Wondering how strong your stock rods are?
I have been telling people for awhile about the toobrush pic my friend Paul took when he tore down his motor to illustrate just how crappy the stock rods are in the car.
I finally found it and wanted to show you to make my point that even with the best tune on the planet, it is a crapshoot over 450 rwhp with these rods. No amount of tuning makes these things any stronger or bigger than they are so take it for what it's worth...

Ditto - it's all about money and mass production. Same reason we have phnuematic pistons.
I just wanted a reference for you to see when you hear about how 'with a good tune' you can.. blah blah blah...
Tuning is essential and the most important thing - no doubt, but you should always keep this pic in mind when you are questing for power from your tuner. When Diablosport and SCT have a tune function that doubles these things in size, then you can shoot for the moon with em'...

RE: Wondering how strong your stock rods are?
what does the toothbrush signify? what am i not seeing in the pic?
ohh is it that the rod is really thin or something?
its a crappy little ibeam what do u expect from ford.
btw its hypereuctic i think or something like that. its stronger than casting.

OH MY ****ING GOD [:'(]
My guess on why - besides cost, would be weight. The lighter you can get the rotating assembly thebetter your mileagewill be. Good old CAFE standards. I still think it's a joke though. That is beyond scary.
FFB - I just saved the pic on my 'puter so I can show it to all of the "I've been making 580rwhp for 2 years with no probs - it's all tuning" guys LOL

Mark,
no doubt its not a meaty piece of metal... I think what also need to underderstood is that these rods are "powedered" in there manufacuturing and not forged so they metallurgy is also weak. certainly if they rods were made from titanium and the same dimensions they'd handle a heck of a lot more power!

RE: Wondering how strong your stock rods are?
While I am not going to argue that our rods are about as skinny as a super model on Jenny Craig, I think the whole point that people try to make about the tune is, that a good tune can lessen the stresses put on the rods.
Am I saying that a good tune will let these things stand up to 500+ RWHP and be fine? Hell no. But a good tune will let them stand up to 460 RWHP and live a good life to talk about it, whereas a mediocre tune and 435 RWHP would make them into paperweights faster then you can blink.
And as faras Fords perspective... Less mass = less parasitic losses on the motor = more HP at the crank. The motor does not rev particularly high, so not alot of stress there to beat either. Seriously, if 1/2 of 1% of all the Mustang GT's that Ford makes with the 3 valve 4.6 liter Mod motor sees enough horsepower to eat a rod, I would call that a miracle. Remember, that most of us that are here on these forums are the exception on what we expect from a vehicle, not the rule.
