N55 Pure Turbos Stage1 and Stage2 upgrade!

Post by Peter@Pure » Thu Jan 19, 2017 8:44 am

With this thread I would like to promote the N55 Pure Turbo upgrades. There are a few differences between the different N55 models.
- E series PWG N55: Pneumatic Wastegate
- F series PWG N55: 2012 to june 2013. Same PWG turbo as the E series N55 but different intake/inlet system
- F series EWG N55: Starting July 2013 and onwards (similar for M2). Electronic Wastegate control, same intake as F series PWG, 4'' turbo outlet to downpipe.

From a performance point of view the biggest difference between PWG and EWG N55 is the larger compressor wheel the EWG turbo has from factory. It is slightly smaller still than the Pure Stage1 turbo offering. Furthermore the EWG models have a 4'' outlet to downpipe. This reduces the backpressure a bit providing slighly improved performance as well. The larger compressor wheel on EWG models allow those to maintain power better in the upper rpm band while on PWG models the power/torque drops down a lot faster when tuning the stock turbo.

For this reason EWG models should go straight to a Pure Stage2. While the PWG models still have great benefit from a Pure Stage1 (if on a budget).

The stage1 upgrade has the cold side bored out so a larger compressor wheel can be fit. As well as upgraded internal parts.

The stage2 upgrade has both cold and hot side upgraded. As well as other internal parts. The power band above 4000 rpm is just insane and amazing. An inlet upgrade is recommended when upgrading to stage2 turbo. This will allow the turbo to breath more easily and it will give a noticeable performance bump when pushing for 450+ hp numbers. Due to the weak spring in the stock diverter valve a GFB DV+ upgrade is recommended with the turbo upgrade.

So far the technical details. What power can you get from the upgrade? All dyno's ofc read different but in general the following numbers are possible:
- PWG stock turbo on 98 ron fuel: 360-380hp depending on other mods on the car. Due to the small compressor wheel the power and torque go downhill fast the further you tune it.
- PWG stock turbo on 98 ron fuel with meth kit: 380-400hp possible. Peak will be around 5k in the rpm band and dropping off very fast from there. Again the small compressor wheel being responsible

- EWG stock turbo on 98 ron fuel: 400-420hp possible. The powerband is wider than PWG turbo but optimal shift is around lower 6k rpm range.
- EWG stock turbo higher octane or with meth kit: 420-440hp possible. Again when pushing EWG models you will see that peak comes quite early in the rev band (around 5500 rpm) and go downhill from there

- Pure Stage1 upgrade on 98 ron: 420hp possible. The powerband is a bit wider than EWG stock turbo.
- Pure Stage1 upgrade higher octane or with meth kit: 440-450hp possible. Power and torque will start dropping in the upper 5k rpm range.
---> So compared to stock turbo you get a more broad powerband and a higher peak!
Dyno stage1 turbo at different boost levels:
Image

- Pure Stage2 upgrade on 98 ron: 450hp possible. Very broad powerband. Peak past 6000 rpm. You will run near the HPFP limit.
- Pure Stage2 upgrade on high octane fuels with supplemental fuelling (meth/pi): 550hp possible. A very very broad powerband with a brutal topend! Peak around 6k rpm.
Dyno at different settings with port injection upgrade and low pressure pump upgrade:

Sidenote: Tuning was done by myself using JB4 only. Measurements done at BR-Performance in Willebroek, Belgium.

Here another result from a local M2 customer running 98/E20 mix with Fuel-IT LPFP and port injection upgrade and Pure Stage 2 turbo JB4 tune.
The result is in whp (not crank hp).

Is there anyone you can recommend to install Pure Turbos in Australia?

Any specialised BMW shop (or dealership) could do it. It's just like OEM turbo replacement.

Ok thanks, I have someone in mind for that. I currently have racechip ultimate but no other mods (which I should add isnt particularly happy in the australian summer). What is a basic build list to work towards getting ready for stage 2 turbo?

If you want to start with a pure stage2 i do recommend you have the following mods but it depends a bit on the power level you are after.
For 450 bhp:
- Chargepipe
- Sportcat or decat
- JB4 (or other tuning device that can handle stage 2 turbo)
- Intercooler (depending on your driving style, eg if you do occasional pull you could get away with stock intercooler in colder climates)
- Inlet (to let turbo breath more easily but once going for 500 it is required)

For 500 bhp+:
- Chargepipe
- Decat
- JB4 (or other tuning device that can handle stage 2 turbo)
- Intercooler (must for the hot air it produces)
- Extra fuelling and higher octane (Meth, port injection, lpfp upgrade, E85 mix)
- GFB DV+ upgrade
- Inlet upgrade

That's about it.

Very helpful Peter, thanks very much, I'll start shopping in next few months.

Regarding the meth install, I see your meth bottle in the rear boot space in one of your videos, can it be installed somewhere other than the interior? (I have a 13 month old daughter who rides in it when mum goes to work in our 4wd, she loves the power of the N55 but dont like the thought of the bottle splitting in an accident - and yes I drive sensible with her)

Shame I had to replace my charge pipe recently with OEM (no Australian suppliers have aftermarket N55 in stock and it's my daily driver so needed it back on road ASAP).

On F3x/F8x models BMS has a hidden stealth tank that goes under the lid of the trunk. However it does not fit 1 or 2 series cars.
Since you are located in AU, you could opt for LPFP upgrade and Port Injection from Fuel-IT. You guys have E85 at the pump there so no need for meth and you run all from the in-tank fuel. No risks for the little one!

I am also Fuel-IT reseller just so you are aware. I also always have F series N55 alu chargepipes in stock (RWD and X-drive models).

Tnx,
Peter

Ah ok great to know, by chance I have the only E85 fuel seller in 60km radius less than 1 km from home.

I'll make contact in next few months for some pricing.

This chap (also in australia) has a contact who can do custom meth tanks, which sit beside the battery tray - its for a 1M battery tray, but it may be possible to ask for different mounting option.

That's very tidy, thanks for pointing it out.

If access to E85 I would just run E30-E60 mix whatever is convenient. You could do full E85 as well but the stage2 LPFP will be at its limits. But I heard stage3 LPFP will come as well. Octane wise for st2 turbo E50 is more than enough though. Custom meth tank is possible but I think due to size it will be empty rather fast and requires frequent fillups.
