Typical numbers based on adequate fuel volume assuming stable regulation (BSFC dependant):
600RWHP NA w/o booster (13.5V)
700RWHP NA w/booster (17V)
550RWHP FI w/o booster (13.5V)
650RWHP FI w/booster (17V)
Some customers have exceeded these numbers and some have fallen shy depending on their application. A 97/98 FMFPR system is highly recommended for all applications.

By the way, just to add, I put 572 rwhp through a turbo 400 w/non locking converter 3" steel nitrous ready driveshaft and a 12-bolt on a 100 shot with my stock pump. Tried the 150's and she went too lean and I let out, and she put 598 rwhp just before I let off. So I should hope that the racetronix i've put in there now would be good to more than 600 rwhp w/o the boost a pump if my stocker was holding just fine @ 572 rwhp! Had no inline, no nothing, just the stock pump.

At high HP levels pressure drop becomes an issue that is why a front-mount fuel pressure regulator is required to stabilize rail pressure.

Series will provide higher pressure capability while maintaining volume.
Parallel will provide much more volume but pressure is more limited.
For F99+ cars series is not recommended while maintaining the bucket's functionality.
