Twin turbo your mustang they said. It will run great they said. Yea, so much for that. I had this weird issue where if I got on the car one in 4th or 5th gear, it would be rich, 10.1-10.3 AFR's, but then if you let off and hit it again, it would go to like 13.0. I would immediately let off of it, but someone told me that my wideband sensor was prob just delayed and the AFR's shouldn't be changing. So last night it hit 13.0 and I swear, I missed it for only a second, but that was it. Ton of smoke out the back, running on 7 cylinders, game over. And when I say ton of smoke, I mean TONS of smoke. She's laid up now and I don't have the time or resources to fix it right now. It still runs and starts up so it's not completely trashed. Just needs a nice set of forged internals. So FML. Now she's up for sale. I'm not giving it away though. If it doesn't sell, I will just leave it laid up until I can afford to do a short block. And that ends my rant. Good thing I have a reliable daily beater. Edit 11/12/13 Car is now apart at JPC. Turns out #5 piston melted and #8 cracked a ring land. Block is no good for boost because I don't want to bore it. It can be bored to 0.20 over though. If anyone wants it for cheap, let me know. Here's #8 I can't swing replacing the block and building it so I think a Boss short block is in my future. Billet oil pump gears, ARP heads, cometic gaskets and boss valve springs. That and a fuel system. 600whp on pump and 800whp on ethanol and I should be good to go.
