Charge Air Cooler: Buy Now & Save!

hello everyone,
I have a Golf IV 1.9 TDI (not a PD engine); with a tuning box, I managed to increase the power to a respectable 129 horsepower.
I know that for sure, because I had it tested on a roller dynamometer.
'See the article about power boxes and the possibility of pistons burning out, but everything is fine for me.'
Now I have to say that it's working really well, but its performance decreases when the outside temperature is above 30 degrees Celsius.
Okay, I've heard that the Golf IV with a 150 HP PD engine not only has one glow plug on the right side, but also one on the left. If that's true, can I include it in my system as well?
or would it perhaps be better to install a fuel tank from Mercedes-Benz underneath the apron?

Sure, here is the translation of the text from German to English:

'Hello.'

Hello there!

If you haven't checked the nozzles, you can't know if everything is okay with the engine for the pistons.

The 150 hp PD model has the low-temperature coolant reservoir located centrally, in front of the air conditioning condenser and the water cooler (or between them).

A large air conditioning unit also has disadvantages: it requires a higher volume of airflow, which results in slower response times.
In my opinion, it hardly makes a difference without increased boost pressure anyway. When do we even have temperatures of 30°C? The cost of a larger intercooler with installation must certainly be around €800-€1000. For that price, you only get about 5% more power at 30°C.

The S3 has two large language models.

'I've already ordered a PDE intercooler and the intercooler from a VW Sharan, or Ford Galaxy, for next winter. I'm curious to see what the engine will say about it! However, I think you should only install one or more intercoolers if you use your car as a summer vehicle or even for short acceleration runs. A friend of mine has two intercoolers installed, and in winter, his car barely reaches 80 degrees Celsius over a distance of 50 kilometers – not fun when you're wearing a thick jacket! He doesn't care about the throttle response; he drives with 1.4 bar of boost pressure and has already driven 35,000 km. However, he's also done other modifications to his engine. But CHIP plus an intercooler is great; I've taken his 1Z up to 235 km/h, and the front wheels still slip and have traction problems in fourth gear on wet roads (if you provoke it, otherwise not).'
Bye, Matze.
