Barber takes their noise samples at 100’ from the track at 104db. At 100’ we’re good.
Unlike NCM track which is less than 50’ from the track and right after turn 3 where the 500 shifts into 3rd.
Info from email response from the barber track.
On FL500s I just heard of people going to dealerships and getting the new filter and being told they don’t have the FL500. I could be wrong and if they are interchangeable maybe dealers just decided to keep the new one.
To all 6.7 guys. Ford did away with fl2051s for the 6.7 diesel. They replaced it with fl2124s.
Also the fl500s is replaced with fl2121b12. Anyone living near Conroe tx the O’Reillys have plenty of them. Went to 3 O’Reilly none have 2051s however all had multiple fl500s filters.
I thought the firing order in the 00R was different than the 99/01 cobras. I have been going through boxes of old stuff and I found a booklet about the 00R engine when I get back in town I’ll try to remember where I put it.
