N54 Turbo query

[SlowE93]

Let me know when twins do 800wtq at 4k

This is a stock n54 with a smaller EFR turbo roughly equivalent to a PTE 6266. I say roughly as we know a 6266 maxes out at 800whp on an n54 + dynojet.

The dyno numbers and ETs the S58 is putting out just makes me want to sell my car. Can we please never mention that engine again?

@Torgus @RuskiRacer Top mount or bottom mount

You gotta answer torgis question before we can further assist you

Tits or Ass man?

Tits for sure. But needs to be a good mix, not to much of either.

Well said well said . If money were no issue at all id look at the ces kit. Otherwise top mount is my preferred route . Keeping the wastgates down low like some top mounts do it is a good way to keep heat down low as well and keep the gates cool. Heat management should not be much of a concern there's plenty of good thermal control products out there

That 3d printed head has to be putting in some work

The cylinder head is NOT 3d printed! Probably the biggest misconception in the S58 world until today.

They are using 3d printed cores to realize complex structures and seem to use sand casting as the manufacturing process instead of die casting.

These are the printed cores for the casting:

Sooo its 3d printed lol

What?

I'm sure bmw uses a process similar to this for doing there cylinder heads

No.

The core is simply a a shape that is used in sand casting. In sand casting they are so called "lost cores" and basically destryoed after the sand casting process. They need to be destroyed as they are basically the negative of the cylinder head. If you look at the picture you can see that the piece looks like the inside channels of the head.

Your video has nothing to do with the process of how the head is made.

I don't think you understand the process ... might want to do a bit of research on the process @JohnDaviz is referring .... oh ... and lol ....

 

[Torgus]

I think a 3d printed head would be insanely expensive.

The 3d printed Inconel Manifold is cool tech but cost wise it makes more sense to just fabricate it up.

A head printed to the requirements of an OEM... That thing may appear in a Koenigsegg but not in an affordable BMW anytime soon.

Long term material behavior is an issue. Consider Paul Rosche pulled M10 engines out of German junkyards to build F1 motors, as they were better suited for endurance than fresh motors. There is the product, then the product over time, then the product over time x over use.

Am I still in my thread? Lol

My turbos should be arriving in two more weeks. Can't wait to see them! Not to excited about figuring out how to put the subframe back in. Ugh, I look at it on the floor of my garage every day with pure disdain.

On another note. Nice discussion on turbos that spooled up.... pun intended.....

Also, who cant decide if they prefer top or bottom mount?
