I do like the engine sounds, I have talked Nike Hayzoro through a lot of this modification, the revving sounds are replaces the horns, which is very bad... considering you could spam it (or maybe just make the time long, but that would have to be done with every kart, as if right now the limit of each click is used for all horns), also it does not make sense that you could rev while driving, like what!? So now they should be changing back into horns, otherwise some engines are too loud to hear music on boombox, so I talked him through the update and he said he was done at some point, but I never got the link to the download...
