I'm pretty sure the compressor size affects the spool up and top end, but how exactly does the exhaust side's size matter? Thanks I know its a newb question I've just been wondering for a while....

 

You can't make generalizations like that.&nbsp A turbocharger is a complex mechanical device that needs to be custom tailored for each specific application.&nbsp You can't just slap parts together and slap it on the engine and expect it to work.

As a rule, compressor size give you potential peak power.&nbsp Turbine wheel and housing A/R dictate power band (moreso the A/R).&nbsp Turbine wheel trims dictate the "efficiency" of the turbo, and has a little to do with "lag" due to turbine wheel mass.

You might want to read Hugh MacInnes' "Turbocharging" (a bit dated) and/or Corky Bell's "Maximum Boost" books for esoteric information on turbos and their terms.
