Well what do you expect? In a country that is dominated by V8 Motorsport, Auto Salon is a showcase of what can be done with asian cars. There are a few workshops that get into it (Gas, ESP etc) and good on them for it, but besides bragging rights, there's not much incentive there to do it at all... Most of the entrants are sole entries that have put their own time and money into it, so it can only go so far... John (RH9) is just one guy, he doesn't own a workshop...
Not to mention a tiny population to start with
It's going alright though, I don't know how many Auto Salons around the world have had a car crack 1000kws live... It gets better every year
