    300 Stock closed loop

    Can the stock cooling system handle 8800rpms? Will the water pump survive?

    I think Sanfish has commented about this in another thread. I'll let him confirm but I believe he had to go open Loop at that high of an rpm (but prefers closed loop if he had the choice). May be a temperature thing spinning that high (requiring open Loop). Let's let him chime in to confirm though....

    To be fair, my (260) findings may not apply to the 300's as the cooling system has changed a good amount and internal pressures could be different.

    So ---->
