Default how fast is a Monte ss?

hey guys,

wondering if anyone knows what top speed is on one of these ls4 monte ss's... anybody know?

I know it's illegal but my wife and I took mine out to see what it could do on some nice flat even road at 7am with no traffic.... i figured 120 top.... but i was surprised in less than a half mile i hit 140 on the speedometer.... i quit then because no idea how fast i would be going after that... but it was still gaining... i personally think this is as fast as my old lt1, and close to my old ls1 T/A..........
anyone know what the top speed is rated on these things? mine is a 2006 ss...bone stock with 54k on it

just curious...

i absolutely love this monte ss, comfortable, decent gas mileage and all the power you would ever need

I think 140 or 145. I know with the limiter removed the GXP has hit 154, but it took him about 4 miles.

Ya i read somewhere the GXP were limited to 142-145 stock. But SS were like 150mph. Dont remeber where. So somewhere between 140-150mph. Which is odd since GXP's have the 160MPH speedo and HUD if we were to go faster than that.

i have had my gxp to about 159, but usually it tops at 153. I know though that the montes are faster than the gxp stock for stock. I raced one in mine before mine tune and he kept up pretty well, i was still faster but it wasnt a total kill considering i had a lot of work done.

My 2008 GXP did 153 with no programming, no limiter removal.

I was always under the impression that the Imp and Monte were good for 154. But I've never had mine over 120.

C&D I believe said the Impala is 154 drag limited, and the GXP was 143 electronically limited

here it is, 7th quickest of 2007, Impala SS, 9th quickest, GP GXP

Is it just me or does everyone else that owns a GXP get better than 5.7 to 60? Bone stock my best was 5.5... Oh well, the ISS and MCSS are nice cars. Sad to see them go, too. Great cars.

Stock I was running 5.7 0-60
With my mods it's 5.5 rolling onto the throttle slowly to avoid wheel spin. Maybe altitude explains the difference.

Maybe someday I'll actually be logging data during a good launch...

I video, then time the video and compared to the DashHawk when I had it. DashHawk was always fast.

Look at this video. This is also on an 07 GXP too.

Pretty damn fast if you ask me. Close to 160...

All you have to do is adjust your tire size in the tune to make it look like you are going faster, make a video, etc.

I've done 150 before but out in the country roads about an hour from where I live so I didn't have much room. I've got some nice long straights here on the highways but I don't want to risk going to jail!

Have you guys ever topped out 5th gear in a M6 fbody? Stock 3.42 gears. That took a long while and got scary towards the end.
