What has 360hp, 650lb.-ft., 20psi boost stock?

[Ekliptix]

We've got to wait while for the programmer he wants to be available for this engine.
From what I've read the Edge one are the best:

Cool stuff, Theres a guy down in NS that I've seen around a few times, hes chipped, and propane injection (I think)...etc.. pushin over 700hp.. When he sits on the line and starts stepping up the revs the black smoke out of that thing is unreal and so is it's grunt.. He's always racing it, sand draggin, truck pulls..etc.. It's his daily driver... I honestly don't know his entire setup, but my buddy who has raced him says he's seen him a few times pushing a little button on a screen on the dash while racing, whatever that is...

[luderollup]

that is an amazing truck.. my toolpush for trailblazer had a 2005 duramax and it was pushing 1100 HP and over 2000 Torque...

chipped, methanol-water, propane injection, intake, big ass exhaust, NOS, he put over 40 grand into the transmission and powertrain...


truck was so fast he could light up all 4 wheels for as long as he wanted... personally saw him kill a supercharged mustang cobra


personally i still like the 1500HD the most, my pops had a 2004 1500Hd with Vortech supercharger and a bunch of other mods and he was pushing almost 600hp to the wheels

Was just going to say my Thunderbird

Nice truck You drop out of SAIT? I don't see you anymore

[b_t]

Just drove one of these today and I fuckin love it, so ballsy I melted in my seat. That was a lot of torque! I could definitely get used to driving one of those.

lol buddy, good math skills

Nah, just joking. But we know as soon as you hop in the trailer, it can't do it

It's a giant freaking trailer, though. I just find it pretty amazing that the Chevy could theoretically pull it, and it's not even a duallie. My dad had to get someone else to move it for us; his F150 didn't have a hope in heck of moving that beast!

[CelicaST-162]

Banks six gun tuner! Six power settings!

[EK 2.0]

Nice Chev ya got there Son!!

[Kirbs17]

nice truck

[ninspeed]

ahhh.. but no 6 speed auto ....

[Ekliptix]

yes, it has a 6 speed auto. With electric manual shifting.

Hey, I think that towing capacity I quoted is for the dually.

Here's some info:
The Duramax 6600’s horsepower and torque increase and emissions reduction are enabled by a strengthened iron cylinder block and a lower compression ratio. The lower compression reduces stress on the engine by reducing the peak cylinder firing pressure. This, in turn, allows more fuel to be burned – more fuel means more power – while the lower compression helps reduce NOx emissions. Lower compression also helps reduce noise and vibration, making the all variants of the 6600 a quieter and smoother engine.

A revised variable-geometry turbocharger also enhances the driving experience of the Duramax 6600. Aerodynamic changes to the turbo’s vanes help tailor controlled application of turbo power for seamless and immediate response at full throttle. The turbo, which spins at up to 120,000 rpm, is high-speed-balanced, reducing vibration and resonance – and contributing to the engine’s overall smoothness and refinement. The revised turbo also helps reduce emissions, while maximum boost remains at 20 psi.

Another new feature of the Duramax 6600’s turbo system is the capability of the variable-geometry turbocharger to provide exhaust braking. This function is available on some medium-duty truck models and can replace add-on exhaust brake hardware. With the new system, braking is controlled by a signal from the engine controller and can be activated by the driver.

The comprehensive list of changes and upgrades to the 2006 Duramax 6600 includes:

* Cylinder block casting and machining changes strengthen the bottom of the cylinder bores to support increased horsepower and torque
* Upgraded main bearing material increases durability
* Revised piston design helps lower compression ratio to 16.8:1 from 17.5:1
* Piston pin bore diameter increased for increased strength
* Connecting rod “ I ” section is thicker for increased strength
* Cylinder heads revised to accommodate lower compression and reduced cylinder firing pressure
* Maximum injection pressure increased from 23,000 psi to more than 26,000 psi
* Fuel delivered via higher-pressure pump, fuel rails, distribution lines and all-new, seven-hole fuel injectors

* Fuel injectors spray directly onto glow plugs, providing faster, better-quality starts and more complete cold-start combustion for reduced emissions
* Improved glow plugs heat up faster through an independent controller
* Revised variable-geometry turbocharger is aerodynamically more efficient to help deliver smooth and immediate response and lower emissions
* Air induction system re-tuned to enhance quietness
* EGR has larger cooler to bring more exhaust into the system
* First application of new, 32-bit E35 controller, which adjusts and compensates for the fuel flow to bolster efficiency and reduce emissions

The Duramax 6600 also has a new intake air heater to reduce smoke and emissions during cold or light-load driving. The system features a 1000-watt grid heater located in the air intake duct, which is triggered automatically by the engine controller. It heats up the incoming air to speed warm-up of the engine.

