While I do agree with Demon, one thing that needs not be forgotten is that we're comparing stock to modified. These SRT-4 guys really have it going for them as any factory F/I car has a world of simple modifications that can yeild major improvements.
I'm a huge Duratec/CDW-27 fan, but there will come a time when our engines are no longer competetive in the hp wars that are errupting before us.
My take is that if you have a light, heavily modified 2.5/3.0 liter, know how to drive and run in with a "stock" SRT-4 then there is a chance(slim) you'll be able to put it to him/her. Modified to any of our N/A motors really isn't fair game IMO. Remember running mid-high 14's at 94-96 mph as some of us have done in the past will put you within a carlength of a stock SRT-4 with a decent driver. If you cruise SRTforums you'll see that quite a few are running mid-low 14's while quite a few are in the 13's if not better.
Good luck....don't worry about me...I've got a turbo!
