Where is everyone #5

Excellent post.
I suppose I could "forget" to send that second text to Santa this time.

 

@johndeere4020 you're right, the 36 has a larger diameter spring and was actually slightly longer on the one I cut open versus the 30.

I'll have to admit cutting the collar off to see what it looked like inside is sketchy, but sometimes I cant help tearing stuff up to see how it works. Been doing since I was a kid lol

 

I've said it numerous times on here...I freaking love my disc brakes!! Lol! Don't get much fade and I do believe they have saved a few dummies from getting run over by me.

 

Just in case -

There’s this one here, might be nothing, but I don’t like that darned outfit, and Mum sounds worried -

1st week on the road

Don’t sound right to me - with the network we have available . . .

 

Turbo blankets are good for short peak power intervals, but not so good for extended duration.
Here's why, in a short burst of required energy, a percentage of the drive gas is lost because the turbo shell and turbine steal some of the heat as it was cooler before the burst. As the metal heats it expands which also creates a slightly larger air space to pressurize and this extends the turbo lag. So by wrapping the turbo in a blanket to maintain it's heat, it's already warmer so therefore there is less parasitic heat loss and more energy captured.
The downside to this for guys who do really heavy long torque loads is that without the parasitic heat loss of external air passing over the shell, the turbo can and will absorb more heat under these extended durations, which can cause the turbine wheel to expand more than it's acceptable limit resulting in turbine drag or interference. It can also lead to heat being reflected back into the exhaust tract of the head, which the coolant must then work to dissipate.

Now post turbo exhaust pipe wrapping is slightly different. As the gasses travel away from the turbo they are continuously cooling. As these gasses cool, they become more dense than the hot gasses trying to push them out the stack. Of course the dense gas has physical advantages over the less dense gas, so by wrapping the exhaust pipe post turbo, once the pipe has absorbed it's heat load it maintains it as the wrap inhibits heat transfer, therefore reducing the cooling rate and thus the density rate making it easier to expel the heat.

The whole principle of an ICE is to harness as much heat energy as possible...inside the expansion chamber (cylinder), and then to expel it as fast as possible, because once it leaves the combustion chamber, it is no longer capturable energy, it is parasitic energy that must be expelled.

 

You physicists make it sound so simple.

 

Yes, but we students lap it up.

 

If your headed north bound with 80 k gross I top that long grade right before the tunnel in 9th gear (direct) 67 mph 30 psi boost at 700 on the pyro in the winter I wont ever make enough heat to turn the fan on. Summer I flip it on at the bottom gauge barely moves.

 

It is simple.
Q)How do you eat an elephant?
A)One bite at a time.

Take a complicated process and break it down to each individual step. Work on one step at a time...that's how you eat a complicated elephant.

 

The Extra braking force is provided by the Extra " swept area " of the shoe against the drum. Not extra pressure from the spring.

The larger shoe has more friction ( grip ) .

If a Truck is sliding off the road from bald tires, it doesn't matter how much force the Driver pumps the brakes to, it won't stop.
It needs more grip ( friction ).
Better tires.

NOT more pressure. More grip.

The larger shoe ( 36 ) provides the extra grip, not the spring.
