ok i just thought we should talk about these turbos cause i just noticed these not too long ago and feel like i dont know a damn thing about them and no ones bought it up. anyways does anyone have any feedback on these

TTT

The Borg Warner "S" lineup ROCKS!! The spool great and have great top end performance too. The S256 is a killer street turbo. It has put down 445whp@21psi and 550whp@30psi and if that is not enough you can set up to the S300 lineup which can support up to 900hp.

Borg-Warner also have the standard turbos too.. 47 trims, 57 trims, 60-1. These turbos are OEM replacment turbos for many applications so the are reliable and also from Bullseyepower the T04B and T04E lineup come with a 1 yr warranty.

Borg-Warner has just recently official come into the performance market. This is because of the relationship the have with Bullseye Power.

There are many race teams that are running BW units now. Vinny Ten, Brent Rau, Paridise Racing, AAP Motorsports, Matco Tools Chevy Cobalt, Dee Karagiannis. They are the newest secret in the Pro racing world. There are a few more race teams that will be running BW/BEP units next year they are just not offical yet.

what do they have that directly compares to the gt40r and gt42r from garrett? especially the 42r that will make a legitimate 800whp on a b series on a dynojet.

TTT

Ok. I will try to cross reference what BW units are the same physical size as some of the GT units:

GT4082 (58lbs/min)= S258 (60lbs/min) or S362 65lbs/min (slightly bigger, but close)

GT4088 (70lbs/min)= S366 80lbs/min

GT4294 (85lbs/min)= S471 90lbs/min

GT4202R (100lbs/min)= S475 110lbs/min

All the BW units have their Extended Tip Technology and a Map Width Enhancement Groove.

Hopefully this helps some.

I saw a post on them on Supraforums. Apparently they kick ***.

Boostfed

I will be dyno testing a Borg Warner S366 against a GT4088R and also a GT4067R in about two weeks once I do I will post results up. Here are specs of each turbo BTW that I will be testing

GT4088R= inducer 63.5mm exducer 88mm turbine housing 1.06 A/R divided
turbine wheel 77mm and 73 trim

GT4067R= inducer 66.5mm exducer 84mm turbine housing .81 A/R undivided(I wish I could get a divided) turbine wheel 77mm and 73 trim

S366= 66mm inducer 91mm exducer and 96mm with the extended tip turbine housing will be a .83 A/R divided 79.756 inch inducer and 70.866 exducer 79 trim Turbo flows 80lbs/min

yea they seem to kick *** from what i hear and they look amazing. i might have to pick one of these up for my self but i dont think i'll need one that big. i'll stick with my t3/t4 cause im only lookin at making 300-350whp

by the way thanks for the info, this will bring more interest to the turbos and help open up new doors for some people i guess

Absolutely

Kelly.

i was looking at thier site,

and the little bit i know about compressor maps, it looks like these turbos are still efficent at higher psi levels

im running my t3t4e 57 trim at 28 psi and i think im pushing it out of its efficency range;
would a BW turbo be something i could use?
i saw the s256, and it seems like a 60 (ish) trim that can spin alot higher then the garret version.

Talk to TheShodan about them also. I believe he is a direct dealer for them... and he is all about customizing them per setup.

What did you use as the comparison criteria?

What is "a Map Width Enhancement Groove?" I haven't heard that term before?

xfrankx

what turbo do they offer thats comprable to a garrett gt35?

i plan on going with that turbo unless they sell one thats about the same for a good price

the people at bulls eye have been great to deal with me and boostfed will both be dynoing the borg-warner turbos very soon to give the public real results. terry will supply the dyno charts and ill tell you how they work going down the track . if any body has serious questions call bulls eye and ask for dan really good guy to talk to 1-877-784-0379

I matched up the Inducer sizes of the compressor wheels to compare them.

Here is a pic for the compressor cover:



You can see if you look at the top of the compressor wheel. You can just see the Map Width Enhancement Groove. This helps to fatten out the compressor map which fattens out the islands of effiency. Which allows the turbo to work more efficently over a broader range of pressure ratios and flow.

The S200s line up is comparable to the GT35Rs. There are the two compressor wheels for the S200 the 56mm and the 58mm.

ok i dont think im gonna get a turbo as big as the s200 or g35r but i was gonna stick with t3/t4 area. i just recently sold my turboentics turbo and looking at buying a new one which i've been looking in to these borg warner turbos. trying to decide between one of their turbos with the precision sc61. im only looking for like 300-350whp should i go bigger?

TTT

The S200 would work great if you wanted to grow into. It has such a broad range that it can work on so it is happy to make 350hp just well at 550hp.

If all you want is 300-350whp you would have you look at either a 50 trim (made 320whp@12psi on a B18 GSR two weeks ago) or a 57 trim will take you a little higher

Do they offer anything in a divided t3 housing, that is ball bearing and capable of 700hp, with a 4 bolt or v-band discharge?

.76 A/R and .85 A/R divided T3 available in S200 and S300 turbos sir. Sorry none of the turbos are ball bearing, if you want 700whp then the S364 or S366 would be the ticket LEANING more towards the S366 though

Here's what I posted over on supraforums. I'm very interested in seeing the differences in spool and power between two virtually identical turbos (as far as inducer and exducer diameters).

"How about the GT4082 versus Borg Warner part number 167338. It has a 59mm compressor inducer and a 67mm turbine exducer. These two turbos are virtually identical in every wheel size. That would be a great comparison since neither would have any sizing benefits or benefit due to ball bearings. The GT4082 seems to be a great cheaper street turbo for the MKIV also.

A GT4088R and Borg Warner 169417 also seem to be fairly close in overall sizing, though the difference in bearing type and 2mm turbine difference + 2mm compressor inducer difference might not make things as close as the previous comparison."

Bullseye Power does not use this compressor wheel in any of their performance applications.

The S258 is really as close as you can get to the GT4082 the S258 will have a smaller turbine wheel then the GT4082.

timg

Hmm... Where can I find their compressor maps and wheel specs on their performance turbos? I'd love to see some of that for the Holset turbos as well. I've searched every website that I've found. I saw the Borg Warner catalog that lists a few different turbos (not the 362, 364, or 366 as far as I can tell). I've also seen a single compressor map that seems to be used for every S300... I'm interested in a full T4 sized replacement and figure that I might as well look at all of my options. Thanks.

Tim

The compressor maps for the specific performance wheels are not available to the general public. I did happen to see a hard copy of the s366 compressor map last time I was at Bullseye. It was a good looking map. not that me saying that makes much difference. Plan and simple the BW maps are are kept secret like the Holset ones.
