specs:
2008 evo x
AMS intake
tuned
teens miles.

all of a sudden on the freeway at 3k+ on wot car starting whistling like the ac defrost was on full blast by the passenger front window.

only when i accelerate wot at 3k + this happens. when im cruising or not doing wot it does not happen.

any help is appreciated

 

probably, this just happened to me in my '04. took it in for what i thought was a boost leak, and got a phone call saying i need a new turbo.

does it blow any smoke?

 

there is no smoke blowing out of the car..


what do i look for if i have a boost leak
what about a blown turbo?

trying to figure it out before i start reverting back to stock and taking it in for service..

 

im going to start putting on stock parts and googling how to save my custom tune

any help in the time being is appreciated +1karma

 

When checking for a boost leak you want to check all the pipes and the tightest of the hose clamps. (on the boost side of the system)

 

i think youre fine, intakes usually cause that loud noise, its just the turbo spooling....i think.. gl tho

 

Worst case, a piece of the piston flew out and damaged the turbine blade. Chipped or bent turbine blades usually make that whistling sound when you are on boost. Check your spark plugs for damage and do a compression test. If possible, use a borescope to look inside the cylinders for damage thru the spark plug hole.

 

Do you have a boost gauge? What kind of boost are you seeing when this occurs?

Compare the results to when you remember the car working and as others have stated, you need to do a boost leak test ASAP. I wouldn't be driving the car around until you get this checked out.

 

im going in to see a mechanic before i take all the parts of and revert back to stock. will update..

basically what happened was on the freeway at 80/hr 5th gear all i hear is swoosh loss of acceleration and air going thru my front passenger defrost vents

 

$1 days you blew the coupler off your turbo outlet, or tore it

 

I think its a torn coupler too. Maybe a hose clamp came off.

 

Sounds like a boost leak but if you haven't upgraded your uicp/licp/fmic then it isn't too likely.

 

Happened to me the other day, intercooler pipe popped off. Exactly how you described it too.

 

sounds like like the a pipe came off.

 

ok i had the same a couples of weeks ago.....so i ordered a FP RED and a test pipe(because i had an high flow)......when i took of my high flow it was completly destroyed....

with my stock turbo in hand...im like it looks good........so probably my high flow did th¸at....you might want to check that before buying a new turbo!!!! it takes 5 minutes if your not dropped lol.
