The current sample car has not modified the cooling exhaust grille, exhausting from the top deck grille like the old CV12-6A power package, but it is understood that the final “Challenger 3” tank will have the same rear cooling exhaust grille as the Omanic Challenger 2.
No, Oman has 8a cooling. 9a will either have the same cooling as 6a or completly new one.
As of now any 9a in existence will have 6a one(unless RBSL did things they do not share).
First of all, the main purpose of the HAAIP project is the “general” power system. Secondly, 9A has a larger turbocharger, higher compression ratio and fuel injection pressure, so the inevitable cooling and heat dissipation system has also been modified. It is reasonable to use a larger hydraulic drive cooling fan device and heat dissipation grille.
It can be understood as: Because the 9A does not modify the heat dissipation cooling system, the power will be maintained at 1200 horsepower to maintain stable operation, or will there be a new cooling system that does not need to modify the back of the hull in the future mass production model?
Some time ago there were 3 options. 1 leave it at 1200, 2 keep te current cooling and with other upgrades and reach 1350, 3 make a new cooling and get 1500. As of currently we have no idea what was chosen.
Well, then wait and see if the new pre-production model will reveal more information (I personally really hope it can have a real 1500 horsepower engine)
From the CV12 TCA MK8A upgrade, it can be seen that compared with the CV12 TCA Mk6A, the Mk8A has a slightly larger turbocharger, a higher compression ratio and fuel injection pressure, and an increased hydraulic drive cooling fan device. Then if 9A wants higher power, the conditions mentioned in the appeal are always indispensable.Moreover, Caterpillar previously said at the IAV2019 conference that it has developed a new Perkins CV12 CR (Common Rail) engine for Challenger 2, which adopts a high-pressure common rail fuel injection system, which improves the output power and reaches 1500 horsepower, so the previous conclusion can be drawn.
