CSF Porsche 911 Turbo/Turbo S (.1 &.2) (991 Series) Twin Intercooler Set

CSF Cooling is proud to announce the official public release of its Porsche 991 Turbo & Turbo S high performance intercoolers for both 991.1 & 991.2 models. Since the intercoolers made their official world debut at the 2017 SEMA show, a unique sales decision was made to only release these intercoolers (for a period of 1 year) to a select group of the worlds most highly regarded Porsche motorsport ECU tuners and vehicle builders. Over the past year, CSFs Porsche 991 Turbo intercoolers have been race-tested, logged, and fully validated by some of the worlds best Porsche tuners. These intercoolers have been regarded as the Go-To option for the best performance and value available in the performance aftermarket.

CSFs #8112 Intercoolers installed on theTop Speed Motorsports 991.1 Turbo S which currently holds the ½ mile racing top speed world-record @ 201.97 mph trap speed.

CSF called on world-renown and long-time R&D partner GMG Racing to dyno test the new 991 Turbo CSF Intercoolers against the OEM intercoolers for continued development & initial release.

Dyno Testing

Validation of CSFs Porsche 991 Turbo Intercoolers started with a GMG Racing modified vehicle with typical bolt-on modifications and a stage-1 tune from GIAC. Extensive dyno testing was completed over a 4-day period with similar ambient air temperatures in a controlled dyno cell and were conducted at similar times in the day (Early morning and afternoon to control air density variability). These tests consisted of several real-world test simulations with data proving a massive increase in performance and heat rejection of the CSF Porsche 991 Turbo Intercoolers.

4th gear dyno pull at wide open throttle (WOT) resulted in:

" Intake air temperatures (IATs) delta of the CSF intercoolers were ~20°F lower than the IAT of the OEM Porsche intercoolers

" CSF IATs at end of 4th gear pull ~97°F (~36°C)

" OEM IATs at end of 4th gear pull ~118°F (~48°C)

3-minute heat-soak test resulted in:

" Data logs proving that the CSF Porsche 991 Turbo intercoolers keep IATs consistently 25 40°F degrees less than the OEM Porsche intercoolers.

" IATs of the CSF Porsche 991 Turbo intercoolers start at ~98°F (~37°C). For the first ~30 seconds, IATs are actually reduced by ~10°F before increasing to no more than ~15°F before again reducing to a steady and consistent ~103°F (~39°C)for the remainder of the test (only 5°F delta from start). 

" IATs of the OEM Porsche intercooler start at ~105°F (~40.5°C). Immediately IATs start to increase, and after only ~30 seconds, IATs have already increased by 20°F. IATs increase towards a 30°F delta when the technician decides to abort the OEM testing at only ~75 seconds into the test due to high IATs reaching levels of decreased vehicle performance.

Dyno Testing Analysis:

CSFs wind-tunnel optimized 4.5 inch (115mm) width bar/plate core, is a significant improvement over the OEM designed 3.14 inch (80mm) tube/fin core. Furthermore, CSFs exclusive thermal dispersion heat transfer coating is able to reject heat ~35% more efficiently than the raw/uncoated aluminum core of the OEM intercooler. The coating is applied in California, USA by an aerospace coating company who also supplies coatings for Boeing. This unique coating is a key feature to achieving world-record performance, exclusively available from CSF.

After installing the CSF Porsche 991 Turbointercoolers and quickly adjusting the stage 1 tune, a 35whp gain was achieved by GMG Racing.
