How fast with a 76mm turbo?

[Overkill]

I run twin Tnetics 76s in a 383. Just curious why you are using a single 76 as the starting point to build or change your engine combo? I would go with an 88 or bigger and use as much as you can with your current motor. Call Matt at Supernatural, Jose at Forced Inductions or Robert on here sells some bad *ss turbos for a great price.

Dam s475 single too small for a 380!?
I got a friend that runs 6.3@108 in a 7000lb truck with n20 on a 403
