Slight bend.

A little work with a BFH and vise and you'll be good to go! :D

That must have been some really bad gas, Jack!

[Marauderjack]

I am at a loss......

THREE BROKEN RING LANDS and a BENT ROD now......LUCKY it didn't go.......BOOM!! :cool:

BTW.....the gas station gave me a report on the gas the day I bought it......the delivery that day was 93.1 Octane!!:(

Do injectors just go bad or did the fuel pump just die....WHAT ELSE COULD IT BE??:confused:

[Motorhead350]

What was the station?

WHAT ELSE COULD IT BE??:confused:

A boosted extremely high mileage application being run hard in cold air.

Further affiant sayeth naught.

Precisely!!!

Has your builder checked the fuel system before installing the new motah?

Ohhh, mine has moderate miles, but I never realized cold air caused risk with boost, my simple thought was colder IAT = no hot charge to detonate.
I'll learn more tomorrow too....

Parker's Convenience Stores out of Savannah opened a nice new store.....filled up once then the problem!!:( All records and the SC Authorities say it was 93 octane!!:cool:

Fuels system upgraded.......new pump......new filter!!:beer:

Also has rear cooling mod!!:D

Anything can go wrong for a split second and result in catastrophic failure.

Just think about what goes on inside an Internal COMBUSTION Engine that is turning at 5,000+ revs per minute.

Injectors are like light bulbs.

As you know finding the "cause" is crucial or it will repeat.

I would definitely swap injectors or have them bench tested/flow matched at that high of mileage.

I'll double the money and concur with you. Now we are up to four cents.

Done!!:beer:

Problem now is FORD Racing 39# injectors are back ordered until March!!:mad2: Will 42# injectors work OK or will they be too rich (big)??:confused:

Check these '04 Mustang rods he has...YIKES!!:eek:

Are you retuning the car?

[Marauderjack]

Yes Marty.....

It has Diablo Tuning and Steve, like most of you guys, uses SCT tuning!!:beer:

[Marauderjack]

BTW, has anyone seen the "parting line" on the BIG END of the OEM "sintered metal" rods???:eek: :depress:

It looks like they break the damn things!!:shake: It's cinch ya couldn't mix the caps up!!:rolleyes:

Had I seen this before I probably would NOT have Supercharged an OEM motor!!:(

[RubberCtyRauder]

sintered rods are used for production because they are dense, lightweight and are very stable after the sinterizing furnace, meaning very little secondary machine work..old cast rods required much more machine work and were subject to porosity depending on the casting process.

[Marauderjack]

I understand the technology completely......just never imagined the would literally "BREAK" the big end of the rods to separate the halves!!:eek:

After talking to several people I understand FORD has done this quite awhile!!:confused:

How is the "BREAK" actually done and how do they make it break exactly in the center??:cool:

[RubberCtyRauder]

I would have to see a pic to see what you are talking about. Stamped metal parts that are punched out have a cut band and a break band..it is not punched all the way. Die cast items are overfilled to reduce porosity into overflow pockets and these are trimmed away in a trim die which cuts and breaks the edge/perimeter off.

I don't know technically how it's done, but I do remember the news reports out of Ford when it started, and you are correct, they actually break them to get that rough finish for a perfect fit. No misalignment with these, which is the reason they do it.

Here are 3 photos of one of the roughest ones I have......some are fairly smooth but at an angle......looks kind CRUDE to me but it must work??:eek::shake:

[RubberCtyRauder]

Not sure how this is done during mfg.

[martyo]

Then swapping the injectors should not be an issue!!
