OK. on This steps ill build a twin turbo R8 V8 engine.
1 set engine type, displacement (doesnt seem to affect, the problem occurs anyways)
2 Billet steel crank, i beam titanium conrods and forged pistons
3 set valve type (the type have no effect. In the end the problem is the same for all)
4 Head material I use Cast Iron (i dont know if this is normal, but using Cast Iron the engine gets a bit more power and torque than the other materials)
5 Set compression to 9.0:1 (average compression when use turbo)
6 Set cam profile to 90 (average setting for most engines)
7 Set VVT and VVL (doesnt affect. The problem seems to occur for any type)
8 Set aspiration type (The problem seems to occur only when use turbo)
9 Set the bearing type (I only use ball bearing)
10 Set the bigger (or better ) intercooler
11 Set turbine and compressor size (doesnt seem to affect. The problem occur on any size of each other) But i always set the compressor to the maximum avaiable and the turbine a few mm smaller than the compressor. On this i set the compressor to 67.4 (maximum) and the turbine to 66mm.
12 Set Air Ratio to maximum (1.40)
13 Set Boost to Maximum (3 bar/44.1 PSI)
14 Direct Fuel injectiom, throttle per cylinder and race intake.
15 Fuel type Super unleaded 98
16 Set Fuel Mixture to 10.0:1
17 Set ignition Timing to 100
18 Set RPM limit to 8500 (average limit for high when I use turbo)
19 Set short cast (only avaible if use turbo)
20 Set dual exhaust (if avaiable)
21 No bypass valves
22 Set exhaust diameter to 5.50" (average size for best power and torque results)
23 None catalytic, None Mufflers
All quality was set to maximum on each section
This is the result (no problems ocurred)
Now ill make a fine tune for better results and write all steps again.
This can take some more time.
Sorry for my bad english
