Default What size wastegate nessesary for a 750 rwhp setup

Well this is the thing i cant calcualate, so maybe someone knows.

Wastegate requirements is based on turbo size and minimum boost desired..

With a T-76 sized turbo, what size wastegate is required? Im looking at the Tial 38mm and the price is decent on it, im hoping its enough to work fine considering minimum boost wanted is about 8-10 psi

What A/R and turbine housing?

What are the engine specs.

What range of boos levels do you want to run...?

I'm sure if you have a good turbine housing to engine match up and get realistic with the min boost 10-12 as opposed to 8-10... The 38mm will be fine... Sometimes you really can't run a monster turbo on the low low... Look at a comp map.. They dont like it no matter how big of a gate because they dont like the tiny pressure ratio....
