Default Size WG and BOV

How do you know what size BOV and Waste gate to run? Different size for amount of hp you want to run? Looking to push 1000rwhp or really close to it

I have twin tial 44m gates and they worked fine for all boost levels I've tried, and a single 50mm bov but I've heard of people running two before when they are running a lot of boost

GT47-88 right? I would go no less than a Tial 44mm WG and start with one 50mm BOV.

You an get a JGS 50mm wastegate for ~$379 ... about the same price as a 44mm Tial.

Waste gate size is going to be dependant on turbo and motor size AND how much boost you want to run. If you want to run a lot of boost you won't need a very large waist gate, but for low boost a larger WG will be required to be able to bypass enough exhaust gas to regulate boost.

They are nice as well. We carry them on the shelf. The 50's are the best bang for the buck.
