Well if I was only expecting 470whp I wouldn't have spent $2k on turbos as that would only be a 30whp difference for me. I'm pretty confident I'll have no issues hitting 500whp and doing it without pushing the little turbos past their limit. I guess it's all speculation for now though till I put them on.
