    ZZP vs FrozenBoost FMHE

    I'm looking to add the additional heat exchanger as many have done on here. I see a few people with the frozenboost 101 and others with the ZZP unit.

    The ZZP unit appears to be 2-pass according to the website, but from others I've seen on the internet, it looks like its a single pass. Reading the website, it can be ordered in either configuration.

    Its dimensions are:
    27 3/4" wide x 6 1/4" height x 2 1/16" thick


    The Frozenboost certainly has both fittings on the same side, and is a 2-pass.

    Its dimensions are:
    26" wide x 7" height x 3.5" thick

    All in all, will these perform equally, and will any difference even be worth considering?

    Code:
               Width     Height   Thick
    ZZP        27.75      6.25     2.0

    With either one the big difference is the cooling aspect. Or should I say the time it takes to get from WOT to normal temps.

    PGA, do you recommend the ports being on the same side for ease of install?

    It does make it easier. It is a personal preference. I have the Flex-A-Lite 45321 (6 pass) that replaced the stock and added the Frozen Boost 101. Living in AZ I haven't had any issues in the summer heat. I usually run 20-30* above ambient for IAT2 temps but I can run back to back WOT runs within a minute of each other with the upgraded pump. The temps drop really fast and are back to normal within a minute.

    Good to know. I'm going to just run the frozenboost unit for flexibility, and so I don't have that silly ZZP logo painted on there. (Also saves a few extra bucks) Thanks for the tips.
