Am considering a RMS or ESS SC on a Z3 2.3. How do they compare to a roots type SC? Which system is the most sound? Bypass,linear, etc.
Anybody done a study on this?

heat than the centrifugal. Roots brings full boost quicker and is more streeable for power than the centrifugal. Centrifugal requires rpms to bring it to full boost and is more adaptable to tight engine compartments.

It really depends on what is available for your car. You can visit the Corky Bell website, I think or something that mentions the differences.

The improvement is phenomenal. Boost lag is really not a factor. The software mapping seems to take better advantage of the gear ratios and tranny shift points.

The centrifugal vortech is the most cost effective match for the tight quarters we have in these cars. American iron has more space under the hoods, sometimes.

The intercooler would the icing on the icing!
