Does the 38R turbo have a "whine" or some type of noise at highway speeds when towing? How does it compare to the van turbo?

It has a whine when it spools up and at certain rpms.

It's sounds very different than the van turbo

Is the sound it makes disturbing and an annoyance on long trips when towing?

Depends on the intake you are running. When I ran the 38R with a 6637 intake, it drove me nuts over long distances at a constant RPM. I now run the S&B enclosed intake and it makes it much more manageable.

The van turbo isn't louder than stock

What other parts should an individual buy to go with/accommodate the van turbo?

You will want the outlet flange. It is different than the stock turbo.

I would also get a Billet compressor wheel.

Careful with the van turbo though. It has a 1.15 exhaust housing which will make the turbo a little more laggy. It does good in the upper RPM band though.

I've found that with tuning and a billet comp wheel they spool pretty fast.

The turbine wheel is larger on a van turbo as well.

They are not laggy like a D66 turbo, but still more-so than a stock SD turbo with a .84 housing. They were a non-wastegated design, so to get drive pressures in check, a later spool is the norm.

Wife & I tow a travel trailer, sometimes long distances, so quietness is golden for us.

Under a load at 1800-2000 RPMs, is the whine/noise of the 38R noticeable? Thanks in advance

If you don't like to turn the radio up, a 38R may not be the best choice for you then.

I run one, and have pretty much gotten used to it singing. If I don't want to hear it, I turn the music up.

Do not usually play the radio when towing. Perhaps the van turbo or another stock turbo might be a better option for us when the time comes for replacement.

You can do that. Another option is to use a billet wheel in the GTP38R. This quiets it down a bit. The downside is that the 38R does not perform as well with a billet wheel compared to the stock cast wheel. So you are decreasing sound, but losing performance too. I opted to deal with the sound.

Thought I would bring this thread back since I started it many years ago. On the new 38R turbos manufactured now, are they still noisy or have a whistle/whine sound at highway speeds towing? Would appreciate hearing from someone who has bought and installed a new one.

If looking at changing (if new ones are quite, which I doubt) why wouldn't you just go to a better platform?

I have one in mine. I don't really hear much of a difference but my wife says the spool up is a little more pronounced than the stock one. I have bad hearing due to many years of construction noise. But I don't think it will bother you much. I run the AIS intake on mine so that may suppress the sound some.
