So I came in here because I was actually curious to see how one would go about building their own supercharger dealy-bob (reminiscent of the turboclunker for me

). I have some sympathy for the OP and enthusiasm for his project, if it's what he wants to do. Obviously he's a bit of a know it all, which combined with a lack of information, has made him put his foot in his mouth several times. I would ask everyone to cut back on hazing him, but I know that's hard to do with an argumentitive personality. But this is MUD, not pirate, so let's see what this guy's plan looks like.
A few points (that others have already made):
1) turbo or supercharger, neither has anything to do with your front bumper or winch. An intercooler is not necessary, and if it's necessary
for you, it can be placed in other locations than the front bumper. I did it. Neither the existing Wits' End turbo kit or the TRD supercharger (which I assume you plan to mimic) require you to do anything at all behind the bumper. There is also likely a meth injection system on the horizon, which will be easy to accomodate and be a reasonable substitute for an intercooler if you wish.
2) Wits' End turbo kit is in the final stages of CARB approval. It is out on the road across the country.
3) Forgive me, I'm not a California resident, but I believe If you're building your supercharger system from scratch it will have to visually resemble the TRD supercharger pretty closely in order to pass for one with an emissions referee. You'll need to get that sticker from Joey. Just because there is
a supercharger that is CARB approved doesn't mean every/any supercharger is approved. The thing is approved as a whole system. Just as you can't pluck a Holset turbo off a powerstroke (which is CARB approved) and build your own system around it and still have it pass emissions.
Just trying to help.

Good luck!
