    • AMS releases 2017 on Porsche 911 (991.2) 9A2 3.0 Alpha Performance upgraded intercooler system

      AMS released their upgraded intercoolers for the Porsche 991.2 as if right on cue. With more and more tuning taking place thanks to the ECU unlock the cars are quickly getting heat soaked when pushed. One tuner told Porscheboost they will not offer their Stage 2 tune without intercoolers.


      Fortunately, AMS offers a solution. The Alpha Performance Porsche 991.2 Carrera Intercooler System features cores 50% larger than stock.

      The cores are 120mm thick and offer a fin density of 20 fins per inch.

      They also include carbon fiber intercooler ducts:

      Our engineering team designed the Alpha 991.2 Intercooler end tanks with extremely smooth features and the perfect geometry for the best flow resulting in maximum horsepower. Designed using Solidworks 3D CAD software, these end tanks have improved flow over boxy sheet metal end tanks found on other intercoolers. We then took it one step further. AMS Engineers designed the organically shaped carbon fiber ducting to make use of every millimeter of available space for the ultimate power producing charge of cool air. The organic carbon fiber lower ducts allow the heat to transfer to atmosphere instead of soaking into the intercoolers.

      Channeling cool air to the intercoolers is vital for optimum performance of any intercooler. Some manufacturers choose to remove the factory intercooler inlets in order to cut costs. This greatly reduces the effectiveness of ANY intercooler whether it’s larger or not. Others require that you cut up and tape the factory shrouding to the intercooler core in an attempt to seal the shroud to the intercooler core. While this is better than removing the shroud, it is still not the most effective way to boost performance. The Alpha Performance Intercooler kit requires no drilling and no cutting.

      The Alpha 991.2 Intercooler System retains full use of the stock intercooler inlets forcing cool air into our larger, carbon fiber shrouds. Not only is this option more aesthetically pleasing, each rigid OEM-quality carbon fiber piece is made to seamlessly mate to the Alpha Intercoolers feeding them cooler ambient air more efficiently than the alternatives. Not to mention, eliminating the removal or destruction of your intercooler ducting. Included with the kit are velcro Alpha branded “speed straps” that hold the lower duct securely to the upper duct that will not deteriorate over time.

      We do not disagree with any of that and PorscheBoost definitely intends to explore this option for the PorscheBoost.com Project 991.2. We just wish there was more data to accompany this release as AMS provided with their 997.2 Turbo intercooler release.

      For $2899.95 potential buyers definitely want to see as much data as possible before pulling the trigger. It is certain the factory system is already being overwhelmed with aggressive tuning as PorscheBoost saw in its own testing.

        Well this is exciting. Others will no doubt be closely following like awe, etc

        Wondering what the gains are on the maxed out stock turbos...

        This looks like a good upgrade for anyone thats going to be pushing the stock turbos.

        Im not thrilled about the connection and securing method of the CF ducting onto the IC core... Velcro straps? Seems like there has to be a better way to do it?

        I thought the velcro straps was pretty ingenious. The carbon fiber duct weighs about nothing and the air pressures at the duct to IC interface is probably no greater than ambient pressure, so no real tight seal really required. Optionally, you could use safety wire, just have to do something to fortify the carbon fiber so the wire doesn't cut through it over time due to vibrations, etc.

        Great to know it's available for power hungry folks....I do also hope AMS has big plan for their 911. Can't wait!

        Exactly this. Also people in warm areas.

        Gintani said the car heat soaks pretty badly on race gas.

        VF says their Stage I tune is just fine all day but Stage II needs IC's.

        I wonder how long this install takes, my guess is probably 5 or 6 hours from a shop. It doesn't look particularly difficult, but just very tedious with a lot of steps.

        At least you can do the BMC air filter at the same time!

        Yeah, thats the same link I put in my earlier post, but when I went down through the steps, I didnt see an estimated install time.

        I was speaking with an engineer that designed upgraded intercoolers for the 9A2 3.0 and mentioned the AMS upgrade and what he thought about it.

        Now, I don't know the engineering here or why the design works or doesn't work. What he said is that the AMS design just isn't good.

        It will work as a heat sink and recovery rates will take a while.

        Is this true? I don't know but he knows his stuff and I certainly want to show off his design (I have some photos but can't post yet) ASAP. This is why we need data or independent testing.

        Interested to know what he means by "the AMS design". Looks to me like a similar design as stock/oem with just a larger core with larger carbon fiber shroud....

        very interested to see his advanced engineering design that will out perform Porsche oem design.

        Don't be surprised when you do...

        It will prolly weigh more too? but then I guess the torque/power dpt will make it for it.

        I want to see a PDK 991.2 carrera with tune + bypass pipes + intercooler race against a 997.2 or 991 Turbo

        Perhaps he's referring to the cast aluminum end tanks? I don't know their thickness, but I wouldn't think they would hold much that much heat compared to plastic.
