Few questions regarding the v12tt
Im looking a picking up a sl600. I will be modifying it quite a bit as i cant leave anything stock. I have some questions that are hard to find a direct answer:
1) does the v12 indeed have forged pistons?
2) has anyone tried clipping the turbine wheels on the turbochargers to increase flow and reduce drive pressure and reversion?
3) what are actual size of the oem injectors?
4) are the factory o2 sensors narrowband (0-1v) or wideband (0-5v)?
5)does anyone know (tuners chime in here) if the mafs operate in series or parallel?
6) what parameters trigger overboost cel? (Ie. maf voltage or map voltage)
7) has anyone actually logged drive pressure:boost pressure ratio?

Don't believe the 600 has forged pistons.
2) has anyone tried clipping the turbine wheels on the turbochargers to increase flow and reduce drive pressure and reversion?
The modificiation is typically to machine the turbo to accept a larger wheel for more boost.
5)does anyone know (tuners chime in here) if the mafs operate in series or parallel?
Neither, it runs MAP.
6) what parameters trigger overboost cel? (Ie. maf voltage or map voltage)
Boost is controlled electronically.
7) has anyone actually logged drive pressure:boost pressure ratio?
Many have data logged.

Blown, thanks for a quick reply and input. I would still like others input as well. In regards to #6, id like more info on the resolution of the map (ie. 4 bar, 5 bar). Any extra info on any other # is appreciated.
I have some modifications planned out if i pick the sl600 up.
