    Starting this thread as an outpost for technical data on the avail intercoolers.

    I will update as new info/products are offered.

    The core dimensions are taken by the posted manufacturer specs. If you own one of these and find the measurements in the real world are different, please let me know!

    Some more data around my Airtec FMIC upgrade.

    Here is a 4th and 5th gear to about 5000rpm hwy WOT pull.

    It was 95F out at the time.

    Charge temp
    Start - 100F
    End - 105F

    Intake temp
    Start - 98.5F
    End - 97.5F

    very impressive results with the Airtec FMIC! This weekend I wrapped the induction tube with silver and gold heat resistant foil, wrapped a section of the cool pressure tube near the block, and sealed off the sides of the intercooler to the bumper. The results with the stock intercooler show a 15'F increase over ambiant with a 2nd and 3rd gear pull at 21psi. A 23.00psi 6th gear pull ends up with a 20'F increase over ambiant, with that happening pretty quickly under acceleration. Even with the improvements to protecting the air supply from heat and working on increasing the amount of air going thru the stock intercooler, the data continually points to needing an upgraded FMIC. It is great to see actual data being posted! Great job, Razorlab.

    Old post but curious if weights of each are known? The Airtec has been reported as about 3-4 times heavier than stock.

    When upgrading your Fmic, is it imperative that you replace all piping as well? I have read places that upgrading the hot side charge pipe is all that's really necessary. Please help, or direct me to help. Thanks!

    Last week I order a mishimotos jline intercooler. After weeks of researching I found this to be the best bang for your buck if you don't mind a little engineering to put that in place. It is a heavy intercooler then the rest of the competition though. Another intercooler that I heard good things about is deadhooks intercooler.

    I would love to know pressure drop for each of them.

    Mishimoto and cp-e have lots of data about pressure drop. Mishimoto was like 0.75 psi and cp-e was less than 1 psi too. Deadhook might have like 1.5 psi maybe but it's not from direct measurement.

    Forge motorsport claims 0.9psi.

    If this is to become a reference thread, do we know which ones are essentially a direct fit and which ones require additional work?

    Does anyone have any information regarding Treadstone Performance Intercoolers out of Florida?
