thanks to clay for getting mine to me so fast, my factory turbo hit the dust by sounding like a power steering pump at 2500 rpm, well i installed the ball bearing today and it has a loud howl along with the high pitch whistle, is this right im not sure what the boost is yet, my scan gauge is coming tomorrow but mine is all stock no chip and she runs a bit better, please guide me on what i need to do. Thank You

 

From what I hear the gt38R is a very loud turbo there will be some more guys along shortly that will give you some more advise


I'm still deciding on what turbo I'm going with to go with my hybrid injecters next spring

Aint it sweet?! It's music to my ears. Only problem is, I've gotten so used to it I have to "listen" for the sound now in order to hear it.

Haven't turned on my radio in a year and a half, the 38R is music to my ears..the sound of power.

 

I don't have much of a howl with mine..mostly all whistle with some chatter at WOT and when I let off it real quick...mine is also a brand new unit less then a year ago..Garrett changed things a little not long ago....I think Clay's are rebuild's aren't they?? still new but the older style..i love how mine sounds..just like riding in my big truck all day long...

 

Mine had the howl/siren sound. It had a few other sounds at particular PSI, then it blew up on me at WOT. My new one is A LOT quieter and doesn't have the howl, just a nice quiet whistle.

 

Mine is quiet cruising around town and down the highway 0-10 or so lbs boost. Get into it and it has a beautiful whine/whistle to it. When I first put it on, it had a funny old school quiet mechanical siren woooooooo to it while a SLOW ROLL or coming to a stop. After about 1k miles of towing (10-15 lbs) of constant boost, the woooooo went away and hasn't done it since.

Everything I am discribing is the TURBO sound I hear through the firewall. Not intake or exhaust sounds.

* My 38R has a DieselSite ported shroud on it . Don't know what a sound difference it would make but I thought I should let you know in case someone else might have a theory on it.

Hope this helps.

 

Sounds about right. If you think it is loud now, wait until winter time when it is pulling cool dense air through it.

Mine seemed to get a bit quieter with time too....I was wondering about that or if I just got used to it.

 

Yes those definitely whistle. My wife hated it

 

yeah i love it so far its definately unusual, i have the ais kit on it and cut some holes through it to breathe better this one is brand new so i know it should last as far as a cool down time is that required or what do you guys do?

 

I usually let it get below 400*, however long that takes.

 

ok well i dont have a egt gauge yet i need to get one i ordered a scangauge i wonder it has a accessory that would work with it

I rode in Robins (PaysonPSD) this evening in Flagstaff,and to me it sounded like a police siren...lol. He put it in the 120 tune and womped on it and it was hold on for the ride!!!

 

Yup mine sounds about the same, when I first put it in I found myself looking in the rearview, one because I had to hear it a WOT and two it sounded like a siren. It has gotten more quiet over the miles but I would do it again.
