Actually you are wrong, 10k left in lease, was 13k in total or trade in and be 10 grand upside down. I paid 15k for the srt-4, plus 2k in mods, will suffice for mid 12's, and pull over 9 g's. so that is 17k plus 13k hmmmm 30k? I could get maybe a used boxter for that and a early 90's m5. And the SRT-6 sucks, its an automatic. I don't do auto's unless its a lightning. And I have someone already interested, in assuming my lease, so 80 percent it will just be 17k. Not too shaby. which is what the crossfire will be worth 1 year or less from now.

BTW have you heard of the Extreme lightweight Neon.

the thing has 400HP to the wheels, and pulls 11's, costs around 32k, special order only from Mopar, also has only one seat lol.

anyways, congrats on your awesome new car. the seats are awesome i sat in one before.
Yes i have, but the stage 3 will put at 320whp in an otherwise stock neon, no bolt-ons, MOPAR tested this car on drag radials and it ran 12.2@118. ON slicks that is good for high 11's. And if I wait i can pick up a used stage 3 for 3200, and slap that on my 15k srt-4. Voila, you have a true beast for under 20k. Or if you wanted to go cheaper, just get the kit from apg for 1800, srt-4's are hitting 400whp on that kit. I won;t be going that far, just stage II and some bolt ons', no sense in voiding my warranty.

Or get an STi, awsome car. I just couldnt find one for the right price, and the right shape. If i did i would probably be driving that right now. Who knows with my track record, I may have one in less than a year. :-D

I didn't say it handles like a brick. I will make a correction, I mixed the terms handling and road holding in my previous post. First, let’s make clear what lateral g's mean. It's the centripetal force that the car can withstand before losing traction and going into a spin. It's not a pure measure of handling, because there is no way to empirically measure how a car "handles". So, the closest thing we can measure is how fast a car can travel through a turn without sliding. The Crossfire’s road holding numbers are equal to every other major sports car under $50,000, even the M3. The only car I’ve seen under $50,000 that has a significantly better later g is the Evo. Yes, a Crossfire can go through a turn as fast as an M3 without losing traction. It’s a statistical fact. Many drivers say that the M3 “handles” better than most sports cars out there, so it’s going to be quicker coming out of the turn and going into the next.
Here’s some math for you to make it easier to visualize how fast a car is traveling at a certain g force.

Given the following:
Acceleration=velocity^2/radius
Radius= 150ft (car and driver usually use a 300 ft diameter skidpad)
To convert skidpad "g" to ft/sec^2, multiply by 32 ft/sec^2.

So, the Crossfire pulls .91 g's in most tests. This = 29.12 ft/sec^2 lateral acceleration and a velocity of 45 mph around the skidpad.

A car with a .88 g skidpad is traveling at 44.31 mph around the skidpad.
A car with .86 g skidpad, like the SRT-4 in Car and Driver’s review is traveling at 43.8 mph.
A car with a 1g skidpad rating is traveling at 47.23 mph.

So, handling is a subjective term and the SRT-4 may indeed handle very well, but its road holding is lacking. We all know it’s horsepower that you care more about anyway, so I’m sure you’re very happy with the new car.

Yes, that 1.2mph, less in some cases but we will use your numbers, makes it an far superior handler? I think not, the crossfire may edge out the srt-4 by a bit in the turns, but the SRT-4 will make up for it and them some on the straight aways.

I would love to see a video of a crossfire pulling around a m3 in a turn.

The X3 actually pulls more g's than a M3 according to Motortrend, so that means the X3 a sav is a better handler? Please.

I hope that your SRT-4 can give you what your Xfire didn't. Good luck!

