I just received a call today from the machine shop saying that my parts are ready. We will reassembly the engine next weekend. Also we are looking to buy a water/meth kit.

He had problems on the dyno and waiting for the crank to be done. A bolt from the oil pump came off and I think blocked the oil from getting in there. So no track times yet.

ooo that sounds like he might need to get his turbo repaired if the oil pump failed!

Damn. I figured the 476whp numbers were solid with no problems. So, he had problems when the 476 was done. Good numbers by the way.

From page 20...

You can see the nut inside the pickup tube here.....


This confirms what I said before opening the engine. The problem was caused by lubrication failure but not because of the higher rev limit as it was caused by the oil pump failing to work because of the nut that is supposed to hold it.

The sad part is the crankshaft is damaged but salvageable and the K1 connecting rods are OK. We will keep you guys informed of the next step as sonn as we decide what to do. We might resize the cranksahft or install a new one. We will see....

The engine had low oil pressure and was shut down before the oil pressure dropped to zero.
Additionally we have a Peterson fluids oil filter before the turbo in case something like this happened! It has a 60 micron filter element and can be cleaned or replaced.

Few more questions for Pito or any one with the knowledge...

is the RPM signal that the TC outputs "5volt DIGITAL"?
or is it an ANALOG signal?

also is the "throttle position sensor a switching-type?

props to one of the most helpful threads on SL!!

I have to check that on my notes as I don't remember

Nope. The TPS outputs a linear rising voltage that goes from 0 to 5v!!

What did you guys do to install the ARP head studs? Does it need to be taken to a machine shop to make the holes bigger or can it be done with a drill press?

The ARP head bolts are a direct fit to the engine. You don't need to modify anything to install them: just hand tight them in the block and use the supplied moly lube on the nut!

According to the FSM the TACH wire on the tC outputs a 12v digital signal!
This is true for 2005-2007!

All the piping (from the intake to I/C pipes and all the exhaust) is custom made. The fabricator uses 90 degree mandrel bends and cuts and welds them according to the shape he wants to make!

The Intake pipe is 4" in diameter. The I/C pipes are 3" and also all the exhaust is 3".
