Default 435i JB4 Dyno - 03-10-2014, 05:00 PM

Hey guys,

Was able to get our automatic 435i development car out for some dyno testing today. The car is equipped with a JB4 using our new N55 electronic solenoid control, BMS intake, and 40% E85. As far as we can tell the electronic solenoid uses the same N55 turbo we've all come to know and love but the housing outlet is 4" instead of 3", so perhaps that is helping it flow a little better up top somehow? These are the highest N55 stock turbo power figures I've ever seen. And based on the logs I think the car would have been a little happier with more octane. Things are finally looking up for electronic wastegate cars...

Note that after doing this development we came to the conclusion that the EWG platform is not overly E85 friendly and no longer suggest running more than 30% E85 or higher than map 2 while on E85. To use map 7 and match these dyno numbers we suggest using unleaded racing fuel and/or meth injection.

Really nice numbers.
Sorry for hijacking the Thread. Any chance to retrofit the 4" outlet housing?

Could you add an overlayed graph of pneumatic vs electronic?

what?!? most my car did was 366whp/435wtq...what kind of sorcery is this??

is this because the electronic solenoid 'perform' better than the pneumatic one?

great job!!

Looks like a normal N55 down low and like the Vargas Stage 2 in the first run up top. What will the car perform like with an Vargas Stage 2?

Boost taper looks the same on both N55s. But 435 has more boost between 4500-6000rpm. 335 has more between 2700-4500rpm

Looks like you broke that "oh so difficult" to crack 400whp barrier on the n55 without breaking much of a sweat. Terry with some Merlin sh*t goin on.

Any issues with installing *********? Are they the same **'s as earlier F30's?
Been holding off on ordering them until I saw a 2014 install them.

Is this number only achievable on the newer cars with the electronic wastegates?

Here is a dyno of our 2013 335 vs. the 2014 435. Both running a similarly aggressive tune.

seems like that bigger 4 inch outlet allows the 4 series to have a better top end flowing advantage over the 335i and its 3 inch outlet. impressive!

What about our n55s from MY13 with pneumatic solenoid?
Can we (easily) retrofit to 4" for the extra 20whp?
