[QUOTE="31BCobra, post: 15088425, member: 87741"] Okay so for anyone not following my build thread, I did a Fore level 2 fuel system, and upped the boost on my 2.3l Whipple to ~24-25psi. Whipple said it should be okay for the redline I was at, so I went for it. Car performed well on the dyno and aside from a squeaky belt on cold starts the car runs really well. Today I started her up and I hear this knocking noise at low RPM. The noise became more pronounced as the car warmed up and is noticeable at idle and low rpm, but goes away as the rpm raises. The sound seems to be coming from around the Whipple mostly, but I am not 100% sure on that. Used a screwdriver to try and find the source but as far as I can tell everything sounds normal. Here is a video. [url]https://www.youtube.com/watch?v=11EAeVa_ZbY[/url] [/QUOTE]
