Like I said you can get the big hp numbers with centrifugals, but they are only at the higher rpms for the most part. Pick up some import mags and you'll see what I mean. The torque curve is diagonal, as opposed to flat. In the Civics its real bad because the motors rev so high, the supercharger has to be geared to survive at high rpm.

I'm not trying to be a *****, but I am telling you that centrifugal is not the way to go for your car. You'd probably be lucky to turn a 15.0 in the 1/4 mile - very lucky. And that is still damn slow considering my car should turn mid to high 12's and chipped 951s run mid 13's.

A recent issue (february 2001) of sport compact car has a whole mess of supercharged cars tested and compared.

The 270 wheel hp civic turned a 14.4 quarter (centrifugal)

The 180 wheel hp neon turned a 14.7 (roots type blower - just like rimmer).

If you look at the torque curves you'll see why the neon is almost as fast with a lot less hp.

They even had a Jetta VR6 with ALL the tricks including a centrifugal blower which ran only 15.0 in the quarter.

A Toyota Solaro with a roots type blower was also tested and put out 243 to the wheels and turned a 14.5 - just about the same as the civic, but with an auto, probably 500 more pounds, and with 30 less hp. If you look at the torque curve you'll know why.

You know why centrifugals are so popular now? Because hp sells! Why else do we spend so much on MAF's, turbos, exhausts? The only problem is the HP from a centrifugal is very decieving - It's only achieved at very high rpms.

Anyway, good luck with your search.
