seeing that he
JCW mod for the S involves a replacement cylinder head, does anyone know just what he is doing that requires this head
mod?
i assume that he takes your old head as re-workable core, but then:
if his kit has higher boost pressure, does he
mod the combustion chamber to :
correspondingly reduce the compression ratio?
different flame propagation shape?
plug layout?, twin plugs?
what about cams?
is the valve train modded for higher rpms, and does he get HP that way?
in a supercharged engine, one would think porting and valve size would be less important and flame blowout and propagation would get more important?
anyone know about this?
