Early testing of our new B58 Stage 2 turbo has yielded some awesome results!
586whp, 93oct pump gas only and spools at 3,200prm's!
They ran out of fuel on the next run but it should easily eclipse 600whp on pump gas only!

The Compressor wheel is a similar design to our TTRS and N55 turbos with 9 full length blades. I'll add some pictures to the thread soon .

How about compressor and turbine wheel inducer and exducer diameters? Helpful to an extent in comparison to other turbos.

Most amazing thing us this actually now makes the b58 a most likely more reliable upgrade path as the n63 with similar potential.

What's actually amazing is the ability of the chassis to put the power down. Small car and proves it doesn't have to be a land yacht to cut times.

B58 is what the N55 should have been.

I had a m340 loaner for past 2 weeks and that thing felt great for a stock car. My f10 rides way nicer but as a sports car the g20 is sob composed it blows the 440 out of water I cant wait to drive the new 2 door

How would you compare this setup to a tuned n63tu and a pure n63tu. It looks like this is making more power than a tuned n63tu I dont know how the response is but that's why I am asking cause my x5 lease is almost up and I have to decide between b58 or n63tu in next car cause after buying my 2016 550 I was really thinking of getting a used 2018 x5 cause we have one now and love it but ours is n55 I was gonna get a n63 but now these results make me think 2019 b58 may be way to go and just put a stage 2 turbo on it.

M57 x5 if I were buying BMW trucks. Not a big fan of BMW V8s outside the E39.
