Interested
in supercharging your A3 VR6? Do you have a enough tools to be dangerous?
Well, maybe you can build your own kit, and help other's do the same!
If you own an A3 VR6, you most likely are quite aware of your options as far as forced induction is concerned. If you interested in a super charger, your choice are very limited. This page is an attempt at providing you with the information necessary to buy all the parts to build a complete VR6 super charger using either a Vortech V1 or V2 charger. For those computer geeks out there, this project is similar to the Linux operating system... it's open-source so everyone can contribute and make it better!
This page was created to pool information regarding the building of a Vortech-style supercharger kit. Not only do we intend to address the fueling issues, we also hope that you will be able to create a kit for less money than you can buy it.
Phase I: The Parts List
Create a complete listing of all the necessary parts to build the kit. This includes everything, from the blower to every screw or nut. In addition to a part list, we would like to list where each part can be purchased, and hopefully get some deals along the way.
Phase II: The Online Manual
Once we have the list of parts and a few people have bought the parts, it's time to create an online installation manual! No more bad Xerox copies of instructions!
Obviously, in order to make this project work, it will require your help! Please contribute this project via our forums, and we will try to gather the usefull information here.
