supraturbochris Posted September 21, 2008 Share Posted September 21, 2008 Noticed last night. I was only traveling around town, when the first turbo cuts in slightly, there is a slight whine, but then goes when giving a little more throttle. anyone had this before? i have checked and nothing has come off. Serviced 2 weeks ago. Link to comment Share on other sites More sharing options...
mikeyb10supra Posted September 21, 2008 Share Posted September 21, 2008 j-spec or UK spec? Link to comment Share on other sites More sharing options...
miko_supra Posted September 21, 2008 Share Posted September 21, 2008 sounds normal to me. Unless it is louder than normal and there is a leak somewhere. Is the boost pressure ok? Link to comment Share on other sites More sharing options...

supraturbochris Posted September 21, 2008 Author Share Posted September 21, 2008 sorry its j - spec running bpu. Its weird, boosts up fine, hold boost pressure. just sounds a bit like a supercharger sound for about 2 seconds then stops. Bit worried really or is it just me being stupid?

supraGZaerotop Posted September 21, 2008 Share Posted September 21, 2008 mine does it to, you get the whine at first and when it get to around 2.5rpm, 3rpm it changes tone slightly to a faint drone for like 2 seconds and goes. thats the best way i can describe it, theres nothing wrong with my car, touch wood. its just the j-spec turbos.

Bobbeh Posted September 21, 2008 Share Posted September 21, 2008 I didn't think you get the whine on JDM turbos, they just disintegrate when the time comes. Link to comment Share on other sites More sharing options...

JamesG Posted September 21, 2008 Share Posted September 21, 2008 Mine whined for the 5 years I had the car (running BPU all that time). Never had any problems. Link to comment Share on other sites More sharing options...

bodilx6 Posted September 22, 2008 Share Posted September 22, 2008 well, its just the sound of turboes spinning up. The noise/whine (not to be mistaken for the 'death whine') is dependant of what speed the turbos are spinning. Apparently they whine a bit at spool up but into boost that changes to the more "sucking" induction noise. Also engine/exhaust noise will take over. So, no worries Link to comment Share on other sites More sharing options...
