I had a problem with Eventuri plenum not making induction noise from 4k rpm all the way to redline. I contacted Eventuri and sent them some clips. Turned out the resin on my plenum lid was too thick. I could barely press it down with my fingers. The sound is made by the carbon lid reverberating and mine was hard as a rock lol. Eventuri quickly resolved this and sent me a new one which is much more flexible. Something to look out for if anyone is in the market for one.
