Recently we've had the question come up a couple of times of whether or not upgraded rods and pistons are necessary for the 3.5L Ecoboost, here are a couple of photos of an engine that was sent to us for upgrading after suffering a failure. This was a rather high output engine with tune, turbos, etc. As the pictures show, there is a power limit to what the stock parts will handle before failure.

From examining the pistons, rings and bearings there are no signs of this failure being related to detonation or fuel. At power levels above 400WHP you start to get into a territory where the parts are near their outer limits, Beyond 450WHP you get into the territory where it's just a matter of when, not if, the stock rods and pistons will have a failure, because of this a piston and rod upgrade become practically a necessity in order to avoid eventual catastrophic engine failure. Again, while you could probably get away with running the stock bottom end near the 450WHP level, it's only a matter of time before the parts will catastrophically fail.

Below is some information on our Ecoboost piston and rod upgrade. We also offer an Ecoboost head stud kit as well that replaces the factory bolts with upgraded studs. This stud kit allows for greater clamping force to keep the cylinder heads in place under high loads typical of modified Ecoboost engines.

Do you guys sell short blocks with these upgrades?

Livernois Motorsports

Yes we could defintely set you up with an estimate to have one built if you would like.

Cord

Rod broke in two places, both skirts gone and piston broke through the pin. What actually let go first? I'm thinking skirt so the piston got jammed in sideways causing other parts to fail.

What turbos were in the truck?

Joewee3.5

Didn't Mike B have 600 whp on stock internals? If you say they are only good to 450 then his rods should have snapped like a match stock as soon as he pressed the gas.

StrawHatShinobi

Mike did have stock internals and I've been running my setup for just about a year and 12k+ miles making 480+ HP so I think there's some room yet.

FlameBlueFX4

Sure did, and wouldn't that be like 725-750HP at the crank?

Where is that new HPFP???

Sounds like from what y'all are saying someone is fear mongering, I hate companies that say one thing when they are selling a certain product and turn around and say something else when they are selling something else.
