Cobalt 2.0 Performance

Now with Cast End Tanks!

We didn't have to go much further than our popular Solstice/Sky intercooler to design this exciting new version for Cobalt SS-TC. Using our purpose-built and designed cooling core (a Hahn exclusive!) provided a proven solution, one not limited by choosing some "off-the-shelf" universal core. This core features a whopping 835 cubic inches of volume!

And now, we've now also added CFD-designed cast and polished aluminum end tanks (not pictured yet). They are carefully engineered to augment airflow while avoiding turbulence and 'dead spots'. Computational Fluid Dynamics (CFD) allows our engineers to perfectly simulate tank internal airflow characteristics for a perfect result every time. You'll love the smooth look and exceptional performance!

For a well-engineered finishing touch, we retained the OEM mounting brackets and their beneficial rubber isolator mounts.

The largest unit available, with 28% more core volume than the nearest competitor, this unit will provide all the cooling your TC could ever need, no matter what you do in the future to increase its power! It not only increases overall power, it also improves throttle response due to reduced inlet restriction. While its overall core volume is over 150% that of stock, it still nestles cleanly into the space occupied by the stock intercooler. Its bar-and-plate construction considerably improves both heat storage and rejection compared to the stock tube/fin design. Compatible with both stock and Hahn RaceCraft intercooler piping, as well as with Hahn/BSR PPC Tuner.

DYNO RESULTS: intercooler performance

In this dyno graph, a pair of runs from 1st through 4th gear are illustrated with the stock intercooler and piping. A strong fan blast was provided to the intercooler in both tests. Note that the power falls off noticeably in the 2nd run, which was performed back-to-back with the first. Heat soak in the stock intercooler significantly affected power on Run 2, starting midway through 2nd gear...with a total loss of over 40 HP at the top of 3rd gear! The scan data below helps show why this terrible power loss was so evident...

This data graph shows engine information during the dyno run. Study the IAT (intake air temp) data in the fourth section down. Note that where the vertical white cursor is placed, that the numbers for IAT (as shown in the left column) are significantly different for IAT (which is incoming air temperature) and IAT2 (which is the temperature after the intercooler, same was what's being delivered to the engine). You can see IAT2 elevate throughout the dyno run, reaching an ultimate total of 154 degrees...over 70 more degrees than IAT incoming air temperature! Savvy observers will also note that the ignition timing is down to 6 degrees at this point, since the PCM is retarding timing to compensate for the high inlet air temperature (IAT2).

Now, for these dynoruns, the Hahn RaceCraft Performance Intercooler and piping were installed. You can immediately see that there is no difference in power on these two back-to-back runs, quite unlike the stock equipment. The scan data below shows why...

It's immediately evident that the IAT data is now much more favorable with the Hahn Performance Intercooler. Note how, unlike the stock intercooler, the two IAT lines now track much closer to each other during the test; instead of a disturbing 60+ degree increase in air temperature like stock, we see a mere 8 degrees. Ignition timing is a more effective 9 degrees. This is a much happier (and longer-lived!) engine now!

And finally, here's where we see the difference between the Hahn Performance Intercooler and stock, after two dynoruns each...as much as 60 more horsepower, with an average of 20-30 HP increase. This translates to a difference you will feel, and a reduction in temperature your engine will thank you for.

And, a bonus...as this intercooler can support up to 700 HP without breathing hard, you will also be well-prepared for any future performance modifications you make. More airflow from more power that would just further tax the stock intercooler!
