One thing I'd like to mention is that, JDM aftermarket VTEC cams were mainly designed for circuit racing (roadracing in laymen terms). I always here people complaining about the high prices of JDM cams and engine parts. People need to understand that these are high quality parts and a lot of R&D is involved. The Japanese are all up on the road course racing tip and not too much into drag. Although, there are a few Japanese drag race companies, but I'm compelled to talk about that. My point is that, when people dyno their cars with these JDM aftermarket cams, such as Toda or Spoon, and they don't see the top-end power that they were anticipating to see, they should know why. Most of these cams are designed for mid-range power, which is needed on the circuit. So, not all JDM aftermarket cams are the right ones for your type of racing.
