Despite claims, this does not give a ton of extra horsepower. What it does do, however, is gives a greater increase in throttle response and a little more of that “instant power” when you mash the gas pedal down all at once. The engine will rev up a bit quicker and feel like it’s a lot more open through the midrange. It also aids slightly with spool-up on turbo cars. (taken from www.rotaryheads.com)

 

You will only see an improvement in throttle response on Turbos, because they have damped #2 secondary throttles. NA's don't, so there's no change. Power improvement is very small on Turbos, even less on NA's.
