Default no more screech + power up!!! YAY!!!!!

so... while I had the bumper off and the headlights out and had full access to all the intercooler hoses and conections I figured what the hell, I'll check it all over and tighten it up as a last ditch effort to fix the screeching problem.

I want you to know that on every single one of those hose clamps I got AT LEAST another 4 to 5 'slots' tighter on the clamp. Some of the clamps I got alot more than that. Thats like another 1/4 to 1/2 inch.

So now on a test drive I puttered up a steep hill in 4th at about 30mph and floored it and as the revs climbed it made alot of intake whoosh and turbo whine but no screeching and no weird fluttering!

So those of you who still have this problem... yank the front end off and get those clamps tight!

Hopefully mine stays all good now (knocking on wood, fingers crossed)

Default if this truly is the problem with the screech then I think you deserve to name it.

how about the Dani Mod.

I think I will have to take the front off and see for myself.

So you are stiil running stock intercooler hoses, right?

IF you are, why didn't you change over to samco? can they not go on the stock intercooler?

Congratulations on the find.

Default haha.. the dani mod lol... yeah I've still got the stock IC hoses

I didnt want to spend the 200 bucks for the Samco's yet... especially with taxes due.

I'll probably collect the hoses, a FMIC and a grill in the next year or so and put them all on together.

Default I like mod better hehe!

really it was rumored this was the problem all along... but then someone had their system pressure tested and found no leaks.... so I guess others assumed theirs were fine as well.

I wonder though if they only tested to stock psi levels when they pressured the system.

Default yes. I remember

it was attributed to wayward robots and not tightening the, or aligning the hoses at Gyor. I bet you're on to something regarding the torquing.

Now, I have an alterior reason to go in and to the headlighs, too. It does look better without the amber.

Default So, you think that leaking hoses were causing the noise?

How long did it take you to take the front bumper off the first time? Whose got the best instructions on how to do it?

Do you have to take the bumper off to get to those clamps?

Default maybe took half an hour after I got the car on stands and the wheels off

taking the bumper off is easy!!!!! I just went by that diagram thats been floating around. I believe its in TTakes2's fotki as well.

But yes... I've heard from several people that boost leaks will cause the same kind of noise.

and yep to get to some of them you need to take the bumper off and the headlights out
