New setup with lowboost (1-1,3bar). Fully forged 2.8L with bw480

Couple pulls:

Still few dozen hp's missing with this boost level, but ignition timing is still relatively mild.

There is pictures of similar solution in this board. "Skarvsladden" or something like that has done it for his ix. Gears are from another diff or you can even buy them new from BMW.

Did quartermile in 10,3s @ 226km/h yesterday with 100% street setup (street tires (nankang ns2), street springs and dampers, street alingments). Finally the stock gearbox broke. Third gear missing now. I think I'll update it to 525ix box (same zf as e36 m3 etc).

Some numbers from engine management log:
0-100km/h 3s
100-200km/h 5.6s
max rpm 8430rpm
max boost 1,5bar

So still with lowboost setup. Will raise it as soon as I get my fuelling updated. 1200cc injectors are 100% open now with two walbro 255lph.

Couple videos:
10,3s @ 226km/h

Little acceleration with lowish boost (2bar) and slow gear changes. Trying not to break everything: :D

Mostly cosmetic changes. Bodywork pretty much all new + new paint.

Technical side - new fuel system and new exhaust. More boost and more revs. :D

Don't know for sure.. Fact is that engine is consuming 20% more fuel than in the best 1/4mile run (10,3s @ 226km/h). I'm guestimating little over 800hp.

Still with lightly modified stock drivetrain. It seems to hold ok, but it cannot take any clutchkicks. I've Limited the torque down to ~700-750nm. 800nm is pretty much absolute max what it can take. Over that and you start breaking stuff with straight torque (front diff, flex disc (between trans and transfercase), transmission, rear driveshaft flexdisc).

Here's few shots of the uncompleted car:
