Checking back in.... last august i totally blocked the wastegates off and tried a couple hits to log what the boost curve would do totally unimpaired by the gates. My plan was to hit it and let off quickly just to see how fast the boost came on. Well, stupidity took over and in the attempt to impress my son, I stayed in a little too long and seriously overboosted.... 25 lbs arrived almost instantly and at 24 degrees timing and with pump gas, that dont mix well on a 90 degree night, lol... put 2 pistons into the oil pan. I did a "sloppy mechanics" freshening of the bottom end that included 8 used pistons from ebay, reused every gasket, and literally beat one connecting rod back straight in a vise. The only new parts where a set of rings cause some of them where wrapped around the crank. I tossed it back in with the same bearings and all. It started first crank, with 50 lbs oil pressure and is now happily making power again. 11 degrees timing, 91 octane 20 lbs boost (now controlled by the holley) no leaks, no smoke, no overheating. This engine is truly a warrior. I must say that the holley efi made this about as easy as possible as far as tuning, and the almost limitless i/o's have allowed me to monitor and control more things than most could imagine. This has been a very cool experience. And yes, it is VERY fast. I want to return the car to ford power in the future (coyote) and put the lq4 into a pulling vehicle for the car trailer. You gotta admit though, that the LS platform is hard to beat for going fast on the cheap. Later guys!
