Max torque would likely be 400 ft pounds at 4k or so.

HP..not so high...
Trq..not so low...

Here are my predictions for the 2011 Mustang GT:

MSRP: $28,999 (base)
Horsepower: 400 @ 6500 rpm
Torque: 375 @ 4500 rpm
Weight: 3650 lb
0-60 mph: 4.6 sec
1/4-mile: 12.9 sec @ 110 mph
60-0 mph: 110 ft
Skidpad: .95g
Slalom: 70 mph

Predictions are based on a well-equipped Mustang GT used by typical car magazines such as Car and Driver. Consumer Reports will produce more conservative performance results.

I was talking about torque @ 6800 RPM.

Since these are all wild-*** guesses anyway why not use the logic that if The Insider claimed 315 for the 3.7L and it came in at 305 then the 5.0L will probably come in at 390 hp.

Falc'man

There's more than one insider.

Boomer

Mine was more aimed at rated numbers.

Not necessarily.
Numbers are close. What could happen is that what the engine CAN do, and what they decide to rate it at or final tune it, as well as what it makes on paper VS what it makes in final trim are not the same.

So just because one person says 'x' number doesn't mean it didn't make it at one time, was considered, or does make just not on paper.
It's not like they said 'it makes 350' and it makes 300...

Overboost

I agree Boomer. There are probably a few people on here who have some sort of connections to legitimate contacts who might know something, but during the process, things can change. I'm hoping to have more concrete info by the end of the week from one of my sources.

GM guys would snicker, but 390hp would still put a hurting on the current SS (by a margin of about 30hp IIRC), Although 430hp might be plausible using the V6 as a yardstick, it just edeges out the F5 LT's output, I could see Ford using the same gimmick with the V8.

Clino

I am thinking that just for the sake of how it looks on paper, Ford will rate the 5.0 at at least 400hp if not a touch over (I think it will be mildly under-rated as well).

For example if the V6 is rated at 305hp and the GT is rated at 390hp...it just doesn't give that sense of the GT being in a different league, ya know? But the ring of 400 or 410hp for the GT just looks better on paper and although the difference is minimal, would be perceived as being more desirable IMO.

Also, let's be honest, the history and reputation attached to this particular displacement demands something that will live up to it.

Lastly, whenever I get nervous about the future of Ford performance, I just think of one word...Raptor. The fact that Ford made such an excesive vehicle, that is so catered to, and in tune with the enthusiast shows how serious they are these days. I have all the faith in the world right now.

eci

I've owned 3 5.0 foxes... the rep comes from cheap power and modability. I don't think aftermarket heads/cams/intake options for this new technological terror will be cheap.

Overboost

I like the way that sounds.

Five Oh Brian

Umm, the old 5.0L made a meager 157-245 hp, depending upon year and application. Even the most popular 5.0L's ('87-'93 Fox Bodies) made just 225hp (or 215hp, depending on who you believe). There would have been no history or reputation w/o the aftermarket (as ECI pointed out).

Don't get me wrong, I love the old 5.0L (hence my user name). I owned several of them. However, the 4.6L's (especially the 3V and 4V) easily outgunned the 5.0L's. The new 5.0L doesn't have to make 400+ hp to be worthy of a spot in Mustang lore & history, IMO. 350+ hp would be more than enough. 400+ hp would be great, but not necessary. Save the bigger hp #'s for special editions, and keep the GT model cheap so that most of us can afford them!

Clino

Although I understand what you're saying, I have to disagree.

Although there have been many quicker and more powerful Mustangs since the 5.0s, there is still a repuation attached to that motor that exceeds it's actual performance. As well, it's not what it does in comparison to todays standards, but more to do with what it did back when it was current. There were few common cars that were quicker at the time. Even one's much more expensive. Of course there are now family sedans that will outrun a stock 5.0...that's not the point.

That's like saying that there is no reputation attched to a vintage Cobra Jet or a Boss 302 because the current Mustangs that are quicker or that can outperform them.

Before the 3.7 came out, i would have agreed with you on the 350hp being enough, but now with the base motor making 305...no way. The GT should stay cheap, and i think it will, but it has to offer a significant amount of performance over the base model to justify the price difference. 350hp wouldn't do that I don't think...V8 sound or not.

RedCandy5.0

I can not see Ford staying under 400. They know 400 sounds way better than 390. Plus with the SS over 400 and im sure the R/T will be 400+ now that the STR8 will be getting a boost. To many sources saying between 400-425. With the economy, competition ect they need to stay competitive.

1trickpony

I think 410 HP and 375 TQ are in the ballpark and consistent with the 3.7L. As far as I can tell the 5.0 and the 3.7 share the same technology so outputs per liter should be similar. If anything, you'd think the 5.0 would be cammed for higher peak outputs campared to the V6.

SpOnkey21

TIVVT will help the low end torque, too. I don't see there being a big difference between the tq and hp figures. It may feature similar tech to the 3.7, but it also has two more cylinders, which will change the way the curves are shaped to some extent. More cylinders usually means more tq, and the addition of TIVVT will only make it easier to have your cake (high hp numbers in upper rpms) and eat it too (strong tq in the lower rpms). Nowadays you can actually tune a car to have both. If the HP is at 400 (which seams reasonable), I'd say the TQ will also be around 400 as well. Just my opinion.

blksn8k

I just hope there is not a lot of *****ing and moaning if the 5.0 doesn't come in at 400 or more. After all, none of these numbers that are being thrown around are coming from Ford...RIGHT?

karman

No, Ford has hinted at the 400 number a lot.

YSUsteven

All I want is 350+ HP (which is gauarenteed at this point), and I am going to throw 390 HP and 370 Tq. out there as my guess with a 6,500 red line. If the rumor still remains that the 5.0 will get a power boost in 2012, that is when I think it will move north of 400 and possibly to 7,000.

Hopefully I will know how far off my guess is in less than 1 month...
