Do you plan on off-roading? The complexities of adding an after-market twin turbo kit to a Raptor is pretty intense and not necessarily a good thing. Whipple has been done quite a few times and has a pretty good track record. Then again, if you don't plan to off-road, then go for the twin turbo.
There are plenty of offroad recreation vehicles that use turbochargers for big power. Any additional complexity can be troublesome, but you don't have innovation or improvement without giving it a try. Even the superchargers had to be proofed in order for people to trust them. I believe we have the same situation here. The idea is already proofed in other offroad vehicles and just needs to be transitioned to our platform. As for turbos themselves, I've had a couple turbo platforms and they were both extremely reliable. A couple PROs to inspire innovation, the turbo is that it is more efficient than a supercharger, you can improve mileage, there is no parasitic loss due to being belt driven, or a belt to break or slip for that matter (my old SC belt would slip from time to time). All of that said, I'm sure it could take a shit on you just as easily as anything else. I'm giving it serious consideration, i'm deployed right now, i'll report back if i go that route.
