Supercharger and thermostats
For those running a supercharger, or more specifically a Whipple, are you running the factory thermostat or did you install a lower temp thermostat? Here in central Texas a majority of the summer is triple digit weather and I was thinking about installing a thermostat that was 20 degrees lower. Just curious to hear what the rear of y’all in the club are running. |
I’m running the lower temp one Whipple sent with the kit. The 18’s didn’t get one? My temps hover around 185 give or take a couple and it’ll move into the low 190’s on a hard run or extended 90+ mph driving. That’s what the dash shows with the actual temps enabled with Forscan anyway. |

I use the Reische performance thermostat 170 Degree in both my truck and Edge sport. |
The 170 isnt needed in the 2018, and it will lower your fuel economy.
The factory t-stat is a 180 fyi |
Why would lower temp T-stat decrease mileage?

Engines are generally more efficient the warmer they are, to an extent of course. He might also be referring to an open/closed loop issue if the engine doesn't get warm enough.
I personally like my engines to be between 195-200, and my factory t-stat is not cutting it despite an aggressive fan profile and a large vent cut in my hood (supercharged truck). So I bought a reische t-stat a couple days ago and will be installing soon. |
That makes sense. Please update the thread with your results.

Dustin Whipple claims 20 engine horse power can be gained on the 2018+ f150 and mustangs by replacing the thermostat. Says the reason the whipple kits don’t ship with them is due to CARB compliance. |
