Great replies guys
OP Should probably post in Newbie section...

What I believe the OP is referring to is possibly; What is the advantage of running a bigger wastegate, say 50mm with a smaller exhaust housing on the turbo...

 

lord i hope thats the case. the wastegate isnt gonna have much intake draw or exhaust flow. haha.

 

i know what the heck a wastegate does but why not run a slightly smaller turbo and close the wastegate more and wont the turbo spool quicker if its smaller

 

I see a'sploded evos in your future...

The waste gate is the gate that lets out waste air. And yeah a turbo will spool faster if smaller, but make less boost.

 

and wont be efficient at anything over 5psi

 

Basically what your asking is, "Why not turn up the boost on a smaller turbo"

You can only do this to a certain point before the turbo is out of its "efficiency". This is the point where the turbo is blowing hot air and the intake temps will rise. Many people combat this by adding meth injection which will allow you to use a smaller turbo, turn up the boost, push it past its efficiency, reduce knock, and cool intake temps. But there is a certain point where the turbo will reach a limit for flowing enough CFM for the amount of power you want to make.

 

the winner of the year is........

 

hahahah
