Swampy442 Posted June 28, 2012 Share Posted June 28, 2012 So youre back to the realms of boost leaks then... Plenum bolts, lower runner bolts all tight? ICv bolts tight? Quote Link to comment Share on other sites More sharing options...
mellonman Posted June 28, 2012 Share Posted June 28, 2012 okay maybe put up a vid of this sound, i did just look at you other thread and you put in a pipe you cut down to size and from the pictures it doesnt look like a clean cut so this might make the noise if you dint clean it up, it is hard for people to help because we are not there to hear it, maybe get on the rollers somwhere so you can hear where its coming from, but if the car runs fine and boosts as normal live with it turbos do whisle even more so with a induction kit Quote Link to comment Share on other sites More sharing options...
Lude Posted June 28, 2012 Author Share Posted June 28, 2012 thanks for input guys. il get a video up soon of it. i was fitting the turbo 9pm last night just so can take the car to a wedding today :-) im getting ready to go now so il report back in a day :-) at least iv got a new hybrid turbo now lol Quote Link to comment Share on other sites More sharing options...
antno Posted June 28, 2012 Share Posted June 28, 2012 does it sound like a jet? my car sounds like a jet and always has since i bought it i can hear alot of air and carnt find no leaks and im not sure if it should sound like this because i havent seen another turbo supra on the road Mines the same as well. First turbo doesn't seem all that responsive but it is comparing against the second one. I know the second one is ment to be a kick in the arse but the first just seems to be an added noise Quote Link to comment Share on other sites More sharing options...
ashbuster Posted June 28, 2012 Share Posted June 28, 2012 ive had a few supra owners in the car now and they say its normal bud Quote Link to comment Share on other sites More sharing options...
Lude Posted June 30, 2012 Author Share Posted June 30, 2012 VIDEOS ive just recorded 3 short videos of the sound. i think some of you may say its normal. but some will say its whistling too loud. it is whistling too loud for me, and i dont think it should be as loud as it is..... any ideas? just to confirm its boosting fine & second turbo comes in fine.

ashbuster Posted June 30, 2012 Share Posted June 30, 2012 thats loud for stock twins surely has to be a leak Quote Link to comment Share on other sites More sharing options...
welshbuddy Posted June 30, 2012 Share Posted June 30, 2012 through a housing estate , Loud whistle, but if its boosting fine Sounds cool when ya driving off ha Quote Link to comment Share on other sites More sharing options...
listy Posted June 30, 2012 Share Posted June 30, 2012 Got to be a leak mate as you have changed the turbos. Mine has a soft whistle with an aftermarket intake. Its nothing like that though. Way too loud imo to be a normal thing. Quote Link to comment Share on other sites More sharing options...
Lude Posted June 30, 2012 Author Share Posted June 30, 2012 ye know too loud. dont know how the hell to find it though. would it be a vacuum leak through a small pipe? boost leak test didnt point to anything. any tips how to locate be great Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted June 30, 2012 Share Posted June 30, 2012 (edited) Have you tried pressurising the system manually? I.e. using an air line. There definitely a leak there though. Check all the bolts on the intake manifold, ALL the bolts. Edited June 30, 2012 by Swampy442 (see edit history) Quote Link to comment Share on other sites More sharing options...
ashbuster Posted June 30, 2012 Share Posted June 30, 2012 did you change the gaskets on the manifold and tb after you had them all apart? or did you still leave the old ones on? Quote Link to comment Share on other sites More sharing options...
Lude Posted July 1, 2012 Author Share Posted July 1, 2012 yep iv put an air line in engine twice and put soapy water in various places and not found leak. and smoke test too with a fag. the intake manifold bolts and throttl body have been checked, the same gaskets were re used but iv read they are re usable, and boost leak t test wasnt showing signs of leaks there. would you say its coming from a splut vacuum pipe? or a larger area metal surfce leak? the intercooler itself maybe?

listy Posted July 1, 2012 Share Posted July 1, 2012 May sound silly, but have you checked the IC piping itself? Is it possible a silicone hose has split/come loose? Or even a split in one of the pipes itself? If there is no sign of a leak in the bay itself, I'd check the intercooler mate. You could rule that of the list then at least.

mellonman Posted July 1, 2012 Share Posted July 1, 2012 when you took off the turbo piping did you touch or adjust the intake air control valve its the one one the long straight pipe near the second turbo, i believe that it might be open alittle and pushing you first turbo boost into the second turbo, just a idea as that does not sound right at all that is not a vac leak way to loud for that, its got to be intake or boosted piping Quote Link to comment Share on other sites More sharing options...
Lude Posted July 1, 2012 Author Share Posted July 1, 2012 checked the ic hoses and samcos first. removed and put back on still same. will have to do a boost leak test on the intercooler itself and see if any bubbles come from that itself..

Swampy442 Posted July 4, 2012 Share Posted July 4, 2012 It's in a box with a vsv on the side. Quote Link to comment Share on other sites More sharing options...
Lude Posted July 4, 2012 Author Share Posted July 4, 2012 It's in a box with a vsv on the side. this part yea? how would i go about checking or adjusting this then? i didnt really alter anything, just removed the pipe and disconected the actuator from the body of the pipe...

SupraD06 Posted July 4, 2012 Share Posted July 4, 2012 Lude i think mellonman is on about the vsv on the pipework you painted, in the picture above you posted its the vsv on the far left pipe. It looks like a little dial / adjusment thingy. Id be interested in knowing aswell as i took my all my pipework off the other day to paint, and although im yet to get it all back together i was looking at that dial because mine just turns and turns both ways without felling like its doing anything? Can anyone shed some light on this? Edit: You already know what part im talking about lol Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted July 4, 2012 Share Posted July 4, 2012 this part yea? how would i go about checking or adjusting this then? i didnt really alter anything, just removed the pipe and disconected the actuator from the body of the pipe... http://i181.photobucket.com/albums/x169/lude200/iacv.jpg That's it. You don't adjust it, what's inside is a reed valve which stops boost from no1 turbo entering no2 turbo. Ive had it before where my aristo made a honking noise, like a goose, if you revved it at idle. One of the reeds had lifted slightly. Quote Link to comment Share on other sites More sharing options...
SupraD06 Posted July 4, 2012 Share Posted July 4, 2012 So have i broke / damaged mine by turning the dial thing? Quote Link to comment Share on other sites More sharing options...
