Bimmer Performance Center Built M57 Thread

It would of been cool to see a custom intake manifold..

jeepinvader · 11-09-2018, 12:09 AM

Any need for upgraded injectors, or are the factory ones able to spit out enough go juice for this beast? I'm honestly surprised that these factory injectors are able to make as much power as they have been proven to do. This might be the build that finds their limit. Good stuff, can't wait to see more.

Yes, the injectors have to be heavily modified. During our break in testing on the dyno we used a stock r70 fuel pump (no meth) and the modified injectors we were able to max it out at 727rwtq and 450rwhp before it pressure dropped at 3500rpm. Still getting the last bit of the fuel system put together at the moment and we'll have some bigger numbers to show

Love seeing the D pushed. That is what she said.

727rwtq. Out of this world.

what do you guys measure torque in in the USA, ft/lbs or NM?

Soooo. what ever happened to this wonder car? is it safe to assume that BPC couldn't get it up and running correctly? Blew the engine right away? didn't get expected numbers???

Phil@BPC · 01-14-2019, 11:48 AM

The car is running and driving.

We are working with an experimental fuel system on this project and with experimental systems there are a few bugs to work through.

looool. perfect way to bait BPC into responding.

Perfect! Glad to hear back from you guys.. many people are wanting to see the final results.

R70??? Such a labour and you even didn't upgrade HPFP to R90? Most common mod to improve fuel on M47 and M57 with piezo. Why?

As stated above, we were breaking the engine in and at that point we did not have our new fuel pump.

I'm lost... when you don't change the diameter size compared to OEM, is the fluidampr supposed to increase HP or just to reduce torsional vibration on crankshaft? Specially on those cars that you raise rev limiter and the stock balancer isn't made to work such a high rpm range???

The fluidampr balancer was solely developed to give M57 users a solution to the horribly designed OEM balancer which was doomed to fail once you reached 60k or so.. I don't think anybody was expecting to gain any power from it.

Thanks for the clarification. That was my understanding as to why it was developed as well.

Is that a common failure worldwide or just in US? I'm from Europe and never saw such thing with multiple +10 years old 35d and +4x 60k. Still running strong on factory balancer.

Just saw this thread! I'm stoked to see numbers!!!

Very impressive numbers to the ground!! Can't wait for more updates...
Some videos would be nice.....
