I know this topic has been brought up numerous times and I have serached around on here the last few days for information. But I'm just not getting a straight forward answer.

So, I towed a 27' rental travel trailer through Yellowstone last week. And what I noticed was that fluttering sound when going up a hill or even a slight incline. The only way I was able to get this to go away was to downshift. Basically all I did was take it out of overdrive. To me it seems if you are not at the right RPM at least with my truck, I will get that flutterring sound. And when it's doing that, there is a lack of power.

I have nothing special installed in my truck. Pretty much a 6637 and a 4" turbo back that's it. I have no chip, no programmer etc. I keep hearing about installing a WW to help with this. HELP is the key word here. It doesn't sound like this completely fixes the problem. Some have said it did and others said it did nothing but make their turbo even louder.

So, I need the diesel brainiacs to tell me for one, is the WW worth buying when it is not a 100% guaranty to fix the problem, or is this a common problem with our trucks with no solution? This link https://www.ford-trucks.com/forums/1...rbo-surge.html had a lot of what I was talking about but no real resolution to the problem. Some help on this would be great.

 

My experience is, i've had the w.w. in both my turbos, and it cured the surge completely. I dont have the funds to do the ATS housing, or i would, or better yet, i would just do a van turbo, but i'm restricted.

 

^^^ agreed... I installed a ww in my truck and my buddy put one in his too... Now neither one of us can make our turbos surge, no matter how hard we have tried to push them to do so. Pretty happy with the results so far.

 

So, how many of you guys have put the WW in yourself? And how big of a pain in the a$$ is this job? Is there only one way to do it, or is there several ways being that one of them is the easiest?

 

Just curious...but I'm surprised the stock set up and turbo produces enough boost to cause surge. Would have thought the system would de-fuel at 22-ish psi, and that surge is more of 25-ish psi problem... Just curious...

 

Some of us, like myself are running an overboost fooler of some sort, so no defueling at 22 psi. However, to answer your question a little bit, I used to get surge around 15-20psi when towing my fifth wheel. only got surge onloaded if I went WOT getting on the freeway or something and that surge wouldn't show up until around 25-30 psi

 

...which is what I find curious. If it is pressure dependent, as I've always assumed, why does it care if it is "loaded" or "unloaded?"

What weighs more, a pound of feathers or a pound of bricks...that sort of thing.

 

According to my gauge, i was surging around 12/13psi.

First way i removed the stocker and installed the w.w., was with an impact/15-16mm deep. But i found out after, when turbo popped, that the w.w. wasnt "seated" correctly on the shaft. There should be about 3/16-1/4in of shaft, protruding thru the wheel. That wasnt the case for me. The second one i installed, the turbo was already out (chasing a harmonic sound which ended up being the trans), anyway, turbo on bench, grabbed the new w.w., and installed that way, threading in on hand-tight, to "clean" the w.w. threads, then re-torqued it.

If you dont want to remove turbo and do the impact way, i'd say do yuorself the favor, dump the downpipe so you can access the exhaust wheel, jam a duct-taped up screwdriver handle, into it, then thread w.w. on with ur hands, then finish it with impact, with light shots of gun, remove the screwdriver then blast away with gun, til seated.

 

I have surge when towing my 5th wheel. That is the only time it I notice it. Not saying it's not there, just more prominant when towing the 5th wheel. Don't even notice it when towing the gooseneck trailer loaded with hay, or the tractor. I have wanted to try a ww, but have been hesitant to spend the $ for a new one, if it doesn't help. I just kick off the o/d. like stated above, get the rpms up and I don't hear it then.
