max psi on bottomend?
What psi can you safely run, and occasionally play with on a stock SR with basic bolt ons (e/i)...I am installnig a BC and am wondering what would be a safe setting boost wise for playin? something to be safe and conservative, but not too granny?

Boost doesn't really have that much meaning.....what really matters is total airflow.....
For example, on a T25, the turbo is inefficient after ~14 psi or so...and will probably fail eventually. However, with a larger turbo, you get the same airflow to the engine (and thus horsepower output) with less boost.
For the T25, I would say keep it below 14-15 psi if you want it to last.
Also, bottom end is typically good for up to ~400 hp or so....
Someone please correct me if I am wrong
