Or at least that's what rFactor calls it.
I found this file in rFactor that was making a weird sort of ray gun type noise in the sounds folder: https://www.dropbox.com/s/bc7qt2r7ffep7jl/pithorn.wav
So I deleted it.
I used to hear that sound in all the mods, but now it's only in the Endurance Series mod.
Do you guys usually have this problem? And how might I fix it?
