What sort of performance are we expecting? (without NOS) I would have thought 400 (real) bhp should be on the cards given that a healthy standard 'S' model gets about 380. Should have some nice torque too.
i asked the same question and they had no idea what so ever. Its a healty increase in engine size though. i would imagine that 420 to 430 would be in easy reach and a engine built like that would be happy taking a 100bhp shot of nos. will be very interesting to say the least
