340-350rwhp. too bad the interior on 05+ sucks. the parking brake sits on my right leg, and there is no place to rest the right leg on a long drive. the plastic bites into my leg. too bad.
The basic parameters were laid out as such: 5.0 liters of displacement and 400 horsepower. The end result is an engine with 92.2mm bore and a 92.7mm stroke. For the mathematically challenged, that works out to 4,952 cubic centimeters and now properly rounds to 5.0-liters while still equaling 302.2 cubic inches. As for the power requirement? Mission accomplished, with 412 hp at 6,500 rpm and 390 pound-feet at 4,000 rpm.
The new 5.0 also has a brand new aluminum cylinder block and heads designed to maximize performance while keeping weight down.The result is a block that's heavily ribbed for rigidity and a deep crank-case that extends down to the bottom of the crankshaft. The 5.0 has four-bolt main bearing caps and the deep crank-case allows the side bolts to fit through the wall into caps that add extra rigidity and support. The configuration happens to be similar to that used on General Motors' LS9 and LSA engines in the ZR1 and CTS-V. Cast-iron cylinder liners, meanwhile, are pressed into the aluminum block to insure a good wearing surface.
The crankshaft is made of forged steel and is fully counter-weighted to aid smoothness. The connecting rods are forged powdered metal and the pistons are hyper-eutectic
Even without using direct injection, Ford was still able to achieve an impressive 11:1 compression ratio while allowing the engine to still run on regular gas. According to Harrison, a lot of effort was expended on the engine management system. The adaptive spark control system keeps the engine running right on the knock sensor all the time, continuously adjusting the spark advance to avoid detonation regardless of the fuel used. The control system has a high bandwidth air-fuel control algorithm to make sure that it's both responsive and efficient. The 5.0 has also benefited from work done on the Fusion Hybrid by incorporating aggressive deceleration fuel shut-off. Whenever the throttle is released, fuel flow is shut off completely to improve efficiency.
Once the fuel is burned, it's just as important to get the exhaust gases out of the engine as it is to get air in. With this in mind, the 5.0 has tubular stainless steel exhaust headers. The design of the headers features two secondary tubes that flow into two primary tubes, which then flow into a common collector. The tube lengths are tuned to ensure that there are no exhaust pulses pushing gases back into adjacent cylinders. Engineer Adam Christian developed the headers using a CFD program, but when the design was sent out to a local prototype shop for fabrication, the parts performed poorly on the dyno. After seeing the results, Christian requisitioned some tubing, took it home and fabricated a set of headers using his own tools. These performed perfectly on the engine and were used to correlate the model. The production units are being supplied to Ford by Benteler Automotive.
While torque peaks at 4,000 rpm, it's well above 300 pound-feet throughout most of the rpm range. The redline of the 5.0 has also been moved up an extra 500 rpm compared to the prior 4.6-liter to a full 7,000 rpm, and judging by the curves we were shown, it will probably be worth using all of them. Thanks in part to the higher compression, the engine is also more efficient than the 4.6-liter V8. In spite of producing 31 percent more power and 20 percent more torque than the old 4.6, the new engine achieves four-five percent better efficiency across its operating range. As such, the 2011 Mustang GT is expected to score at least 25 mpg on the highway from the EPA.
I'll take a white one, no options, with the street scene bumper:
Edit: Actually, i'd end up painting it in the future, so we'll start off black.
my budget is $42,000.00 surely i can get a nice one for that.
The gt is going to be expensive. Prob going to be upper 30s easily
