Ok so question. How do I know if the turbo is done or not? I did a pull in 2nd gear on the way home last night and I heard what I thought was a backfire. Lost boost after that. I'm use to the 5psi flutter but I'm not building any boost at all and there is no blow off even in the slightest. It sounds like air is just whistling through it all. I didn't have a flashlight so I couldn't look into the intake side but I put my hand in there and the fins spin fine. It has to be something with the turbo if it's not building any boost at all right? If anyone has a suggestion that would be great. Need to get this figured out so I can decide if I'm going to order a new turbo sooner rather than later.

 

Look for a boost leak....

 

checked all my pipes and they're solid. Had just installed a new FMIC 2 days ago and I redid all the pipes. Everything is intacked.

 

Just because they look intact doesn't mean they are. Check codes.... Check for exhaust leaks

 

They are intact because I checked them all, I have no way to check codes until tomorrow due to my laptop being down and I'm stuck at work. Hopefully it shows me something. It's puzzling me because it sound like air just whistling through and the turbo isn't spinning. If I didn't have to work today I'd be under, over, and in my car figuring this out.

 

It's also possible that your IC cracked. I had a Hahn IC blow a weld once.

 

Couplers can have a hole, ic can be cracked. I blew my Hahn ic up a few times..

 

That would blow, especially since it's a brand new intercooler. I wasn't able to take off my bumper last night to check for a cracked intercooler but I'll probably do it tomorrow. Just trying to make a list of things to look for when I get the chance.

 

Boost Leak Test?

 

gotta build the part for it then I could, I'm hoping it's a massive boost leak somewhere and not my turbo being blown.

 

So scanned the car and no codes present. Gotta look under the car to see if anything else is jacked up. Still cant find any boost leaks, gonna do a boost leak test tomorrow I hope.

 

The symptoms you describe do not fit a blown turbo. Just sayin'.

 

that's a relief. So a massive boost leak? Just trying to figure out where it could be that I wouldn't be building any boost in the slightest and why it just makes a whistle noise.

 

Yes, that is what everybody is saying. The air noise is all the air leaving/entering the system. Blown turbos usually make a different kind of sound and make smoke too.

 

cool and it's leaving in a hurry too since I"m getting nothing. I'll put it on stands when I get home so I can check it out.

 

Sub'd

 

i dont think i seen this mentioned. but Bypass vavle might be bad.

 

i blew off the hose clamp that goes into the intake manifold. i had the same symptoms as you (no boost, could hear the turbo spool, popping noise then no power), and i didn't see that it was off at first. (i just had done my charge pipes the day before) but yeah, pretty sure blown turbo would smoke all over the place and rattle like a ****

 

I cant really hear the turbo spool, what I hear is a whistling as if air was coming into a small hole or something. BPV def isn't making any noise, will check that out. Checked the intake manifold, its still intacted. Really gotta get under this car to get a better look. Still stuck at work so I'll get off late and have to come in really early tomorrow. So tomorrow after work I'll be able to check it out. Till then I'll just park it and hitch a ride

 

my car still makes a sound like air coming out of a balloon really slowly when i hit over 10psi. lol. idk what the hell it is, but it pulls fine, so ef it.

but yeah man just gotta be patient for now!

 

After I put my ZZP intercooler on it ran fine. No more CELs and everything was legit. I got happy and did a pull and now I'm not happy because I have no more boost. Hope it's a simple fix.

 

Blown turbo?
How long/far can you drive on a blown turbo? and any reconmendation on how to do that?

 

When my turbo blew it sound like the turbine inside the turbo was just spinning... I was pushing no boost either... I wouldnt say over 100 miles man... then mine got very very bad and actually scared me... starrted to chatter and **** and blow black and white smoke... By the sounds of it im gonna be the one to say it does sound like you have a blown turbo... I went through the same thing and ripped my whole car apart.. PRAYING it was a end tank.. nope

 

Cobe I had high hopes it was a boost leak until you chimmed in haha. Man if it is I'm gonna be sad. Have to decide if I want the Hahn s20g or the ZFR now. Any suggestions?

 

Just get a s20g now haha jk man I hope it's not your turbo. From everything your saying tho it sounds like a boost leak for sure.

By any chance did you use hairspray to get the coupler really stuck onto the charge pipes?
