Took the XFIRE to the local 1/8th mile track set up in the Qualcomm stadium parking lot here in San Diego(where the Chargers play football) last Friday night. The car is a bone stock Autostick, here are the results.

1st pass: 9.9 @ 72 mph 2.43 60 foot (traction control off)
2nd pass: 10.2 @ 71mph 2.59 60 foot (traction control on -car bogged under load at start)
3rd pass: 10.0 (no mph recorded) 2.42 60 foot (traction control off)
4th pass: 10.0 @ 72mph 2.47 60 foot (traction control off)

the track conditions were terrible, the car spun the tires bad. I can't spin the tires on the street! The car did not like launching hard (full throttle romp) with the traction control on, it damn near stalled and equated to the slowest launch(see 2nd pass) the other passes w/traction control on resulted in significant tire spin. I did beat an SLK kompressor twice and a early RX7. The sole loss came on the 2nd pass against an AWD Subaru WRX turbo wagon. Giving up over 3 tenths to it in just the first 60 feet(it went 2.1 60 foot) pretty much summed up that race. With some more experimentation and a good track surface this thing could go 2.2 or maybe 2.1 in short times which would put it in the high 13 second 1/4 mile neighborhood... faster then I expected. 8)

 

Did you burn your tires first? What were your tire's pressure? Do you have the all-season tires?

Road and Track tested the Crossfire to a quarter mile of 14.9 seconds, and a 0-80mph time that fits your time well enough. I'd say that's a good indicator. Their test was with a six on the floor and the performance tires.

 

i am all about 1/4 mile.....1/8 mile blows :wink:

all magazines run the 1/4 for the true measurement of speed.

 

road and track got the crossfire to hit 60 in 6.4, and run the 1/4 in 14.7, bye using a "4200-rpm drop-clutch launch"

 

well that's the only kind of launch I'd ever do if I were racing.

 

wow, those 60ft times are horrible. i know you said the track conditions werent great. you should be able to get at least a 2.2 60ft time once you get the lauching technique down and the track conditions are better. but theres no way a crossfire is going to run a 13 second 1/4 time. the best i have seen in any magazine is a 14.7. anyways, good luck next time. make sure you keep us updated if you go again.

 

I hear ya but more and more tracks are going to 1/8th mile for cheaper insurance, ease of sanctioning and less real estate required, at least around here.

James doing a burnout with low profile radials is not desirable to a good launch most of the time.The tread on the tires slings water into the wheel wells which falls back on the tires and the track. Those tires just don't have any give in the side wall and are not designed for drag racing. My launch prep was easy, I drove around the water box and just stabbed the throttle on some dry pavement to clean the tires off. I have the michelin tires, I assume they are all-season?? I did not mess with tire pressure as I don't think there is much to gain there with the type of tires that are on this car and I also was not being that scientific just having a litle fun with the wifes car.
My first thought/estimation on 1/4 mile time was by using the old rule of thumb of adding 4 seconds to your 1/8 mile time so 10.0 would equate to 14.0. it works well on my 73 Duster which runs 6.80 in the 1/8 and 10.60 in the quarter. I just found the 1/8 to 1/4 calculator and it shows 15.7 for the 1/4 :shock: the car is faster then that so splitting the difference at 14.7-14.9 seems reasonable. 8)
