Any way you can upload a sound file of this monster?
If I had one, I would. But as far as I know, the car hasn't been fired up in dual-engine configuration. One of the motors was dyno tested in Canada (the photos and links I added) but it was very, very severely muffled. See the link on dyno testing for a photo of the mufflers But. I'll ask Freud to shoot some video/audio of a startup as soon as it's possible. I really don't know when that will be. The liner will be on display at Speed Week (Aug 11-17) but won't run there. Testing is scheduled for "later" but I haven't been given a date yet.
Having said all that, as soon as it's possible to get an audio/video file I will. I'll also see if I can get the same thing for my car when it's at that point. I use a Canon 7D that shoots video, so I can capture that myself. While my car won't have the overwhelming "awesomeness" of 2 blown hemis on alky/nitro, it still sounds damned good.
