Yea you read that right... vortech is releasing their own twin screw. I must say it looks like a whipple with a vortech sticker on it.

Looks exactly like a whipple or the S/C on the GT500's..... isn't lysholm the one that pretty much started the Twin screw business in Europe and now they divided off and came to the U.S.

I read a long thread on this in the boost and juice section and I think i am going to try to find it and clear up my confusion....LOL

found it! long story but here is a link and a part of that thread that is stickied in the boost and juice section

This is where it gets tricky because they are all interconnected:
SRM liscensed twin screw compressors as early as 1951
SRM formed a sister company: Opcon Autorotor.
Opcon Autorotor parted ways with SRM.
SRM formed Lysholm.
Lysholm formed a partnership in the U.S. with Eaton.
Opcon bought Lysholm.

Kenne Bell uses Autorotor Compressors.
Autorotor is a subsidiary of OPCON, a swedish company.
OPCON bought out Lysholm in January of 2004.
Up until 2005, Whipple used Lysholm Compressors. Now, Whipple makes their own.

Kenne Bell and Whipple have been in competition with eachother since roughly 1991 however they both use a very similar design. Kenne Bell explains why it chose to use Autorotor compressors over Lysholm in the following article this page.
There was a backlog of Whipple orders and rumors that the company may be going out of business. It turns out that Whipple has since moved away from lysholm compressors and now manufacturers their own units in-house.
Here is a great link from Whipple's site on the history of the twin-screw: History of the Twin Screw.

Regarding Lysholm's future:
"The demand for our products on the US aftermarket remains strong and a new sales organization will enable us to meet the increasing demand and further develop the existing potential in the US automotive and Marine aftermarket. We will further develop our distribution channels and our support for these products in the US," says Martin Stenbäck, CEO of Lysholm.
