Default SVO 30# injectors

How much HP will these support with a stock fuel pump from a 99 F bod?

I don't know about the fuel pump, but the injectors can handle the following approximate horsepower:

May seem like an obvious answer but I must ask this is a crank HP figure rating at 80% Duty correct?

What do you mean? Keep in mind these are rated at 3 bar.

I have these on mine, I've heard they are good for 480ish rear wheel hp on an ls1 from what my tuner told me. My numbers are in the sig.

Im still running stock pump but will be upgrading soon as well as fast fuel rails.

What I meant was the chart you posted shows a peak hp of 482 I assume this is the most hp the injectors will support at 80% ducty cycle (that figure also in that chart).

RWHP on my setup can be very deceptive as my driveline losses are a good bit more than a 6 speed or even a regular A4 setup for that matter. Thats why I would think crank figures are more reliable in this situation. I have SVO 30#'s in the car now and oddly enough I never logged IDC's and I am swapping over to an LS2 shortblock that I expect to see around 25RWHP gain from. I figure I am making 480- 500 crank now so I would look for supporting in the 550 area to be safe and it is looking like I may need to step up to the greens.

Sorry, didn't understand. You are correct, 480 HP is the approximate number to maintain 80%.

You should step up to some Bosch Design III's in a 36 or 42 lb/hr @ 3 bar. Check with FICINJECTORS, sponsor, they have great prices on these.
