Didnt relive it was a 2.0 forum till after i posted. Its in a 2.4

 

wow some of you guys are nuts,

 

Been about 140 racing a WS6. Since i went higher than stock trim I've had winter tires and I don't want to blow them up.

maybe they meant 270 at the crank?

 

148 mph .......... still going (like a turtle)

 

Heh, I did 140mph on the parkway this morning on the way to work.

 

The vid in here where I walk away from the red SRT-4 in the second run I broke the speedo by dipping it past 160. So I'd estimate 165-170 ish.

 

163 on cbr600 bouncing of the rev limiter in 6th

 

If you look in the gallery and search for "top speed" i uploaded a pic that i took with my cell phone of my speedometer going 152 MPH. It was stock at the time. https://www.cobaltss.net/gallery/sho...atid=newimages

 

When you say stock is that just a Cobalt SS/SC the way it comes? with 205hp?

or did you have the Stage 2 or something like that

 

I've had mine somewhere above 220kph, but I didn't look at exactly where it was, as I noticed i was doing 220 after I let myself start to decelerate..

That works out to roughly 136mph for those who don't know, or don't want to find out :P

 

183mph in a Porsche GT3 at the Neurburgring. My co-pilot (owner of the car) was actually telling me to go faster. I said no.

153mph on a CBR954RR on I-75 going north out of Atlanta is my fastest stateside. Haven't pushed the SS over 100 yet.

 

well since end of 4th gear runs out in stg2 at 143.2MPH thats what i did b/c around 135ish i passed a tractor trailer that was going like 60. ****** 60 b/c i swear it was like i passed a stopped truck at 70 kept it floored even when i saw him and then 1 second passes by and i pass by him fast real fast then reedlined it and let off. just imagine being the driver of the tractor trailer . next day passes by and my engines knocking then at the grand openig of a new dyno shop one guy tells me the noise is coming from the supercharger and dealership lets me know that they shipped a new supercharger since it was the bearing they've had it since monday and im leaving town monday and of course that is the day its gonna be fixed. im not gonna see the car till saturday when i get back. so y does it take that long for a supercharger to be replaced? damn they should of put it on sonc air or something

 

about 120ish on an entrance ramp to the interstate...on the curve of the ramp. Havent gone ***** out yet... too many pigs around my damn town.

 

I've gotten mine up to 140mph..havn't had the space nor the time to get it up higher then that.

 

when i had my interceptor's it read 157. with allmost 1k left in fifth.. my speedo goes to 140. and since stage 2 tune i can bury the speedo and the tack will keep going. i dk whats the absolute top speed of a lsd equipped lsj..

 

120mph in my 07 2.2 ls.. how come every other ls is limited at 105? maybe im wrong?

 

1880 Meters per Second.

That's 1.16 Miles per second or..

4205 Miles per hour..

 

Ok heres the top speeds in every gear assuming a 7000rpm redline
1 - 37
2 - 73
3 - 107
4 - 143
5 - 182

Problem isnt the gearbox as far as going much past 150mph, your main problems are drag and lift, if air density wasnt a problem we could all hit 182 with ease assuming the speed limiter was removed with HP tuners. Thing is at 150+ its like driving into a brick wall because there is so much pressure at the front of the car, if you have the horsepower and space then there shouldnt be a problem fulling running out the car. The other obstacle is the front end not lifting off the ground. Of course the only way to reduce front end lift is to increase front end downforce which will increase drag even more which will make it even HARDER to reach high speed, but you will be stable.

Personally I did my best the other day just taking it to 120 in 4th gear, I didnt have much of a taste for anything higher.

 

since i drive on the streets only, havnt been to a track..65-75mph

 

145 in here reached 157 down the hill right after the bridge
http://videos.streetfire.net/videos/...0SC/page_1.htm
i'm the car in the near beggining haulin ass under the bridge

 

hit my rev limiter at 125mph.

only 2.2's that DIDN'T come w/ the sport package that included the 16inch alloys are govern'd to 105.

 

158..nice spot of the freeway

 

145 in the balt 158 in my maro, had all of 6th left, and about 1krpm left in 5th.
