Hey man :) I tested the 787B sounds and I am happy to tell you that V2 was very good!
The thing is that when you start the engine and let it idle for a moment - at first the sound is like pressing accelerator every 1secs (which is great!) but then after 5-10secs two(i think) sounds start to go unsynced. I dont know if this should happen in the real deal or not, but it kinda seemed strange to me :)
Next thing is that when you let off the gas for example in 5th gear @ 5000 rpm you can hear engine sounds (which is good) but as soon as engine hits 3500 rpm the engine kinda makes no sound (again, don't know if this should happen or not) :)
Sorry for my English :)
The V2 seems very good to me :) i really like it!
Keep up the good job! I hope you will release this sound soon :)
