I love reading comments on other sites.

They have no idea of gears, weight, power curve etc and they just continue to make stupid comments.
People have NO clue. Whatever helps them sleep at night.

 

You may be correct, but I can't confirm that

 

Ignorance is an epidemic. I would bet most of those sites also take stabs at the SLA because they have nothing else of worth to say.

 

Confirmed on Autoweek:

412hp @6500 rpm, 390 lb-ft.

Twin independent valve timing?! Tuned length headers?! What's the world comin to...

 

Yep, that's all the info I heard. Cat's outta the bag now.

 

 

Yeehaw! Giddyup, my little pony.

 

Is 412 really that impressive? I mean, Saleen already did it with the Parnelli Jones. BMW can squeeze 400hp out of a 4.4L V8 @ 5,500rpm, I don't think 412 @ 6500rpm is that impressive... I'm all for Ford products, but I expected 450 out of it, not that close to 400.

 

So, to sum up the Autoweek post:
-412hp/390tq @6500rpm
-tuned length headers
-all-aluminum block, cast iron sleeves
-4 blot main bearings
-25mpg
-forged steel crankshaft
-wide distance between heads allows intake ports to sit vertically on engine

 

5.0L may be bigger than 4.6L, but it is still a relatively small engine by V8 standards. I imagine that it is an oversquare configuration (bore is bigger than stroke), so it is designed more for revs and hp. Undersquare (longer stroke than bore) would yield bigger torque numbers, but yield smaller hp #'s - and we all know that hp sells cars (even though torque "supposedly" wins drag races).

So, I would not be surprised to see 412hp & 380tq for this new 5.0L. Dang, that's very close to my supercharged 07 GT (~455hp / ~380tq at the flywheel). Guess I need to mod just a little more to put some distance on the '11 GT's...

 

Wow, someone couldn't keep their traps shut.

 

Yeah, it's only 10 days early.

 

Christmas has come early guys!

 

My guess is the compression ratio on this motor is lower than the M3's (4.0 liter) 414hp engine (only 295 lb-ft), to allow a FRPP supercharger without changing the pistons. Higher compression ratio always gives a higher specific output, usually at higher revs, and BMWs mills are known for that. I also think the M3 and M5 V8/V10 use individual throttles for each cylinder, correct? Though now Ford has a double variable camshaft timing too...

 

Sounds **** good to me. Besides, I'm sure it's capable of a LOT more. Why blow your wad right out of the gate if you don't have to?

 

Exactly..

Goodbye '03 hello '11 :-)

 

Where's that peak torque reached at RPM wise?
I'm hoping below 5k...

 

I really think it is impressive when you compare it to an M3. You have an engine that makes 2 less peak HP but nearly 100 more lb-ft of TQ, all in overall package that gets 20% better fuel economy and costs $20K-$25K less.

 

Autoweek
"To Ford Mustang fans, 5.0 means a lot, and the new 2011 5.0-liter V8 Mustang will deliver 412 hp and 390 lb-ft of torque, company officials said on Thursday. The information was supposed to be embargoed until Dec. 28, but news leaked out shortly after the announcement in Dearborn, Mich.

The new 5.0-liter Mustang produces 83 hp per liter yet will return 25 mpg, according to Ford marketing boss Jim Farley. The 5.0-liter Mustang’s main competitors are the Chevrolet Camaro SS, rated at 426 hp, and the Dodge Challenger SRT8, which makes 425 hp. Of course, the top-of-the-line Shelby GT500 and its supercharged V8 is rated at 540 hp.

What makes the brand-new V8 engine powering the ’Stang so potent is how engineers were able to allow the engine to breathe. All-new heads sit atop an all-new aluminum block with cast-iron cylinder sleeves. The wide distance between the heads allows for the intake ports to sit vertically on top of the engine. The engine features four valves per cylinder and twin independent variable valve timing. Tuned exhaust headers eliminate the need for aftermarket headers to let the engine breath better. Inside the engine are a forged-steel full counterweight crankshaft and four-bolt main bearings and high-performance pistons and connecting rods. Peak horsepower is reached at 6,500 rpm.

The new 5.0-liter Mustangs can be fitted with either the 6R80 automatic transmission or the MT82 six-speed manual.

The pony car will make its official debut at the Detroit auto show in January."

So I am glad that we have a forged steel crankshaft but when they say perfformance pistons and rods does that also mean forged as well? I don't want to worry about blowing out the engine when adding a sc to the already potent 5.0

So what they are saying is that going aftermarket with headers will not yield that much of a gain or what? Will there even be a need to replace them except for changing the sound?
