OK I know that this is a long shot... Just had the car dynoed after swapping from AEM EMS to AEM FIC. During the last run at approximently 5k RPM, we developed a loud tapping/knocking noise. Lost oil pressure for a second and imeaeately shut it down. After connecting a mechanical gauge we started it back up, oil pressure good, but noise continued. Assumed it to be an issue with the oil pump/gear. Ordered billet gear, installed and reassembled. Everything that could possibly be inspected while apart was checked. Everything appeared to be fine. Reassembled and fired it back up. Guess what? The noise is still there. It's definitely a rotating noise coming from the bottom end. My mechanic is stumped. Any suggestions? What to check? I have a feeling the engine needs to be pulled and inspected.
