Should try something with a billet 71mm comp wheel with the 58mm hot side on a dual ball bearing cartridge. Near identical spool with capability to hit higher than 450whp on e85. Do IT.
Very nice build. Will this be a straight line car? 650whp in an awd is a bit much. And is there any specs on the cams you used? I feel like with the x3576r i need like a 272/272 or a hair smaller and rev it out to 7800rpms to make use of the turbo fully. Especially if you wanna hit 650whp mark. Thats around like the 34 to 35 psi boost mark. Hopefully the valve train will be up to snuff. Again Good Luck! Also dont forget about maybe getting larger injectors than 1700s. With my double pumper in a surge tank to my 1700s i also get a little nervous about leaning out on e85.
You cannot get it at the pumps here. But you can buy E100 in barrels.
