.63 a/r housing is the v-band discharge and .66 a/r housing is the slip cover. They are both considered "race covers" from what I gathered. The standard s400 cover is smaller IIRC.

I believe the 4" slip covers are the same as the vband cover, those are both standard covers.

The .66 a/r covers are 3" slip.

Missed the "4 in" part:doh:
 
Do you have a cam Rollin'? I know once I added my PDR to my combo it gave me about 200-300rpm sooner spool and it spooled up harder to boot. I loved my S465 on the street for just driving and rippin' around, only reason I am switchin' setups is to tow and bring my powerband down lower in the RPM's.

Like Dan answered the 0.63 is available 4" slip and v-band and is the std cover, the 0.66 "race" cover is available in 3" slip or v-band depending on your set up.

Unless you just have to have the slip fit I would go with the vband. With the snedge practically giving the cummins elbows away, it takes care of one more spot to blow a boot.

The drawback is unless you get a race cover that has a vband(not available from borg) you have to weld a flange on the end of the BW unit.

ED and Bullseye have the vband race covers.
 
I have the 4" slip standard cover.

I dont have a cam yet, I'm planning on a big stick this winter, also am milling the intake off the head and doing some port work.

I'm going to stick with the s400, and I think im going to go with the 66mm wheel.

Chris, do you have exducers and flow specs for the 65, 66, and 68mm ETT wheels?
 
My Turbo is a large frame Turbo 71mm billet comp wheel and a 74mm 12 blade turbine, and flows 90 something pound per minute
