Those with a 540i may find this interesting
Not BMW directly, but these guys did a full tear down of a B58 from the new Supra. It's a great bit of insight as to how this engine is constructed.

For those that found the above of interest, .. Papadakis just managed to punch 1033 Horsepower out of their B58 build. Heavy mods, but engine still on a stock crank. Very very impressive!
Just shows how strong the bottom end of this motor is. |

Huh? It’s the exact same engine as what has been in the 540 since 2017. Rated exactly the same...or should I say “under rated exactly the same!

Been watching these videos for some time with interest.
Watch the one where he dynos it and sparks start flying out of the top of the Valve cover Luckily it was not too bad in the end, but it looked scary.

Thanks for your insight. I admit I assumed that because the Supra is rated exactly the same as the 540 that it is the same engine.

Yea they used custom port fuel injection because of the higher fuel rates. The B58 has direct cylinder injectors from the factory. They just had them sitting in place though and one of them melted, so the sparks you see are bits of the combustion and the direct injector flying out the top. That's why they ended up plugging the direct injection system.

Yes, the official HP via the BMW website is 335 HP, but as we all know that BMW underrates their engines in terms of HP, I was wondering what other HP specs have been listed for this engine?
