Well, im not sure if it requires the same supports as a turbo setup, but I have a 255 walhboro fuel pump, and a vortech fmu with a 12:1 disk, and my car has no troubles running daily at 10psi...but this is turbo, so I dont know if it applys to you or not. Everything else is stock about the car, except a 2.75' exhaust, and a "test pipe"...but besides that..all stock, oh you might also wanna look into getting a clutch...just a thought...it will slip with 8psi daily.
