Seattle CTS-V

Finally got a chance to get out to the drags 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 ????? (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. I think he was pretty frustrated as well.

Didn't see you there Tom. I was there in my SS and saw the M-5 but didn't see your Caddy. Glad you got some runs in. My 1st N/a time was slow as well so I ran the N20 the rest of the night. Even though it was hot as hell the car ran very quick with the nitrous. I think on a cool day I will be hitting the 10 sec mark.

Last night was far from ideal. I only managed a best 12.85 at 111 mph in the 02 Z06. My last time out I was running 12.6's at 113. The right side was also real slick on the starting line. My best 60ft was a 2.026 with track temp of 116. Last time out I was cutting 1.9's. I even sat out for an hour and a half to try and cool down but this had next to no effect. I was also pissed at the track officials. They let everyone drive straight through the water box. On roughly one in every four runs you could see a trail of water from the box all the way up to the start line.

Last night conditions were fine if you were interested in bracket racing but if you were going for time it was a waste.

Your MPH is good for 12's, you just need to get your 60ft times down. Once you figure that out, you'll be running consistant 12's. I had a my Vette back in the day when it was only H/C setup running high 12's @ 113mph due to my bad 60ft times. It took me 3 years to figure out how to get low 60ft times. But I'm not a great driver either.

Keep at it and get some stickier tires and you'll be pleasantly rewarded.

I saw your car in the lanes and noted the wildly different times of the M5. In spite of the warm conditions, the crowd was the smallest I have ever seen. It's hard to enjoy the event when your car is not performing to expectations. However, I think you are making the power, you just need to get it to the ground.

Last year I ran 12.8-12.9 @ 115-116mph all night long. It was early spring and temps were perfect. 116mph should be good for 11's if I just had a bullet-proof rear diff and rear setup that wouldn't bounce all over the place like a rabbit on steroids. ...and I'm not the best driver either. The first two runs I nearly bogged the car when I let out the clutch.

I'm not sure why the M5 had such inconsistent times. Afterall, the 7 speed SMG in that thing only requires a flick on the paddle-shifter to change gears...how hard could that be?

you'd have to have some low 60ft times to hit 11's with 116mph traps.

I have to launch my car at over 5500rpms to keep it from bogging! Are you running stock tires?

Im gonna go out on a limb here an say your on street tires because those 60ft times look very similar to mine What kind of tires are you running on? Im on 275-40-17 Kuhmo Ecstas an they're great for street use but really suck at the track. I think you should definitely invest in a good set of DR's an keep the wieght of your car down. I bet you'd be much happier with your times

I'm running Goodyear Eagle F1 GSD3 in 275/40/19. They were on the car last year too. Another person reminded me that I didn't have the Ground Control coilovers last year. I'm running rear springs that are 150lbs stiffer. That could be killing my weight transfer and really helping to kill my 60'. Doesn't explain the low trap though. I'm still going to blame the heat. I think I need to get the car dyno'd to see if I'm making the kind of power others are w/ the same setup. I know all dynos are different but it should give me a general idea.

I'd definitely go dyno at Turbo Tech. With your mods you should be at 400+ rwhp. Who did your tune? As for the 60', I wasn't able to get sub 2.0 60' times until I got the Nitto DRs. Launching with IRS can be tough.

BTW, post your best run in the Run What You Brung thread and I'll be glad to get you on the list.

Turbo Tech, eh? That's in Tacoma, right? I "should" be at around 440whp/400wtq with my mods and tune. I got a mail-order tune from a VERY reputable and respected tuner on another forum. Track-tested speed density. It's always possible that the tune is off for MY car though...

I'll post over on the RWYB thread after I get back into the 12's

Yep, its right there in Tacoma-You could talk to Ryan K or Robert56, as there both locals there. They should be able to help ya out. Ellis can help ya out with tuning to if that ever becomes an issue for you
