Tell me about it man I really looked after it to and did not drive it that hard at all. I did push it hard sometimes but barely ever hit the limiter and I never flogged the crap out of it. I've had cars that I have run the same oil for 30,000km's and flogged the living daylights out of them and had no issues.

I've heard a lot more stories about these new Ford V8's but unfortunately at the time when I bought mine none of the problems had arose yet till now. From speaking to other guys Ford 9 times out of 10 try to get out of the warranty work. The problem with the Boss 260 was the compression is too low like when the piston reaches TDC there is still 70thou of cylinder bore before the combustion chamber even starts. That's why all the FG XR8's run the higher comp boss 290.

So when I rebuilt It I had the block machined to get the comp up to the same spec as 290, bored, honed, bathed and new welch plugs, new crankshaft, bigger titanium pistons, acl race bearings, stronger rods, melling billet high flow oil pump, new valve stem seals, iridium plugs, 25% underdrive pulleys, throttle body spacer, blue power airbox with massive K&N pod its 10" long and 5" intake pipe, Billet products rip shifter, new stock clutch (Bad Decision), Difillipo 4-1 tuned length S/S headers 1 3/4" primaries into 3" with 3" S/S 200cpsi difillipo cats.
All up it cost me around $10k never added up the receipts and don't want to either. Just the gasket kit was $1200 lol.

Stock clutch was a bad choice though as the thing is making that much power now if you rev out 1st, 2nd then 3rd once you back off there's no clutch and while your flooring it especially 3rd you can just watch the clutch pedal fall towards the floor. Then you have to wait for the motor to spin down a bit and pump the clutch to get it to come back. You can just hit 4th sometimes but 3rd does 160 so that's enough.
Whats happening is the motor is spinning up way faster now than it use to and the inertia on the stock pressure plate causes it to lose pressure on the clutch. Its probably why I'm losing so much power to the wheels as the motor made 307kw and is only making 231kw at the wheels. Going to go with a Malwood option 3 clutch but at $1200 I'll wait till the stock one goes.
