Anyone? Weather is getting nice. In the spirit of friendly competition, my Cruze runs 15.7 @87 mph consistently in the 1/4, and 10.1 @70 mph in the 1/8. We had someone hit 15.2 @ 89 mph as our best time! Of course, these were all tuned Cruzes!
I thought the Cruze and Sonics shared the same engine/tranny. If both cars are tuned then how is the Cruze is faster to the 1/8 but slower to the 1/4?

Someone's times are off there. You cant go slower speed and have a faster time. Or vice-a-versa. Lol

Wouldn't a faster speed = a faster time????
Or
a slower speed = a slower time????
Or
a slower speed = a slower time????

I ran a 15.8 with my Sonic without prepping the car for the track at all. Just a tune.
My ZZP intake was broke at the time so I didn't get to run with it. I also had about 50 lb of crap in my trunk + spare tire.
oh yeah and the hard stock tires where at 38psi so they were spinning like crazy off the line.
I'm hoping to get it down to at least a 15 or high 14 next time.

And the RT was???

also a dinner prick
When my Cavalier had a turbo on it I pulled off a 13.9@103 followed by a 14.5@109 a weekend or so latter. Its easy to post a slow time but high trap speed if you screw things up.

1/4 mi: 15.62 sec @ 98.3 MPH
Bringing up older post because im curious what a stock sonic 1.4t runs?
and btw just because you have high mph doesnt mean you go faster in the time, it just means you can get all those ponies planted fast enough hence your 60' thorugh 1/8th mile time

There a few ways to mess up a drag strip time.
1) Too much wheel spin.
This is seen in how slow your 60 foot time is. His 60ft happens to be 2.9, that's terrible, even for street tires. 2.0x is possible on pure street tires but you really have to learn how your car behaves on street tires when attempting to launch it from a standing start.
An easy way to do this is getting some type of measuring device and practice getting your best 0-60 time since that depends on getting a good launch and it requires a 1-2 shift to get it.
2) Fooling around on street tires.
Regular non-performance tires have such a narrow temperature operating window and hard rubber carcass that getting a good launch will depends on other factors like suspension tuning, chassis squat, alignment and how aggressive you are off the line.
I just don't have the patience to get a good launch on street tires since I don't street race.
3) Slow Shifting can affect overall time by up to .5 second
Add all these up and it leads to slow 1/4 times. 98 mph is just an indication he is making a fair amount of power, but it also tell me that mid to high 13's are possible if he can get the power down.
I don't know if I will get a Sonic or a Fiesta ST at this point, but both cars are capable of 13 second ET's, given enough traction for the ST (stock dyno is about 177-179hp, 197hp flywheel) or enough modifications to the Sonic.
The stock 15" wheels you can run a 205/50-15 BFG, Nitto or Mickey Thompson drag radial or 23x7x15 M&H slick.
The slick is worth at least 2 tenths over the drag radial. Cost is roughly the same. Drag Radials can be driven on, so you can bolt them on at home and not worry about leaving your jack and tools in the parking area.
A good 2nd gear burnout should clean them off and give them a good heating up. Caution; 2nd gear burnouts puts the best temp into drag radials and slicks, but its harder on your clutch.
I wanna see more of these cars run 13's!
