Re: The Turbonator !! :)
mmmm..done a bit more surfing for info & may want to tread carefully on this one. These are posts from other sites:
Keep your money! It's a scam.
I've done a fair bit of work on air flow inside a cylinder, and I can assure you this will have no effect whatsoever.
There are two types of helpful airflow in the cylinder: swirl and tumble. However, you really want laminar airflow up to the inlet valve. The tumble and swirl atomise the fuel as the mix is drawn into the cylinder on the piston's downstroke, and the pattern of airflow is only affected by the angle and shape of the inlet port, and the position of the valve.
This is a nonsense. You'll see no gain. In fact, it will probably slow your car down as it is effectively a blockage, reducing the area of your air inlet.