In addition to 50 more horsepower and 45 more lb-ft of torque in the Silverado and Sierra, changes to the 2006 Duramax 6600 build on a host of improvements introduced for ’05 – improvements that bolstered an already strong foundation. The Duramax 6600 features a rigid cast iron cylinder block with induction-hardened cylinder bores; four-bolt, cross-drilled main bearing caps; forged steel, nitride-hardened crankshaft; aluminum pistons with jet-spray oil cooling; aluminum cylinder heads with four valves per cylinder; integrated oil cooler and a charge-cooled turbocharging system. Features, such as easy-access fuel filter and timing gears, reduce maintenance time and effort.

A new, 32-bit E35 engine controller monitors and adjusts the engine’s operation. Designed exclusively for the Duramax diesel engine, the controller helps the injectors precisely meter fuel to the cylinders and can compensate for the variability of the injectors and fuel flow. This sophisticated, more powerful controller also can support up to five injections per cylinder and eliminates the need for an engine-mounted drive unit to fire the fuel injectors.

The new Duramax 6600 in the Silverado and Sierra heavy-duty pick-ups will be available exclusively with the new Allison 1000 6-speed automatic transmission, featuring class-first features, like tap-shift range selection mode.


The Allison 1000 transmission grows from a five-speed automatic to a first-in-class six-speed automatic for the 2006 Chevrolet Silverado HD and GMC Sierra HD trucks equipped with the Duramax 6600 6.6L V-8 diesel or Vortec 8100 8.1L V-8. Also new for 2006, the Allison 1000 six-speed features a class-first tap-shift range selection function, as well as offering enhanced fuel mileage, quietness and control. The range selection function allows the driver to easily select the desired gears to match driving conditions, such as towing a trailer on a steep grade.

“Changes to the Allison 1000 represent a ‘best of all worlds’ scenario,” said Kevin Wayman, Allison 1000 chief engineer. “Performance, quietness and fuel mileage are all enhanced without degradation to product durability.”

The sixth gear – essentially a second overdrive gear – enables a wide, 5.08:1 overall forward gear ratio coverage and allows the vehicle’s engine to operate at lower rpm, particularly during higher-speed driving on highways and freeways. Its 0.61 ratio sixth gear provides a 1550-rpm engine speed at 60 mph, compared with the five-speed transmission’s 1800-rpm engine speed at 60 mph. The engine uses less fuel at lower rpm, enabling increased fuel mileage and range. The ratios of gears 1 through 5 remain the same as the Allison 1000 five-speed, including the 0.71:1 fifth gear.

A tow/haul mode is retained on the Allison 1000 six-speed, but it is complemented by a new range selection feature. It allows the driver to select the desired gears, via a thumb-activated switch on the shifter, providing a feeling of enhanced control in unique driving situations, such as towing on a steep grade. The range selection feature holds the gear pre-selected by the driver and electronic safeguards prevent the transmission from being shifted in a manner that could cause engine damage or loss of vehicle control. Grade braking and cruise grade braking are only available when the tow/haul mode is selected and the transmission is not in the range selection mode.

Diesel-engine vehicles equipped with the Allison 1000 six-speed feature cruise control grade braking. Working in harmony with the tow/haul mode, the cruise grade braking system will automatically downshift to help maintain the pre-selected cruise speed when driving on downhill grades.

A new low-traction mode also is standard on vehicles equipped with the diesel engine. When the driver selects second gear while stopped and wheel slip occurs, the transmission torque-manages the engine to limit tire slip on slippery road surfaces.

In addition to the sixth gear and range selection feature, the Allison 1000 also benefits from complementary upgrades that include:

* Upgraded 310-mm torque converter that improves torque capacity
* New 22-tooth pump that improves NVH
* New solenoids provide better converter lock-up control and shift feel
* Upgraded rotating clutch that improves torque capacity
* New A40, 32-bit transmission control module

The Allison 1000 also has a unique, GM-patented elevated idle mode, which allows for faster interior warm-up of diesel-equipped vehicles. The system, which is activated through the vehicle’s driver information center, is synchronized with the engine. When elevated idle is active, the transmission increases the load on the engine so that it will generate heat more quickly and warm the interior in less time.

In 2004, GM Powertrain announced plans to introduce 10 six-speed automatic transmissions globally by the end of the decade. The introduction of the new Allison 1000 six-speed automatic is another step towards realizing that goal.

nm.. looked like the old round handle to me... I love the new 6 speed, used one from work to go grab a buddys boat from the lake yesterday, and bring it back into town... much nicer on the highways then the old 5 speed...

[iceburns288]

Nice truck, GMC pwns all

Is a 5" exhaust really gonna do anything?

[D'z Nutz]

Jit! When I saw the title, I thought it was your car! Awesome truck though
