Big and light turbine and more custom mods that make the difference.
Hope to have a nice surprise by the end of the week.
It should spin easy on ceramic bb cartridge.

Hi Mac,

Look forward to seeing more progress updates, very interesting build plans!

May I ask more about the larger injectors? This looks to be an m57n2 engine from the pics, so it will be with the 286 piezo units (similar size to the 231 330d injectors).

What options are there for larger injectors?

I'm aware of some from an Audi sq5 or similar, but they have wrong spray angle. The 313 n57 injectors flow 15-20% more (I think) but are different bore and size and don't work with m57n2 from my understanding. Cheers

Regards,
Niv

286hp piezzo injectors are quite big for my power goal of 500+ , dont see a reason to upgrade them.
The N series injectors might be bigger but injectors are too short, can not be used.

I found a working solution but there is a lot to modify in order to make them work, so why bother. Plus all the maps that need to be put in the software.. not at this time.

Meanwhile the other car has been on dyno after some minor repair
548hp 950nm , no smoke

What sort of max power do you think you could get out of the 286 injectors with r90 pump, and what sort of rail pressure?

The manifold enter is 48mm of diameter, did you made any enhancements there?

Improvements everywhere we considered necessary. Nothing is left untouched.
Now since that i have some extra time, perfecting some aspects further.
A lot of dremel and carbide work and some healthy time on my lathe.

Stock 6hp28 with custom software on all the cars except the fastest one which runs 8hp+standalone.

Got 3 turbos ready but cant test them due to lock down.

70mm intake all smoth inside


test before machining the housing for compressor
