G8 GXP stock fuel pump and clutch limits I have a 09 GXP , I'm going to be doing cam , headers and some port work soon . Will factory fuel pump keep up with this . Also how about stock clutch ? I'm just doing a mild cam , something around mid 230 duration , nothing extreme . Also not a track car , it will never see drag radials or hard launches . Any insight would be great . I would guess RWHP to be around 475 at most .

Stock fuel pump and injectors will support a cam and bolt ons just fine. Ive got a GT with cam and supporting mods, plus a 100 shot and the stock pump is supporting it currently. Though I do plan on upgrading before I go any larger on the kit because I’m pushing it now. It all depends on the car but a lot of guys run stock pump and injectors up to 500rwhp NA a lot. As for the clutch, if you’re on street tires then it will last a lot longer, especially not seeing a drag strip. You should be ok for awhile depending on how you drive.
