Again, I'd love to know if there's any meaningful difference betweenThe variable flow restrictor, is more to stop cavitation and the resulting core erosion that goes along with it.
One would surmise that the size of restriction needed at high engine speeds in the LT1, would seriously affect heat output at low RpM, hence the variable part. Also to dampen shock from abrupt speed changes.

because I can't see any meaningful difference.
That said, I agree completely with, and stipulate to, the above quote; it makes more than enough sense, that I cannot think of another reason.
Having operated an HDMeziere on my previous wagon for several years, I stipulate to this as well, if only to add something obvious: any given LT1 electric H2Opump operates at its own fixed flowrate. Since the restrictor is meant to dampen changes in flowrate, it is pointless to use the restrictor with any of the electric H2Opumps.Not an issue with electric.
Also, the electric pumps do not flow as much as the LT1 mech at full song, so I would tend to agree with 1slow96' thoughts about the restrictors merit with electric.
Gerry, it's your world. We all just live in it. ? ?Think of this but in reverse when thinking of coolant speed and heat transfer.
No. But a lot of people still think so. We have come up with some explanations for the Doubting Thomas. Debunking the I Can Have It Both Ways Theory The water has to have "time to cool" argument is perhaps the most common one we hear. In a closed loop system if you keep the fluid in the heat...www.flowkoolerwaterpumps.com
In my world we run pumps slower to reduce cavitation and to reduce parasitic power loss.
