So... I have a 600+rwhp 5th gen and my buddy (this guy has been friends with me for life) has a bone stock v6 5th gen. In his drunk state one day I foolishly left my car running with door open as I went to say bye to another friend and he jumped in my 5th gen and took off down the block..... He put it in paddleshifter mode and pretty much redlined it down the block and around and back.... about a minute or two or straight red lining while burning the tires off.... My shift points are slightly elevated as I have a blower cam and in paddle shifter mode it will let you redline up to I believe its 7200rpm or so....
Results....
We are still not sure if it did any damage to the piston. We are replacing the 1 spring and hoping to god that the internals are fine. As stands it was about a $500 "joy ride" but if there's internal damage I am really debating whether I should tell him something because it would be 4-5k in damages. Remember though, this is my best lifelong friend.
