Mission 400 Plus...speaking of turbo engine reliability
Top speed: over 400 kph.
Power: aprox. 1055 HP (3.8 l "Turbo" engine)
Torque: 1250 Nm
Right, this is a concept car but it shows what a good engine Tuner can do if the basis is right.
It also shows the close relationship between H&R, Jürgen Alzen Motorsport and RS-Tuning.
Of course this engine has been modded a lot and it isn't using VTG chargers but it shows what potential it has.
We're talking about 1055 HP without NoS or other "gimmicks".
