Bimmer Performance Center Built M57 Thread

Phil@BPC · 09-13-2018, 02:20 PM

This thread will be showing our built M57 and the modifications we have done to the chassis. We are very excited and can't wait to share the progress with everyone here. Specs will be shared later but to get the ball rolling, here is the candidate and making progress on getting the drive train out of the car and upgrading the rear subframe assembly. I'll be updating this thread as we continue to move forward

E90 M3 rear subframe getting transplanted into chassis.

Torqu3 · 09-13-2018, 02:45 PM

So what's the goal with this? Track car? Drag car? Just a really terrifying DD?

da_trem · 09-13-2018, 06:36 PM

Now thats what i'm talking about!

mcmahand · 09-13-2018, 06:54 PM

This should be a very interesting build! I take it the rear diff was regeared or 80mph with be around 3600rpm

Real question is hybrids or custom.

apexit4 · 09-13-2018, 07:27 PM

This looks like a very interesting thread! I'm looking forward to seeing future updates

Quick question. It looks like you didnt disassemble the front end to remove the engine. Did you pull the engine out along with the transmission like that? Or, as I suspect is more likely, did you get everything loosened to the point where you could drop the engine and transmission a bit so that you could access the bolts at the top of the transmission? Also, did you end up removing the subframe to do so?

Lambkilla · 09-13-2018, 07:34 PM

Bump, interested to see where this goes.

Phil@BPC · 09-17-2018, 09:33 AM

Sorry for the delay we just had a hurricane come through. We are ok we just had a lot of rain and wind come through.

The current goal of this build is to be the most badass 335d in North America. We plan to take it to Half Mile events, drag strips and road courses.

The current diff is a 3.15 ratio (the manual gearing not the DCT gearing).

We have hybrids we will be installing for this build. We are going to use something a little extra to help boost power output. More on that later

We pulled the engine out by itself, we left the transmission bolted in the chassis while we were pulling the engine. Then we removed the transmission afterwards. We didn't remove the subframe or take apart the front end during this process.

That looks expensive.

Was thinking the same thing...

could have been a hydrolocked block from a leaky EGR cooler making it "close" to a rebuild cost plus extras.

Very interested to see the back pressure #'s seen with more boost. I know 60-70psi @2500rpm is

already. Has bob dialed that lower now?

Well....I meant the cost to have this work done by the end consumer. RIP wallet lol.

Not sure about the back pressure question.

What?

Currently the maximum back pressure reading I am seeing on my BPC hybrid build is 72.5PSI, happening at around 2500rpm at WOT...

I was wondering with this new hybrid setup have they got that lower now.

335dsleeper · 09-18-2018, 07:13 AM

How are you measuring 72.5psi?

Reading from Obd2 port.

Phil@BPC · 09-18-2018, 08:47 AM

This 335d was purchased with known rod bearing failure.

This is an open checkbook build allowing us to explore and test the M57 platform to see just how far it can be pushed with today's technology and one off specialty made parts.

Phil@BPC · 09-18-2018, 08:59 AM

335dsleeper · 09-18-2018, 09:50 AM

Hmmm. Can you post a log?

Stock sensor maxes at 58. Not sure how you’re seeing 72.

I'm in the process of disassembling my old M57 engine and trying to find a nice interesting use for some of the parts like the pistons. I sold some of the parts already but have doubts anyone will want to buy the head, pistons, camshafts, etc.

Skunkwerks · 09-18-2018, 12:44 PM

'Open Checkbook' is equal to what real world number?

Billysgoat · 09-18-2018, 08:48 PM

Very interesting to see what happens here.

Phil@BPC · 09-19-2018, 12:41 PM

We cut up a factory piston to show how thick it is in areas as well to show how its constructed.
