What turbine housing size, 70mm turbo

[fatt6903]

Im having an old school bw370 rebuilt. I got it from another racer that made 730whp@30psi on his b18c. It had a t3 .70ar housing on it. The wheel specs are 70.1mm in- 101.9 ex for the comp side and 80mm in- 71mm ex on the turbine. Has a billet wheel and is undergoing a lighting process. The turbine is also going to be clipped 10*.
I will rev to 9k, kelford 280s, 8.1cr, jmf drag. I plan to run upwards of 40psi. E85 with custom 2400cc injectors. My options are .80,.90 and 1.00 all in a full vband housing. I am thinking the .90, from what ive herd the vband in/out housings flow better.

Any thoughts??

Are you going t3 or t4? Divided or none divided? If you are interested in a T4 i sent you a pm. Why are you clipping the turbine wheel?

My turbo builder is telling me its for the best. He says that the .90 is the way I should go but I want to here what other dsm'rs are doing. Im going with the Vband inlet and Vband outlet stainless housing. I know that guys in the sfwd class that I race in go with the 1.10 tangental housings and bigger but there revving 10k+
