Many of you know, the weekend before the Bash, I detonated the motor about two minutes after taking it off the dyno.  Well, I finally got a chance this weekend to tear into it.  Wow, I knew it threw rods out both sides of the block, but I certainly wasn't expecting this.  I've never seen a piston compltely disintegrate like this.  Some pretty amazing stuff.  I thought I would start this topic with the carniage first before the build.





Here's the remains of the piston in the pan:

Here's the new aluminator in the crate:

Wow, that was major ex/im-plosion.  Any idea what contributed to it?

The new block looks great.  Keep us updated.

I'm assuming you're doing this yourself?

Removing and re-installing the stuff from the old block to the new one always intimidated me.

[JeffJ]

Yes, I'll be doing it all myself.  We're still not sure of the cause.  I need to drop the tank and pull the pump.  I'm still somewhat concerned with the fuel pumps.  It may very well have been a lean condition.  However the stock rods are not very impressive on these, so may have been a bit too much boost also.  It shouldn't have been, but obviously something was too much!

Looks awesome .... can't wait for more updates.

Did you pick up a Oil Seperator yet?

Maybe a Whipple 550 would work better then a Paxton?

[H0050]

Wholy crap.  Look forward to the new build.

Cannot use the 550 with the auto, only the 475 whipple & tune.  Basically the non intercooled as I recall when I was looking at my options.

I didn't know that and but I do know he would never get rid of his Paxton since he paid Shelby to install it.

The 4.6 stock has hypereutectic pistons?

[SGT/SC#0471]

My guess would be too much boost heated up a Hypereutectic pistion where the top ring takes heat and then meltdown and you see the cunk missing from top ringland. Maybe with a bit of detonation to help it along.... Please keep us posted what the eventual cause is when you guys figure it out.

Interesting, sucks but not so bad congrats on the aluminator!!

[SGT/SC#0471]

Oops forgot the rods outside block!
Carnage!

[JeffJ]

Hoping to get the block pulled out tonight and drop the pan if I have time after work.  I'm really interested to see all the parts in there!

I was able to rule out one cause last night.  One tuner stated that he has seen one bad converter baloon which shoved the crank forward just enough to cause a fatal boom.  I had just installed the TCI street fighter converter so gave that a far out possibility.  When I removed the converter bolts last night, I was able to wiggle the converter in the flexplate just like it should.  So no preasure against the plate there from the converter.  So one possibility ruled out.

if you dont mind me asking and if you could pm me, what is the cost of an aluminator and what is the main differences between this and the "stock block"

[SGT/SC2873]

wow Jeff, sorry to hear but look forward to the build.  Craig

I short the aluminator is more geared toward Suprecharged applications

The stock block is M-6009-463V*http://www.fordracin...tKeyField=10405

• New production Mustang 4.6L 3 valve short block assembled in Ford Motor Company's Romeo Engine Plant
  
• Aluminum block with cast iron crankshaft
  
• Production connecting rods
  
• Production hypereutectic pistons
  
• Includes oil pump
  
• 9.8:1 compression with 3V 50.3cc cylinder heads

and the aluminator is M-6009-A463SC*http://www.fordracin...tkeyfield=10374

• Fits 2005-2010 Mustang GT
  
• Forged steel 8-bolt crankshaft
  
• Forged steel H-beam connecting rods
  
• Forged aluminum 16cc dish 3 valve pistons
  
• New oil pump
  
• Uses M-6010-A46NA block, knock sensor bosses are not removed from the block
  
• Approximately 8.7:1 compression ratio when used with 50.3cc 3 valve heads
  
• Lower compression for supercharged applications
  
• Built with all NEW PARTS
  
• Will accept 3V cylinder heads
  
• Will not work with 2V or 4V cylinder heads
  
• 8-bolt flywheel required (not included)

looks all too familiar........sorry to see your original motor go kaboom!
Will be following along......best of luck with the new build!

JPC racing had a real good deal on the Aluminator a few weeks ago for $3,200 shipped.  Amazing is the fact that it was delivered from Livoinia, MI the next day.  I ordered it Tuesday morning before the Bash, Yellow Freight called me on Wednesday while I was in line checking into the hotel in Vegas stating they had a delivery from Ford Racing.  That is service!

However I used this Aluminator, not the SC application with the lower compression.  JPC and others I've talked to, stated they only use this one.  The lower compression motor is really hard to drive on the street unless you are always building boost.  Too low of compression where it has little bottom end power until you get boost.  However with all the forged internals, this will hold far more power and boost than I will be putting to it.

Dang Jeff, you blew it up good and proper!

[JeffJ]

Here's the best picture yet.  Here's the contents of the oil pan.  Not sure what I was worried about, the piston was right there in the pan the entire time.  See, piston, rings, rod, it's all right there!
