i still wold not suggest spiking that high, would be safe for a while, i did 26 for a few months, pulls like ****, but not worth blowing something up. I wouldnt trust stock hotside pipe with that much boost either.

If it is gas and not oil could it be just end tank boost leak or something and not the turb????

27 is a lot of psi, especially after 5k rpm. Most cars lose a psi or 2 at the top because the turbo can't keep up, so I'd say that's kind of odd that its gaining psi.

could be a boost happy turbo, my one friend has one, im jealous.

It seems weird that if you're doing a pull, it would increase in boost at that kind of RPMs, in fact it should be starting to taper off by then. Almost sounds like boost creep, but I've never heard of a balt having boost creep issues.

btw, im pretty sure i know the answer to this, but any cels?

FasterIsBetter

Yea, I would guess that too but its awful loud, man. I could see it being that loud if op was hanging out the passenger window but if it is a massive boost leak the noise will be amplified.

Could be

whats holding and whats spiking?? I dont controll it lol my car has always done it i just thought it was "the one" or something idkk???? theres always those good and bad motors of every motor!! could a boost leak be causing all of this and my turb be ok?,,,

holding is what the boost stays at constantly while doing a pull and spiking is whatit maxes out at for a short time and tapers back down.

Could a boost leak be doing this, yes. But we wont know until you check out your ic and charge pipe.

Cobe

Then why is my car spiking at 24 psi then when i go past 5 thousand rpms it jumps to 27 and stays there.... and it smells like gas not oil boy!

Take off you front bumper tomorrow and take as many pictures of the sides of your ic and cp As you can

Normally, if it was just that sound, I'd think it was a turbo bearing going.

A few years ago though, when I broke my stock IC, I had something similar happen to what the OP is talking about. The chunk that broke out of the intercooler was so big that you could hear the turbo spinning up quite a bit to try to get the airflow to the engine. The car would barely move under its own power and would go limp to a standstill.

I can also say (from experience I'm sad to say) that from the two times I've had a cylinder go the smoke was white for some reason, not the blue that you'd think it would be. I'm not sure why, but I'm wondering if it has some thing to do with being a synthetic or something.

If the smoke is white, he could be overspinning and damaging the turbo due to it not having any boost backpressure buildup, and the car keeping the wastegate closed in an effort to get more air. I would stop driving the car immediately.

Cobe

I will.. It smells like gas so tomorrow im gonna let it warm up a bit rev it for a sec and let some fresh **** come out the back and get a good fresh smell hahahahaha Then I will take the bumper off and the ic and both charge pipes and check them all for cracks... I have money to replace them all just hoping it isnt the turbo.. You have been such a big help man! thanks so much. tear down begins tomorrow

Cobe

So your telling me your intercooler was so messed up (possibly like mine) that the turbo is spinning and thats what the loud noise is? cause it is just trying to get air? Ill be on my way to zzp tomorrow after noon and get a new ic if thats all the problem is... Im so not hoping a turbo..

Stamina

You're probably very rich from an IC leak, so that's why you're smelling the gas. I'd be afraid that the turbo could be damaged due to overspinning it though too.

xbobbitox

Tune sounds to crazy, my car spikes like 25-26 and holds at 23-24 but all ways falls off when it can't hold anymore. Gaining boost on top end is weird lol

Stamina

Yep. The car is keeping the wastegate closed since it is commanding more airflow, and due to that and the turbo not having any boost pressure building up to put load on it either, you're spinning the crap out of it.

Cobe

dude im telling you my car has been that way since it was born... LMFAO i always gain 2-3 lbs after i hit 5k... I will post a vid of that after i fix these issues.

I will not be spinning it anymore then! fuuuccck that! do you think it is still okay??? I plan on taking everything off tomrrow and plan on seeing a fucked up intercooler!

Sir_Hiro

I wish I could voice my thoughts..but Eh...Im a LSJ..so Ill just be on mah way *leaves thread*

Stamina

After my incident, mine lasted for a couple more years (tuned) before the bearing/seals went. I only tried driving it about a quarter mile, to get to a parking lot where I could get towed from though. I haven't read the whole thread, but I don't know how much you've driven on it like this.
