I have a 2005 SRT4 as my weekend car.
In stock form, it's a low 14, high 13 second car, depending on the driver. I don't consider myself a great driver, but I have raced my buddy's wrx and a awd dsm from a dig. Both got me by ~2 cars off the line, but I pulled them both in by the end of 2nd gear. That was only with a $80 wastegate at 15psi.
With ~$1000 worth of mods and a good driver, they are easily low 13, high 12 second cars...The best I've done on street tires with a few mods was 13.9 @ 107.
Trust me, all srt4 owners know their car is a neon. I know my car is a cheap dodge, honestly, the car is crap. However, the motor kicks ass and responds amazingly well to mods.
Ask his what his mods are, or just race him and see what happens...careful tho, you might be surprised....
