On pre -order but it's actually finally coming.

http://https://frankenturbo.com/FrankenTurbo-F55-for-BMW-EWG-N55-p543440859

I'm surprised there is no marketing blurb, isn't it meant to be unique?

Better flowing manifold and lower EWG's?

What's the ceramic coat option pertain to, an internal lining?
What would benefits be.

Is this a stage 1.5 or more like a 2?

What will spool be like.

Experts weigh in!

There's a lot of discussion on their FB group but nothing is proven yet.

Better flowing manifold and lower EWG's?
Yes, the manifold is unique and flows more that the other options out there.

What's the ceramic coat option pertain to, an internal lining?
What would benefits be.
Its a coating on the manifold to keep temps down.

Is this a stage 1.5 or more like a 2?
This is supposed be a stage 3 turbo similar to the pure 750

What will spool be like.
They claim spool to be similar to a PS2 so 3700-3900 RPM

If you're looking for stock like spool, check out the Shuenk N55+. It's a 1.5 turbo capable of about 500WHP on ethanol.

Did any forum members ever post Dynojet numbers and logs with the N55+ and ethanol?

Not that I have seen. Most of the guys on the facebook group are E series owners.

[3t3p]

Ah that's the product I was thinking of and got it confused with the F55 announcement.

The N55+ also has higher flowing turbofold? (if that's what it's called?!).

It would be like the pure 500 and a bit above dinan big turbo?

Installation looks more involved however than straight drop in nature of Dinan?

Piece of info by searching and asking a guy on their FB group, N55+ turbo and M235, Dorch stage 2 hpfp, stock lpfp. Looking good. Hitting 20+psi boost@3500rpm, and carrying to redline. 7k miles already no issue.
And it looks like he's running another revision street aggressive map hitting 25psi for torque. 0.0#

Only log I could find:

Interesting. Only 25whp more than my TTE460, Dorch Stage 1, and E50.

Me either and this is true for most of our M235i power goals. Pure500 or the shuenk N55+ Dinan turbo and even the pure stage2 is sufficient.

That's impressive indeed but the pure500 should be able to do the same. The pure 500 is probably more reliable option plus it's cheaper. PURE is tried and true going to pull the trigger on pure 500.

Full e85 should get similar numbers?

There's no way pure 500 will be able to do the same. The pure 500 is the old ps1 with a modified (likely clipped or a reprofiled design, they say it is larger but I don't see how that's possible without porting the exhaust manifold larger which they don't specify is required so likely you don't have to do it and thus there is no way the turbine can be bigger) exhaust turbine. Other than that the factory turbo fold remains the same. This will likely mean it will be able to flow more at the top end compared to the old ps1 and perform similarly to the TTE460 which also has a modified (and likely clipped) exhaust turbine.

But neither of these turbos will likely be able to flow enough exhaust gas to hold 20psi + to redline, especially not with the stock exhaust manifold and the tiny turbine wheel.

In terms of reliability how do you know the pure 500 will be more reliable than the n55+ there is no data to back this assumption up. Firstly the old pure turbos (ps1 and ps2) were so reliable because they reused the stock bmw/borgwarner CHRA - and borgwarner is a billion dollar company with a crap ton of money and engineers behind rnd leading to some of the best turbos in the world and turbos used by OEMS. That's why pure's old turbos were so reliable, because they reused already tried and trued CHRA's made by BW. The new pure 500 is brand new made from the ground up for pure by who knows - but it is likely made in China by the few turbo companies over there just like the n55+ is. This means the new pure 500 has zero reused parts (asides from the exhaust manifold) and therefore reliability will be an unknown just like the n55+. The thing pure has going for them is their excellent reputation for taking care of their customer, so if it does fail then you know it will be warrantied. Other than that you can't simply say it will be more reliable.

So the pure turbo name has a good reputation, but this turbo certainly isn't tried and true - atleast not yet because it is relatively new.

[ericlr1225]

Correct, pure500 is just another ps1 with core change. I doubt it would reach close to 500whp.
N55+ is with modified exhaust manifold. I'm pushing above 550whp now. We will see soon when I'm done tuning and put it on the dyno.

There's no core exchange fee with ps1 it's just like the vtt stage 1 now, you buy it and you get the entire turbo (minus the exhaust manifold) nothing to return.

Did you ever dyno the car with th3 n55+?

[Jiaim]

I don't know what to think about those costel upgrades.







They use a what seems a advanced compressor and turbine, in stage 1 configuration like pure 500.

Since everything comes from China now, this may be a correct product.

They have a G30-770 too.

