This last weekend a NASCAR Cup car over revved. They changed the valve springs and raced it the next day. Engine lived. I know our cars are not meant to last at those engine speeds. My point it to share that the part(s) they saw as most effected were the valve springs.

True but this NASCAR cars are made to do 9500 RPM the Gen 2 5.0 can barely do 8000 RPM. As I said my engine is running as it should but it's losing oil I will know more when my dealer check it on Friday.

Dealer did a compression test and filled it with new 5W20 Motorcraft. I did 110 miles drive on the highway with it trying to vary RPM's and the oil level was stable. No Missfires or Codes on the computer as well. I think I dodged the bullet but will try to keep an eye on oil consumption.
Next event is Dracon Speed Cup R2 27.04 can't wait to see what it will run with the A052's there.

Track-Speed released the official video from Serres if you are very careful you might see the blue Mustang in that sea of supercars
