Great news, all of this. And excellent work, from all parties - kudos to Tony for getting all of this research and development done, we'll all profit from this. An excellent new choice has been given to us N54 owners!
And yes, I can personally attest that this stage 2 equipped car is monstrously fast.
Saying that when driving a 400+hp car myself is quite a statement, I would imagine. Flooring it in any gear and Tony just whisked away from anyone on his tail. Just a pity that the weather on the 'Ring was not ideal for such torque-monsters. Roll on 22/23 May!
And I'm already saving up for my stage 2 turbos that should be @TurboDynamics at the moment, even though I haven't heard from Martin until today. I will certainly have them installed at Birds, just like my Quaife - always nice to have an excuse for a trip to London!
