    Nice to see some empirical testing. The pressure drop doesn't seem significant.

    I am curious about the small difference in oil temperature between all the configurations. It's very small. Does that mean that the factory oil cooler is not very efficient or that the test was not sufficient to see how the temperature would vary under real world circumstances(street driving)?

    Lastly, what do you do to the pump. I bought a modified one from you guys and compared it (externally) to a spare one I had lying around. They looked identical. I could see no difference in hole size.

    I never logged my data but I do know it off-hand, so here is another setup:

    DUAL external oil coolers (B&M 11”x8”) mounted each at Do-Luck front side-entries, AN10 lines (around 20ft total), oil-filter relocation kit with Canton Racing Oil-Filter - all together 8.5 quarts of oil.
    My oil-pressure is similar to your Test #5 "Oil Filter mounted straight to Block using PHR Oil Filter Union"- peaking at 110PSI+/8000RPM+

    What am I trying to say with this?
    My setup could not be more different than test#5 - and yet we have pretty much identical pressures. So nobody should be concerned if his engine puts out different numbers.

    Thanks for the test however - the actual DELTA-PSI between tests is interesting to know!

    I bought the PHR relocation kit that bolts directly to the block via sandwhich plate, and was also wondering will I have any temp issues driving on the street? From the test it shows that it's only 1 degree difference from the stock cooler to a sandwich plate with relocation kit. Bryan can you give anymore Info on this?

    You will not have any temp issues driving down the street or on the track. What other info would you like?

    For those of you who deleted the factory oil cooler using the relocation kit, did you have to remove the IM to get the stock cooler out of the engine bay or no?

    Yes, I would and possibly the lower intake as well.

    Were you installing the NA or straight to the block?

    Is there any down side to running the filter right to the block?

    No downside except for higher oil temps. No problem for most street cars or drag cars, but I'd install a temp gauge if you can (maybe in the oil pan?). Also keep an eye on oil pressure as it will be higher at cold start up.
