motorjock205 Posted March 16, 2008 Report Share Posted March 16, 2008 I've noticed what actually sounds like detonation pinging in the engine when I'm under hard acceleration...I've never owned a vehicle that has roller rockers, so I'm wondering if this could actually be what I'm hearing? Of course, I'm actually hearing impaired after 30 years of shooting guns in law enforcement...so it's really hard for me to pin it down..I don't hear it when I'm sitting still, only when I'm driving...I know I get more sound from the Ford Racing Air cleaner setup, but this kinda concerns me...I'm running 91 or 93 Octaine fuel, so I'm sure it isn't actually detonation... Anyone hear anything like what I'm describing when you romp on your ride??? Link to comment Share on other sites More sharing options...
