[QUOTE="speeddemon2000, post: 15525623, member: 14576"] That's crazy. On my first motor I did several high speed runs up to 170, it wasn't till I got greedy and started using nitrous that I saw issues with the pistons and the damage was no where near that. Can you post the pics of the other pistons? My guesses at this point would be, oiling issue, next a cooling issue or a bad injector. I think the only way the tensioner melts like that is lack of oil. Maybe all the debris from the piston clogged the oil pump pickup tube. Pull the oil pump off and check the oil pump gear. The gears will shatter into a million pieces. Lack of oil supply would explain the issue with the tensioner guides melting. You could have also had an issue with the cooling system. A small leak can cause big problems. I always turn the heat on high during pull like this. I would also insure you have a temp gauge. The factory gauge will only show hot after the engine has already melted down. Pull a part further and post more pics! [/QUOTE]
