Had turbo rebuilt last month with a WW. Truck runs well but I noticed a noise at 1500 rpm which continues through 2000 rpm. louder with more throttle. Goes away, or I cant hear it, past 2000k with heavy boost.

I read most of the previous posts regarding the increase in noise with the WW. This sounds different than turbo whistle.....more like a high freq. humming/howling.

Just curious if thats the WW noise...want to ensure no more turbo issues. Pulled my buddies 26' center console boat (7000lbs) sunday back from Texas coast. Trucks performance was excellent with 13.25 mpg average on highway.

Added an AIS when turbo and removed EBP stuff in pedestal and outlet was reinstalled as well. Stock exhaust for now.

 

anything like whats here...

yeah, pretty much the same. It must be the resonance the one guys talks about. I had the turbo built by Majestic in Waco, TX and they have a real good rep arouund here. Dont really care about the noise...just wanted to make sure it was normal.

I just rebuild mine last month with a WW and it a lot louder than the stock wheel. Much different sound too.

 

do you have that tone at 1500 - 2000 rpm? Not boost whistle but the higher pitched resonance.

 

I tried to hear something this morning but from 1500-2000 I reall don't hear anything because of how loud my exhaust is. After 2000 I can really hear the turbo.

 

Yup...resurrecting from the "dead". Any update Sponge?

 

No. I am just going to assume its from the WW. Checked eveythg and it all seems fine. About to put a fender sleeve in when I install a 4" exhaust so it will be interesting to see if it changes.

 

good luck man. I personally went thru the trials/tribute, to a foiled cac pipe, blocking off the zoodad mod, exchanged turbos with a non-w.w one..(now i have spare ), blocking holes in inner fender..etc, you name it, and for me, no change.

You by chance have a 6sp? Mine, just recently started making a "sand in a metal can" noise. Goes away with the clutch depressed. Starting to lean, for me, a trans issue...

 

No I have an auto. Good luck and Thanks for checking on my situation. For me. I have to temper my OCD when it comes to my truck, and other things! I think a lot of us on the FTE tend to get too wound up over stuff....myself included.

 

Yup, but its a whole new ballgame, with these beast. Myself, purchased it because i wanted the satisfaction of being able to tow ANYTHING, and with that purchase, to be the "last' truck i buy. So, when noises, quirks..etc arises, well, it puckers the keaster and truck needs attention..lol

 

Yeah I agree. I was a jet mech in the Marine Corps so I tend to be very intense with maintenance and repairs. I helped a buddy tow a 7k lb saltwater boat last weekend and was blown way how well it did. Lovin the diesel!

 

timmyboy76: UPDATE

I finally drove an early 99 (actually an ambulance we have here a work) and it has the same turbo noise. That confirms for me its normal and just associated with the wheel.

Also had a lingering oil leak that i attrubuted to my r&r on the turbo. This weekend I replaced my IPR and HPOP lines...between the two the leak has stopped.

 

Sponge, from seeing your "new" thread, thought your still chasing the noise, and was hoping the F-550 turbo wasthe fix. Anyway, you found that ur noise is normal. I too went ahead and pulled the ZF6, installed new clutch asy, input shaft repair sleeve kit, turned flywheel...etc, the works when replacing t clutch, and NOPE, noise still there. I think mines internal of the trans.

 

that sucks. hope you fingure it out soon. Mines definately the WW and mirrors the stock E99 truck i drove so im relieved nothings jacked up
