We also ran extra electric water pumps to cycle the coolant at a higher flow rate. Running a larger radiator or larger volume of fluid proportional to the engine water pump flow rate hides the problem, but as you explain it adds weight as each litre of coolant is extra kg. Plus you multiple the water hammer effect with the rear mount radiator being to big under G. We ran ours behind the rear tires, like a lambo after going with the original in the boot that blew the water pump. As we could flow the coolant independently of engine speed.
Yes. I know that that mid-engine cars with the radiators up front can get cavitation at the pump. Factory pumps were just not designed to move this much water mass.
Yes with mid/rear engined cars the G under braking isn't as bad as it's pulling from the pipe. But the rear mounted acts like a trebuchet if you pull 2-4g under braking having the same size radiator volume, pipe diameter, angle all multiplies your problem. If you build it to not break at that load, then you lack flow the rest of the time. Hence our switch to a reservoir then t off multiple stages, like fuel it's easier to stack systems and switch a pump on at temp and then increase flow rate/fan speed, then open another or a third if required as you will know the envelope of the system better.

Looking forward to see what kind of aero gain you get, and what are changes you guys will make to the front for more DF.
If only Bernoulli could see just how crucial his principle still is centuries later. It shows up in soooo many different automotive systems.
his family makes a decent pasta
This is good stuff, thank you
very cool work you are doing...
Thanks for sharing
Very interesting. Can you tell what kind of core are you using, fpi?
*Feras has entered the chat*
Is there any chance we can get more information about the rocket anti-lag?
The fastest time attack car, the rp968, has it mounted in the front horizontally.
why do you guys run a trunk spoiler or duck tail with the frame mount wing ?
What are you doing for intercooler?
