    Alright, here is all of the test data from the individual D5 Aftermarket top tests in one chart per speed setting...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.

    • 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

    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

    Is there a reason why you did not include the Bitspower D5 top.

    I am not sure what you are asking. :confused:

    I have not heard from Bitspower since I spoke up about the major restriction and pressure loss on their mosfet blocks. Since that time all communication has gone un-answered. Additionally, I have not seen Vincent post anywhere since Chinese new year either.

    Vincent is still around I have received a few emails from him. The Chinese New Year is probably responsible for the lack of forum contact. I must admit I was looking forward to the Bitspower D5 top testing.

    Oh, the official skinneelabs safety officer. Yes, he is always involved reminding me to turn on the pump, etc.

    He keeps me on the straight and narrow. :D

    This makes me feel a little better about getting the EK Top and using the front outlet now :)

    Cant wait to get paid and for GAM to get stock

    I used the EK and front outlet for my radiator testing. That setup worked the best for how I needed to route the tubing.

    Also, since only us crazy bacon cheeseburger loving Yankees use GPM and PSI I will be posting any future flow and pressure tests in LPH and kPa/mH2O. Sorry for making you all do the extra math.

    Wow, what an incredible amount of work!!! Great effort.

    Do you offer commentary or is it as straightforward as it looks - i.e. higher is better?

    PS. I think plenty of us would prefer cheeseburgeresque imperial measurements when it comes to pressure lol.

    I usually do a full write-up for each individual part, for the comparisons I tend to just present the data, numbers explanation and test methods. I link to the individual reviews...but I am usually so sick of looking at the parts I can't type anymore about them and keep that cheery tone that is required.

    GPM and PSI are ok, or LPH and PSI?
