does a t4 .58 ar flow more then a t3 .58 would?

[compression]

well as exactly as the title states, i understand the housings are the same size(ish) but the inlet on the turbine housing is a little larger on the t4 then the t3 , so would the t4 flow alittle more? reason being i have a choice between 2 turbine housings only , .58 t4 or a 1.13 t4 and i want around 600-700 whp i believe the .58 will be too small, but the 1.13 will be too big, i BELIEVE. im not sure. so input is always welcome.

Yes, a t4 .58 will be larger than a t3 .58.

While the ratio between the area and the radius of both housings are the same, the actual area and radius of the T4 is larger than that of the T3, so the T4 is larger.
