For those of you who follow on here... went drag racing Friday night. It didn’t like the top end at 20 psi. Specially when I was launching in second on the way home. 🤪 oops. Undetermined what the noise is yet. I assume top end. Others think bottom. Meh. It’s been there for 2-3 years under hard boosting. Finally got worse. #ford #turboford #jackstands #turdblow #knockknock #whosthere
