Did anyone else read in 5.0 magazine where the Ford Engineers told the author of the article that the 5.0 wouldn't be able to handle forced induction due to the connecting rods? It said that basically they were strong enough to handle the power it had, but any sort of major increase and they would have to be replaced. I searched as I figured this would be a large topic of discussion here, but I didn't see anything. Thoughts?

2011 5.0 connecting rods
It appears to be true that the powdered metal rods will not handle forced induction!
Can you believe FORD did this after all the bragging about how great & overbuilt this engine is!
They probably want to supercharge a 5.0 for the GT500 it'll have forged steel rods of course so they kicked the GT 5.0 down a notch!
Not happy about this at all with all the waiting i did to purchase the 2011 GT 5.0!This now may be a no sale situation!I'm now wondering how much expense it would be to install a good set of rods?I've also read elsewhere on the net that they (FORD) planned for the future (HP) with this engine allowing for mounting of a supercharger!What they seem to not know or just aren't telling us the rods would need to be replaced first.This stinks i was so ready to buy!I hope i used enough MAD smiles in this post!

Not only are the rod crap but the engine already starts at 11.0:1 compression ratio and doesn't have forged pistons...
I am pretty disappointed with Ford, and I was really happy until I heard the detailed engine specs.
So if you want that much power then just buy a GT500.

First off look at the power a stock 3v can handle and as for the 11:1 it's of no consequence the problem isn't boost it's detonation so if you add boost with a proper tune there will be no problem with the rods or the compression. You guys are stressing and the car isn't even the show rooms yet! Relax all the blower companies will sort that out, the forced induction industry isn't going to die.
THANKS

Thanks you sir 4 this post because your right i'm stressing about this!I'm so ready 2 buy!I can only watch & hope that you are correct!So again thanks 4 the reply it removed some of the stress i was feeling!I recieved a pretty vulgar uncivilized reply in another thread from nosmatt which was of course useless!

It would just be nice to have a strong starting point like with the terminators.

Not going to happen because they have to keep the car in a certain price range. They (Ford) knows there will be customers that want to increase power but not a very large percent will go blower route, I'ld say 80% will end up with CAI's and exhaust mods so they're not going to increase the cost of the car for an engine block they don't feel is required. FRPP does a lot of business with those Whipple kits that bring Ford in some extra income I'm sure they are testing boost limits and "safe" tunes as we post. I hope.

I completely agree with you. On another forum I saw a whipple engineer directly say they already have a kit testing and at the time was ahead of the 2010 camaro kit in progress towards production. I;ll be honest I am seriously considering the FRPP Whipple kit. I know some of the kits maintained the warranty but did the 550hp kit for the 05-10 maintain the warranty? I am hoping the new kits will have a 600hp and 650hp option.
Seems to me somebody has been sandbagging on the rod issue. If these rods are so weak why does the 2011 GT350 have a Whipple blower sitting on it? There is nothing in the specs of that car that states that Shelby will be replacing the stock rods in the 5.0 Coyote but they will be bolting an FRPP blower kit on top of it. I imagine it will only be pushing 5 or 6 PSI but it shouldn't take much to get a 412 hp NA motor into the 550 hp range.

No the 550HP Whipple kits do not maintain the warranty, in fact they don't have any warranty. As for other kits they don't maintain the cars warranty either, when they say warranty they mean on the blower itself as for big HP kits, perhaps some low HP kits will cover the engine but through Ford but through the blower manufacturer. As for 600HP possible, I hope so but I think they might stay the 550 output. I hope I'm wrong.
GREAT INFO!
This article & video from Motor Trend is the type of info i was looking 4!You'll note two big numbers are missing: horsepower and torque. The reason is simple. Much tuning and dyno work remains before final figures are released, but we can do some semi-educated noodling. It's reasonable, even with modest boost, to gain 25-35-percent more horsepower via a well-calibrated supercharger. Given the new 5.0's estimated 412-horse rating, that multiplier yields a guesstimated range of 515-556 horses.
The 5.0's compression ratio is a high 11.0:1. This suggests that, in order to produce a long-lived engine that Shelby is comfortable emissions-certifying and warranting, boost may need to be set at somewhat conservative levels.

THANKS 4 THE POST!powder metal rods
Actually the PM rods can be as strong or stronger the SAE 4340 forgings. It really depends on what the OEM manfacturer specs out. Here are a couple of intresting links.. One is on Metaldyne, who is on of the largest suppliers to OEM, the other is an aftermarket company who makes PM rods for specialty race engines.

The metaldyne article is referencing Diesel Con rods, but same point.
I would be real intrested in who makes the gt rods for Ford and there Mechanical Properties.
Who knows at 1.5 overall safety factor, That would put the limit around 600HP.
Its certainly not that simple, but with a 7k redline..one can only hope ford didnt skimp in this area.

WOW! Ford gives you a 100 more HP and you guys still find something to complain about!

sms reports 440 hp with a cai, pullies, and cat-back.
the rods are VERY strong. they are forged like gt500. consider them GT500 little brother. not as strong, but plent. the GT350 is rated for 500hp.