And dad yes the nitro would have been cheaper in teh short run, but not when I blow my engine in the process. And it would take as more than a 50shot of nitrous to hang with the SRT. Just can't wait to sell the crossfire, when I do its fox body notch back time.
Yeah, I'm 5'11" and with the Crossfire seat lowered its fine. You'll have plenty of head room in the SRT-4. It was indeed a ball to drive. I don't think the Crossfire has a lack of power, I'd call it slightly reduced power. I do prefer the ride and handling of the Crossfire over the SRT-4.

Good luck with it...

I'd lean more towards the fact that the car can get out of its own way, unlike the crossfire.

I'm sure your dual exhaust setup added 50whp though. Thumbs up. And talking to me about rice.

Nope. But it LOOK's like a Neon. That's enough to kill it in my book.

You're criticizing dual exhaust now!??? Shows how much you really know about car performance. How do you equate that with Rice????

It doesn't look that good, I have seen those exhaust tips on a great deal of hondas(such as the dual exhaust setup on a Si) and you have two of them, I appreciate what you were trying to do, but should have customized the Tips that come stock, and it would look great. Rice is something done cheaply to get some performance, like cutting your hood for more air, or making a choppy exhaust. Or something that is just for looks and gets no performance.

And how do you know it added hp? Have you had it dynoed? That is the only way to be certain.

Why did you add K&N filters; to allow your engine to breath better;
Why do you change to dual exhaust rather than single; to allow your engine to breath better.

I have never claimed any h.p. increase because numbers don't mean that much to me; but I do know that the engine performs better, feels stronger and breathes better.

You're the one that mentioned 50h.p. gain so it would be better to stop putting words in my mouth.

Have you ever seen a V6, V8 or V10 race car with single exhaust; and I mean a race car such as NASCAR, IRL, CHAMP CAR, FORMULA I; and don't get the idea that I'm trying to emulate one of these cars because that is not the point.

Just think about it. Also, I really don't care if you don't like round tips, I DO!
If I wanted the rectangular stock ones, I could have done that too.

What ever floats your boat, the 50 hp remark was sarcasism. It would look okay but I keep on staring at that big gap between the tips, reminds of a someone's teeth that should play in Deliverance.

I added the kandn's because I do in every car I have owned, sometimes I feel a difference, but one thing is consistent It always gets me about 1-2mpg better. They pay for themselves. And at 26 bux a piece? Why not?

Lauren Hutton looked pretty damn good with that gap between her teeth ... and she just happened to be from the same state where Deliverance was filmed ... South Carolina.

Default Re: I finally did something about the performance of the XF

This is an interesting post, and everyone has great ideas and opinions...so here's mine: I bought the Crossfire for it's looks, it's style, and because it was the only 2 seater from DCX that I could afford (right now...I'm still working at the Viper). I'm pleased with it, although I must admit that I would like more punch. But since it sits at the airport in Atlanta most of the time, it suits my needs just fine. For performance, I have a 1973 Plymouth Duster with a Mopar Performance short block and Edlebrock aluminum heads, ported and polished with several other upgrades. It's not really streetable (nor is it street legal) but I do take it to car shows and cruise nights occasionally. Best time at the 1/4 Mile track (Silver Dollar Raceway in Reynolds, GA) is 10.96 at 127.55 MPH. 0-60 in about 3.5 seconds. So when I feel the need for speed, I know where to go...but when I feel like cruisin' Chrysler style...the Crossfire fits the bill perfectly for this 49 year old Mopar nut. Enjoy your ride....whatever it is!

Oh I forgot to mention there are plenty of srt-4's on e-bay If anyone needs a beater. I think I would feel safer in xfire at 120 mph. and yes I've had it there plus. the aero dynmatics are better.

Top speed is over 150mph just like our crossfires. Had it up to 110mph, stable as can be.

The srt-4 comes with better rubber stock than our crossfires do. Just some fyi. Who would have thought.

And anytime you want to put your crossfire vs my crossfire or my srt-4. Let me know.

I guess the ricers live you alone when you cruise in that Duster hah !

Hate to burst your bubble but there are more XF's on ebay than SRT-4's.
