Finally got a chance to get out to the drags at Pacific Raceways to see what the addition of the Kooks headers had on my 1/4 mile times. Last spring I ran a best of 12.8 @ 116mph with the 2.8 Maggie, Magnaflow exhaust and StealthV tune. Since then I've added Kooks headers, a K&N filter and a retune. I feel that I'm also a much better driver now as this is my first manual transmission car and I was pretty bad at driving fast the first few months.

So...last night at Wednesday-night-drags I went out to try and get into the mid-low 12's. I got to run four times (60' - 1/4 - mph):

1. 2.369 - 13.381 - 110.82 (beat a nearly stock SRT-4 (14.3@94.38))

2. 2.282 - 13.195 - 111.72 (lost to nearly stock '01 ZO6 (12.7@107.22))

3. 2.277 - 13.096 - 111.93 (beat a nearly stock VR4 (14.8@97.94))

4. 2.342 - 13.281 - 112.93 (beat a stock '07 M5 (14.9@108.84))

I spoke to the guy in the M5 quite a bit through the night. He was running almost identical times to me on each run (ie he progressively got faster through the night.) We were literally w/i a tenth of one another all night...except the time we lined up against each other. He said he accidentally started in 2nd gear. My 3rd run was my best and beat his best by one-hundreth of a second. He was also trapping 110-111.

So...I am disappointed in my times but feel sorta ok about it since the M5 was also running really slow. The first run was with a 92 degree outside temp and the final run was at 75 degrees. Unusual heat for Seattle and this time of the year. I also had my sub box, golf clubs and a 99% full gas tank. That's probably good for over 200lbs of extra weight. The ZO6 said he normally runs 12.5@110ish. There was a 5.7L GTO running low 14's all night.

 

Nice times...nice whip. I know this is your old stomping ground..but I'm sorry to say this is not CTSzine

but in all seriousness nice car and setup. Good luck with it.

 

beat m5?? nice story!!! lol

 

Were you spinning? With a rwd, you can def get those 0-60' times lower, which should result in the 1/4 times you are looking for. What is the ideal 0-60' time for those cars?

 

I think 2.0s 60 foot times are possible with street tires with a perfect launch. This car just doesn't like to hook up with these 275 rear tires. 295s might do the trick.

 

You do know he has a CTS-V with a supercharger, and not a CL-S, right?
