It doesn't look like one to me

Mine is an S-480 w/ a race cover, and that's what mine looks like. Measure the inlet: if it's 5-1/2" it's a race cover. Also I think the non-race covers have the v-band connection.

Yes, its a race cover. It has to be a slip-on outlet to be a race cover.

Ok answer this, what besides the one thing that has been pointed out makes it a race cover

That's not a race cover, that's the standard cover I had before. Here's my race cover...

This says its a race cover, same part number on the compressor

Mine doesn't have a race cover(76mm)but look how the surge ports have been machined. They are more than double the size than the OP's pic. I also think there are many different versions of race covers. I find it hard to believe this years race cover is the same as 2 years ago.

Just to throw this out there...

Why do larger surge ports make it a race cover? Why would larger surge ports aid in performance? I was under the impression air wasn't being "sucked in" the surge port area in boost. Thought the scroll itself was larger in the "race covers", no?

The race cover has a velocity stack machined into the cover to allow a wider range of air being pulled in. The "straight cut" housing is standard. If they say that version is a race cover then I would question it.

If that's the case couldn't I just tack weld a velocity stack on my "non-race" inlet? (center portion only) And have a "race cover" ?

In theory I guess so, lol. When people put them on carbs all they do it bolt them around the inlet like you would a air filter.

The compressor housing you have on your turbo isnt even a Borg Warner compressor housing. Its Made by Bullseye.

OP yes That is a race cover.

LilJohn

the Borg Warner Symbol cast into the cover up there by the outlet... The RC has about a 1/4 inch bigger overall diameter than a standard cover. Different part number cast onto the housing. If the cover is as delivered from Borg Warner it will have an inlet bell in the opening.... but the good shops that know that turbo remove it... The turbo flows more air without it.

LilJohn

No. The 3 inch slip fit outlet and the differences in the inlet are the 2 most minor differences between the covers. What your proposing would more than likely hurt the performance of your turbo. There are differences inside the covers that you cant see that makes the race cover better than the standard one.

You are correct, it's a Bullseye cover, however through all my research looking to buy, all the "race cover" turbos has a cover that looks pretty close to mine. I'm sure there's more technical differences but this is from my research.

That makes sense at least... thanks...

When I was sent my turbo it had a non-race cover on it (I ordered it with a race cover) when I was sent the race cover I took several pictures of them side by side. See below

My race cover came with the inlet bell. How do I remove it. It looks like it is pinned in place on the compressor inlet.

OP, that looks like a race cover to me. Here is my race cover on a S475/83:
