Alright, here is what you have all been waiting for...I'm not going to muck all this up with details, you can find the full write-up on my site, skinnee labs D5 Top comparison.
A look at the contenders.
Test Methodology
The pump testing loop is a completely separate loop on the test bench. The pump test loop is comprised of a custom built half gallon PVC reservoir, and gate valve for controlling flow. Bitspower 1/2" High-Flow fittings were used for consistency across all D5 pump top tests. I use an assortment of measurement tools for pump testing, here is the list.
For each configuration tested, the loop was bled and ran for 20 minutes prior to measurements taken. After 20 minutes, power to the pump was shutoff, and the Manometer was reset to zero PSI. This step ensures a proper measurement of the total dynamic pressure for the pump is recorded. Voltage is adjusted to 12.00 volts in order to achieve a constant voltage across all tests, voltage was verified prior to the 2 minute runtime and verified before measurements were recorded. Also to eliminate and pressure variation, each flow setting was , given a 2 minute runtime before measurements were recorded. For each flow setting the PSI, Voltage and Amperage are recorded.
Test Results
And there you have it, all the compiled data. Thanks for reading!

- Power: Mastech HY3005D (0-30V, 0-5A) Variable DC Power Supply
- Volt/Amp Measurement: Fluke 23 Series II Digital Multimeter
- Flow: King Instruments 7520 Rotameter, 0.5-5 GPM, 10" Scale
- Flow Control: 3/4" Inlet-Outlet Gate Valve.
- Pressure: Dwyer 490-3 Hydronic (Wet/Wet) Digital Manometer 0.00-50.00 PSI
