how many pounds of boost can i run on a stock b20?

 

6-10 safely, if tuned right i would say.

 

What sized turbo? The better question is to ask how much power your B20 can handle. The limit of an engine is not how much boost it can take, but rather how much power it can make.

I'd say somewhere around 280-320whp if it was tuned very carefully/nicely.

Saying that you will boost 10psi on a T28 turbo is nothing when you compare boosting 10psi on a T3T04. The latter flows much more CFM, and will create a lot more power at the same pressure level.

 

thanks. It's suppose to get dyno tunned next friday

 

Im running 15lbs on t3/t4 57 trim 63.ar (680cfm) tuned myself on turboedit without any issues at the moment...
