Kate Posted March 6, 2014 Posted March 6, 2014 Hi AllThis might be a really stupid question but is the whistling sound my turbo (it's really loud). I've had quite a few problems with my car and since I fitted the HKS actuator it's made this noise, I don't know whether this is just the turbo I am finally hearing or not? All I've been listening to since I got it was boost leaks etc.....Hopefully this vid works. Quote
Dean_mc88 Posted March 6, 2014 Posted March 6, 2014 Mine is making a noise similar to that and I thought it was just boost leak but mines way more noisier than that Quote
Dean_mc88 Posted March 6, 2014 Posted March 6, 2014 Also this noise only started when I thought I had fixed the boost leaks I have an HKS actuator and hybrid turbo I bought a new turbo just incase I had blown it because I had fixed all the leaks Quote
Kate Posted March 6, 2014 Author Posted March 6, 2014 Oh god I hope my turbo isn't gone! I saw your post but yours chatters too doesn't it? Quote
Dean_mc88 Posted March 6, 2014 Posted March 6, 2014 because I don't have any BOV that's why it chatters Quote
Kate Posted March 6, 2014 Author Posted March 6, 2014 Oh ok, ahh do you think there is a problem with mine then? It hasn't picked up the noise that well as it is quite loud. Can you let me know if your new turbo stops the noise please when you fit it? thank you x Quote
Dean_mc88 Posted March 6, 2014 Posted March 6, 2014 im in Singapore for the next two weeks so wont be giving you an answer for a while. does it still boost properly or are you finding it sluggish? Quote
Gainzy Posted March 6, 2014 Posted March 6, 2014 What boost are you running? Are you losing any at all and do you have a boost gauge? Just sounds like spool to me... Quote
Dean_mc88 Posted March 6, 2014 Posted March 6, 2014 sound I have a spare turbo hahaha mines slightly more high pitched but im running higher boost than stock Quote
Gainzy Posted March 6, 2014 Posted March 6, 2014 Mines very whiney more whiney in the cold you would know if it's boost leak if you have a gauge... Quote
Kate Posted March 6, 2014 Author Posted March 6, 2014 Well because of all of the problems I have had I set my boost to .6 so when I was fitting everything the boost wouldnt go through the roof before getting it tuned. I will see what happens when I put the boost up once last bits are fitted It has only felt sluggish because my boost setting is really low at the moment so i wouldnt be able to tell lol! Thanks, once again, guys Quote
Socks Posted March 6, 2014 Posted March 6, 2014 As long as the hks actuator has taken up the slack... but not too tight... That's fine... You will get more whistle if your building more boost then you were before.. What boost are you building now? Quote
Ollieh17 Posted March 6, 2014 Posted March 6, 2014 around 6-9 secs that sounds like a leak to me. Sounds too high pitch to be spool. Didn't you have a problem with a leaking dumpvalve? Quote
Kate Posted March 6, 2014 Author Posted March 6, 2014 Socks - only running .6 as I had all the problems so set the boost really low. Ollieh17 - No, I had a huge hole in one of my intercooler pipes but that has been sorted and the actuator I had on was shocking but obv that is sorted now. Its just really strange that I haven't heard this noise at all until now.... Quote
Dean_mc88 Posted March 6, 2014 Posted March 6, 2014 I've just sent my recording to my mate who used to own the car and he says it's always sounded like that so I'm just going to leave it for now and let him drive it when I'm back just to double check Quote
Ollieh17 Posted March 6, 2014 Posted March 6, 2014 Fair enough, mine used to sound like that when booting it and i thought it was a leak. Then the turbo completely died, shitting oil all in the intercooler pipes Quote
Dean_mc88 Posted March 6, 2014 Posted March 6, 2014 as I said ive already bought a new turbo so il be stripping it and rebuilding it just to be sure now you've send that Quote
Liam_D Posted March 6, 2014 Posted March 6, 2014 Sounds like a boost leak to me to be honest, turbos are noisy on starlets when spooling but not usually that loud. Do you have a boost gauge? What boost are you getting? Quote
Kate Posted March 7, 2014 Author Posted March 7, 2014 I thought a boost leak noise would me more of a "whooshy" sort of noise (that's my technical term for it) I have an electronic boost gauge but like previously mentioned it's set low anyway... I've got someone to come and have a listen to it on Monday just to be sure. We will see Quote
