i just gave my 33 a little fang up the street with a on spot u-turn and wen i got to the end of the street i notice that there was more noise coming from the engine bay... it seems like the fan is working harder or spinning more if that makes any sense... it is normal when the car is idling but if the rpm rises so does the fan noise or the fan rpm.... just sounds like this massive V8 roaring down the street with a huge as fan... not a rathered refined 6cyclinder turbo...
i didn't know wat to search for so yeah sorry guys...
