Naturally aspirated vs Turbocharged

[BlancNoir]

good day sir!
i have a 2012 forester xs (pre cvt era)and a 2017 forester xt, i prefer the feel of naturally aspirated here in the city but i think parang bitin sa akin ying 2.0, NA, but when i drive the xt, parang too much power naman, parang may whiplash ako,
parang iba din yung boxer engine sound ng NA ( which i like it more) compared to the XT
im thinking kung sana lng may 2.5 NA na forester dito sa pilipinas

there is no such thing as too much power.

i think too much for my personal need

Hello there, fellow XT brother! Mine is a 2016 model. The tuning output of the XT is just good enough - decent acceleration and speed. The XT feels soft off the line primarily due to its CVT tranny, a DCT would have made it a bit quicker.

Maybe a similar tune as the WRX S4 (300hp/400Nm) would make a bigger smile on my face. I am already even thinking just that. Hehehehe

Normally sabi nga is "no replacement for displacement"

Na introduce ang low displacement with turbo for fuel economy Lalo na kung city driving lang.

Sayang ang mas malaking displacement kung nausad lang or naka tengga lang sa trapik.

So ginawa yun mga lower displacement plus turbo para mas tipid. Yun lang nga at additional moving part sa engine kaya additional maintenance.

No replacement for displacement - it still applies but you can’t compare NA engines to turbocharged or supercharged engines.

The advent of small displacement engines is a good thing as you get more power and output from a smaller engine. Take the case of the Ford Fox 1.0L 3-cylinder Ecoboost engine, it produces more power and torque like a 2.0L NA engine. The Euro-spec Fox engine is rated at 140hp/210Nm.

Oops wrong thread. Deleted.

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)

N.A -

Advantage:
less movable parts meaning less maintenance

Disadvantage:
Less power if compared to turbocharged

Yung fun to drive na factor it varies from driver to driver...
Ako Pwede naman fun to drive kahit naka n.a pero katabi ko yung special someone... tapos more time pa kasi managal takbo ng n.a may excuse to spend more time together... hehe... yun nga lang pag may quickie, sa turbocharged na ako para mabilis umabot sa puntahan... hahaha... pero sa manila traffic, n.a or turbocharged same lang ng timeline sa pupuntahan...

With today's smart engines equipped with varable valve timing, neither turbocharger nor superchargers are needed. Even the EGR valve had been eliminated. Cars equipped with LIVC (late intake valve closing or atkinson engine) do not need neither turbo nor supercharger.
The reason for installing forced air induction is to increase volumetric efficiency of the combustion chambers. The relative time the intake valve is open is very short to efficiently fill the combustion chambers with air for optimum pressure hence optimum torque and horsepower.

"for those who want to squeeze 200,000 miles out of a car, the reliability of tiny turbo engines may still be an issue, experts say."

"toyota hasn't adopted small-displacement turbocharged engines on its high-volume products."

increased complexity = increased potential areas of failure.

i think this about sums it all.

my apologies. my quote was apparently from an earlier source.

No worries doc.
T is late to the game cause they know they need to make a reliable one. Maybe they perfected it already hence the release.

my thoughts are,
it's not yet perfect, but they have to get on the bandwagon, lest they lose a significant costumer base.
my guess is, unlike many of their designs that seem to have been in use for many years already, their turboes will undergo a more frequent re-modeling... "until they get it right."

I am curious about Toyota if their hybrid system has anymore room to develop as paired with petrol engines and, most especially, how their partnership with Mazda and/or Subaru is going to change the direction of their engine development as they move forward with their partnerships respectively?

the way i see it, and not limited to the auto industry...
...mergers upon mergers... and sometimes, de-mergers...

Well. T is now evolving...getting bolder then.
Actually, yes. They might be, as evident by their recent design release (not in asia).

T needs a partner when coming up with new things - Subaru with the 86, BMW with the Supra. If you want a home-grown Toyota that’s exciting, get a Lexus.

their hybrid system is super good already. they meet uk emissions now with their camry and rav4 hybrids. its just a matter of time before the battery plant in Indonesia starts supplying more batteries..
