As with most turbo engines, there is a small amount of turbo lag
at lower rpm as the engine spools up.
The couple of complaints I have after a weekend are that the engine does sound a little coarse and grumbles
at low rpm as Graham mentions above, and the transmission tuning did seem a little off as if it wasn't quite in the right gear a lot of times.
An electric actuator adjusts the turbine blades at split - second speed in response to changes in engine loads, enabling the unit to respond with the same lightning speed
at low rpm as it does under full loads.
Not exact matches
less weight, and more reps, is the same
as an cyclist spinning in a
lower gear, or a car revving up
at a higher
RPM.
As suggested in the manual, I have driven
at lower gear / higher
RPM for some time, and the light shut down.
As before, max torque comes on
low,
at just 1,600
rpm now, so there's never a feeling of waiting for turbo boost to build; the car just surges forward.
If I mash the gas to 50 - 75 % starting from stop lights, but still shift
at the same
low RPMs as if I was accelerating slowly I can consistently show a gain of 2 MPG on my daily drive over my normal driving style.
There is decent torque from
as low as 2500
rpm, but you tend to spend your time higher in the rev range because the 3.0 - liter six gets its second wind
at about 4500 revs and makes a delicious, creamy growl that wells
as you approach the 7000 -
rpm redline.
Power = Torque *
RPM, so
low torque
at high
RPMs can give the same power output
as high torque
at low RPMs.
Unlike many turbos that are lazy down
low, the pair in the Flex spool up quickly — all 350 lb - ft of torque is available
at 1500
rpm — making the Flex an adept urban runabout
as well
as a capable, medium - duty tow vehicle.
While it may not add a huge amount of oomph to the three - door,
as we found in our first drive, it turns the C30 into quite the hot hatch around town; peak torque comes
at a
low 1500
rpm and pulls all the way to 5000
rpm.
I'm also wondering why it kept the same 14,000 ish
rpm as other litrebikes despite having
lower stroke (around 17,500
rpm at 25 m / s), desmo valves, geardriven cams, and a perfectly balanced 90 degree V4.
Throttle response is not
as linear
as in a normally aspirated engine — you can definitely feel the rush of the turbocharger — but max torque comes on
at a
low, 1650
rpm, so it's not like you're waiting around for the turbo to kick in.
Suddenly the engine that sounded a bit agricultural
at low rpms on the street began to spit and hiss all manner of turbo and induction sounds, snorting, popping, and screaming its way through corners faster than anything else on site
as its monster midrange torque proved massively impressive.
Not only does the X1 feel larger and not quite
as hunkered down, the new turbo - four has a bit of throttle lag
at low rpm.
A valve pushes exhaust through a smaller gate to the turbo
at a
lower rpm;
as the engine
rpm picks up, the valve opens to create a bigger path to the turbo.
The 3.2 - liter V - 6 isn't
as smooth
as some of its rivals, but it emits a throaty growl
at the top end and provides meaningful torque from
as low as 2500
rpm, with additional grunt above 4000.
The 1.0 turbo three has adequate power
as well, though NVH felt rough
at low rpms and
at idle, and it ran out of power just past the midrange.
The six - speed's top three ratios are very tall, but this engine is flexible enough to pull decently from very
low revs,
as peak torque arrives
at only 1250
rpm.
NA would also not hit the acceleration marks of a high - torque -
at -
low -
rpm turbocharged unit and would probably weigh more
as it would need to be 12cyl.
This question is for the same engine and the same car
as in the following question: Likely cause of poor performance
at low RPM but normal
at higher
RPM?
Drop the hammer
at low rpms, watch the thin - line digital boost gauge escalate, and feel the whoosh of power
as the engine winds up, pressing you firmly into your stitched leather seat.
Anecdotal evidence (such
as it is) indicates that,
as you'd expect, removing deposits increases coolant flow, making the engine run cooler
at lower RPMs.
As always, turbo torque comes on low in the rev range — peak grunt is available at 2100 rpm — making passing on the freeway «silky smooth,» as downshifts are rarely neede
As always, turbo torque comes on

