ok this might really be a dumb question but i was just wondering how a new or bigger turbo makes more power?? the ams kit says it spools at the same time and has 20 pounds of boost same at factory so i dont quite understand how it works,,,
thanks guys....

 

more air=more power...

 

A larger turbo flows more air and is more efficient compared to a smaller turbo at the same psi.

 

It doesn't have to work as hard

 

if i buy a 4000 dollar turbo kit i will still need a bigger intercooler and fuel pump and injectors???? because more air means more fuel ? and how do you figure out how big of injectors to get?

 

Its a matter of how many PSI your going to run and what kind of fuel.

When you decide on the turbo kit just ask a tuner for a recommendation on the injectors. The fuel pump probably is good for quite a bit of horsepower but since its so cheap its a common safety net.

Most "stock" like setups will be fine with 680cc injectors even up to race fuel and high psi. However once your crawl into the range of top end turbos you need to bump up the injectors. There seems to be a lot of personal preference as to what a good duty cycle is for an injector so i leave it up to you and your tuner to decide.

 

I have called up both ams and br with questions and they were happy to answer them. If you are usnure ask the pros.

 

bigger turbo takes in more air which equals more power to the car but yea your going to new a new fuel pump injectors and a bigger intercooler. id recommend a GT35R for your turbo to
