Anyone know what a borgwarner race cover looks like
Been looking online and cant find what they even look like never mind any graphs to see a difference, just wondered if anyone had seen them, whether they are bigger/smaller than standard etc

Actually this is how it looks like.....
The inlet on the race cover is 5.5" and the cover clearly has Borg Warner written on it with the logo above the writing. The outlet does not taper out either.... it remains the same size

actually, it depends on which turbo you have. that "taper" out is called a v-band. some very large turbo's use this as a connection instead of a coupler. i promise you the pic i posted is a race cover. (hint: bullseye) hahahahaha
the above posted pics by "olyrx7" appear to be a standard cover. but what do i know...

My turbo is the S372, I compared it with both the regular cover(with a v-band connection) and with the aparent race cover in my photo. The race cover was much larger when compared side by side it also had the 5.5" inlet.
I understand all about the v-band connection, so maybe you could clarify it for everyone as to which is which because it seems to get confusing...

you see how the anti-surge in my pic has been smoothed over? it is still there, just not as obvious. thats the dead give away. the race cover is also larger and supposedly "flows" better. to be honest it isnt worth the extra $300. only reason i got it is im a dealer and they wanted me to have the special cover for my shop car.
also, mine is an S475

the first pic is the newer style race cover, the second the older style.
the newer style supposedly has 80hp extra on top..
but it sounds sick, similar to an t51r from what i've read; high pitched whistling.

thanks very much for all your help guys, im looking to order a s475 with a 83mm rear 1.1 A/R and wanted to know if the cover was larger or smaller because of fitment, its pretty tight looking on other builds and wondered if it was smaller it might help and if it made more power it would be worth it.
ill stick with a stock cover then as they seem pretty cheap from forced inductions at $599, though they are crap at answering emails so havent ordered one yet

Scorpion T- Thank you for clarifying about the race covers as it gets confusing for everyone due to the Borg Warner and Bullseye setups.....

Please update Olyrx7, Because Im am also been the 372 or 74 but can't decide. What are your hp goals and what spool up times are you expecting?

id imagine that you could hit 600bhp on big boost with that turbo if you pushed it.
what sort of port have you got as that will effect your spool times and maybe we can give you an idea

I was also stuck between the two but decided that the 72mm will be plenty. I compared the S372 inducer and exducer to my T88H and its night and day lol. The Greddy made 654@29psi, so my goal is to get between 660-680whp@26psi on the S372 I hear thats when it starts to work well....

Im going to be running an extended street port. Custom divided manifold, GL LIM, Ported UIM and Im thinking about going with one of those single bladed throttle bodies https://www.rx7club.com/attachment.p...3&d=1260589146.
Im also running a water to air setup so, piping is short...
and yes... this is a street car

Also, my mistake on the turbo, its a s474/s472 with a T4 foot print that I was looking at... Honestly I think they are the same.
What rear A/R are you using?

Depends on who you ask. Basically the S3xx is T4 frame, S4xx is T4 or T6 frame. Some use the turbine wheel to differentiate.

I dont think I want to go that big.. I do want to go to something that will spool quicker but has a decent top end. We dont have highways here, high ways runs are out, but we do have a drag strip .
I guess we'll have to wait to see what your spool characteristics are.
