I've had this problem for quite some time now, every once in a while when the car is warm, I'll turn the ignition, the engine will crank once or twice and then let out this horrific grinding noise until I let off the ignition. If I try to turn the ignition again too quickly it will grind again. But if I wait a couple of seconds it will generally start right up. Yesterday at the track it was really bad. The car grinded three or four times in a row without starting up before it finally turned over.
Now, this has been going on intermittently for well, over a year. I remember it first last summer. Since then I've installed a supercharger, blown my engine, uninstalled supercharger and replaced the short block, and it still does it. So that leads me to believe it is the starter. But before I dump some money on a new starter I just wanted to get some more opinions.
