FERRARI and Renault never had a split turbo (with MGU-H in-between the compressor and turbine) and with the compressor in the VEE.their set-up certainly doesnt show any disadvantages to the split system mercedes adopted.
I was wrong. Thank you for correcting me.
Even has some advantages:
-minimal Pu CofG is easier to achieve. Heck design for gearbox or clutched systems could be much easier to implement if wanted.
-pretty much no serious size restrictions on turbo size
-pretty much clean V-ee of the engine. More potential for compacts VLIM or more "optimized" intake plenums. I dont think that is really the case. But if engine engineer want more volume he definitely have easier job.
-shorter turbo shaft-less moment of inertia
Dissadvantages:
-complex intake piping for turbo and intercooler,
-all that air piping is a little longer, hence some more losses there
-packaging is bulkier all around PU. especially on top end and on backside of the engine.
At least i think you have pretty much more sacrifices in term of packaging. Or at least you have much complex ducting all around, so till now Ferrari use much more man hours in that area than Merc for example, sure. So i would also say suma sumarum Ferrari system is harder to design but it doesn't bring so big disadvantage to ditch it. At least now when you had 6th iteration of design roadmap. It doesnt bring much sense. At least for my untrained eye.
