Porsche 911 Turbo / Turbo S (991.1 / 991.2 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 world’s most highly regarded Porsche motorsport ECU tuners and vehicle builders. Over the past year, CSF’s Porsche 991 Turbo intercoolers have been race-tested, logged, and fully validated by some of the world’s best Porsche tuners. These intercoolers have been regarded as the “Go-To” option for the best performance and value available in the performance aftermarket.
Validation of CSF’s Porsche 991 Turbo Intercoolers started with a GMG Racing modified vehicle with typical bolt-on modifications and a stage-1 tune. 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 (IAT’s) delta of the CSF intercoolers were ~20°F lower than the IAT of the OEM Porsche intercoolers.
• CSF IAT’s at end of 4th gear pull ~97°F (~36°C).
• OEM IAT’s at end of 4th gear pull ~118°F (~48°C).
