So, Jerry came to us with a pretty cool request: get the IATs down, keep them down, and turn the wick up! While upgraded stock location air-to-air intercoolers was a no-brainer, Jerry had an even better idea — integrate an auxiliary water-to-air intercooler system. With no off-the-shelf product to turn to, Jeremy got to work custom fabricating the water-to-air intercooler system — custom FLUIDYNE High Performance heat exchanger, turbocharger intakes, cold-side Y-pipe with integrated intercoolers, “frunk” mounted intercooler reservoir, properly spec’d intercooler pump, routing the intercooler fluid hoses along the OEM hoses & fabricating protective guards across exposed areas, and all the wiring & odds-and-ends to bring it all together.
With the stock location air-to-air intercoolers installed, water-to-air intercooler system fabricated, we strapped the 997.1 down on the dyno to put it all to the test. The results? Well, check out plot 4 in the attached datalog screenshot: with ambient temperature of 67.77° F (see dyno graph for conditions), IATs at the beginning of the pull were 45.90° F, and only increased to 59.40° F by end of the pull — an increase of only 13.50° F throughout the run, without any ice in the reservoir!
The real question, is how does this translate to performance? Stock 997.1 Turbo Tiptronics normally lay down around 400awhp & 440lbft on our dyno, and with Vlad calibrating via COBB Tuning‘s Accessport, he was able to increase output to 558.17awhp & 585.05lbft — an increase of ~158awhp & ~145lbft! Overall, killer results for this unique project. We can’t wait to hear Jerry’s results at the strip!
