Little Help - Hijacked but still on topic

[Curt Luther]

I need to get 4 wheels/tires and 1 EZ Up to Topeka. Wheels and tires come back. Anyone got room? Compensation is available in the form of cash and/or lap dance tokens.

TIA

[Kurt Rahn]

Would Cupcakes be supplying the lap dances?

[Steve Ekstrand]

Kurt might drive the whale out and back full of tires.

[Kurt Rahn]

:gpower: Heel Moby!

[Steve Ekstrand]

Curt-

I'll do it for ya'.... Don't let Avard spread some nasty rumor that I'm 4Klbs overweight. Its a lie and I'll deny everything in court.

But that's my 5th set on board. The living room is quite full!

I owe ya, Steve. When are you leaving?

[Steve Ekstrand]

I'm leaving Tuesday morning early on the 9th.

I'm pretty flexible between now and then. I do have to pass through on the 10 on my way out to Palm Springs next week. Probably Tues, but not set yet. I need to visit grandpa in the desert before I leave and pick up the new sink topper from Mike Thompson in Colton.

I don't know about you, Kurt, but that doesn't look like a no to me.

[Steve Ekstrand]

Oh yeah, I could probably fit Ghazaleh and Kathleen in the trailer.

[Curt Luther]

Don't you want them in the front seat? ;)

[Steve Ekstrand]

A guy has to drive.... Priorities.

There are plenty of rest stops between LA and Topeka

[Ashley Armstrong]

They're mine. Hands off, boys!

Boys? I was just suggestin'...

[Tom Berry]

Curt,
If your deal with Steve dosnt happen.. we can help.
Tom

Thanks, Tom. This might work better 'cause you're closer and Steve sounds full. When are you leaving?

[Steve Ekstrand]

David and Stacey were both thumping me on weight. I do need to clear out the trailer a little. Though, the rig doesn't seem to have trouble pulling the worst grades of the I-5. But the I-5 is pretty docile.

it's not the engine you need to worry about. it's the brakes. and axle bearings. and maybe the tranny.

On the downgrades I just set cruise control at 45, 50 , 55, 60 whatever I felt comfortable with and the computer took care of the rest. Never touched the brakes. Speed modulated with small boost changes.

I could have gone any speed I wanted up the hills by constantly going down to 3rd, but we kept it easy and usually stayed in 4th at a comfortable pace. I'm working on reducing tongue weight as I only have like 5lbs margin on the rear tires.

Pretty weird, and impressive. Once we figured out how to read boost off the OBD2 port (scan gauge), it would run about 10 psi boost under turbo (exhaust) braking. My guess is that by having the turbo generate boost under braking, it makes the engine a bigger, or more effective, air pump than would be otherwise possible.

I'm not familiar with exactly what exhaust brake they are using, but most for these size engines are a simple flap in the exhaust pipe - the turbo isn't actually doing anything related to the process. It will completely shut down the flow. Of course, with the engine still turning it still crams air down there. I would guess this is boost you were seeing.

This is completely different than the big engine systems. they open the valves so the pistons don't have the helping hand of compressed air pushing them back down. the engine becomes total parasitic drag.

The 6.7 exhaust brake is actually referred to as a turbo brake.

First-ever Optional Exhaust Brake

For the first time in a Dodge Ram Heavy Duty truck, an integrated exhaust brake is available direct from the factory. Utilizing the 6.7-liter Cummins turbo-diesel engine's new turbocharger, the exhaust brake significantly improves control when towing heavy applications, such as pulling RV fifth wheels and horse trailers, providing added control and brake savings by transforming horsepower into braking power.

"Towing and hauling capability is critical for our customers, as more than 90 percent of Dodge Ram Heavy Duty customers tow with their truck," said Kunselman.

Benefits of the exhaust brake include:
* Increased vehicle control to provide the owner additional peace of mind
when towing
* Enhanced safety by reducing overheating and fading of brakes on
downhill grades
* Lower cost of ownership, extending brake life by as much as three times
* Capability for faster cold-weather cab warming

The 2007 Dodge Ram Heavy Duty's 6.7-liter Cummins turbo-diesel engine's VGT is capable of creating the maximum exhaust restriction through a wide range of operating speeds, improving braking performance at low and high engine speeds. Testing has shown more than a 30 percent improvement in retarding torque at 2000 rpm compared with traditional brake exhaust methods.

Six-speed Automatic Transmission with Electronic Range Select (ERS)

Mated to the 6.7-liter Cummins turbo-diesel engine is a new six-speed 68RFE automatic transmission, which delivers optimum fuel economy and performance. A new Electronic Range Select (ERS) system is integrated with the transmission, enabling customers to select desired gears that match driving conditions.

The new six-speed automatic transmission features a best-in-class gear ratio spread of 5.16:1, allowing for superior launch capability. The sixth gear, also known as the second overdrive gear, provides an extremely low rpm at highway speeds, improving Dodge Ram Heavy Duty's fuel economy and passenger comfort. In addition, an added compounder and two clutches provide optimal shift quality, improved quietness and durability.

The transmission's new ERS system complements the 2007 Dodge Ram Heavy Duty's tow/haul mode, allowing for driver-actuated gear selection with a shifter-mounted switch. ERS provides greater control in unique driving conditions, such as towing heavy loads on severe inclines. The system includes electronic safeguards to prevent shifting that could cause engine damage.

ELECTRONICALLY CONTROLLED ACTUATOR
The Electronically Controlled Actuator is mounted to the turbocharger bearing housing. The actuator consists of an integrated controller and a gear train that controls the position of the sliding nozzle ring. The actuator uses a signal from the Engine Control Module (ECM) to control the relationship between the sliding nozzle ring and turbine blades.

Moving the nozzle ring rearward or forward redirects the exhaust flow so that the turbine wheel spins faster or slower as needed

If the sliding nozzle is moved rearward, the turbocharger builds more pressure (turbine wheel moves faster)
If the sliding nozzle is moved forward, the turbocharger builds less pressure (turbine wheel moves slower)
VGT EXHAUST BRAKE
The VGT Exhaust Brake works in conjunction with the engine and transmission to provide an integrated braking system to help slow the vehicle. This is commonly referred to as exhaust braking. Braking power is achieved by modulating the sliding nozzle ring to restrict the flow of exhaust gasses from the engine, this will create high back pressure on the engine. The high back pressure creates a high level of resistance to the motion of the pistons within the engine and this resistance is used to reduce engine speed and thus vehicle.

The exhaust brake feature will only function when the Exhaust Brake Switch to the ON position. With the switch in the ON Position and the vehicle moving faster then 5 MPH; the exhaust brake will automatically operate when pressure is removed from the accelerator pedal allowing the ECM to see 0% throttle and 0% fuel delivery.

Turbo brakes are real nice, untill the actuator siezes and you are stuck with it in the on position. Nothing like getting the turbo to stall at 1200rpm from idle(500prm). fwiw, the DD/MB MBE4000 made 410hp but with all the braking options it had 535 brakeing hp. It had 3 stages, compresion brake, compression brake w/ low pressure turbo brake, and then with high pressure turbo brake, then another 35bhp from manually activating the engine fan.

Fun stuff. And in a way, I miss it. But I don't miss the traffic.
