my current set up is a t3 with a a/r of .42 intake and .48 on exhaust,its not holding boost,not big enough,i have a to4e comp housing,backplate and blade,so in theory,i could just put these parts on my turbo and have it balanced,then i have a t3/t4,the to4e is freakin huge though,.70 a/r,so what could i expect from a t3/t4 with a/r #'s like .70 intake and .48 exhaust,i dont know the trim of the blade,if there is a way i could find that out i would appreciate you leting me know how,if there is some how some way of calculating what i would end up with,please tell me how,i was thinking the .48 exhaust would make it spool fast,but would it spool too fast?help please.im only wanting between 7-10 psi depending on what you think this new set up would do to my stock internals,im using a vafc,370's and a btm so detonation should not be too much of a problem.thanx.
