If I were to make an exhaust header for a 12a turbo, would I have to use both exhaust ports to have the turbo build up enough psi? I wanted to just use one, but didn't know if that would be enough. I didn't know how most of them were.

Thanks for the help.

 

you don't want to use just one, it will make the turbo take longer to spool because its only getting half of the exaust flow/energy. In this case, you should merge both into the turbine inlet. Just curious, why did you want to use only one?

 

you cant do that, it wont work and by doing that your making one rotor work more that the other and is gonna cost you a engine. you need to use both not one
