Nice presentation. He's kinda talking to a general audience, and combining turbo charged with turbo normalized. These could be broken down into 2 separate discussions. When he talks abut adding aftermarket intercoolers, he's talking about adding an intercooler to a factory turbo charger system. This has nothing in common with the Hot Shot system. The Hot Shot system adds a turbo to a naturally aspirated engine. A naturally aspirated engine takes in whatever temperature air exists in the environment in which its operated. The intercooler can't cool the air below whatever temperature that is, so can do no harm, and makes no difference to the performance charts. Adding an intercooler to a factory turbocharged engine makes a big difference because the engine is always boosted, so is always ingesting heated air. Changing that changes everything.
Also, he's right about having a manual wastegate on a turbo charged engine - it's a bad idea, but on a turbonormalized engine it has several advantages.
Discussions like this are a good reason for attending the COG fly-ins. It's a lot easier to discuss this kinda stuff in person than typing our fingers to the bone
