It has become apparent to me that there is much that isn't

understood about the Callaway turbosystems designed for

A1 (MK1) Volkswagens. That is why I decided to create this page.

The Goal here is to document the facts, as well as maintenance

and adjustment procedures while throwing in some

cool old articles and stuff.

With that said, lets get to the point!

This is a Callaway System on a Rabbit GTI

(the purple thing is a Greddy blow off valve I added - not original callaway)

After a recent makeover on the car, it hit the rollers again putting down 200hp at the wheels.
