I am not Jbright but I am temping at 190 to 200 on my Full Mod. It gets 10 mins easy in my T 2.0. I pitted at 9:30 yesterday and made the next 10:30 easily. I did a dry run test and it made 12 mins to completely dry. I put a new plug in before the main and then checked it after, it looked almost new, just a light gold tinge on the face of the plug. The tune is very close, where before it was too fat on bottom. The plug face was brownish black and the coil was becoming pull distorted. I could not ask for more out of this engine.
