E cover has a 3" inlet. S cover has 4" inlet and cost 100 more. They say 10% increase in power with the S cover. Search for sc61 and you'll see alot of dyno numbers.

The E can support more boost, the S is "supposed" to make more power. We havn't really seen any gains w/ the S housing and the we have seen nothing but good results w/ the E.

It seems as though the S housing has turned into the bastard step child lately now that everyone and their mother is running the SC61 w/ E housing. I wish someone could really test the two of them so we could see lag and power differences. Maybe I'll buy it just so we can do it.

It does make the turbo seem "bigger"...
I can't remember who it was (tony1, boostedhybrid,...??) but they have also said that the HP difference between the housings is miniscule at best.
I would assume however, that the S housing is less restrictive on the large GT wheel at very high boost (25+) compared to the E housing.

people already tested them and the S made no extra power....stick with the E

What about on a 6 cylinder? VR6?

Re: Difference with SC61's T04E & T04S? (Day Walker)
Lemme ramble a little bit about A/R of a housing.
The AR is a measurement of the Area(the tube inside the housing) divided by the Radius(distance from center of tube to the turbine shaft). Basically A/R tells u the size and shape of the housing and how restrictive it will be against flow. Its easy to understand how that works on the exhaust side; a smaller A/R will spool faster but it will flow less air. The compressor side is basically the same; except now you want to compress the air. We all know what pressure is right? Resistance to flow. what does a smaller a/r do? Restricts flow. The smaller A/R on the compresssor housing will create boost pressure w/ less compressor wheel speeds then the larger A/R. However, a larger A/R will flow a larger volume of air at the same boost pressure.
Choosing the right housing really comes down to the compressor wheels efficiency range. Think of a compressor map for a specific wheel, notice at a specific boost pressure how many lb/min the wheel flows. Now look where the efficiency island sits. The different A/R housings are basically going to move that island left/right/up/down for a specific wheel. The S housing will basically move the efficiency island down/right and the E housing moves it left/up.
What does all this mean? its a bunch of technical bable that really doesn't matter. The E housing works great and until we do a back to back comparison of the E vs. S its purely opinion on which one makes more power for our applications.
I think one reason alot of people think the S automatically makes more power is because on the 60-1 turbo it does. With the 60-1 compressor wheel the S housing just happens to be the right combination. I am not so sure yet about the SC61.

if garret outfits the turbo's with S housing's thats gotta mean something
or it could be to just drive the price up by $100

Re: Difference with SC61's T04E & T04S? (SiRkid)
hehe your probably right.
and for GOLDBERG - show me the dynos . . . I've never seen any any.
I remember tony1 tested the SC61 VS the SC63, but if I remember right the 61 hade the S housing and the 63 had the E housing. The 63 yeilded very little power gains when compared. I'm not trying to spread heresay so I'll try to find the post.
