340 B58 PURE STAGE 1 Testing
 
3 Attachment(s)
Hey guys,

Just got our 2016 340i B58 back from PURE with the Stage1 turbo for a little fun. JB4 tuning for it is still a work in progress but turbo response is almost as good as stock and so far no problems making around 30whp more than the stock turbo up top. I've got some work to do on the tuning still but I'm pretty encouraged by the early testing.

The test vehicle is running the JB4, BMS B58 intake, BMS WMI, and PURE S1 turbo. Exhaust and emissions equipment all 100% unmodified. Boost juice and ~95 octane.

Attached is a dyno/log of of what we've worked up so far (@ 23psi) and also a log with the JB4 on map4 (stock tuning) for comparison. The stock tuning seems to run the turbo just fine at stock like boost levels which makes our life easier. I did a few runs up to 25psi (the current boost cap setting in the B58 JB4) and while it wanted to make more power there are a few tuning glitches I'll have to tweak first. Hope to see 500whp with this thing shortly. Then it's open season on lightly modified M3s.... :)

We'll be testing this car as part of our development fleet at Shift Sector 1/2 mile tomorrow. :burnrubber:

What about the price?

this motor seems promising!
respect to Burger and Pure for making this happen!

Peter @ Pure 10-22-2016 12:19 AM

Looks very good! B58 sure has potential!

Vorsprung_CJB 10-22-2016 09:04 AM

Making M240 even more tempting for me now.

Is meth required for BT at this point due to the fueling restrictions?

Also, is it normal for timing to zero in the low range like that? Saw that in logs of stock turbo B58 as well.

This is awsome!!!!!!

This is TERRYfic :-)

Great work Terry!:clap:

Is it possible that the E series can make the same numbers on stage 1 pure ?

Terry @ BMS 10-24-2016 09:33 AM

The car ran great at shift sector. Almost took out our 2016 Z06 Corvette... :)

Collected some good data and working on mapping improvements as I type this.

Nope, E series has the smaller exhaust side. 426whp is the most I have seen, IIRC.

I can't wait!!

That was at least E30, I know the turbo was maxed and dyno may have read a tad high. I have seen several others in the 400's though. Anyway, not to get this thread off track.

zinner 11-07-2016 07:10 PM

quite impressive results.

Terry @ BMS 11-07-2016 07:41 PM

Still poking along on the tuning on this. If I can work out a couple little things I think we'll see 500whp. :burnrubber:

Nanometer 11-09-2016 11:06 AM

Incredible results. Looking forward to more. I am sure all of the tuning and lessons from other platforms has helped get this platform up to speed. If the bottom end can handle it, you should be able to do 600 WHP with minimal supporting mods. Just unbelievable!

klipseracer 11-09-2016 04:14 PM

Nice Terry! That Z06 sure does move out

JB4OFF 12-02-2016 12:44 PM

Timing looks pretty low on those logs... how's the tuning going for this?

Terry @ BMS 12-02-2016 12:48 PM

Been working on things in the background and I think 500whp is within grasp. But still some software work to do.

Bours 12-02-2016 01:56 PM

So the b58 is making pure stage 2 numbers on the n55 with meth !? And no down pipe ? Thats amazing right ?

Terry @ BMS 12-02-2016 03:25 PM

The B58 engine is way better than the N55. Almost as good as the N54. :)

365 whp to 481 whp by just adding meth ??? Stock boost for b58 is ? And 23 psi will wear out that stock snail really fast right ? And running this much with no ***** ** damn

I know that this turbo is only a month into R&D but any word on when this will be available and what the price of the turbo will be.
