Its from 4k ish rpm to 6500 rpm if you ask me. I have the csv so that tells me what i posted above. Can you post your csv as well?

The green line is rpm, not the blue. Blue = boost.

4k to 6500 makes sense it looked short so i was unsure. Sure I'll post csv on my thread can you post yours on here or wherever i dont mine if on mine or here

The csv file gave me cancer trying to read it lol but you did that pull in 5 gear targets started around 19psi you were hitting 20lbs because of the high gear you were in and holding 17 at 6500 rpm.. you cant compare that look to one done in 3rd gear that makes no sense

Why doesnt that make sense? I have the 8 speed auto. Gears 1/2/3 are way too short to show boost in the logs. Even 4th gear is short. Hence 5th gear pull. I think you have 6 speed transmission? So we cant compare same gear pulls as mine are much shorter in same gear

I have a 6spd Manual transmission. Who has the 6spd manual 135 then?

Lets just compare gear ratios:
Your car:
335i E9x manual
1st: 4.06
2nd: 2.4
3rd: 1.58
4th: 1.19
5th: 1.00
6th: 0.87

Mine:
1st: 4.70
2nd: 3.13
3rd: 2.10
4th: 1.67
5th: 1.29
6th: 1
7th: 0.84
8th: 0.67

This means your 5th and my 6th are the same. My 5th is shorter than your 4th and my 4th is shorter than your 3rd. Your 4th would be a good comparison against that 5th gear log of mine. You would have a slight longer gear so you would have a slight edge.

Im going to log 4th gear later today we'll see whats up then

Sounds like a good plan!

His log is more applicable to your stg1 log vs the 91oct log you were using in your original comparison...

That being said, Dark also has the newer n55 turbo and not that it changes power too much more but it appears that purestg1 is holding more boost than the vtt...would love to see if this is the case on the MFD<7/2013 turbos?

iuhutch · 07-28-2014, 11:31 AM

BUMP - still 1 unit left guys!...

He's in a longer gear than i am not saying its longer by much but definitely could be the equivalent of 1-2psi. Seems around 6500 rpm where he's holding 17psi im holding 16ish-15. We'll find out more once i get a 4th gear log to somewhat match his 5th gear.

Darkhold doesn't have the 4" turbine outlet, does he? If he does this is apples to oranges, but if he is still on the 3" then we should be in good shape. We will have tons of Pure turbo logs once the group buy finds the last person

OHH thanks for the clarification! So you do have the same turbo as us e-series owners? Is the only different that you have an 8-speed auto instead of DCT then?

Yes we will!

PeterPure · 07-28-2014, 01:15 PM

Yup only difference is the gearbox.

Ivan_Sal · 07-28-2014, 01:23 PM

I know someone locally who has this turbo, so if the offer is still available I'll take the 10th place.

I wouldn't base the turbo's ability to hold boost just on the turbo alone. Supporting mods will show the efficiency of the motor/turbo setup. An intake, ic, downpipe, charge pipe all should be factored in, even then every car/setup is different.
