This is why you MUST upgrade your 911 Turbo S Intercoolers!

Contact CSF on IG @:csf_radiators I took the below precautions to ensure the highest level of IC comparison accuracy I can get without getting involved with equipment instrumentation. 1. Leading to the WOT pulls - the vehicle idle time, driving route, driving manner, and the HVAC settings were all the same. 2. The stretch of road which I did all the runs on was the same. 3. The ambient temps and DA were very very similar on test days. 4. The starting mph/RPM on all runs were the same. Hope you enjoyed the video. More to come! Please excuse my math mistake. I think 70 to 90 is 20, not 30. lol
