ATS ported compressor housing - Page 2 - Diesel Forum

deputyzach · 06-20-2009, 08:32 PM

I picked up a compressor housing today and I am going to put it on, on Monday with the stock wheel. (pulling the Wicked Wheel out) I was also wondering if it would be worth doing the 1.0 exhaust housing too. I pull a 30 foot house trailer 10K and my EGT's get up there sometimes. Will the ATS housing and stock wheel get me more air flow thus lowering the EGT's.

7.3 4" turbo back, 6637 DIY and 6 pos TW chip.
TIA

Actual proven claim or just your opinion? I would like to know since my housing+outlet+turbo master+cfm plus' new air intake are arriving this week.

I have the "ww" and it helped a lot, it is louder and I have the stock airfilter box. I like the whistle but I agree that "sometimes" it can get annoying but most of the time is a satisfying noise...lol

Think of it this way.

It takes energy to make noise, and that energy could be put to better use making air instead.

Just a thought.

or maybe the blades are little more aggressive moving more air and that makes it whistle more......regardless, comparing both the WW "looks" like it would move more air, and

wants it to be quieter, of course.......imagine people test driving it and getting "annoyed" by a loud whistle

I've had the ATS housing a couple years now w/ the stock wheel. It whistles loud from 9-12 psi and goes away. I believe the WW has alternating fins reduced in size as a fix for the surge so I don't think it can move as much air as stock.

I'd rather have it quiet than hear that deafening whistle all the time. the 3 psi range is all I need.

i want to keep an eye on this thread

From what I have read the stock wheel gives better low end performance while the ww has eliminated turbo surge on some vehicles and might give more top end HP. I think the ww was stock on pre-99 turbos. I have not seen dyno curves of the two wheel types side by side so my understanding is gleaned from what has been discussed here and on other sites.

A dyno curve would help a lot !!! Anybody?

**PowerstrokeConverters** · 06-30-2009, 06:17 PM

I am not sure if they actually got the thing on a dyno since it does not show it, BUT, it might be true, so here it is, you can go to the last seconds to see the claim or just watch in its entirely I guess...

YouTube - Wicked Wheel Install

Now, where the heck did I put my stock one LOLOL

nice video, you guys probably seen it, at 1:47 sounds like mine when I get on it....that very high pitch whine...first day I heard that I thought I had a bad leak or something, it was after the WW was installed, anyways watch it and enjoy those that drive the beautiful 7.3's :YouTube - 7.3 Powerstroke with 38R and 1.15 exhaust housing

The way the WW gets rigde of surge is by moving less air. I had the WW on my 01 to fix the turbo surge. I have 4" turbo back, 6637 intake and dp tuner and empty I would have turbo surge the wheel fixed it but my EGT's where higher 75-100+. Just this past week I put the ATS ported housing housing and stock wheel back in it and pulled 11K, 600 miles west across windy NE at 80 mph with no surge at all and my EGT's were steady on 900-975 depending on grade and wind gust. I still plan on doing the 1.0 exhaust housing to bring the temps down a little more.
Any body that needs a WW I have one for sale.

**PowerstrokeConverters** · 07-01-2009, 09:42 PM

Nice to see that ATS makes a difference, I just wish I had all of that I have now when I towed 3 cars plus trailer over 2800 miles driving 14 hour days. I could not be happier and more proud of this beautiful tuff 7.3 powerhouse, I remember how it screamed up and down the grades in Virginia on cruise control LOL
Thinking back I would probably take it easier if I had to do it again.

But it performed beyond my wildest dreams and expectations, no matter what they say about 6.0's or 6.4's, cubic inch and simplicity still rules.

So that begs the question, how does the ported shroud work? From what I've read it has a "bleeder ring" built into the housing so that it has a pressure relief. What's to stop the air bleed from reducing compression when you don't want it to. Could it be that the ported shroud reduces HP ?

If someone who has one or is knowledgable on the air flow dynamics can chime in that would be great.

Probably the biggest improvement is the 4" inlet. The factory turbo has a 3" which is ok with stock tuning and the stock airbox. But when a intake system or BHAF is put in it allows beter flow to the compressor. Then you throw in tuning that allows more fuel which requires more air. The 3" inlet becomes the restrictor to the airflow, that is why the WW reduces surge. It is actually less effecient due to the staggered blades. Surge is really cavitation.

BTBBT · 07-02-2009, 10:46 PM

Have you seen the ATS housing, it may have the 4" inlet, but the area that the inlet to the turbo, is no bigger. that extra .5" around the outside is part of the bleeder ring thing.

woodnthings8 · 07-03-2009, 12:10 AM

A 3" inlet has just over 7 sqin of area. A 4" has 12.5 sqin of area. That probably makes the difference. Just having the stock inlet tube neck down from 4" to 3" creates the air to increase pressure as it gets sucked into the wheel. I plan on buying the compressor housing soon, because most everyone says it will eliminate surge without boost loss.
