So what does everyone think about the new BorgWarner turbos? I tried to bring this up with my last thread but no one visited that one.

BorgWarner Turbos

 

the r-85 turbo kits use borg warner turbos and i like my r-85. also check out TEC turbos same thing

 

They are decent turbos on par(quality wise) with master power turbos and not like the cheap chinese knock-offs.

 

^^^^^^
Same here

 

WHOAA!! Dont' compare Borg Warner Turbos with Master Power turbos. BW turbos are OEM replacements for many different applications. They are on the same level of quality as Garrett Brand turbos.

The BW lineup that most of the performance market is interested in is the "S" lineup. The "S" lineup has two big technological advantages. The first is the Map width enhancement groove and the second is the Extended Tip Technology.

You can read more at www.bullseyepower.com (right hand side)

 

I've read about that, has anyone actually used them? and how do you feed the map width enhancement grooves?

 

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.

 

Here is a pic of an S200 compressor wheel. If you look closely at the wall of the inlet you can see a groove slightly below the top edge of the compressor fins.

 

The "map width enhancement groove" is NOT a "big technological advantage" (at least to probly the majority of applications), nore is it new technology, and nore is it exclusive to Borg Warner. Its a simple ported shroud, it makes a cool sound, other wise useless on most performance applications other then diesel engines.

Some of the Early BW turbo's were Garrett clones and used for OEM applications (Schwitzer). Schwitzer and KKK merged under Borg Warner. They still do sell Garrett clones although now they seem to have come up with a lot more of their own proprietary stuff along with KKK and Schwitzer technology all bleanded. Quality stuff none the less. They are the only company I've seen using the extended tip technology and offer to titanium compressor wheels to the public.

Mike you are correct that the MWE has been around for awhile. I was just stating that ALL the "S" lineup uses that. Holset uses the MWE on most of there turbos too and you can get it as an option on some Garrett units.

 

Looks like I'm using an "s361" according to there website.

 

you bought it from ron so it must be junk

 

The BW turbos are of good quality, as per 1st hand experience nearly 2 years ago before anyone in the rotary community had probably seen one. But dont knock the MP turbos either on my old poorly put together set up I did 480rwhp@19-20psi with the MP t70

 

im having some problems with the websites information i have the ht-300 schwitzer turbo from TEC turbo and the map they have on thier site is the sme map that the above websites are claiming are the new s line 300,330,363 or whatever # they are using is this a typo or something?

also the power that is lised on there sites is piston powered cars as BLitzed33 has just maxed out his borg warner 300 @ 27psi and id got mid 500whp

 

I know it wasn't $1,299, that for sure.

Hmm I just realised I have a better warranty too.

Don't these comp specs look familiar? I Don't have a pic of my comp wheel handy at the moment.

The TEC units are Borg-Warner units.


There are just alot more compressor wheels and turbine housings available now. Most places before could choose from S359 & S361 or S471 & S475 These are off the shelf units that have limited choices on turbine housing a/r's.

Now there are S362, S364, S366 with T3 and T4 flange options and then the S400 line up (S465Ti, S471, S475, S480) with more turbine options then the 1.32 that most people have ended using.

This amount of choices that are now available will allow these turbos to be customized to what the end user needs.

 

Are you a dealer? If so, could you shoot me a PM.

Thanks!

 

Send you a pm about what?

 

I do modifications for the GROOVE, seems everybody likes the sound, I dont think improves performance much, HEY! for about 5yrs now, they send me there turbo and I make into a ported shroud turbo, 1st one was on my FC, when I was cruisin around Daytona guys would ask what makes that cool spoolup sound, then asked if I could do it to there turbo, done about 7-8 of them , $ 400 is expensive but depends on the person, some want performance and some just want to be different a little show off, thats cool too! anyway after some experience doin it, I now can make them loud or soft. it is said they can reduce surging, but aint got no proof of that on rotarys. there is a couple of things I dont like about ported housings but i will leave that to another day!! THX RON

 

Supposedly the ported shroud will decrease compressor efficiency slightly and lead to a bit of lag. Any comments ron?

 

With very large compressors/wheels that's seems to be agreed among by many.
The way in which HKS/Garrett did the TO4Z compressor housing seems to help with the lost of inlet flow but still has the anti-surge present.
Now is the anti-surge slots there for function or just the cool noise that it makes is another story.
I've personaly seen where the anti-surge housings stopped the turbo from being driven into heavy surge from too much boost at very low rpms but I've also seen where it did not make a difference. I guess it's application dependant.

 

Thanks for the info Crispeed. I've heard about anti surge housings creating a bit more lag, but I don't know how much lag we're talking about. Anyone care to comment out of personal experience?

 

Found this on supraforums, seems like the anti-surge will hurt spool up a tad (200 rpms or so) and lead to a few less rwhp:

http://www.supraforums.com/forum/arc.../t-171501.html

<<T78Supra: "I have installed and driven several 67GTQ, 71GTQ, & 74GTQ cars and IMHO the 71 is the way to go hands down.

The 71 spools like a 67 and pulls like a 74.

If you look at its compressor map you will see why. (its huge)

The 71 is a very unique wheel, I'm surprised there haven't been more wheels produced similarly both larger & smaller on a 5 axis CNC.

I have also tried this turbo in both anti surge & standard form, the anti surge spools slower and made less power.

Anti-surge was how much slower and how much less power exactly?

it started spooling at the same rpm but the antisurge takes longer to hit full boost, I would say the antisurge needs another 200 rpm to hit full boost, the standard housing jumps to full boost almost instantly I have never felt a large turbo spool the way that the 71 does with the standard housing.

Our dyno testing showed the standard housing making 15 more rwhp at 28 psi, the testing was done on the same dyno on 2 different days.>>
