i30 N DARK KNIGHT II

Even before the measurement, the technician said that all the i30N he measured had lower performance
Every i30N before the facelift, definitely. That's how I know it and that's how the dyno I was on always measured. But all the facelifts that my dyno has had so far have always been above the factory specification and that is also a thing that I have read from others.
 
I think it's a bit of a shame that your facelift is at the factory specification. Almost all the facelifts I've seen so far have been in the 290-300 hp range. If I'm interpreting this correctly, your power also drops at around 4000 rpm. I find that a bit strange. However, I'm not a professional and can only interpret a dynamo test like a layman.
Dyno measurements between dyno's can't be compared. Some read high, others read low.
 
Don't worry about this dyno score - you have 99% stock score - it is great.
My stock PFL on first really bad dyno point was 255hp or something like this and dude didn't know even how to use N mode.....
Intake 30*C is the reason here. You can lost 15-20HP easy due to outside temperature.
Use pipercross or k&n box filter and you will gain some torque score too.
If your dyno point have a bigger air fan in front - better score.
If your dyno man use some water on your intercooler - better score.
Best score - in the winter and first full N mode test after arrival.

Today's AMSOIL European Car Formula 5W30 oil test showed an excellent value of sulfated ash. A little lower fuel content in the oil than in the last test.

Today's AMSOIL European Motor Oil 5W40 oil test showed a low value of sulfated ash. Half the fuel content in the oil than in the last test. The factory filter was replaced with a filter from K&N. Finally, I decided to extend the oil filter change interval. The factory one was always replaced after a maximum mileage of 2500KM. For the filter from K&N, I set the replacement interval to 5000KM.

In February 2024, I tested this brand with a viscosity of 5W30. A large amount of sulfated ash was detected during the test. But the test of oil with a viscosity of 5W40 showed a low value of sulfated ash. This oil can be used for vehicles with a particulate filter.

In the next test, we will look at Motul brand oils. We will start with the 8100 X and test the 300V series over the next year.

Anyone who would have expected that a sports oil filter can cool the oil even one degree better will be surprised. Within the deviation of the measured values, they are almost the same as with the factory filter. Next year I plan to test a higher viscosity and if I have the tools I would like to test the oil flow of both filters as well.

@Bu11eT In the summer I tested the oil temperature on the circuit and after three sharp laps it went up to 129°C, so I'm looking forward to the summer test of 300V 15W50.

The oil was recommended by a member of our forum. Thank you @jeroenvde for the tip on the oil. This year we will test Motul oils. I chose 8100 X gen 2 as the first. It should be noted that oils with a viscosity of 5W40 are not suitable for use in winter and for short trips. But if you drive a lot of kilometers on highways, this viscosity is a good choice.

Finally, we have tests of oils that exceed the standards. Up until now, all the oils I have tested have been labeled Acea C2 or C3. For these tests, I replaced the gasoline particulate filter with a replacement from Invidia.

We will test the following viscosities throughout the year.

  • Winter 2024/25 - MOTUL 300V POWER 5W30
  • Summer 2025 - MOTUL 300V COMPETITION 15W50
  • Fall 2025 - MOTUL 300V COMPETITION 5W40

A little innovation in the table display, it should be a little easier to read for new forum members. A higher number of aluminum units was recorded in the test of the new oil. Aluminum contamination could have come from cans. Motul sells these oils in 2 liter cans. We will follow up in further tests.

@Bu11eT You were right, I am pleasantly surprised by the result of the test of this oil.

Finally it was time to install... Thanks to Forge for providing an upgrade to the components I owned for the pre-facelift model.

The Motul 300V 15W50 oil test went as planned. I have again slightly improved the format of the element results table. At some point in the future, the table will be updated and available with one click for all forum members.

The last test of the 300V series oils, high quality oils that surprised me with their composition. We'll see how they fare against the king of motorsport oils next year.

Next year we will test the CFS NT+ series oils from the manufacturer Millers Oils.

I think this British oil manufacturer needs no introduction. Its CFS and CFS NT+ series should be one of the best choices in the racing oil group. Its high molybdenum content shows that it is truly the king of motorsport oils. Just beware for owners who would like to run this oil with a particulate filter, as it has a high sulfate ash content.
