135i N55 DCT; PS2
Finally! I got on the dynojet at EAS in Anaheim, CA on 4/28/2022 to get some numbers on the PS3. It took a while, but I am happy I can finally share results with everyone.

Before I get into the details I wanted to mention a couple of things up front:

A big thanks to Pure Turbos for releasing another awesome product for the E series N55. I don’t think the product is posted on their website but if I get any information I will add it here.

Also a massive shoutout to my N55 tuning brothers, @JPuehl and @Stokes. Two of the most determined and persistent people I have met; a requirement if you are trying to self tune an E series N55. I think we have literally tested more than 500+ tunes between the three of us to figure out N55 tuning, and we are still testing till this day. Thanks fellas.

Overall Impressions, thoughts, etc.:

My car pulls like a freight train. I decided to upgrade from my PS2 because I was looking for a solution that made a little more power without breaking a sweat and was a little easier on the motor/drivetrain. For me, generating a massive amount of torque extremely early is pointless and puts a massive amount of unnecessary strain on the motor. At the same time, I wanted a faster car.

The PS3 was the perfect fit. Yes it spools slower than the PS2 when I am grabbing a log from 2,500, but that is expected. Even so, the tires still immediately light up from a standstill like the PS2. At a race RPM, the spool is awesome and I really enjoy the power delivery.

I will post logs below going wot at 4k, and you will see going from zero throttle to 18psi takes 700ish rpm, and to 24psi takes 1,000ish rpm. Loading up the motor a little bit or brake boosting shortens the time to get to boost even more.

My current 100-200 dragy time of 6.05 seconds, 60-130mph of 7.1 seconds, supports my car is decently quick. That was with less boost than the dyno run and some wheelspin so I know it will go into the 5s range. I will continue to update this thread if I get better verified times.

Here are the relevant details about my car/mods:
Car: 2011 135i, DCT
Turbo Setup: PS3 which has a GTX3582R ball bearing cartridge which should be good for 700whp (yes it’s big 😊). Turbosmart WG with 14lb spring. Turbosmart diverter.
Intercooler: VRSF race 1000hp intercooler
Intake: Injen
Exhaust: magnaflow 3.5" muffler, 2.5" to 3.5" y pipe resonator delete
Ignition: Delphi coilpacks, 97506 plugs gapped to .025
Fueling: PI spacer with 950cc injectors, AIC, Walboro 535 pump, E57 on dyno day
Boost control: GFB G Force III with the following settings; Duty Cycle 79, Gain 70, Sensitivity 35. Standard three port MAC solenoid.
Tuning: The tune I ran on the dyno is at 25psi, 9.5 degrees timing, 12.0 AFR. The tune was developed by @JPuehl, @Stokes, and myself via MHD.
Drivetrain: Stock DCT clutch pack with 60,000 miles, M2/3/4 flywheel, xHP stage 3 flash.

Dyno Results @25PSI (574.8WHP, 546.75 ft/lb STD; 561.01WHP, 533.60 ft/lb SAE):
Mission accomplished! Haha. I was really happy when I saw the results. The icing on the cake is the turbo literally isn’t even breaking a sweat. There is a ton more boost and power left in the turbo, but that is not for me at the moment so I stopped at the power you see here.

When I was building the overlay graphs to compare to my PS2, I noticed my PS2 dyno graph I shared a few years ago was using STD correction. I had no idea what that was so after some googling, I learned SAE is the more standard setting. I wanted to compare to my original graph so you are going to get a set comparing PS2 to PS3 using STD as well as SAE. I will also provide the PS3 graphs in both standards with RPM on the x axis (I can’t do RPM on the PS2 graphs because there was an issue with the RPM signal).

60-120MPH (ran out of room but this shows I will be in the 6s for 60-130. When comparing to my run above, I am .3 seconds quicker to 120MPH. Pretty clear it would of been a 100-200kmh in 5s. Hopefully can get a full run in the near future but she is definitely hauling butt!)

That is about all I have for now. Please let me know if I missed something or if you have any questions. I will of course update as I get more data, information, etc and thanks for reading!

This is where I go to dyno as well.
Nice dyno sheet. Pretty quick car !

I think your prayers will be answered. I am 99% sure the ewg version will come out at or close to the same time. Everything is the same, just different wg setup. 👍🏽

Also, really like the sound of that Magnaflow.

I was on the fence about doing one on my F32 - I'm not anymore. Lol.

It looks like an awesome bit of kit @houtan! Quick times also! Have you got any photos of the turbo/manifold? Or maybe the engine bay looking down? Is it single scroll? Do you think RHD fitment could be possible?

Thanks!

I don’t have any pictures or answers to your questions unfortunately. I believe pure posted some on instagram, but that was a while ago. Once I find out any additional information I will definitely post it here though.

Awesome results, and thanks for sharing @houtan ! I've been extremely excited for this turbo since Pure announced it back in January of last year, and I'm glad to see such great results. I know you stated it, but it looks like there is a good amount of room to get even more power out of that setup. Any idea on how much boost that turbo can push for those wanting to max it out?

Your dyno log looks great too btw. I found it interesting you tapering the timing from 14 degrees to around 8 degrees after boost is fully kicked in. Do you have any idea on how much timing you think you'd be able to run on that setup?
