The sounds were based off of the sounds of the RX4 from MAT.
Trust me: if you think those are bad, just wait until you hear the RFB.
I'd agree with the video being shitty because 1) My pirated copy of fraps is old 2) I didn't take the time to make a good vid and 3) If you saw till the end you could tell I was playing on mute game audio while blasting music.
Good to hear some feedback. I'll upload some pics.
