Ok, seriously...

Im not saying that there arent some incredibly durrable and efficient turbo's out there that can be used for offroad, but i am saying that for the price the general consumer is going to get better end results from a supercharger. |
What makes you say that?
Look at Dakar and just about any Rally Series. Almost ALL turbo charged. That requires WAY more durability then anything most of us need. They hit water and snow like crazy! No belts or tensioner to fail, better intercooling ability and less stress on motor because of no draw from the belt driven compressor.

That's why we regear. What rock crawler doesn't gear WAY down anyway? With dual cases you could run a rotary motor in a rock crawler and do fine. Hey, that would be kinda cool....  Turbo's also don't need any extra engineering to do that, they just need to be properly sized. Yes, a lot of honda kids go out and buy turbos that "support" 600hp and put them on their 1.8 litre motor and they don't see any boost until 6000rpm. However its really not that hard to find a turbo that will be sized correctly for your motor so that you receive benefit from your turbo at very low RPM's, under load - when you need it. The engineering has been done, it just requires a little research.
How many factory supercharged vehicles are there? How many factory turbo charged vehicles are there? That should tell you something...
Here's something else, Turbocharged motors will produce less stress on drive train. A lot of what kills drive train is shock load, i.e. when the slack is taken up in the drive train from dropping the clutch fast. With turbocharged motors the power 'builds' as the turbo spools which doesn't put as hard of an immediate load on the drive train. It's the same logic as why an ARB will help save your CV joints.
I suggest you try both for yourself and decide what you prefer..
