SpecterGT260

just wondering what the dyno proven rwhp is of a stock 03-04. we hear alot of BS around here about how much underrated they are. i know they are some, and they have to make better than 390 to hit the mid 12s with IRS like they do. anyone got a sheet for a bone stock cobra?

They make between 360-380rwhp. I tihnk theres already a thread about this just do a search.

from Wikipedia ................

Debuting in early 2002, the 2003 Cobra came with a supercharged 4.6 L DOHC engine rated at 390hp (291kW) and 390ft·lbf (529N·m) of torque. It was later learned that SVT (Special Vehicle Team) had underrated the Cobra, as many owners have reported 430hp (321kW) and 430ft·lbf (583N·m) of torque.


430hp would make about 360rwhp.

cool, i figured about 420, so i wasnt too far off

420-430hp is also what Saleen advertises as horse power on their
new S281 w/ SC.
Basically same thing as 04 Cobra

but the newsaleen is a 3v isnt it?

Thats why I said "Basically"

They didnt really make a whole lot more with this new engine design
