Hello to everyone from Prospeed, Bulgaria and I am sorry that my first post will be negative, but it is for your own good.
I am writing this post to tell everyone to avoid Motodyne, because they are ABSOLUTE scammers. We have paid $12k 2 months ago for a supercharger kit for Audi A8 4,2 V8 and since then we had no reply from Motodyne and their "representer"
Robert Hackstetter , who`s real name is Kurbin, Robert Hack. Also we had sent someone to their adress,listed on their website, which is supposed to be 908 East Park Ave, Hainesport NJ 08036. There our guy asked the near shops about Motodyne and he had been told that they were gone for 2 years, because they did not pay the rent. There is a glass shop now in the same adress as you can see from the pictures:

So avoid giving money or doing any business at all with Motodyne and their "representer" Robert Hackstetter ( Kurbin, Robert Hack ) and tell that to as many people, as you can.
And I am sorry if my english is not perfect.
