Not bad at all. I've made about 15 passes in my LTZ sedan and this is my best 1/8. This was a full tank with junk in the trunk as well. 38psi in the tires.

Made four runs tonight. I was car 51.
Run 1:
.6221 RT

Notes: Up against a V8-swapped PT Cruiser. 40 PSI, TCS on (forgot to hit button)
Run 2:
.1998 RT
2.6803 60'
17.0682 @ 82.40 MPH
Notes: Against a C5 'Vette. No tire pressure change. TCS fuse pulled, but missed 3rd gear.
Run 3:
.2491 RT
2.5260 60'
16.5269 @ 85.40 MPH
Notes: Against a Plymouth Duster. No tire pressure change. TCS fuse pulled. No mistakes.
Run 4:
.3001 RT
3.2788 60'
17.8098 @ 84.28 MPH
Notes: Against a highly modified '13 Mustang. Driver redlighted, so I won! :banana: No tire pressure change. TCS fuse pulled, but failed miserably at launch.
Track altitude is 757' ASL. Ran with a '12 LT sedan, 1.4 manual. No modifications whatsoever. Even left the spare tire in.

Sonic is a 1.4L manual hatch with a K&N short ram intake (which seems to have increased my IAT's according to my ultraguage) and a turbo tech racing lower transmission mount .
I was gunning for 14's but it didn't happen, although I was quite pleased with my traps. Dragway 42 has a 900ft elevation iirc, density altitude was likely in my favor as temps were in the mid 50's.
My traps were rather consistent, was right at 95mph for a majority of the passes (made quite a few). Although after a few passes in a row my IAT's were in the 100-110 degree range and I started to slow down to around 93mph. Frustratingly I couldn't make a pass with ultraguage indicated IAT's below about 70-80 degrees. Am hoping to try to better insulate the K&N heat shield at some point.
What tune?

Same for me.
I didn't even request they give me the obligatory "free" first fill up when I purchased the car. I wanted to put 93 in it right away.
My traps were ~94MPH with crap 60's when I went opening day this year. Track elevation is about 500ft and DA was also favorable.
Hoping to return November 9th pending dry weather to see if my downpipe will net better traps and hopefully a new best E.T.

Get some slicks or drag radials and low 14's should be easy.

I wouldn't say easy.
Slicks won't help -I had no traction problems with my oem tires. Should be able to get 14's with a little luck -only 5 hundredths off.
Might try to better seal the k&n heat shield at some point if I have the time, I think lower IAT's would have gotten me there....

I have figured it up that with my sonic, every tenth I dropped off my sixty foot took about two tenths off my 1/4 et.
Lock out your rear springs with some form of drag bags, and sticky tires in the front. You will at least drop one to two tenths.

Went to Milan today. I was hoping for better, but with soft launches due to wheel hop and the shift grind rearing its head I was kinda slowed down a bit.
Saddly the best two runs were also the first two.
Milan Dragway
approximately 700' above sea level
Car #400
16.7837@83.83
16.7191@84.57
The car remained fairly consistent in the 83-85 MPH range.

I was hoping for better, but too many things were working against me to make it happen. Next year I will be looking to change the engine and trans mounts, hope that lower control arm bushings are available, possible get rid of this turd 5 speed (1-2 and 2-3 shifts show that there is a severe issue within the trans, probably the fork tips), and maybe look into some tires.
the few times that I tried to launch the car resulted in wheel hop. I had to bring it to just off idle and roll into it very slowly to prevent the hop. The shift grind was very irritating and troublesome. A few times I could not shift into second and a few times I could not get into third. No grind, just could not get the shifter to go into gear.
Overall, I had a decent trip there. Learned some new things about my car and started to prioritize what needs replaced to increase the chances of things not failing.

Mitdr774-what were you racing? Wow their trap speed was 122

Good job man, the motor/tranny mount combo will help get you out faster, and will also help reduce damage and wear to your drivetrain created by wheel hop.
Have you tried the footballs in your rear springs?
That may also help lower your sixty.
Great job again, alot of people may not understand why so many of us run our sonics at the track, but who cares lol
. There is no better feeling than working on your car and getting the results at the track, and even better beating all those people who laugh and say "Is that a sonic?" (Mustang owners) cough, cough

I know that motor and trans mounts will be a huge help. I think some upgraded control arm bushings would be a massive improvement as well.
This was my first trip to the drag strip with my Sonic. Next time I might try the football trick. My last car that I took to the strip had adjustable struts and I could stiffen the rears up to a very uncomfortable amount. This did help with 2.0 60' on ****ty RS-A tires. If I can get my 60' times under control this car might possible pull off a 16.5, maybe.
With the power I am supposedly making and the weight of the car I was expecting a far better run. I know that more than just weight and power are involved, but when a Cavalier with the same weight and similar power (140hp/145tq vs my supposed 160hp/130tq) can run 15.2@88 I have to wonder if the PID numbers are way off or not.
I think the future may only hold a handful of drag strip trips for this car. It will probably make far more Auto X runs than trips down the strip.
