That first video is deceiving as the microphone isn't actually inside the car. If it was I'm sure it would make your ears bleed! I'm pretty somebody across the pond measured it at around 90dB, but that basically means nothing to me as they didn't state how, what RPM or where they measured that figure. If you open up their PDF catalog its in there, although no proper picture, a quick search through FT86 Club will have pics.
