RE-medy - Is it better?
I purchased one of these pumps and recorded flow and pressure data of both the stock and supposedly improved RE-medy pump. The tests were done at a 200F operating temp and without a thermostat.
The stock pump pushed fluid at higher rates across the range of my tests. At 8000 RPM and 0 restriction, the stock pump pushed 37 GPM compared to 27 GPM for the RE-medy. At the maximum restriction that I tested, the stock pump pushed 20.6 GPM compared to 16.6 GPM for the RE-medy. Just food for thought for those considering the swap. If a company is unwilling or unable to provide scientific data to support their claims, there may be a reason. A company generally provides a pump curve for any legitimately designed pump. The RE-medy impeller certainly looks like an improvement compared to the stock design but my testing did not show that to be true. Does anyone else have any data or is there any other testing on water pump flow rates and pressure for the Rotary or specifically the Renesis? |
The main advantage of the remedy pump is elimination of the cavitation that occurs at sustained high rpm with the stock pump. I am putting in a new radiator on my 2008 RX8 and I am installing a new remedy pump to go along with the remedy lower-temp thermostat I already have.

Remember when I simulated them a couple years ago? It's still on this forum somewhere. |

If this was a custom bench bench-top system:
In either case:
I'm not trying to be confrontational or cast doubt on your results. I just need more information to properly evaluate your claims. |
I'm also curious as to what you used to measure the flow rate.
