My comment came out all wrong.
But esentially you don't need a huge wastegate just because it's a v8.
You have to remember that a v8 is going to have a larger volume of exhaust, but it's also going to take in a larger volume of air.
Things like turbo size & engine mods & desired boost range will determine if you need a bigger wastegate to keep boost down.
For his setup the wastegate he is using should be more than fine & that is all that matters.
