Searched in multiple sections but can't come up with anything... What size external gate and what kind would you recommend for running a single S475 on the truck in my sig? I have a new steed T4 manifold and the S475 with billet wheel and race cover from Tmoneydiesel and got a plug for the port for now but wanted to know what size gate would keep things in check of need be. I'm going to get a drive pressure gauge in first anyway to see if it will be needed but wanted to know in advance.

Single 75 what? Turbine? A/R ? There is no right answer. a smaller 35-50mm gate should help. I would go at least 50 if you plan on spraying it.
 
It will probably never get nitrous but maybe more fuel eventually. I can always go too big correct? It will just be harder to "tune"

I wouldn't go more than 50mm. Should be overfueled with the injectors/pump setup you got now.
