worth noting that the rotrex unit is a centrifugal supercharger (effectively it's a mechanically driven turbo), so available boost will be related to engine speed, whereas the positive displacement superchargers like the eaton types should in theory provide the same boost at all engine speeds


I don't think so otherwise the BOV will be open on anything over tick over

why is that ?  i thought positive displacement supercharger setups didn't really need bov/dump valves..

I am seriously considering supercharging. I love the torque profile. The vmax seems.OK. again the specialist components rotrex conversion shows very impressive gains but only really on the mpi rather than carb. Again. Where are the reviews from specialist components customers
Currently I think the mg metro box is a 3.2 it seems pretty good . 4th is slightly tall but some it seems to be a happy medium.

 

if its an original mg metro box then it should have a 3.44:1 final drive. other metros had other final drives, but I am pretty sure all Mg Metro's (except turbos) had a 3.44:1 from new
