+1 Thanks Scarbs.
the Renault PU package and cooling* would be majorly revised
IMO turbo layout wont change a lot. According to Taffin, the 015 PU was still running a classic layout until September. Do you think Renault make such a change (move to a split turbo layout) in just 5 months? I doubt it. Unless Taffin was 'sandbagging'... but why would he?
If turbo doesn't change, MGUH position do not need to be changed... unless Renault decides to place the H between the compressor and the tubine like ferrari for example in order to put a Ferrari like 'V' intercooler* betwwen the heads, closer to the turbo ?
MGUK position wont change IMO.
Battery shape will change according to Espimperium as well as the engine's oil tank.
What about the control units?
*What if STR switches the engine oil rads and intercooler water rad positions: place the engine oil rads in the sidepods (low and backwards where the 2014 air-air intercoolers used to sit) and put the intercooler's water rads up there? : P
