rotrex supercharger

[sdmf]

well sure its a lil pricey but superchargers have power on demand with no lag. how many horses do you want on a yaris anyway, i was only hoping to get to the 200 mark, which would totally be possible with the rotrex, it acts like a turbo but less maintainance and no cooling issues. unlike the turbo. i also noticed s/c last longer than turbos. its about the same price as the zpi kit. i should start saving then we can have s/c vs. turbo showdown. hehehehe

Thats not entirely true. A rotrex is a centrifugal supercharger, meaning it is nearly identical in functionality and design to a turbo coldside. It is just mechanically driven as opposed to exhaust driven. Only positive displacement blowers (roots, and twin screw types, Blitz is a roots type) offer instant full boost with no lag. Centrifugals still need to "spool up" a bit before they hit full boost.

As far as maintenence and heat, they are all close to the same. The turbo hotside will add a little extra heat, but it is more efficient than a supercharger.

Nice product


wonder how much you can play with the pulley to boost up power...

but still i would rather stick with a sc12 for a small engine like the 1nzfe
