Naturally aspirated vs Turbocharged

[dropzone]

Good day to all!
i want to ask your knowledge regarding the advantages and disadvantages of naturally aspirated over turbocharged engines

1. same engine displacement ( different power output )
2. same power output ( different displacement)

which turbo engine specifically? mazda honda hyundai chevrolet?

Turbo - more power and torque

More maintenance nga lang

mazdas turbo engines produce more power but it does sacrifice fuel economy.

their normally aspirated skyactiv 2.5 is good but when they used a turbo on it. fuel economy took a hit. this is their generation 1 turbo petrol 2.5 engine. Better wait for the second generation turbo petrols.

mazda improved on their diesel turbo engines. i hope they replicate their success on their petrols.

Hmmm. Naturally aspirated vs Turbocharged

As I posted earlier... For me depende yan sa use mo ng car. Kung majority ng trip mo is highway, then turbo all the way... Kung matraffic ka lang sa EDSA, you may want to consider a naturally aspirated engine.

Using the 2019 Civic as an example.

1.8 is (strangely) lighter

Mas mataas nga HP and Torque nung 1.5 RS, but max output yun, never binaggit yung output nya at less than 2000RPM

So, the 1.5L engine from standstill will need more gas para pagalawin yung sasakyan.

agree, sa metro manila itll be better having NA ICE... no boost necessary sa traffic lol

^palagi kong napapanood sa Q&A about cars...

Q: kailangan ba i-idle ng 2-5mins yung turbo charged na engine bago patayin?

A: kapag high rev driving at gumana yung turbo - yes, kapag city driving at low RPM lang, di na kailangan since di naman gumana yung turbo

For me, NA is fine within City and if just cruising leisurely on the highway. The problem for NA (especially if smaller displacement) is when "fully loaded" or going uphill or both. =)

And in those scenarios, I'd really want to have a turbo on hand to tap into to get the power out from the engine.

If from my experience, you'd be fine with turbo'd engines within the city even if you are worried with consumption, as long as you try to avoid engaging the "boost" from the turbo, so keep those revs below 1800rpm. Hehe!

But my experience with turbo'd engines is for diesel pickup or SUV only. Don't have any idea about turbo gas engines if it "applies" as well. Since good torque is available for those diesels at around 1500rpm, sometimes lower (with some Isuzu engines).

I think with the 2.2 Ecoboost Mustang (or was it the Explorer) before, in City when not in boost, it was more fuel efficient that the 3.5L non Ecoboost version. But once the boost did kick in, you were actually better off with the non Ecoboost model. I can't remember exactly the article I read it from.
