Hissing Sound

[vr2turbo]

And I rev to 6k RPM before with air cond on ever since I changed my extractor. Last time before that, I tend to switch it off because I need more power. Now with more power gained from the extractor, I din't bother to switch off the air cond anymore. This is bad.

Even got extra power, with air con on, still will take some power from your engine.......lol

Sadly, the hissing sound was actually the air con compressor. It was "Black Death". I just changed the compressor in Sept 2015.

However, there is no more load even when air con is on but a slight sound under the steering which resonance at 80km/h.

I think modern cars nowadays, usually will cut off the compressor if you are doing full throttle but yea old one have to manually off lol
