see title? i think it probably would be (FC or FD aplication), it would probably be more suited around 500whp IMO by looking at the compressor map.

 

It absolutely is. You're giving away low end boost response and spool up for no good reason. If you're sticking with BW, an S362 is much better suited to your goal. Hell, a good friend has been making 480 rwhp on an S362 at 20 psi for like 7 years now.

 

Goodfellas is right on the money.

unless you are looking to make over 600 hp or go w the EFR subset BWs can be as easy as

A B C.

A is the smallest and has about a zillion tags. it is most often referred to as the S362... (even though the inducer is 60 mm)

P/N 177272 features a conventional directed output nozzle while 177280 has a 90 degree bend.

here's the compressor map, thanks to Full-Race



B is mid range 177283 (90 degree)



C is the S366 177284 90 degree, 177281 & 177275 straight




there are few free lunches w turbos.

A compressor wheel is 6.437 average sq inches area

B is 7.06 sq inches

C is 7.74 sq inches

as area increases so does the power needed to drive the wheel/lag

and, generally, so does flow.



comparing the compressor maps.....

.................................................. pounds per minute/apporx max rotary rw hp


boost...................14.7...................... .....20..................................max

A......................58/437.........................69/482...........................68/512

B......................64/482.........................69/520...........................76/573

C......................66/497.........................71/535...........................77/580


"has been making 480 rwhp on an S362 at 20 psi"

notice how neatly Goodfellas friend making 480 at 20 fits the compressor map derived number.

as you can see, turbos B and C don't fit your objectives.

nice!

i haven't seen much of the bw turbos in the past until on of my friends put a bw s400 series on his infamous black supra and it got me interested.

 

I.always.called.my bw 177272 a s360... but.its also known as a s362?

 

Yep same...S360 does not have a 62mm inducer...
- S360 (aka 8375): 60mm inducer
- S362/S363 (8875): 63mm inducer
- S366 (aka 9180): 66mm inducer

Then you have the billet wheel S300 frame turbo
- S362 FMW (aka S300SX FMW): 61.4mm inducer (billet compressor wheel)

 

Ok, so I have a 63mm(~62.8mm) compressor wheel and not a 60 with a 1.00A/R divided. The above chart I believe doesn't cover the same flow for?

 

"I have a 63mm(~62.8mm) compressor wheel and not a 60 with a 1.00A/R divided. The above chart I believe doesn't cover the same flow for?"

as i have consistently posted, there are a lot of variations and labels in the BW line.... not really a bad thing.

as to your question... you have the "B" turbo.


"- S360 (aka 8375): 60mm inducer
- S362/S363 (8875): 63mm inducer
- S366 (aka 9180): 66mm inducer"

8375 comp is 60 X 83.75
S362/363 can be diff turbos depending on who is doing the tagging.

"362" can have a 60 inducer
"363" has 63 inducer as does 8875, o k, some list it at 62.99 (PN 177283)
"S366" is tagged by some as the 9180 but should not be confused w the EFR 9180

while the compressors are close as to dimension they are quite diff as to output w the EFR making 10 pounds more air top end at significantly greater efficiency.

Personally, I don't like using Borg Warner part numbers to describe their turbos because they are very compressor/turbine housing specific. For example, the following two turbos have the exact same compressor and turbine wheel specs but different compressor and turbine housing styles.

Borg Warner P/N: 177272
Compressor: straight outlet housing, 60mm inducer, 83.5mm exducer
Turbine: 0.91 A/R divided T4 housing, 76.2mm inducer, 67.5mm exducer

Borg Warner P/N: 177280
Compressor: 90-degree outlet housing, 60mm inducer, 83.5mm exducer
Turbine: 0.88 A/R undivided T4 housing, 76.2mm inducer, 67.5mm exducer

Can you point me towards a 60mm inducer BW turbo that people refer to as S362? I can't seem to find one.

I think this just has to do with rounding. The S362 FMW (S300SX FMW) actually has a 61.44mm inducer, but some people say 61.4 and some people try and call it 62mm to align with the S362 FMW name. This is why I usually like to refer to it as the S300SX FMW rather than S362 FMW.

Agreed...as if BW turbos weren't confusing enough.

 

Like howard said...your turbo is the "B" turbo that he listed the flows for.

 

just following the naming setup wouldnt a 60mm inducer be a s360?

 

well looks that i may have overshot my goals withe the s366, or at least i have on this stock motor.

but ill be getting tuned this weekend on low boost. i was mainly looking for low boost big power.

 

Lol. You just think low boost.... We are not stopping until 500hp!

 

Whats low boost for you?

My car got tuned with the S366 on a Mustang dyno, was able to push 497 @19 psi and 592 hp @ 28 psi.

 

hellz yeah, any aux injection? race gas? pump gas? corn fed?

 

93 octane alone = low boost

so 12ish psi. so if it makes 400h id be overly happy.

 

93 oct @19 psi
C16 @ 28 psi

No AI

But if you planning to run less than 18-19 psi , I would highly recommend the smaller S362

 

Yes...I would say so at least.
