Upgrading my turbos from TC 76/68 .81ar units to the T-series HPC billet wheel ball bearing 76/75 units. I am not sure what ar to get .96 or 1.15. The motor is a 427ci dart lsnext with tfs 245s 6bolts heads.

Would like some input on the .96 ar vs. 1.15ar.

DEFYANT

I would do the .96 A/Rs. I know someone on here ran 7s with twin PT7675CEAs and .96 A/Rs.
