how far can you take a 38mm wastegate, safely???
a friend is starting on his 2.0L turbo...and i'm helping him find parts...
what would you run for 500whp, wastegate wise? is the 38mm tial safe at that level, or shoudl he upgrade to something else???

Re: (GSRswapandslow.)
You don't want to run more than double the value of the wastegate spring, so you can't determine that until he decides how much boost he will run.
As far as wastegate sizing, directly from Tial's website: "Contrary to popular belief, larger higher HP applications do not necessarily require the largest wastegate available. The lower the boost pressure you are gunning for the larger your wastegate needs to be. An engine/turbo combination that is set to 25+psi has a smaller wastegate flow requirement than the same application set to 7 psi. This is because the wastegate is used to lower the boost not raise it, the lower the boost pressure is set the more flow the wastegate must allow."

Pretty much the same here. 38mm wastegate / 1 bar spring / 23 psi.
