The superchargers boost is dependent on the size of the pulley on it's snout/shaft. 14-71 big block/Alcohol and Top Fuel superchargers typically run in the neighbor hood of 40PSI, Vortech superchargers/centrifugal units can make as much boost as you want, there are all different shapes and sizes of compressors just like turbos! Unlimited boost potential depending on the size of the unit and the pulley that spins it. Smaller pulley=More boost!

someone is smoking crack if they think that those rotors are 2200. i have some for my drag car and didnt pay that for them

 

Man.. I don't want to be rude.. but sometimes thread like this makes me wonder if people know anything about Fd or what kind of rotary engine its has.

LIke you said before do some search to find out how things work and start making your own decisions.

Supercharger is pointless on FD's.. Search and see how it works.

 

In the new issue of RX Tuner they have an interview with RE Amemyia in which he stated they are working on taking the lower compression FD rotors, and putting them into a 3-rotor configuration Renesis. Might turn out pretty intersting.
