WTF? they dyno a 2011 gt.

dyno vids are just now hitting you-tube

 

i have to disagree with the inside-line engineer. its a pre production example. but it still is what it is. a 395rwhp 5.0. who knows what tuning or cams it has.

if it is a loose factory car it has at least 438hp.

it could be a attempt to make headlines for themselves. hard to believe because the 5.0 is SAE certified like the LS-3.



i know if i get one i want those tuning parts.

 

Didn't someone just say it was done in 4th gear and they might of input the wrong gear ratio?

 

if these are real numbers corrected and everything the same numbers that all the 2011+ gt's will have, it will beat up on the new camaro in stock form.

 

Those are some big 'ifs' but I agree.

 

all of these "ifs" should get sorted out in a month or so, at least i hope.

 

that car might be pre-production but at this stage in the game with production starting in a couple weeks they are not going to have different cams in them. At best the tune might be different. Even if the dyno was happy figure 380rwhp to be the norm. 3500lbs and 380rwhp smokes 3900lbs and 380whp. I am sorry but the camaro is clearly at a loss here. The good news for camaro guys is that 5.0 is maxed out with 11:1:1 compression and factory shorty headers. The camaro has much more to gain from mods, A cam and headers and that gt will be needing a supercharger to to beat it.

 

I say good for FORD. It's about time they ponied up (no pun intended). There's nothing bad about adding power to a muscle car.

 

Yes, they did dyno in the wrong gear. Instead of 4th being 1:1 like most standard 6 speeds, 5th is 1:1 in that transmission. If they had dynoed it in 5th, it would have made less power as the motor would have been trying harder. I say have them redo it in the correct gear and get the correct numbers. Up until that point, I'm going to assume the numbers are inflated by approx 20HP (maybe more).

 

lol why get all excited from one loose dyno vid? we dont even know if those are the corrected numbers. I highly doubt the 5.0's will be putting 400 rwhp to the tires stock. 350-360 maybe

 

Yeah just wait for a correct production version test. We always see these pre-production tests that are super-high and everyone freaks out.

Looks like GM is really taking this new Mustang lineup seriously (i.e. upping power in the Camaro as a response)...this is great news for enthusiasts.

 

i cant see ford upping the power in the 5.0 as a response. they will make their cash for 5 or 6 years before doing anything else with it.

the powertrain boss has already said limited edition cars are for extra performance. ford will produce mach1's and bullitts and other cars for extra. the bean counters will make the money spent back first.

IMO.

 

Stout numbers.

 

Aren't they developing a 6.2L V8? What's that gonna make, anyone know?

 

the 6.2 makes 425hp/tq. but its a truck motor only for towing.

 

Well my 6L was also originally built for towing but it made quite a bit more afterwards.
Is the 6.2L design the same as the 5.0? If it is it would be safe to assume that people will be swapping it into a mustang no?

 

the 6.2 is a sohc 2 valve semi-hemi. it looks most like a 427sohc from 1965. it has 2 plugs.

the 6.2 liter boss heads flow about 330 stock and 370 ported. modular depot has been playing with some heads.

it ought to be very similar to a LS in powerband. i do know the 6.2boss peak hp is at 5500.

it is also easily enlarged to 7.5 liters. it has a 4.25" bore.

roush campaigned to first 7 liter and ran 9.10's @ 145mph with it. on motor. here is an article on the 7.0 liter boss.

In conjunction with Roush Engineering and Ford Motor Company, Don has fit an experimental engine under the hood of his Roush Stage 3 Mustang. The mysterious engine made its debut at the NMRA event at Milan Dragway (Milan, Michigan), and it performed admirably with a best of 9.10 at 145 mph. That was accomplished without the aid of a power adder and in less-than-stellar weather conditions. On-track performances were run at a race weight of 3,300 pounds, which puts output in the 800hp range.

Naturally, we went wild when we saw the new engine and how it performed. Unfortunately, Ford execs will say nothing-not a word or a peep other than that it's a V-8-even though we tried really hard to squeeze them for info. We've been shut down everywhere we turned for information on the mystery motor.


after some creative investigating, we uncovered what we think are rock-solid answers to the obvious questions. For starters, we're sure this engine is big. Our source in Detroit tells us it's 7.0 liters (about 427 ci), and it can go as big as 7.5 liters. We also hear it has favorable 4.250-inch bores, and from that we can calculate that the stroke is roughly 3.75 inches, offering nice revability. As for the heads, we hear the valves are laid out in a Hemi-style configuration.

2011 Mustang 5.0

3rd gear (1.69:1)
Horsepower: 365.26 hp @ 6600 rpm
Torque: 335.27 lb ft @ 4500 rpm

4th gear (1.32:1)
Horsepower: 377.99 hp @ 6500 rpm
Torque: 351.44 lb-ft @ 4400 rpm

SO how much is this thing making 365, 377, or 395 rwhp?

 

i would exclude the 395.

355-375 is what was expected to begin with.
