In my mind I still think that there is a possibility that the turbo have been ‘split’ and I will explain why. From before the very beginning of this polemic on F1 media the by far majority of those expressing their opinion was always that the split turbo system as originally explored by Mercedes was the most advantageous. And among these at the front were the usual half-a-dozen or so F1 media experts that not only drove/pushed that out, but are the most that influence their followers and others looking to form an opinion. Comes the confirmation that Honda split their turbo, and those experts opinion pushers got a boost in popularity. Next came the confirmation of Renault having decided to go the split turbo way, and that added some more boost to the experts push-out. Up to that point, the usual race for pole between said experts was only about pole and not for who was right or wrong. The last to come out was the 066/7 turbo configuration chose. But this time the race of said experts for pole was all about who is first and right or wrong. Most saying its split and some saying its not, all with pretended inside information. It might well be that this time those claiming non split had tripped in their race to be the best and first informed. Why am I saying all this?, because the only thing out of FERRARI, although right now I don’t remember when and where I read it, FERRARI hinted that although they did not chose to go the split turbo architecture way of Mercedes/Honda way (compressor at front of engine and turbine at rear with ‘H’ in between), they this time they placed their compressor inside the air box. So it might be that FERRARI did split their turbo, but did not follow Mercedes/Honda architecture. If FERRARI kept their previous turbo architecture, with compressor in-between turbine and ‘H’, they would have had to also put the ‘H’ inside the air box.