[johnung]

I recently installed a Pure500 and I am going through the tuning process now. I considered the Shuenk 55+ and other turbos before choosing the Pure500.

As with everything these days there is misinformation out there. I was very familiar with ZM2’s German TTE460 turbo. He has documented his experience so well. The TTE460 (and the Pure500) has the attributes that I am looking for.

1) Stock responsiveness with a skyrocketing torque curve that goes straight up to maximum by about 2500 RPMs.

2) Much more power with a long lasting horsepower curve that goes towards redline, rather than peaking and quickly dying down.

ZM2 hit 500whp on the dyno with his TTE460 on an E50 custom tune. He dialed it down about 20whp to gain that longer sustained hp curve to redline for tracking.

I was getting closer to pulling the trigger on a German TTE460 when the Pure500 was announced. They are close in specs so I consider the Pure500 to be the improved version of the TTE460.

The Pure500 has the same two major attributes of real stock responsiveness along with a higher sustained horsepower curve.

Plus the Pure500 has no core charge. The TTE460 clips the stock turbine wheel, hence the core charge. The Pure500 uses a brand new GT28 style turbine wheel. It has the same number of blades (9) but they have a higher performance shape. Propeller design is a whole field of engineering. Think of the stock turbine wheel as being like the propeller on a fishing boat, and the Pure500 turbine wheel being like the propeller on a nuclear submarine. It’s a whole different level of performance and efficiency.

The new billet compressor wheel on the Pure500 is larger and more heavy duty than the stock piece. Based on these improvements expectations are that the performance of the Pure500 will be the same or better than the TTE460. My tuner just emailed that he thinks the Pure500 is already at 500whp with his most recent revision. I’ll dyno when he’s finished. It’s a FlexFuel tune so I’m not sure how many iterations will be necessary to test at various fuel mixes.

BUTT DYNO IMPRESSIONS
Driving it during this tuning process my butt dyno tells me that it’s exactly like the TTE460 with instant torque- no delay/lag, and much higher, longer lasting horsepower than my stock N55 EWG turbo on the same fuel and OTS Bootmod3 Stage2+ MultiMap FlexFuel tune.

COST OF INSTALLATION
The Pure500 is potentially much less labor to install. The entire stock turbo assembly does not have to be removed. The stock turbo can be detached from its exhaust manifold and the Pure500 can simply be dropped in its place. I spoke to one guy who paid $1000 labor to have his installed. Now of course it’s easier to do this with a RWD than an XDrive. And that’s barring other parts that are found to need replacement which can increase labor costs.

COST ADVANTAGES
The Pure500 is only $1,095 with no core charge. The TTE460 especially with shipping back and forth from Germany would have been 3x more costly. The Pure500 was announced about 16-17 months ago. It’s been selling as fast as Pure can make them while maintaining strict quality control.

Of course we think of aftermarket turbos for higher performance on the street and tracking. But Pure said that the stock N55 turbos have been on the road for many years and many miles. They are seeing the other large group buying Pure500’s as drop in replacements for stock turbos at their end of life. Makes sense at only $1,095. And owners will feel a nice bump in performance even on the stock tune and pump gas. Of course the Pure500 also provides more performance without delay/lag for those limited locally to pump gas but who are willing to tune.

NAMING CONFUSION
Many people do not understand turbos referred to as Stage 1, 2, or now 3. I often read comments that the Pure500 is “only” a Stage1. Sometimes this originates from competitors looking to create negatives. It’s used as a put down.

Years ago Pure Turbos actually introduced a turbo called “Stage1” that they still sell. It is the same size as the stock N55 EWG. So it was an upgrade for the smaller N55 PWG, and a comparable direct replacement for the N55 EWG. So when people hear the Pure500 labeled as a “Stage1” turbo they automatically equate it to being the same size as the stock N55 EWG turbo. IT IS NOT! The Pure500 is larger, more efficient and capable of a lot more power than the stock turbo.

In the vernacular of Stage 1-2-3 turbos, Stage1 is more equated with using stock sized components and delivering stock responsiveness with no added delay/lag. I’ve seen more people referring to the TTE460 & Pure500 as “Stage 1.5” turbos, which indicates both quick responsiveness and much more power.

TURBO EVALUATIONS
I mentioned that I had considered the Shuenk 55+ turbo. I evaluated companies and products. The two companies couldn’t be more different.

Pure is a large well established company with a broad solid product line and an excellent reputation. I’ve known many guys who have used their products and say good things. I’ve called Pure tech support a number of times over the years and they’ve always been excellent at answering my questions. Every Pure person whom I’ve ever spoken to has been very professional.

