    Air/water intercooler sources

    Any input on sources for an air/water intercoolers? So far Ive found Frozenboost for complete (fully welded/assembled) units, and Garrett has exchanger cores that require full fabrication of both air and water sides. The EBAY ads I've seen have the exact same description as the frozenboost, so I would think its the same company or someone reselling them.

    Frozenboost has really good prices, but not sure about the quality. Does anyone have one they can comment on?

    The Garrett cores I assume to be great quality, but are much more money and will require lots of time and welding to get to a usable point.

    Re: Air/water intercooler sources

    I don't personally have one, but I have seen a lot of guys post that the Frozenboost stuff is good quality.

    Not sure what that is worth, but...

    Re: Air/water intercooler sources

    Precision Turbo has high quality units.

    I am using a Frozenboost intercooler. It's working for me, but I don't know that a name-brand one wouldn't work better.

    Re: Air/water intercooler sources

    What's your power goal?

    AJ used a frozenboost water to air intercooler and then I noticed his intake temp was out of control in the 1/4 mile (over 180F).

    He took it out, installed and air to air intercooler and made more power on the dyno. Not sure where the bottleneck was on his air to water intercooler system was, he didn't want to troubleshoot it.

    i run the frozenboost set up here too and the quality isn't top notch but it does work. So far I haven't ever had problems.

    Re: Air/water intercooler sources

    It should be noted that Frozenboost offers many different sizes and configurations. They have different horsepower ratings... although the method at which these ratings are assigned is unknown. I was advised by the fast guys that use them to get one rated for twice the power I intended to make, so I got a type 5 "rated at 1200" hp.

    Re: Air/water intercooler sources

    I was going to mention AJ's experience with Frozenboost. I will also say that others seem to run their stuff with decent results, but I don't know if they are actually datalogging the IAT's. Warren Hall swapped out his Frozenboost core to a Bell core and noted a significant improvement in heat rejection. Just something to keep in mind...

    Re: Air/water intercooler sources

    I cannot recall the specific conditions at drag day at SDAC 28, but with the turbo sucking hot underhood air, my charge temp through the traps was 108 degrees at 24psi.

    I think Warren's concern was more with pressure drop. He had some high numbers with this Frozenboost intercooler.

    Re: Air/water intercooler sources

    Thanks for all the good info so far.

    Guess I should have stated my goals up front. It will be a 2.4l/ 5 speed and hoping to tune it to about 300+Hp. It will be street driven and probably never see a track of any kind. Basically my set up will go from the turbo, turn 90 degrees into this: http://www.frozenboost.com/air_water...ler-p-209.html and 90 again straight into the intake. There is a nearly identical set up being built in the project forum.

    If what has been mentioned is true, they have a 4.5" core set up for the same price rated at 600 hp so that would probably be the way to go. As stated by someone else I don't know where they get those numbers from. I have enough invested in the air/water plan that I intend to see it through. The only part really left to purchase is the actual air cooler.

At around 30psi on a GT3040 I was getting 120-125degF temp drop but around 3psi of pressure drop, and 125degF intake temps (measured using type K thermocouples on a 50 degree day with 85degF water temps).

    I replaced the Frozenboost I/C with a custom A/W IC with a Bell core (6" x 5.3" x 12"), and on a 90 degree day in Memphis with about 25psi of boost and saw over 200 degF temperature drops and 140degF intake temps even with 126degF water temps. Unfortunately my pressure sensors have not been working so I haven't been able to log pressure drops yet.

    Just some data points, but the larger Bell core cools SIGNIFICANTLY better than the Frozenboost cooler did.

With an air to air it took probably the same amount of re-engineering (spent 50-60 hours one week on it) but also freed up a lot of space in my engine compartment. Plus the air to air is proven so I went that route.

    Warren's improvements in cooling are certainly significant, even when you consider that the Bell core was nearly twice the size of the Frozenboost core it replaced. It will be interesting to see the improvements in pressure drop as well when the data becomes available.

    Re: Air/water intercooler sources

    do you guys think laying the air to water intercooler on it's side would have any negative effect?

    thinking there would be A LOT of space over the trans, inner fender and 2/3's of the battery tray (with a small battery pushed flat against the smec)
    this would allow a much bigger a-w intercooler than trying to put it in the o-e filter location

    and then I still get to use the factory air filter location next to the head to build an open top filter box that feeds from a simple hood scoop

    I could also then eliminate the 90* bend with two 45's and a tube going into the throttle body as the inlet tube would be much closer to the strut tower

    As long as it is oriented and plumbed so that it would not trap air, I don't think it should matter.

    a bung and a plug right on top should solve any bubble issues I'd think

    yup. As long as it's a closed system.

    Re: Air/water intercooler sources

    adding an easter egg
    the small battery I found is 6" long, 5" tall and 3' wide
    rated either for 700 or 780 CCA

    lightweight lithium at 3 ish pounds

    it's not cheep at 400 plus and a charger for 50 bucks but I think it will make up for the weight of the a-w cooler beside it ok

    brand name is Antigravity

    they make bike batteries but the 700 and 780 are for race cars

    Re: Air/water intercooler sources

    Like tryingbe said, I ran a Frozen Boost AWIC that was "suppose" to be good for 600 hp and at 340 hp I was seeing 180*-200* temps by the end of the 1/4 mile track. I would say cut whatever horse power rating they are advertising in half and you'll be closer to accurate. My new air to air Treadstone 1000 hp IC is 20*-40* cooler on a day that had 20* hotter ambient air temps and I picked up 26 hp and 20 ft/lbs of torque.

    On a side note, I was very happy with the around town results, just not at the track.

    If you do get one, a couple of tips for plumbing, make sure the pump is the lowest point in the system and have the pump push through the intercooler directly, nothing in between the IC and pump. Also any high spots, have a bleed that goes back to the reservoir. It makes bleeding the system easier.

    CX racing also has AWICs and they are close to the same price or better than Frozen Boost. https://www.cxracing.com/liquid-to-air-intercooler-pump

    Re: Air/water intercooler sources

    Pics of fill/air bleed tank set up. Tank in upper left corner of first pic. Pump is located with exchanger at bumper. Barb for 3/8" hose to air bleed/fill tank at top of IC is seen near turbo intake on side of IC in second pic. A 3/8" tee in the 3/4" coolant hose connects to the other side of the bleed/fill tank. After a half hour of running, coolant in bleed tank runs clear, bubble free.

    AJ, I wonder if pump flow rate could have been an issue.

    I ran a test; through the IC and the exchanger got 12 gallons/minute at 15 volts. More pics attached.

    Edit - I reviewed AJs build thread and see that he used a plate cooler too. AJ, somehow I missed it's purpose?

    I ran the Bosch cobra pump. I installed a higher flowing water pump and cooling went down, my intake air temp went up. This is the pump I "upgraded" to: https://www.summitracing.com/parts/l...iABEgIe4vD_BwE
    It did flow flow more, I did a back to back test. I ended up putting the Bosch pump back in. After I wasted $200+ dollars on this pump I decided I wasn't going to invest anymore into trying to find out what my lack of cooling problem was.
