Re: s cover vs. e cover (ScottEK)
From everything I've seen - it just depends on the wheel in there. Some wheels will like the S cover, while some will like the E cover more.
I know the 60-1 wheel is slightly more efficient in the E cover versus the S cover.

Re: s cover vs. e cover (Arturbo)
i beleive they are talking about the housing....imo the main reson people would go w/a smaller housing is for size/spacing issues.....I would assume the larger housing is going to flow more

I've heard the other way around but I have not seen proof of this.
Ive seen same hp on set ups that are the same, but Ive never seen a back to back test done. hmm, this could be something to test on the engine dyno.

Re: s cover vs. e cover (Arturbo)
Saw this in another thread....
<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by Rod Short »</TD></TR><TR><TD CLASS="quote">
The SC63 is actually more expensive than the SC61, but not a lot more powerful. We rate the SC63 at 700-hp, which is only twenty more than the biggest SC61. By the time you add an S style compressor cover (4" inlet / 2.5" outlet), you already picked up 10 to 15 hp, which would put you just about there. The SC61 has a much more efficient compressor wheel.</TD></TR></TABLE>
That goes along with what I've always heard about larger a/r comp housings.
