Having a debate with my friend...

Take 8 PSI on a 16G, and 8 PSI on a 20G - Pretend you can duplicate the car in every way and form minus the turbo sizes - is 8 PSI on a 20G better than on a 16G and will it make more power?

Will 10 PSI on a 20G kill 15PSI on a 16G??

Basically I'm trying to say, do bigger turbos always make more power at lower boost levels and at the same boost levels as smaller turbos, and my other question to you is WHY?

 

if you push the same number of psi on both turbo, the larger one will always make pump out more air--which means more power.

 

I'm sure 100 people will respond to this as it's been beat to death, but my take on it is that you could have say a little rubber hose and 3" pvc pipe. Put 8psi to each of those. It's pretty obvious which is going to flow more for the same psi.

 

think of a water hose, both set at the same presure but one is a lawn hose and one is a first hose, which would fill a 500 gallon pool the quickest.
