I have a ls2 with 317 heads with a tc78 right now and i want to go bigger. Now soon forcedinductions will offer a better tc78 with bigger exhaust wheel but that will be the price of a whole new unit. I kinda like the fabrication part of things so hell i was almost thinking if the exhaust side wasnt too big i would just pick up a tc78 off someone thats upgrading soon and just build a twin kit.


OK so what would happen with twin tc78 1.15ar on a 68mm wheel?


I have a 236 232 .60x .61x 115 cam and ported heads.

Would be fairly laggy setup with those cubic inches.

Waaaaay laggy. We (LS2Formula) had twin TC78's on a 422 with .80 A/R housings and that came up nice. Car ran 7.8 @ 180 mph on that setup.

Swap the housing's out for something smaller than los' buddy used on his 422. Then I can see them spooling well for that size motor.
