Power steering pump issues

[CarlC]

That's not from pressure, it's from heat generation. High pump speed combined with a pump liner suited for comfy street/OE purposes does not usually work well at the track. It's the sustained high engine speed + large pump voulme that causes the problem.

Just adding a cooler has not always been effective.



A stock P-type pump can be modified to have a smaller pump liner and output pressure reset. It can also be modified to run dry using a remote reservoir. Removing the reservoir has shown temperature reductions of up to 80* according to Lee's. This is a good option for those still running the Chevy short waterpumps since the aftermarket TC-type pumps do not fit well.
