Hi, I've taken a good look at the 2 most popular units offered by Comptech and Vortech.

After checking out the HyperRev Mag, I noticed that 1 driver actually had a
roots-type blower rather than the 2 centrifugal chargers readily available.

My 2nd Rabbit GTI back in the day had a roots-type blower made by Autotech
and it made headache-causing torque in the lower and mid ranges. My understanding of centrifugal chargers are that it requires some time for it to provide boost which appears to come into play at higher rpms, although I don't have any personal experiences with these.

Is there a roots-type SC available for the S2000 now and if so, is the kit readily available or is it an early prototype? Any pro and con comments would also be welcomed.

 

They are sold overseas for right hand drives only, something about not enough space to install on left handed drives. Had a picture of one installed but lost it when my computer crashed, that's been over 1 1/2 years ago.
