Tom also has a video of the latest 250 dyno test with the turbo setup on it. Its hard to get good sound quality on a car at the track when your not standing right next to it, so dont let that cloud your decision. You can also check out the July 2010 Car Craft which is already on the stands. Tom is called on to give some expert consultation for a big turbo article featured in that issue, and is mentioned many times in it. I would have posted a link to their site, but it hasn't been added to their site yet. He also is a dealer for the turbo manifolds you need.
