the intake manifold already has a supercharging effect from the factory

You didn't read any of it, did you?

It is all talking about negative pressure, being as powerful as positive pressure.

This new info is going to change how we make power on engines in the future.

yes. stepped exhaust will give you more horsepower and torque. it costs a lot of cash though. and whoever is building the exhaust would pretty much have to custom make it for each car. and when I say each car, I mean not an rx7 and a camaro but every rx7 and every camaro unless they are bone.

The Negative Pressure Supercharging concept was first conceived 1983 in Sydney Australia by Alexander Chabry, a 21 year old self-taught engineer with a remarkable insight into the fluid dynamics of the conventional 4-stroke engine. He was inspired by the fast acceleration produced by the low revving 225 Chrysler slant 6 and the massive towing power (torque) produced by heavy trucks. He figured cars could use low rpm torque instead of high rpm horsepower to substantially improve acceleration and fuel economy.

1983 was not a long time ago, for an entirely different approach to making power in an engine.

You are extremely ignorant on this subject. You fell hard for marketing gimmics, this is simply SCAVENGING and has been around long before you and me put together.
