I was in the same boat. As far as I've seen, the fastest all motor Crossfires are in the high 13s, quarter mile wise. If that's not fast enough your only options are nitrous or an SRT6. 74mm throttle body, cold air intake from Needswings, and a tune from Eurocharged is expected to net you in the 260-270 crank HP range... OEM exhaust flows very well, no gains to be had there except sound. I'm sure someone will be along to argue the numbers or methods shortly if I'm in error
That being said - the Limited is still "quick" enough to bring a smile to your face, and if you get it on some curvy back roads you won't miss the horsepower as much as you expect. Not that it wouldn't be nice...
XME, just exactly where have you "SEEN" the fastest "ALL MOTOR" Crossfires that are in the 13's?
I've been on this forum for 9 years, and yes I've heard "talk" that certain cars with 270+ hp that are "capable" of 13 sec. times. But those very same people that make those claims, also say that they don't have to prove it to anybody. They just have faith in their very own seat-of-the-pants dyno.
Unfortunately, in this age of everything being captured on video, 1/4 mile time slips make things a "fact" and not speculation.
The only NA Crossfire to run in the 13's (that I'm aware of from this forum) does so using NOS.
The fastest 1/4 mile verified by a time slip, I believe was 14.38 or 14.40.
If anybody has spent the money to build their Crossfire into a 270, 280, or 290 hp fire breather, as far as I know they have yet to take it to the drags and verify it. Certainly, if they can afford to spend the money to build it, they should have enough to test it.
Personally, I don't think it's going to happen with the stock 3.27 gear that we have. Maybe with something like a 3.55 or 3.73 we may see it happen.IMO
More than likely, it will be a 6 spd. since they are nearly a 1/2 sec, quicker in the 1/4 mile in stock condition.
