Snails the size of your head: SEMA's wildest turbochargers and superchargers

I don't know what's going on here with all the copper-like piping, but man, that turbocharger is the size of my head.

If one massive turbocharger won't cut it, why not opt for two perfectly placed but slightly smaller snails?

This BMW E46 M3 must be putting out some ridiculous power. All that gold wrap helps keep the heat from melting other components.

You know you're onto something when your turbocharger is roughly the size of your cylinder head. (This is on a late-1990s Civic hatchback.)

Turbos aren't just for cars -- they're for boats, too!

It ain't a SEMA diesel without a big ol' snail strapped to it.

Long exhaust pipes? Who needs 'em?!

Again, here's another turbocharger nearly the size of the cylinder head.

This impeller is HUGE. How huge? Keep scrolling...

That's a normal turbocharger next to this billet impeller. What does this power, a battleship?!

How much boost is too much boost? Keep on scrollin' to see even more ridiculous turbochargers and superchargers.
