Can you post up a timeslip... this would probably be the easiest way for the knowledgeable people to give you some insight to how you can improve the quickest...

practice is the best thing you can do....try different launch rpms, different air pressure in the tires, just to name a few things to try...

Try using the forward gears, but that is a real good time for reverse.

You get a different car. Crossfires are track cars, not drag cars. It takes 6.5 seconds to get to frikkin 60. How else do you think we can top out at 186mph (with retarded limiter removed) with only 215 horsepower or watch a Viper not be able to hit a good turn even close to as good as you going 135-140 on the freeway and watch him slide, brake and fall back in your mirror (my shining moment), how do we do that, huh? Because we sacrifice acceleration. If you wanna be bored goin in a straight line and gettin a 15 second thriil, get an American or Japaneese car and mod the hell out of it so you can only get 11 seconds on thrill. Crossfires are way too well engineered to be insulted by going in the same straight line again and again. You own a magnificent machine, use her for what she was made for and learn to track race and I promise you won't be asking "how can I improve?", you will be asking "where can i find a more challenging track?"

OK now seriously, we need to know more. what mods do you have on . CAI, Flash tuning, plugs, etc.
If you are launching a six speed there are some unique things to do, depending on how seriously you want to challenge the goal.

One problem with our clutches is the hydralics have a restrictor in the system. Keeps you from "popping' the clutch. Expensive but, you can have it drilled out or removed.
Secondly, the 19" wheels are not helping. Smaller wheels on the back would improve launch. But hurt handling.

A good cold CAI system is paramount. Go single 3.0" on an NA.

Change your shift parameters. Yes, you can do that on a manual. The rev limiter is set at 5470 RPM's. Get gears 1,2,3 set at 6300 RPM's so you can go faster sooner. With a good CAI the engine will have an enormous gain in performance low end and top end. This will maximize its use. Get a tuner like Eurocharged or TVT to do this for you.

Do what Doc suggested with tires and shift patterns. The hardest shift is not 1 to 2. It's actually 2 to 3. You lose more potential there if you miss the gate or go too soonor too late. With the Rev limiter modded to 6300 you can get to 60 in second and almost to 90 before the torque drops off(assuming stock wheels). If you are pulling into fourth under 11 seconds at more than 90 MPH you will hit 14's.

Now, practice, practice, practice.

No, you don't need a different car.

BTW, it goes without saying but get the tools and stuff out of the trunk. Run with a 1/4 full gas tank. Play heavy metal on the radio. Yanni doesn't help go fast.

I thought the rev limiter was higher like 62-6400 anyways? except if not moving? good idea about this hydraulic clutch tip. I would like to go 17' all around. Why is single better than a double CAI?

I would think a single would do just as well as a dual on the N/A...and the advantage is just $$$$$$ savings...big difference in price...

..

Nope. 5470 on the manual.

If yours is goinghigher, somebody changed them post factory.


The single CAI is more available. The double versions had a problem with turbulence but recent models from Needswings seem to have that solved, thanks to Woody's designs.
Installations look really cool too!

Doc is right, the singles are lower in cost. And installs are far more simple.
17's would give you a lower stance and some help on the accelerations. Moment arm will be lower and the wheel mass will decrease. Not sure the Trac control will like it.

Car will look like a ricer won't it?

Well with those revs as the maximum I guess we can cut the HP down as well.
From the spec sheet.

 
Power (SAE net) _______________________________________________215 hp (160 kW) @ 5700 rpm (67.2 bhp/liter)

 Torque (SAE net) __________________________________________________ ______229 lb.-ft. (310 N•m) @ 3000 rpm
Max. Engine Speed __________________________________________________ ______6000 rpm electronically limited

Just gimme the facts man, 6,000 seems about right.

That is the truth! That is why I don't feel bad when running up against a Mustang GT or any other American muscle car. A couple second faster on a 0-60 but big deal. They may get that quick boost but they can never keep up on the highway. The Crossfire keeps up real well then I always blow past them and the Crossfire just keeps on accelerating while they have no power and have to slow down.

