What does it matter? I don't see the correlation between off road and a supercharger.........other than:
A) You can't afford it
B) You just aren't into the extra horse power (some of us gear heads would supercharger our lawnmowers given the chance just cause). You start throwing the practicality clause around your reasoning goes out the window, if we were all practical people we would be driving entry level 1/2 tons (light half tons at that) to do what we do.
Anytime I hear the argument.........less reliable.........more to break........all I really hear is you can't afford it. I have had several aftermarket (and OEM) supercharged/turbo'd vehicles and have had ZERO issues with reliability....ZERO. And NONE of them were left as they were sold (meaner hotter tune or additional add ons)
You want to be a hardcore race car driver in the desert then build a race truck. The Raptor is (flame suit on) an F150 with a wider stance and different suspension...............that is it.....same motor, same frame (with the exception of the SCAB being shorter and beefed up shock mounts), same transmission, same differential (obvious 4.10's), same interior (cosmetics), and same transfer case. How many 6000# race trucks you see? With leather and A/C, Sat radio, Nav.
And the 1st person that says......have you ever been days from civilization with your truck is going to get their birthday taken away
