To Arbo, or not to Arbo, That is the Question

...Whether 'tis Nobler in the mind to suffer
The whooshes and buzzings of outrageous Four Cylinder Turbos,
Or to take snarls from a Sixpack of V-angled cylinders

Hyundai is dropping the 2-liter turbocharged four-cylinder engine on the 2015 Genesis Coupe, a company spokesman said.

"Each engine gave the Genesis Coupe distinct personalities. Models with the turbocharged four-cylinder engine felt more like a lightweight import sports car. Models with the V-6 resemble traditional American pony cars such as the Ford Mustang and Chevrolet Camaro with more power, torque and a deep, snarling engine sound."

The 2-liter turbo model that powers entry-level Genesis Coupes has a starting price of $27,245, including shipping. Pricing on V-6 models starts at $30,245.

First Ride: Mustang 4-Cyl. Convincing Enough

"From the passenger seat, the all-new 2.3L EcoBoost sounds and feels convincing enough, propelling the car with gusto through three laps on a short handling track about the size of a football field in the Charlotte Motor Speedway parking lot."

That V-6 represents the new Mustang’s base model. That means customers will have to pay more for two fewer cylinders with the promise of better fuel economy and more power.

Try Turbos?

No, Triturbos!

"That third turbo isn't powered by exhaust gasses though -- it's powered by electricity. That means it doesn't need engine load to supply thrust. It's there to fill in the gaps when necessary."

Buick on Boost - Your negst project?

Buick's gotta thang fur turbos.

[theholycow]

That turbo from the 1980s Buicks is from the 3.8. My 4.1 is the same engine (including the reinforced crankshaft from the 3.8 turbo) with a larger bore and 4bbl. That turbo would bolt right on.

That turbo also has a supply/demand condition that makes it unlikely that I'll ever own one.

There are thousands of them floating around so you don't want to get flooded with too many turbos? Yeah, we understand, you don't have to get one. No one wants to be buried alive by turbos.

Did I hear summon say "Married Alive"? This cite has rewls and regs and ewe aren't aloud to go causing panic by dropping the "M-bomb".

Forget Arbo, how about Arko?

Ferrari plans 20% CO2 cut by 2021
V-8s to get turbos; V-12s to get hybrid tech


Ferrari's turbocharged California T is 14% more powerful than its predecessor but emits 16% less CO2.
The supercar’s turbocharged 3.9-liter V-8 gasoline engine creates 552 hp and emits 250g/km of CO2 while its predecessor’s 4.3-liter naturally aspired V-8 offered 483 hp and emitted 299gkm of CO2

Dini said Ferrari would count on hybrid solutions to cut fuel use and emissions on V-12 engines, which are currently found in its top-of-the-range F12 Berlinetta and FF models.

Ferrari showed what is possible from this strategy last year with the introduction of its first hybrid model, the limited-edition LaFerrari.

The supercar, which costs more than 1 million euros before taxes, gets its power from an 800-hp normally aspirated 6.3-liter V-12 and a 120 kilowatt (equivalent to 163 hp) electric motor.

The La Ferrari has a combined 963 hp and emits 330g/km of CO2 while the model it replaced, the Enzo, offered 660hp and emitted 545g/km of CO2.

Dini said turbos are not a good solution for Ferrari’s V-12s because four turbo units would be needed to achieve the required improvements. This would take up too much space and create too much heat in the engine compartment.

Oooh... as a new convert to Audi, I'm likin' it.

Although, I always thought that an "electric turbocharger" was to be called a "supercharger." Am I wrong?
Edit: No, but, silly me, I didn't bother reading the article first! Actin' like my students again...

Also, I've seen advertisements for some kind of "Boost" dial to measure your "boost." What units is "boost" measured in and exactly what is it measuring? ("Boost" in physics is a change in reference frame requiring a Lorentz Transformation, so I'm all confused.)

Just found out the A4 loves 4 kRPM. My gas mileage is about to go to hell.

Boost units of pleasure may commonly be BAR or PSI

Boost units of pleasure may commonly be BAR or PSI

Ok, so is a good boost above 1 BAR/ 15 PSI or less?

I'm now going to guess that this is measuring the pressure in the intake manifold?

"Boost Units of Pleasure" Nice.

The more restricted the engine's breathing is, the more boost pressure you need for a given level of horsepressure. Lite boost might be 3-4-5 psi - just enough to punch up the torque and help out at the higher altitudes.

Serious is a relative term, but serious boost generally starts above 1 bar. Get enough boost and you have to worry about blowing open the intake valves.

BTW, In olden daze, some cars with huge, slow-turning engines had weak springs on intake valves and just allowed reduced pressure on "intake" stroke to suck open the valve. Exhaust valves were still camshaft-actuated, with stiffer springs.
