Does This Debunk the "Coolant Can Flow Through the Radiator Too Fast" Idea???
I don't see how the pully ratio changes with rpm. At a given engine rpm the pump rpm will change with different pully ratios.
But it’s always 30% (or whatever the pulley ratio is as I’m only using 30 over as an example.
30% over at 1000 rpm is 1300 rpm PUMP SPEED at idle.
At 6000 PUMP SPEED is 7800.
At 10,000 rpm the PUMP SPEED is 13,000 rpm.
At some rpm the pump will be spinning faster than it can handle. Is it 10,000 pump rpm or is it lower?
I don’t know but I do know you can over speed the pump.
Let’s say 8000 rpm is all the pump can do (pump speed). And you are shifting at 9500. And the pump is is even 10% over driven, you can see how you’d have to slow the pump down.
My point is you can over speed the pump.
My math comes from using the over drive numbers in the FSM and the max rpm that engine ran.
If you think I’m wrong, show the math. I get tired of explaining what simple math over and over.
I’ll say it again, the pump can be over driven but AFAIK it’s hard to do unless you are running a ton of rpm.
It’s not hard to grasp.
It’s no different than getting the overdrive of a blower to match engine rpm.
