When driving normal car sounds fine, but when I go over 3k rpms sounds like the exhaust on the driver side has just came off. but i'm still hitting full boost and haven't really felt any power lose any ideas?
Open your window in a garage and listen. If it sounds like a big redneck truck, you and I have something in common.
It dose, well it did last night when i was driving and would go WOT, but other then being nosiey as hell it seems to be fine.
Doesn't that your turbo isn't working extra hard to keep the boost up though. Let the car cool and put it up on jackstands. Grab a spray bottle of really soapy water and after turning the car on spray all over the headers and uppipe. Any leaks will bubble all up. If none then start at turbo uppipe and downpipe connections and then downpipe and work your way back.
Its at the dealer, The guy that put the motor together then hooks me up and is checking everything for free. But hes got to pull all my Exhaust wrap off the check the header. and the uppipe. But I'm leaning more towards the header being cracked cause it on the driver side and on the way to the shop it was a very noticeable exhaust smell in the car.
Well heres the kicker all the exhaust wrap off the header and up pipe is gone and still no cracks and no signs of a leak. So tomorrow hes pulling all the exhaust and replace all the gaskets hopefully that will fix the problem
Well as before no exhaust leaks Only making the noise while in any amount of boost. so IM thinking make the shaft has some play in it and the fins are just kinda hitting the inside of the turbo? I got a VF39 coming along with 06 injectors and a Bigger TMIC so I guess Ill find out next week sometime when i get it put on and then to Atlanta to get tuned
Are you recircing the boost? Check the recirc hose if so. Also make sure your BOV isn't leaking. I would do an intake pressure test.....if there's a leak you WILL hear it.
The oil line on top of the turbo seems to have a small leak ( which is i smelt burning) and as long as I don't hit and kinda of boost all the way till 6000 RPMS there's no noise but once I hit the gas and the needle jumps...lol its loud as sin and just horrible so I'm leaning towards the turbo, which is OK cause i just got the VF39 some 06 injectors for pretty much nothing.
