    • Switzer gets over 600 horsepower at the wheels out of a 2017 Ford F150 Raptor 3.5 Ecoboost on 93 octane pump gas

      This is absolutely crazy power out of an off-road truck. We are talking 250 horsepower at all four wheel over stock. It is even more amazing when you factor in that Switzer achieved this on 93 octane pump gas.


      Switzer says they are happy with the curve and where they are at for their Raptor Ecoboost package so they will not be pushing further.


      Obviously higher boost or E85 can come into play but Switzer wants a reliable pump gas package.

      With a lot of experimentation and software improvements I was able to get our 2017 Raptor kit dialed in more appropriately. Very happy. Now we need a little more fuel and I want to look at reducing our exhaust back pressure as all of these curves have been done using the stock exhaust to keep the truck sounding good and not droning during cruise.
      That curve comes with a spool sacrifice until 3500 rpm but the top end pull is night and day.

      Will this low end sacrifice hurt offroading performance or is this a package more appropriate for street use? The stock Raptor Ecoboost runs 14.1 @ 96 in the 1/4 mile. This Switzer version should be well into the 12's.

      Kind of makes you wish for a new F150 Lightning, doesn't it?
