I didn't know they were going to play these samples, but for the record yes they are from the dyno recording sessions that we are using to create the sounds for the game (they
are also available for download on the official PGR3 site).
The final RPM sweep on the Skyline goes to 8000RPM which is the redline for the car and we recorded an 8000RPM sample for use in the game.
Things are still being "developed" but when it is finshed (and hopefully before release) I will (if allowed) post some audio recordings from the game so you can compare.
It will hopefully meet your expectations
