Default Stock fuel rail and lines.

What would you guys say the max whp you can make on the stock lines and rail? I'm asking because I just dynoed my car and it made 621whp and 680TQ. I want to turn the boost up a few lbs but I wasn't sure if my rails and lines could handle it.

I'd say that you're pushing the limits of the stock lines and rails..I'd honestly upgrade soon...

rails will be fine...but your car is making 600+ lines should be changed to a -6 or better. we have a 985 hp (to the wheels)c5 zo6 on stock stock stuff (exp fuel pumps, 044s) for the past 2 years and have had no problems.....save a much money as you can don't wast any...

I always heard that the stock fuel pump should be upgraded with anything over 400rwhp.
