Would this turbo work with lower boost pressures, say in the 12-14 psi range?

I'm not so interested in peak power gains, but the ability to have a nice midrange that stays flat till the AT 6700 rpm up shift.

Traditional stage 1 or stage 2 power numbers suffice for me, 300-350 rwhp max. I would probably run stock down pipes or maybe aftermarket catted, fmic, charge pipe if necessary, no meth, crazy boost numbers, corn fuel blends etc etc. Shell v power 93 all the time.

In other words, I understand I wouldn't see the full gains possible with my modification philosophy, but would there be any detriment using this upgrade with my proposed setup? Will I lose much noticeable power under the curve just to hold it up top? I spend way more time 2k rpm to 4k rpm than I do at 6k, public roads on my day to day roads aren't conducive to 3rd and 4th gear redline runs, but I hate how this engine runs out f steam.

This setup seems like a no brainer if so when these n55 turbos start going out in a few years.

Hi Jec1,

Yes, in fact we expect to see a bigger top end gain on pump gas tunes. We originally requested that our customer with the test car did pump gas baselines. He misunderstood us and only did e85 tests. These e85 tests show the turbo close to its max rpm. If these were pump gas tunes, and lower boost pressure, the turbo would be more in "the meat" of it's efficiency range (not maxed out). So we would expect to see larger differences and gains between stock turbo and PURE turbo. I hope that makes sense. Our N55 335i shop car will be thoroughly tested and documented on pump gas. Thanks

It does make sense, and that's very good news for people like me, the set who would otherwise be looking at Dinan type products and set 'stages'. Many people outside of these boards are interested in a little more 'oomph' without worrying abt logging, meth flow and all the other nonsense that comes with dyno bragging rights. I have a growing business and a household to support, and I'd rather invest in hiring another employee or knocking off another improvement on the long list for my home than pushing my engine to the ragged limit to get 20 more horsepower.

May I suggest that there is a large contingent of people who buy these cars and are interested in spending another 5-10k for comprehensive stage upgrades. its why the Dinan 'stages' for the 550i seem to sell relatively well. Granted the profile of a 5'er owner is typically different but in any event nobody aside from Dinan and to an extent Cobb seems to offer comprehensive set upgrade 'stages' for the 335i. I got a 335i for a reason; my choice. M3 is too raw for day to day, 5'er is too boatlike. I have better use for funds than a Porsche at this point in my life, and there isn't really anything else that interests me. I've also done the tuning thing before, trying to put together a race car for the street than winds up being neither a real race car nor a practical street car, I'm too old and I don't have the time or patience.

Offer a set package, combine this turbo with whatever other products are necessary to support a given power level and offer a conservative off the shelf plug and play tune that leaves some power on the table but offers reliability and longevity. Sell these packages for a set price in conjunction with an authorized retailer/installer network, so someone can get everything they need for a bit more power and not have to do the legwork on their own. This model has been used countless times, but it really does seem to be lacking for these cars in terms of a professionally put together packages with all parts included for a set price. Set it and forget it is what many owners want, BMW is about refinement, not filing your windshield washer tank with explosive liquid.

In another couple years, n55 turbos will tend to be entering the mileage where failure is expected out of warranty. Your pricing is on point where it makes sense to upgrade at that juncture, however a complete upgrade solution would really help sales I think.

PS- what is approximate target boost psi on the 'pump gas' tune you mention?

Well put Sir.

We agree with you completely. That is precisely our goal. With so many overpriced upgrade turbos on the market, we wanted to produce an offering which is affordable and practical. Thanks

We will have the PURE Stage 1 installed on our shop car soon. We can then provide a 2nd set of dyno results. We have shipped 3 out the door this last week. Any questions I can answer for you? Thanks!

[marCOCOpuffs]

I'm debating on getting this done. Make sure you get your shop car tuned with the AP!

Where do we stand at this stage with this upgrade. At present, I have a 2011 335i with the Dinan Stage II Tune.

I am interested to know what this upgrade would me for my spirited daily driver in terms of performance and what I would need to make this transition.

Thanks,

Thanks,

This upgrade will add around 45whp on the top end rpm range. Gains are seen from 4700 to 7000rpm. This turbo fills the void where the stock turbo runs out of breath. PM sent, thanks

Any updates on stage 2 progress?

In progress...

It will be a while before the N55 PURE Stage 2 is available. RB should have his N55 Stg.2 available sooner. RB is doing a different setup than we are. For those wanting a Stg.2, I recommend waiting for the PURE Stg.2 or the RB Stg.2. Both will be excellent.

We can currently build a N20 Stg.1, and the N20 Stg.2 is estimated 4-6 months away.

Thanks guys

[JETmn]

Good to know where you guys are at, thank you!

[335iFFM]

Any update?

[JETmn]

Sounds like it will be a couple of months. It is still pretty early in development.

Hey guys,

We have been bolting mods on our shop car. We will be using it to provide a second set of results for our PURE Stage 1. BTW, we have a few more tricks up our sleeve for the Stg1. We had a larger upgraded powdered steel thrust bearing system produced for these turbos. It will be utilized in our Stg1 + Stg2. Including the upgraded thrust, the Stg.1 turbo that will be tested on our shop car will have 3 changes made compared to the turbo that was used previously for the posted dyno results. We are expecting even more gains with these other changes. We have sold and shipped 6 of the PURE Stage 1 turbo in the last couple weeks.

The PURE Stage 2 is in early development. Stage 1 is available and shipping.

I agree! Lets work out a deal!

[WickedWhiteN55]

New, bearing type, stage 1 for N55. Price shipped to 78660?

[PeterPure]

Awaiting for mine to arrive

[papiti]

KEEP UP THE GOOD WORK. HOW MUCH SHIPPED TO 00969? N55 OF COURSE!!

[D's Bimmer]

Am I right in thinking this upgraded Stage I turbo + FMIC + COBB Pro tuning from PTF would make this N55 sing?
