Turbo whistle flutter

[565bbc]

So my wife took my truck to the store the other day and I noticed as she drove down the street (light throttle) the whistle from the turbo didn't sound smooth. It had a fluttering sound to it. When your in the truck it doesn't sound like that. Is that normal or is that a sign of it going out? There is a chip on each of the edge of the turbo fins but don't know if that would cause it to sound like that. Just wondering if anyone else ever heard of that or would know what would cause it. Thank you in advance.

I would replace the wheel and inspect your intake for leaks/cracks. Check the turbo shaft for play, too, might be time to rebuild it.

I have a stock wheel you can have, great shape, $35 TYD. A wicked wheel is about $78 from XDP.

Where would I be able to find a rebuild kit for my turbo?

Well, you need to take the intake off first and find out how much play there is in it to determine IF it needs to be rebuilt, first. Do you have a boost gauge?

Bob/Guzzle has the kits, and is great to deal with, great customer service and VERY fast shipping!

IF it is bad, you would need to pull it out/apart and figure out just how much neesd to be rebuilt, might just be a new bearing/seals, might need a new turbine/shaft, all depends. There is a very helpful video in the 7.3 tech files that shows how to remove the turbo.

As far as removing it and replacing it that is no problem I've already had this turbo off already when I changed the up pipes. I figured for the amount of miles this motor has on it (over 486K) it wouldn't be a bad time for an over haul on it since It'll be off anyway (again). It really doesn't have that much play to be honest with you, maybe about 1/16" or so, so why not rebuild it while in the process of changing the wheel. And no I don't have any kind of aftermarket gauges (yet) I appreciate the info though

It will have a flutter to it. Its not a stright and loud as a 6.0. All 7.3s I have heard stright piped have a bit of a "paulse" or "flutter". I like it!

That's good to know guys I thought something was wrong with it. I'm going to eventually go through and rebuild the turbo and change the wheel out but I'm gonna try and run it a little bit longer like it is. Does anybody know what causes the 7.3's have that fluttering/paulse sound to em?
