I liked the Grand Sport ever since I saw the first one at Pebble last year.
Thanks for this video!
But what was that sound of like high pressure gas escaping when he got on it?
They were remarking that it sounded great, but I found it really annoying.
Maybe it sounded different to them.
Was that excess pressure coming out of the 4 turbo waste gates when he
got off the throttle?

Wastegates dump pressure from the hot side of a turbo into the exhaust system. You can tune the wastegate to open at a certain peak pressure point in order to regulate the spooling of the turbo and therefore the amount of boost pressure it produces.
Blowoff valves release the pressure created on the cold side of the turbo when the throttle plate is abruptly closed. Most turbocharged production cars vent the blowoff valve/s back into the airbox to muffle the sound. The ones that don't, like the Veyron, produce the "whistle" you heard in the video.
I found the video amusing when they kept referring to "the sound of four turbos" when what they were really hearing was the sound of the blowoff valves releasing the air when the driver would get out of the throttle. Oh well...
STLMOTORSPORTS - Must be an enjoyable job you have. A quick lap in a Veyron would be quite the thrill. I'd only suggest a shielded lapel mic for any future videos you intend to make. That would eliminate a lot of the background noise heard in the beginning from the wind and the traffic.

Great videos as always, Adrian! I had a chance to see the twins a few days ago, and then again yesterday. On my way out, I saw one of them at that detail shop off of Long Rd. - do you guys get work done there or was it just visiting? Always wondered if they did good work.
