Lude Posted March 2, 2010 Share Posted March 2, 2010 i have metal hard pipes on the Intercoolers, and also on the Apexi intake to the turbo. makes a nice chatter/pigeon sound. (similar to a dump valve, but not as chavy lol) now on S14s, a lot of people used to remove the recirc valve, to get the sound. technically its the noise going back on the turbo blades, which will wear over long periods of time (aparently) do people remove them on the Supra? iv noticed on Single conversions you dont have them?

Guest Suprafly Posted March 2, 2010 Share Posted March 2, 2010 I thought it was the sound of the wastegate, hence the term wastegate chatter? Quote Link to comment Share on other sites More sharing options...
Lude Posted March 2, 2010 Author Share Posted March 2, 2010 its the sound of the air going back against the sound of the turbo fins, backwards, sorta like when you blow into a fan, and makes the noise lol. but without hijacking the differences, do many people remove them? i have the noise, even with the re-circ in, so wondered what would sound like when removed?.......

SupraD06 Posted March 2, 2010 Share Posted March 2, 2010 The 'fluttery' sound is compressor stall IIRC. Edit: I hear it on mine if you build up revs to just before the second turbo cuts in, then back off Quote Link to comment Share on other sites More sharing options...
Lee P Posted March 2, 2010 Share Posted March 2, 2010 That is correct its compressor surge that makes the sound not the wastgate like people think. You will still get compressor surge even with a dump valve but you will only hear it if you have an aftermarket filter and remove the airbox. I dont like running cars with no dump valve so would leave it on. its the sound of the air going back against the sound of the turbo fins, backwards, sorta like when you blow into a fan, and makes the noise lol. but without hijacking the differences, do many people remove them? i have the noise, even with the re-circ in, so wondered what would sound like when removed?.......

hadyn Posted March 2, 2010 Share Posted March 2, 2010 I ran mine without a BOV for a short while with a cone filter on. Couldnt hear any pidgeon or stall noises at all tbh... Quote Link to comment Share on other sites More sharing options...
Lude Posted March 2, 2010 Author Share Posted March 2, 2010 I ran mine without a BOV for a short while with a cone filter on. Couldnt hear any pidgeon or stall noises at all tbh... yea, i have metal intake pipe & metal IC pipe, so the sound reflects off that differently think Quote Link to comment Share on other sites More sharing options...

Its not as apparent on a stock twin turbo car because of the pipe work but it is there. Quote Link to comment Share on other sites More sharing options...
Lude Posted March 2, 2010 Author Share Posted March 2, 2010 so im ok to ditch the re-circ then on mine? i do love the sound, Quote Link to comment Share on other sites More sharing options...
AlexJames Posted March 3, 2010 Share Posted March 3, 2010 If you like the sound, ditch the re-circ id say... I get loads of chatter if I drive it correctly... let the turbos only quarter spool and then slowly ease off the acc... I always get chatter with that... its worth noting I am BPU+ but TTC too...

Lude Posted March 3, 2010 Author Share Posted March 3, 2010 yea i am BPU also, hard pipes, chatters like mad with the recirc still in, will remove it ont the weekend. jsut a case of blocking off all the pipes which conenct to it isnt it? nothing different on the supra?
