Default steam turbochargers (n55 67mm turbo) - 05-09-2016, 01:39 PM

Hey has anyone heard of this company and if they're any good? (I have pure turbos on my m4, and going to get it on my m235xi, but not on my beater 2011 335i).

Default turbo - 05-09-2016, 01:59 PM

If you go stage 1 turbo. Rather look at Pure or Vargas stage 1. Both are similar in power.

Interesting. Clearly its not as good as the Pure Stage 2 considering the turbofold and its parts aren't modified, but I wonder how it compares to a Pure Stage 1. It is VSR balanced, which give it an advantage over other competitors (though not Pure).

Go pure stage 1, Vargas doesn't offer vsr balancing which is dumb when turbos spin at 100,000+ rpm and hit all sorts of resonance frequencies during that process.

Edit- Pure also has vastly greater customer service, Jesse will take care of you and treat you right!

At that price I would hope that it had a little higher output than Pure's stage 1. Looking at just the inducer it doesn't look to be bigger.

Pure emailed me and said it was equivalent to their stage 1.

I'll go ahead and paste my email reply:

"The link you sent me is similar to our Stg1 turbo. So yes. Our stg2 is much larger than that. The Taiwanese company that makes that turbo (who steam buys it from) copied our stg1 turbo."

However we updated the compressor wheel in our stg1, so that is equivalent in size to our early Stg1 turbo which we don't sell anymore. Oh the overseas copy *** game... So fun, sigh.

Lol!
Ahh, so anyways op go buy the pure stage 1 it's much better and $895 I believe it was, so cheaper and a better performer.

I like knockoffs. But usually they're cheaper. If its more expensive, whats the point? I do like not having a Core charge though and getting to keep my stocker.

First off, this is our first post on the forum, but we are excited to engage with the BMW community. We have been manufacturing Subaru turbos for several years now, but BMW N54, N55, and S55 motors have a ton a potential, so we'd love to continue to invest in product development for them. At our our core, we are an engineering focused company, and generally better engineered products bring about superior results.

Here is a picture of an actual Steam STX 67 for BMW N55.


Our turbo is similar in size to Pure's and Vargas' Stage 1 turbos, so what is the difference?
  • The main difference is that we manufacture all new parts; whereas, Pure and Vargas remanufacture the stock turbo with a bigger compressor wheel.
  • We ship you a new turbo, and that is it. We don't need a core, so you don't have to send us one.
  • We balance or turbos to around 100k RPM on a VSR, which covers at least the 2nd order harmonic of the turbine wheel. It seems crazy to me if others do not do this.
  • We offer a 1 year warranty on our turbo products.
  • In our testing, it appears to make somewhat less low end torque, but make about 20 WHP more peak HP with pump gas than the rebuilt OEM "stage 1" units.

It seems like people have had good luck with Pure's and Vargas' products, so we have no disrespect to them or their products. We are simply confident that our turbos are manufactured to the highest quality, and will work at least as well as their similarly sized turbos.

In the spirit of keeping it real, Borg Warner invented this turbo for BMW, we (Steam, Pure, Vargas) did not. We are all "knocking off" OEM unit.

This is the age old practice of making upgrade stock location turbos along with swapping a small compressor wheel for an updated bigger one. I don't think any of us invented that either.

Machining a compressor housing to support a bigger compressor wheel is not hard. Same for turbine wheels. To be honest, building tooling for new compressor housings is not hard either. Developing tooling for a new high flowing manifold and turbine section is hard.

It took us over a year to develop a design and tooling for the new turbine housing of the 2015 WRX's FA20 DIT twin scroll turbo. We could do the same for the N55 if there is enough interest. We would prefer to manufacture a new turbine section with larger volutes (scrolls) that would more efficiently support a larger turbine wheel (ie A/R). Simply using a bigger turbine wheel in the stock turbine housing is not a great way to efficiently make more power. The A/R is out of whack.

There is no reason a 71mm compressor wheel could not make over 450whp, and a 76mm compressor wheel could not make over 525whp if the turbine section was well matched for the application. This is what kind of power we see on our stock location Subaru STI turbos with their super old port injected EJ257 motors. The larger displacement N55 motors with DI should do even better given the same turbo wheel combinations.

I can make a dyno graph in excel too... This is pretty useless with out a baseline or even knowing what type of dyno this was on.

There really isn't much of a market for the stage 1 turbos. I think your time would be better spent making a stage 2 or bigger. Right now the Pure stage 2 is the only option (until the Hexion gets tested). If you could make something with more potential than the PS2 then you would have a foot in the market.

You forgot VVTs stage 2 option.

I do agree that there isn't much of a market.

Completely agree with the above. Pure is the only choice you want to pick for a stage 2 upgrade at the moment. They also seem to have found the limits of the oem manifold with its small ports.

A redesigned manifold and turbine housing like you mention above in one of your posts would no doubt gain a lot of interest from the community and sounds like it could bridge the gap between stage 2 hybrids and full on stage 3 kits.

Steamspeed, well done on an intelligent, professional response. The big V could stand to learn from your example. Again, well done. That's how you disagree professionally!

Well that would classify as a bigger single turbo or stage3 like you call it. Its the next step after pure stage2.

I believe they were speaking about a stock location turbo meaning you can use the same ********, oem oil connections, turbo inlet pipe, intake etc. however they would re work the turbofold (manifold and turbine housing) to improve flow.

To me a stage 3 or big single turbo kit involves, seperate manifold, turbo in a non stock location whether it's top or bottom mount, different ********, option of a screamer pipe , new oil lines etc. basically a no compromise kit tailored to your needs .

Ah if you look at it that way Yes that would be cool too. Another 100 hp would be nice either way!

Are there any E85 blend HP/TQ numbers on this unit? What would be great would be some JB4 logs! I'll be in the market and doubt I'll go PS2; looking to get into the 430ish range with E85 if need be.

How did the car perform yesterday Peter?