Shuenk is a much smaller niche company with fewer products. They used to be called Frankenturbo. Their FaceBook page has referred to some product that went wrong and had to be scrapped, which sounded like they rebranded with this new Shuenk name but still kept the old name around. Kinda the opposite of Marketing 101 in trying to build a proper brand name. It causes confusion. They also have a third company name called Midnight Motorsports that they sometimes refer to as if it was unrelated. The cult followers on their FB page give them high marks for customer service but at the same time I’ve read guys say that things can turn chilly in a hurry on a call to their tech support.

They heap on all kinds of supposedly unbiased technical information but the more I looked at it the less that I trusted it. Even a guy I know who is a proponent, rolls his eyes at the technical info they provide, especially virtual dynos. I took this to mean that they may be heavily massaged in the company’s favor. I personally wouldn’t trust any company produced dyno. I’d want to see more than one dyno and from actual customers.

Also Frankenshuenk’s expertise grew out of experience with E-Series PWG engines. They recently bought an EWG car for testing. It was obvious in their posts how little they understood the EWG environment.

One really disturbing thing to me is that they are actively promoting a Midnight Motorsports Fogr device as an alternative to an HPFP upgrade such as a Dorch. This Fogr was designed for N55 PWG cars with old N54 style HPFPs that don’t have a viable upgrade path. It basically sources fuel from a T in the fuel line before the HPFP and squirts it into the engine using an injector in the throttle body. It is a very rudimentary solution but it works when there are no other better alternatives.

This Fogr has no DME control like an actual Dorch HPFP. And it requires a custom tune to adjust for this extra fuel that the engine isn’t expecting. Shuenk is actively promoting this on their Facebook- insinuating that it’s a cheaper alternative to a Dorch HPFP. They really downplay/do not reveal that they are selling a piece of hardware to N55 EWG users with no DME control and that requires custom tuning to attempt to control it.

Probably the weirdest thing to me was how often Shuenk brings up Pure. Always looking for ways to bash Pure. Constantly claiming that they are leading this or that and trying to paint Pure as following them. At one point they tried to claim that they invented the upgraded turbo inlet pipe a couple years ago when in fact Pure invented it for the N55 about 7-8 years ago. Shuenk seems to have an unhealthy fixation with Pure. Yet in none of my conversations over the years with Pure did they ever mention Shuenk. They focus on the attributes of their own products.

The deeper I got into evaluating the more obvious it was to me that Pure was a solid reputable choice. FrankenShuenk seems to me like a marketing company looking to sell anyone anything by trying to masquerade as a technical company.

I already mentioned that I FrankenShuenk has taught me to not trust the supposedly unbiased technical data they put out. I also don’t trust their marketing jargon, especially when it doesn’t even match their own data. They constantly repeat that their N55+ turbo has “stock spool”. They repeat it so much that they have others saying it as if it was fact. They try to paint themselves as having the same responsiveness as stock as well as higher power than anyone else. Literally all anyone has to do is compare the torque curves to see that they aren’t telling the truth. Bring up the torque curves and you get more repeating their “stock spool” line and a whole lot more technical mumbo jumbo to try to convince you that your own eyes are wrong. Please see attached torque curves comparing the TTE460 that really mimics the stock turbo’s responsiveness and lack of delay/lag to the Shuenk N55+ with a torque curve that does NOT match their claims.

Anyway that’s been my experience. Hope it helps someone!

Yup, if the Pure 500 had been around three years ago when I started pioneering ethanol and Stage 1.5 turbo setups on the N55 (along with help from PTF & Dorch), I would have gone with it over the TTE460 just like johnung did. At least I got a really good deal on it (including complete turbofold) barely used from a forum member.

From logs I’ve seen, looks like the Pure 500 will make similar or maybe even a little more power than the TTE460, depending on fuel type, and boost & timing amounts. The dynos will tell all soon!

Yeah, i tried giving doug harper a chance. Just bc he’s offering another product and competition is good, but he’s not 🤔 “pleasant” and quite twitchy…i also think the n55+ setup is a good offering size wise..between pure500 and 750..Can push really good power with just a upgraded hpfp. No idea on reliability though…

Agree on him promoting things that have been out for yrs as new developments towards his fanbase..After the fog’r they’re now developing wmi injection systems as another “development”….idk man..I try to offer helpful input and questions, but he goes on attack mode often.

There’s a Pure500 dyno using 93 octane on the Pure500/750 thread. 455whp!
I’m scheduled to dyno mine on a preliminary FlexFuel tune using ethanol next week. See link and graph.
