According to the oct. issue of 5.0&SF, they say this for the 03' stock cobra:
Bassani X-pipe - 25-35 RWHP
Long-tube headers - 20RWHP
Replacing Eaton pulley with Lightning (from 8 to 12psi) - 60 RWHP
One place offering a package, the headers, a new pulley, and a custom chip claims 500+ RWHP.
The final, properly breaking in the Beast adds (somehow) 10-20 RWHP.
These stats are from an article (p. 187-188). Sounds like there are quite a few hidden ponies in this Beast.
