ok, i am getting ready to pull the trigger on a power adder, i have been planning on twin turbo's, but just rode in a friend's 05 mustang gt with a kenne bell 2.6. - - - very nice. he has stock internals. hasn't totally diswayed me from twins, but it has gotten the brain juice flowing again. next month i take delivery of a forged/built 4.6 teksid block, stroked to 300 c.i. it has stage III MMR heads, and (for now) stage II MMR turbo cams. most of the rest of my car$ has gone into suspension/shoes, . . . with under-drive pulley,s a C&L CAI, and SCT/VMP tune being the rest of my performance adjustments. considering my new bullet is stroked AND built, . . . what would be a reasonable estimate of the HP/torque attainable with an intercooled 2.6 twin screw? i am looking for about a 550ish hp daily driver tune, and a 750ish track/friday night tune. thanks, doc
