Yes, officially it had just 40 and 50kW, but back then, claimed outputs were often lower than reality. Common urban legend says, that good MPI engines reached around 55kW (and bad ones barely reached 50kW), but I cannot find any evidence.

 

This happens to other models with lot of HP but due to the tax policy of some countries the brands claim a little bit lower so there is no problem with the tax scale.

On dynamometer it's not unusual a difference of 4% between the same car models (stock, same year).

 

Many times on ''Dyno days' same models (stock) have a difference in HP between them and the owners tease each other.

In Greece the Felicia (stock) on Dynojet 248-E shown: 65,8 Hp/5500 Rpm and 10,25 Kgm/3950 Rpm

These are actually perfect values. 

@D.FYLAKTOS thanks for the info

Fifth gear is designed 'long' for fuel economy. Felicia 1.3 has not great acceleration in 5th.

 

My Felicia has 140km speed at 5500rpm with 4th gear which means the 5th has to give some more

IF i had a 6th then it could be an ''overdrive" for highways like Autobahn.

Acceleration and maximum speed are two different things. For acceleration you need torque. Felicia has not great torque at high rpm. Moreover, air friction at high speed is very significant. A higher gear doesn't add much speed, especially since the power curve goes down over 5500 rpm which for a family car is torture.

You need power both to accelerate and overcome drag. Engine torque alone is meaningless to describe vehicle's dynamics - Felicia 1.3 has torque peak at 2600RPM, but power peak at 5000RPM - best acceleration is achieved at power peak, because torque is multiplied by gearbox. 1.3MPI gearbox is actually quite good for performance - top speed is achieved around peak power at 5th gear (~170km/h @ 5000RPM).

Torque drop around 5500RPM is just enough to keep power constant when switching from 4th to 5th. If you switched earlier, you'd have more torque, but that'd be lost in the gearbox.

No one should have big expectations from a 1300cc Naturally Aspirated motor but depends from the road conditions.

Here in Greece we don't have 9 line highways as other countries,we have 3 line and the speed limit is 130 Km, if you run more than this limit you have a 350 € ticket plus you lose your driving license for 60 days.

That's why i have tested my real top speed of my Felicia, the days which i was running with 210 Km passing very close to cars are over permanently.

 

With 5th gear i have at 3500rpm the speed of 100Km and many times while moving on the right or in the middle line is enough to make an overtaking

If it's needed to do something quick i will shift to the 4th but i don't risk to stay long time on the left line because this is for the ''fast guys".

You need torque to get power. Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488. So, to make more power an engine needs to generate more torque, operate at higher rpm, or both.

@RicardoM Exactly. And Felicia has enough torque to generate most power between 5000-6000RPM, so for both maximum speed and acceleration, it needs to be kept there.

Specific on that level of high rpm (for that car because for a Honda is ''middle rpm") the synthetic oil is better than a semi-synthetic?

felicia wont last with ANY kind of oil at these rpm

I mean 5000-6000 rpm, if you "work" a Felicia intensive at this range (for example mountain road with no traffic) which oil is best? Semisynthetic or synthetic?

Obviously synthetic with a lot of film strenght modifiers.
Dont forget it is A 3 BEARING BOTTOM END
