  Here you go Jim...new cabin air intake, mostly for El Mirage dust problem. We'll tape it off for Bville and use
small air scoop on side window.

  Were ready to load car and truck next Sunday and head to Bville Wed; we checked and loaded our cases for
spare parts drills, bits, paper towels ect and loaded them into the rack in trailer.  Cleaned out the tune up tray
and removed duplicate tools from big tool chest. Also checked out aim on GoPro.
  All set except for surprise lettering for front lip

  Well, 222 took off, got a little sideways into 2nd and got loose in 4th for a bit started smoking on right side at the 31/4 and blew a #2 rod and windowed the block on both sides  at the 33/4. timed at 261 thru the 4th with chutes out a sec or 2 before end of 4. Data log shows 6571 rpm which is 290 mph. car was still accelerating even with #2 piston not sealing. Boost still going up to 34 lbs till it blew.

Data log shows at or near air fuel ratio target of 11.2 but plugs, except for #7 all look black even
#2 with part of the ground strap missing?

  Washed truck and car yesterday, trailer this morning.

  Wide tires still had little rubber mold sticks after 290 mph.

  Anyone know of a KB stage 8 block for sale

Some photos of our carnage from speed week.

There should be two push rods, you can see part of one.



A nice little hole in the manifold



Yep, that's one of the holes in the block.



This is the partial rod that escaped.



Even though we broke we still went above 290mph and we still have the tits on the tires.



And yes it is still the fastest Camaro in the world

That broken rod looks like a fatigue failure. Aluminum?

   machined forged billet top fuel .

  No beach marks as in fatigue failure.

  Learn more when engine comes out.

Oh yeah Aluminum  :-P

We have a KB without any windows. Not sure if its an 8. We replaced it with a billet block.  You can drive over and check it out in San Martin.

The tear down begins!!

Motor is out







Our first discovery



Then the next...





We decided to take the good cylinder head off first, for morale reasons.  Lol



Now the bad, better than we imagined...  Notice the bent head stud.



The missing rod.



The holes in the block, I can see day light through the block.





The Sleeve and piston...

Oh man, there is a lot of broken Subaru in there. Any idea what went first?

John and Troy,

Sorry to see all that damage to the engine. What stage KB block is that, VI, VII, or
VIII?  Hope you can find another block, as I know the Stage VI water blocks are pretty hard to find at this time, and I have read the new owners of KB are not making them at this time. All the best to getting things fixed.

    I think that the top of the rod failed first then the rest of the rod started swinging  around
causing parts to fly before it broke in two leaving big end still on crank spinning freely. top of piston is pushed out making me think that rest of rod gave it a final good bye. We have had a rod failure before with torching thru the piston to rod but no sign of that.

  Hunter at J@S garage says send him the block he's seen worse :-P

  Crankshaft looks fine.

                    JL222

  Just remembered. One or two of the other pistons rings were stuck as if detonation was pinching them.
  Data log shows AF ratio in low 11s and plugs looked way rich.
  Video of run shows smoke coming from right side . If oil rings were stuck some oil might not get
to wrist pin [oil holes to pin thru oil rings is an option tho]  and wrist pin is scuffed pretty bad.

A good thing you are using a centrifical blower, if it was a turbo you would be replacing it too.

Small graces.
