There is a good article in the Sept 2002 issue of Sport Compact Car magazine. I checked out their website but no info is there yet. In the magazine it is in the Performance Dictionary section on page 276 and talks about the different types of vi's and how they work. I thought it was very interesting and would pass it along.

 

Damn, you beat me to it. It's good article...not technical enough for me...but a good article.

 

It seems to me that ever since the new editor of SCC came in alot of the technical articles have been dumbed-down. I guess they are catering to the younger demographics that are more interested in how a part looks as oppossed to how it works.