Perfectly "stock" 6 speeds are supposed to run high 14's according to Road & Track magazine road tests. Of course these are professional drivers in ideal conditions. Automatics are supposed to do around 15.2.
CAI's have been documented to cut ET's by as much as 4/10's.
My guess is you just need to learn how to launch your car, and practice your shifting.
Power shifting is recommended for best times, but not for drive train longevity.
Installing 225/50/16's on the rear can cut as much as 3/10's just by having less rotating mass.
With an 04, you can disconnect the traction control, and you won't have the pesky computer interfering with wheelspin.
My cars computer has never been tampered with, and the rev limiter doesn't kick in until I hit 6 grand if memory serves. (I'm talking about going thru the gears, not in 6th. gear top end RPM's). I've never tried top ending my car, not a wise thing to do IMO.
Good luck, and have fun at the drags.

where do you get the 186mph "fact" ?

Many people are not willing to risk going 140 around even a slight curve, regardless of how well their car handles (or is supposed to handle). So just because you did it and the Viper didn't, doesn't mean the Viper couldn't. The guy didn't want to, or didn't know how to drive it at that speed, or both. The same goes even for straight line runs. Just because someone smoked you to 120 and then you pass him at 140 (when you think he ran out of power) doesn't mean he couldn't have kept pulling on you ... more than likely he figured he made his point, and anything further was simply risk (wrecks, cops, etc.), however slight, for no reason. The Crossfire has relatively poor aerodynamics from what I've seen, and it doesn't have gobs of power (especially n/a) so why would it pull on cars up high when it can't down low?

Based on my experience with my 2000 Camaro... it handled great and had power. Once you hit 100+ MPH it just didn't seem like it could stay up there that long. It would corner on rails and get up there pretty fast. But once I started driving the Crossfire I noticed a big difference. The Crossfire would hit 100mph and want to keep going. Almost like it enjoyed going that fast and wanted to move faster. The Camaro felt like it wanted to slow down. Didn't feel as stable at 115MPH.

The speed/times should come as no shock (and subsequently, no knock) to you.

Last time I checked, staying in my throttle for 14 seconds would land me a hefty reckless driving ticket, if caught. So, it's fast enough for me

When I bought this car, I knew several things before even turning the ignition:
  • The list of cars that can beat me is roughly equal to the number of cars I can beat. So, choose wisely
  • 215 HP is not going to scare much of anything
  • 150mph in a bone-stock vehicle, on the other hand, WILL scare some folks
  • I would NOT be able to buy any other car with half the pedigree my Crossfire has, in half as good of condition, for the dollar I paid
  • I would be driving an eye-catching, extinct piece of automotive art.
What I didn't know:
  • I underestimated the amount of attention this car draws... You'd better be an extrovert
  • This car not only does 150 in stock form, but it does so magnificently. 150 never felt so smooth, and I've been there a few times in several different machines. Truly impressed.
  • The combo of a 6MT, cedar interior, and Alabaster more than makes up for the OMG acceleration of the SRT that I passed up... for me, at least. The only time I had buyer's remorse was when I tried to keep up with an SRT... but, when I looked down and saw 135mph, I realized that was just as fast of a trip to the jail as theirs was. All other times, I'm completely happy with my purchase. My combo is a rare one.... And a gorgeous one.
  • Don't even get me started on the attention this thing gets from women. My girlfriend is absolutely in love with it, too.
  • It is the most practical sports car I can imagine... I regularly observe 26-27 mpg, something I wasn't expecting.
  • It draws kudos from all age demographics... I get thumbs-ups from the elderly, winks from the cougars, attaboys from my peers, and faces planted against the windows from young eyes that are half the legal driving age.
  • It is, by far, the most comfy sports/touring coupe I've ever had the pleasure of driving.
So, there you have it. I passed up some $10K cars that were much faster, and also much more beaten-up. I sacrificed a little speed for a LOT of class, and a gem of a used car. I passed up a bit of raw power, and gained a TON of exclusivity.

And, I gained all the unexpected things I listed.

The mustangs can have their 13-second quarter miles... I'll arrive a few seconds later, after the smoke clears, and arrive in style.

After all... if you're important, they'll wait.

Thanks Franc.

Funny you mention that -- I now find myself doing daily grocery store runs, instead of the usual weekly ones I made B.C. (Before Crossfire).



Oddly enough, my visits to the gas station have increased as well.

Oh well, can't win 'em all...
