    New IC's tested!!!

    So finally got some own time in the garage, work has seriously interfered with my private life lately.


    So short summary, swapped the stock 997.1 for the 997.2 aka GT2RS IC's, this turned out to be seriously much simpler than expected after reading DIY's online (most are for 996's and the fit is worse for those cars). Basically I used a sharp knife and cut 4 slots for the new wider core and then cut some of the plastic away from the plastic strips that snaps it all together.


    I can do this conversion in 15min per IC, it is that simple...maybe a bit "ghetto" but seriously ok imo, I will never use the stock 997.1 IC's ever again (and you shouldn't either).


    So datalogs, the Cobb makes this so easy, did the same 3rd gear pull in the exact same location (slight uphill stretch of "autobahn" on my way to work). Temperatures slightly higher today than last time with the old IC's. Car slightly more heat soaked due to sitting still in traffic just before doing the pull.


    997.1 IC's pull (3rd gear)
    Ambient temp = 48.2F
    IAT before pull = 57.7F
    IAT at 5000rpm = 61.7F
    IAT after pull = 91.4F
    Diff about 30F


    997.2 IC's pull (3rd gear)
    Ambient temp = 61.7F (+14F)
    IAT before pull = 76.6F (+9F)
    IAT at 5000rpm = 73.9F (+13F note the new IC's managed to lower iat's during this part of the pull!)
    IAT after pull = 83.3F (-8F)
    Diff about 10F (-20F)


    So even though it was warmer, and the car started the pull with much warmer iat's, in the exact same location, using the same map, same load and boost, the new IC's are doing a much much better jobb of cooling air.


    Since they are good and cheap I think they are the best value for stock frame turbos, not even sure I seen any test where they didn't "win".

    Only going from 77F to 83F after a decent pull is really good... with ambient temps outside = 85F I have been hitting 110-113F with the 996TTS.

    This is good data showing they are making a big difference. Ambient temps warmer but the temps after the pull cooler? Yeah, the 997.2 IC's are doing their job.

    There is an ancient argument about how restrictive they are compared to $5k IC's (which they prob are) but they are better flowing than 996/997.1 (better core and end tanks).

    They are great value in p-car tuning!

    Excellent results and right on par with what we're seeing on our 997.1 and the 997.2 FMICs on it. Porsche certainly did their homework here.

    The lat log had some throttle closures so Mitch wanted to give me an updated map, so now its running smoother and faster. It feels great and loosing the cats made it sound wicked!

    That is really smoking quick given the mods, similar to DZenno@PTF car and we know you usually do pulls up hill Click here to enlarge

    I did a 3.2s 60-100 mph today which is my quickest ever but the silly box says it is invalid cause I had a 2.02% downslope Click here to enlarge My 50-100 mph is > 4.1s at best

    Dzenno pointed me to vboxtools.com, great site, no more running a virtual Win7 just to read those vbox files Click here to enlarge of course my fastest run wasn't one of the vbox recorded ones. But I had a 3.35 60-100mph going....wait for it....1.35% UPHILL Click here to enlarge

    Need to find at least one stretch of road that isnt uphill, maybe this one can be used going towards the city instead, should be downhill then, but with my luck it is probably uphill in both directions...

    that 2.02% slope, can't you use a slightly different part of road to get a perfect 2%?

    Yeah, I don't really care but with summer traffic out here I try to go to very quiet safe spots. I think I am maxxed out apart from WG and new ICs, aim to is to get to McLaren 12c times 100-200 kmh, 60-100 mph etc
