The csrt-4 is no slouch.... 400 whp on the stock turbo is doable. If the srt-6 was stock and the srt-4 was in its powerband i could see it happening... It does have sufficient mods to trap 110ish so its possible. If they indeed went up to 120+ mph then its not out the question. Most people exaggerate when telling stories. I had similar mods on my neon plus meth and tune and there is no question that my neon would have put a hurting on my basically stock srt-6. Now off the line its a whole different ball game.
