Anyone See A Problem??

Done!!

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

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

Are you retuning the car?

[Marauderjack]

Yes Marty.....

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

[Marauderjack]

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

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

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

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.

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

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

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

[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??

Not sure how this is done during mfg.

Then swapping the injectors should not be an issue!!