as downshifts are rarely needed.
A 1.0 - liter turbocharged EcoBoost three - cylinder will be the base engine in China, with a new 1.5 - liter turbo EcoBoost I - 4 tuned for high torque
at low rpms serving
as the optional powerplant.
I then put two brand new bolts and fit the intake right back into it's place but the car is now only shaking when the
RPM is dipping under 1000... it used to idle
at 1000 - 1200 but now it goes
as low as 500 and that's when the vibration is making the whole car shaking.
My question is closely related to one about a Jag dying
at low RPM, but is slightly different because it only occurs after refueling and because the problem persists after cleaning the throttle body,
as suggested by the answers.
At WOT (Wide Open Throttle) at very low RPM, the engine will almost stop, as if there is a big hole in the fuel map and it doesn't provide the correct mixtur

Sport + will also drop the redline from the usual 7,300
rpm to
as low as 3,700
rpm, based on coolant temperature, thus preventing cooking your engine when you are too busy to look
at the gauges.
Open it up
at low rpm, and BMW says the engine can go into a temporary overboost mode that cranks out
as much
as 370 pounds - feet of torque.
The 2.5 - liter's peak also occurs 400
rpm lower than in its smaller - displacement Japanese counterpart — whose peak torque happens
at the same engine speed
as the previous - generation U.S. - spec WRX.
As a side note, the 3.6 L absolutely screams, however all that high -
rpm power comes
at the expense of
low - end torque, which is one of the few areas that could be improved on the Wrangler.
Though the literal power band covers most of the operating
RPM range, particularly in first gear (
as there is no
lower gear to shift down to, and no «flat spot» in which the engine does not produce any power), the effective band changes in each gear, becoming the range limited
at the upper end by either the limiter, or a point roughly located between peak power and the redline where power drops off, and
at the
lower end the engine's idling speed.
Overtaking traffic with the M235i is a piece of cake
as the M235i generates maximum torque way down
low at just 1,400

It pulls well enough from the word go and fully gets into its rhythm
at as low as 1,400
rpm.
of torque
at 5250
rpm also displays good
low - speed elasticity and torque and remains
as manageable in heavy traffic
as any bread - and - butter engine.
That's one less pony than the Cherokee's 3.2 L V - 6, but the power comes in

When they were forced to substitute the poor gear range JATCO CVT, they had to over-cam their World engine, I - 4s from a lauded refined item
as Hyundai uses, into a «peaky»
low torque
at low rpm, noisy, apparent powerless, poor NVH, monster.
With a two - speed system, the higher gear allows the e-motor to operate
at a
lower and more efficient
RPM at high driving speeds, using the same principles
as a conventional gearbox with a combustion engine.
The new three - cylinder turbo EcoBoost engine isn't
as powerful
as the standard four - cylinder, but its healthy
low -
rpm torque output (that shove you feel
at low speeds) helps the Focus feels peppy enough in city traffic.
It does generate a stout 201 horsepower from its boosted four cylinders (the same
as the 2.5 L V6), plus 229 pound - feet of torque
at a
low 2,200

VTEC promoted more efficient «breathing»
at all engine speeds, meaning there was plenty of power available
at low rpm,
as well
as a satisfying rush
as the tach needle sped toward redline.
Longer - legged gearing (
as low as 2,400
rpm at 120 km / h vs. 3,100 in the manual) is one reason.
It's manifested
as a laboured vibration when lugging from

rpm (a speed that coincides with 100 - km / h in fifth).
Maximum torque doesn't come in

at 3500 to 5000
rpm).
Redline is
low at 6,200
rpm and power,
as expected, feels endless.
From a discreet pitch
at low revs, the engine note builds through the rev range, ultimately producing its trademark «bark»
as the 7,250
rpm red line approaches.
With the help of a sophisticated, electronically controlled, intercooled turbocharging system, the new Si offers the same peak 205 horsepower
as its predecessor, but
at a
