I don't think you can say any of those things are necessarily 'worse'. Most of the comments I've seen on the pull-rod say it doesn't really make a huge difference (although initially it was thought it could be of some benefit, with the general opinion now being the opposite - but nothing for sure), but it could be that going inwash and having the pull-rod are actually tied together, with the 'slight aero benefit' we've always been told about becoming more pronounced if much more of the air is being routed inside the front wheels).medeni73 wrote:So if rumours are true Ferrari will have pull-rod instead of push-rod, in-wash instead of out-wash and water-air cooling system instead of just air cooling system, all of those 3 things experts are currently saying are worse than opposite solutions (push-rod, in-wash and air cooling system)...
I hope either experts or those rumours are wrong
What if you share the circuit for the coolant for engine and intercooler?dren wrote:The intercooler is not included in the power unit weight requirement.
They'll probably install the engine radiator and the intercooler in different pods. Apart from that, why limit heat exchange capacity? Which one would transfer heat from the coolant in first instance and which one would be sacrificed?Mr.G wrote:What if you share the circuit for the coolant for engine and intercooler?dren wrote:The intercooler is not included in the power unit weight requirement.
So you've just made it an interwarmer?Mr.G wrote:What if you share the circuit for the coolant for engine and intercooler?dren wrote:The intercooler is not included in the power unit weight requirement.
That layout is used in some engines. Coolant is cool in comparison with compressed intake air. Usually you can cool that air more by using air to air heat exchanger and fresh air. Water cooling tends to be more compact an easier to pack.PhillipM wrote:So you've just made it an interwarmer?Mr.G wrote:What if you share the circuit for the coolant for engine and intercooler?dren wrote:The intercooler is not included in the power unit weight requirement.
Yes, might happen but we are talking of a F1 engine going at 15k rpm with a turbo up to 125k rpm. All and All to achieve the same heat transfer rate, increasing the heat transferred you will need more mass of fluid. The temperature differential enters the equation.dr_cooke wrote:

Sure, it would not be very efficient, but I mean it would still be an intercooler, not an "interwarmer" as was mentionedPhillipM wrote:In an F1 engine running 125*c coolant temps?dr_cooke wrote:Coolant is cool in comparison with compressed intake air.
I don't buy it, I can't see why anyone would run a water/air when there's already coolant hose routes to the radiators so packaging for air/air isn't an issue, and the turbo is spooled by the MGU so there's no lag to worry about.
