, but found they were not quite "on the mark" in the WRL.
Then, last December they took delivery of an NP01. They won at Road America complete with Red/White/Blue livery!
Here is a short YT from the drivers Mike & Jonathan:
