2013 Model Year Quattroporte-5, increase in HP and Torque?

[flat-12]

I have a model year 2013 Quattroporte-5, there is a thread going on the "other" forum discussing some changes made to software mapping and lubrication that resulted in an increase of 10 horsepower and 20 newton-meters Torque. Can anyone confirm this?

10hp in a 2 tone car... you would not feel a thing.

 

[Wanderer]

And HP is a ruction of revs, so you'd probably have to rev it's ******** off......

'Other forum'........Surely isn't such a place

Suspect this was just for PR purposes...………….

The lubrication is this fancy diamond coating applied to the internals...low friction.

The Mrs and I use that.
What was the question?

And yet no different part numbers, or are there?

Yes. If you want to order cams for a Strad (which has the DLC - Diamond like coating) you have to provide an engine number.

Power is a function of engine speed and torque. Torque is the force applied and power is the work done. So torque is an absolute amount and power is the number of times that torque is applied over a given period of time.

So if you can make more torque at a given engine speed the power will go up. But also, if you can produce the same torque more often (I.e. at higher revs) power will also go up.

????? This confirms I am thick.
Didnt understand any of that.

I think the important point is that it makes brum brum noises. Unless it’s electric.

Honestly I’ve read this 5 times, Zep.
Still,Totally baffled.
I’ll stick to financial stuff. It’s far simpler.

Think of it this way (it’s a bit simplistic, but it paints the picture).

Imagine you pushed a 25kg weight along a track for 1 metre. The amount of force you applied can be calculated based on the weight you moved and the distance.

Now we add time, imagine you did it in 1 second. This now means we know the amount of force and the time it took, so we can work out the power (energy) you used because we have the amount of work done, and the time it took.

Now imagine you moved that same weight the same distance 20 times in 1 second. The amount of force needed to move the 25kg a distance of 1 metre stays the same, but because you did it 20 times in stead of 1, the power (energy) you used will be 20 times the original amount.

This is the principle in which the engine works. It applies the same force (it actually changes but that’s not going to help here) but it does it more often as the engine speed increases, which is why power is greater at higher RPM.

OP is interested in QPs, though....

And that coating isn’t in QP engines to my knowledge.

 

[Wagons-Lits]

this is interesting, according to Wikipedia's entry on the F136 engines and derivatives, it seems MY13 QP S's got the Sport GT S engine and the MY13 QP Sport GT S got the GT/M145 engine. DLC appears to be on all MY 12/13 QPs

the supporting evidence in the Wiki entry is both the Maserati academy bulletin and a MY13 owner's manual

if this is all true, you learn something every day!

Yes what he said.

What did he say?

Geez. Well thanks for taking it back to basics for me. Kinda understand , once the weight is moving I’m guessing it needs less force to maintain the speed?
My head tells me the hard bit is getting it moving.

In the real world it does take more force to overcome the initial stiction but not for this model.

The basics for an engine are that force (torque) is the effort provided and power is the energy expended based on the number of times you do it in a given period.
