I have to agree with both of ya'll on this. His videos to lack substance and I'm almost 100% certain its because 99% of his viewing audience wouldn't understand that much technical information. Also keep in mind people have short attention spans these days. They want instant gratification. So basically tell me what motor your testing and show me the HP. That's all. I'm not a regular viewer of his channel, but I have heard him say heads or intake were CNC ported. Right then it would be good to know if they flow 200CFM or 400CFM, especially if he's talking about an NA motor. I do think the engine masters guys do a better job of discussing more technical items.
