Okay... how the hell did you get the nut on the flange of the turbo? Everything ive seen says to do it from the bottom. I cant get to it from the top or the bottom or anywhere. I can kind of see it from the bottom but thats it.

Im an xdrive auto car. And honestly i dont see how the hell its even possible.

There are no videos online anywhere that i can find. Im at a complete loss. I have the oan and rack cover off.

No, am I supposed to? I havent been able to find any videos or anything much less a good actual write up on what I need to do. Other than... get it from the bottom.

Are you following this guide? The water pump might only be necessary if you're doing the diverter valve at the same time.

Yes... I already have everything disconnected and everything, I just cannot find a way to get to the nut. I can only see it soft of from on angle and there isnt any way that I can see to get anything up to it.

I didnt see anything about the water pump in those directions... Not doing the diverter right now anyway.

Finally got her done. Basically the data suggests once i hit 41.4lb-min on the maf i see no more regardless whats happening so im unable to verify anything. Logs shortly

Curious what your initial impressions are with the Pure Turbos Inlet? Getting mine installed in a few days.

Pure is great in general... in regards to instructions and etc or help... complete garbage. I emailed in and the reply I received was polite and the guy was great but he couldn't help at all and referred me to this site and to maybe ask Bryan Kiefer @ Kies... It was hilariously frustrating.

Post install observations... Its louder. There is a noticeable more intake noise (already running the injen intake). Its about a half inch increase in diameter so it is a rather big change so its not surprising there was a noise change.

Driving the car I dont really notice anything. However, I haven't been able to drive the way now in about 10 days due to time frame where i started pulling things apart in preparation for the install till yesterday.

Here is the logs...

This was the last log before the inlet
http://www.bootmod3.net/log?id=5d87c19fc090c658131412ee

Log from yesterday post inlet
http://www.bootmod3.net/log?id=5d9e32c1ae729b770a4213b2

You can see that I hit 41.4 on the Maf reading and it never climbs which Im guessing is because Im maxing it out, so I have no basis for comparison to see if it reads higher on flow or not. Not really seeing any real signs of change on the waste gate duty cycle. Since Im an EWG car, they are always high and BM3 says I do not have a leak based ont he numbers.

Did it hurt performance? Nope... but did it help? No idea tbh. I would say that its obvious why it would help with an aftermarket turbo set up and maybe on stock running really high boost.


Mods are..
Injet intake
Charge Pipe
VRSF 5" IC
Catless DP
BM3 E30 Map
BMW Trans Flash

Sorry it was a hassle for you. Ironically, Kies is doing my installation. I calculated, from pipe diameter measurements that were posted, that the Pure Turbos Inlet is 42% larger at that stock constriction point. I'm curious why that would translate into a noticeable sound volume difference. Perhaps your aftermarket intake is amplifying the sound so that you notice it.

I've got the M Performance intake which maybe sounds a little louder than stock because it has an extra air intake hole in the bottom of the air filter box. (That hole faces forward.) I use a drop-in aFe Pro Dry filter. Now I'm curious to see if I notice any sound difference.

Please post before and after logs if you can. I'm very curious to see if you have the same increase in MAF readings and how much they differ from 5000 RPMs on up. I haven't recorded a log but I may give it a try so that I have some "before" data before my installation.

You may not notice much of a sound difference with the stock air box.. too much built in sound baffling.

Logs are above.. as you can see, my results were useless.

My upgrades were installed at Kies:
1) Pure Turbos Inlet
2) Turbosmart N55 Diverter Valve

My "before" logs weren't useable but I did get one good "after" log and will put the link below. I also attached a summary page of my MAF readings versus yours. Mine peaked at 4.1 higher than yours.

http://www.bootmod3.net/log?id=5da5d76bc090c64dcce41c79

Our cars are the same: 2015 335 N55 EWG
So I'm trying to understand how our mods may differ to see what may be different.

You had previously listed your mods as:
Injet intake
Charge Pipe
VRSF 5" IC
Catless DP
BM3 E30 Map
BMW Trans Flash
Pure Turbos N55 Inlet Pipe

My mods during my log were:
M Performance Intake/ stock air filter
Evolution Raceworks Charge Pipe
Wagner Competition EVO1 FMIC
Fabspeed Catted Downpipe
BootMod3 Stage2 N55 EWG 93 Octane
BootMod3 Auto Transmission Flash
Pure Turbos N55 Inlet Pipe
Turbosmart N55 Diverter Valve/Blow Off Valve, Plumb Back model

I'm scratching my head trying to figure out what might cause the differential.

1) Our intakes are very different. Bryan and I were discussing that some intakes can sacrifice actual power to make noise but we didn't discuss the mechanism for why that happens.

2) Our BM3 tunes are different due to fueling but I would assume that an E30 tune would be the same or better than a 93 Octane tune.

3) My DV is an upgrade from stock but my assumption is that wouldn't come into play at all with the accelerator floored in 3rd gear. That's a small snap shot of data when the valve on either car should not open.

Somewhere in this thread it was mentioned that there is some correlation between MAF value and horsepower/torque. Do you know what that value is? Where is comes from? How accurate it is?

Any thoughts on all this?

You can't compare cars running different tunes, in different climates and altitudes. You needed to have a before and after log on your car to make any meaningful comparison. Right off the top Phantom and your ambient pressures aren't the same, which has an impact on airflow.

Yeah.. I should have higher maf numbers than you in general because of the tune, all things being equal that is.

The difference is the intakes... I guess we cant use any of the data for comparison sake because we have different intakes. There is something interesting that I noticed after looking at my older logs though, more on that in my reply below.

Yeah. there is a relationship between maf numbers and power. the higher the number the higher the HP. Ive seen numbers ranging between 7-10hp per... so using 10hp... 40 on the maf reading would be 400hp etc.. 41 would be 410hp etc... but there isnt an exact number but it does give you a good easy way to see power increases or a decrease.

I went back and looked at my old logs... stage 2 93 octane, with less mods, less boost, hot or cold etc etc.. same maxing out of the maf at 41.4. So something in keeping it from reading higher. Right now I dont know what it is.

41.4 is the highest the maf sensor can read.
Looks like you live in a location with very dense air (ie. not high elevation).
People comparing maf readings or doing mods based on maf readings seems pretty misleading, it really has to do more about air density than air flow. More dense air has more oxygen.

41.4 is not the max limit to the readings. see johnungs recent log a few posts up lol

We have the same car, 2015 ewg n55. and hes seeing higher readings

Where can you buy inlet 2 from? I asked mike from extreme and he said they don't.

Thanks! Do I need an adaptor for this to fit stock turbo?
