This motor is running at 440 hp FROM THE FACTORY and you guys are pissing and moaning about not being able to extract more power from the car because you don't want to pay to play?

On my 4.6 I had to spend upwards of 5 grand to get my car where your car is FROM THE FACTORY!

Ford produced an incredible engine with a CR of 11:1 because they wanted to give Mustang enthusiasts a badass Mustang that was faster than ANY OTHER CAR at its price point.

People will complain no matter what I guess.

Look at it this way... if Ford had produced the 5.0 with a 9:1 CR and more room to mod then it would have probably rated more toward 350hp or so depending (I'm totally guessing) and then you would HAVE to buy a blower to get it BACK up to 440hp. So you would have to pay upwards of 3-5k with fuel pumps, blower, tune, etc.

Would you be happy then?

I agree a tune and CAI is a "minor" mod for sure. But minor I suppose is a relative term when talking about different motors.

It seems to me that this particular 5.0 motor is close to its limit already and maybe that's why people are having issues.

I agree that Ford probably should have engineered more wiggle room in the motor for cases like these, but it is what it is.

You want to go to Chevy... go for it. I'm sure they'll pay for you to mod your car and then blow it up....or not?

 

440? Are talking BOSS? Us GT owners only have a measly 412.

 

Yeah 440 is the Boss motor. And besides, the boss is all forged internals so we know it won't drop #8.

 

this cannot be said enough....everyone who has ANY contact @ dealerships, tuners who have heard of stock failures ect should be beating the bushes trying to find un-tuned cars with this problem and getting as much info about them as possible. If it can be shown that stock cars have this problem, even not as frequent as tuned cars the entire issue then becomes a position for ford they have to defend, not the guys with the tuned cars.

 

Oh yes sorry... a measly 412

 

True forged? Or forged powdered metal and hypereutectic pistons?


And some have complained about ring spacing. Is the ring spacing the same in the Boss engine as the GT?

And didn't they remove the piston squirters on the Boss?

 

Sounds to me like he manned up. And isn't just another American crook trying to steal from others for his own error/risk taking.

Respect.

 

+1. Agreed. Like everyone else in this country.

 

According to the August issue of 5.0 magazine (has a whole article on the BOSS engine), the pistons are Mahle forged pistons, and the rods are upgraded powdered rods. The crank is also upgraded slightly, but not much since the GT crank is forged as well. So the rods aren't fully forged, but the pistons are. And yes, the squirters are removed in the boss application, but this is because of the pistons. The GT pistons depend on those squirters to keep them cool enough not to come apart.

They have a TSB on this failure... They'll find out the car is tuned and they'll just tell me to eff off. It's 150 to plug in their check engine diagnostic alone and who knows how much for everything else... And no im not " rolling like that" either. They aren't going to fix it and it has nothing to do with my TR6060, they wouldn't even notice it.

I'm actually off of work today. You guys want me to take it in to the Ford dealership? Tune it to stock and unplug the battery... Just to prove to you that they aren't going to warranty it. I do believe that they should prove it was the tune but they aren't because of that TSB.
How much would they charge me for a compression test if they did that?

Thanks guys...

 

Totally opposite. A tune is not going fry the #8 cylinder each and every time there is a failure. If it was randomly #1-8 , then I would say ok folks this engine can not handle a tune. This motor was designed to handle future forced induction by Ford etc. When the stock cars pile up with #8 cylinder problems, is when **** will hit the fan. I don't want anything for free, just fairness to customers . No different than your Prius getting 20 MPG.

 

Says who... at 11.1?

Sounds to me like Ford was wanting to get the most out of NA. That some are using mild boost is their own experiment.

 

It looks like you will not see anymore aggressive tunes from tuners. Most tunes will be pretty even across the board now. They are all keeping a/f 12.1-12.4 or Air Fuel its commanded Widebands will target and correct to +-1% of target which is .84 lambda. Spark will be Safe. KS will be stock.

 

You don't want anything for free but you want to mod your car and have Ford fix it when it blows?

How is that not wanting anything for free?

I'm sure they will replace a motor for someone that is running a stock car and the #8 piston goes. But under your reasoning they should include you as well... just because it's not "fair" to not include you?

BTW a Prius gets much more than 20 mpg I'm pretty sure... I'd love to race your 2011 in my "Prius"

Also I agree with the above statement by cdynaco... a motor with an 11:1 CR is NOT setup for boost.

 

This is the first Mustang of the 4 I've owned that I haven't modded. Partially because the car seems plenty fast enough as is but now I'm worried about popping an engine. Guess I could go with AM and their warrantee coverage. But since this is my daily driver I really couldn't afford to have any down time. I'm going to watch and wait until this all gets sorted.

 

As a Corvette owner I can assure you that GM will NOT cover your car if it blows and it is tuned. GM is very strict on covering cars that are tuned. That is why my car is staying 100% stock. Ford isn't doing any thing different than the other manufacturers are in protecting themselves.

 

Same with Chrysler. A race shop I deal with said they are so **** that I should remove my oil sep before taking it to the Dealer.

 

A hell of a lot more than it would cost you to go to a parts store, buy one and do it yourself.
