I would assume this process is best used for engine components that run on the ragged edge. Components in top fuel racing are still changed between rounds and I assume this is a standard treatment in those engines. Passenger car blocks still are not race blocks. Everything fails at some point. I believe the process does have merit. It’s not going to change your street car into a top fueler. It’s like a metalax stress reliever in it does work but viewed by some as hokey voodoo. Most top teams in NHRA/NASCAR use a metalax between races on the whole car.
