Hey guys so a few days ago I tried to top my car out its all stock+N&N drop in. I went 143mph.

I would like to know what everyone on has got and what mods they have. I am about to get the gm1 kit.

Hey I dont want to do this...a lot but hey its good to know

 

im all stock with CAI and exhaust toped mine out at 250KM/HR

 

Seats removed, sub, spare, jack...k&n, light tune.... 160+

but with all that in plus luggage and a 125 pound girlfriend I saw 151

gps confirmed for both

 

It should be able to go in the 155-160 MPH region no problem.

 

160+ is accurate.

 

158 mph only at maybe 5500-6000 rpm in 5th im sure if i stepped on it a bit more i could of saw 160. i dont wanna though anymore..**** scarey dotted lines become solid at that speed and tunnle vision mode is turned on.

 

If stock, your limiter is 155 mph... so 160 mph is not accurate and is just inaccuracy in your speedo.

 

I wonder if the limiter were turned off on a tuned car without a spoiler what the top speed would be 165, 170?

 

I've been at 145 stock

 

The car is drag limited, not computer limited

 

im totaly stock got 2 about 140 in a two or three mile straight stretch.... yeah tunnel vision kinda weird but awsome

 

last night i seen 152 just before i put into storage, im sure it would have went faster.........its pretty fkn fast

 

BTW, this thread is going to go fail faster than you can get to 150

 

Not totally true. The stock tune is designed to cut out at 158

Which it will do

 

you don't get tunnel vision from going fast, you get tunnel vision from prolonged high g forces, which you're not getting in a cobalt lol. cut the ricer crap. If you're truley getting tunnel vision while driving you need to see a doctor asap.

 

^^ ditto

 

Yea a 140+ is fast well has any one with a tune tried to top theres out?

 

154-155ish... Canned tune with high rise.

 

yes. sticking by 160+

 

same thing happend to me...just touched 160 and i got out of it..not alot of road to do it where i live to max it out. it was a rush

 

okay so not tunnle vision then but everything is blurry lol geez i didnt know how to expline it..either way fact of the matter is its ******* fast! lol

 

Try 140mph on dirt now that was scary

 

Da,m 160mph is nuts. I would think now that the the rev limter is taking off poeple with a tune would get 170mph.

how much dose the stock high rise slow are cars down

 

I hit 160+(needle was below the 160 by a little bit) in my old ss/sc, held it for a while at that speed, 5mins ish i guess?. It had full exhaust, stage2, intake. Car had fair amount of bags for my return trip home, my friend, me and his bigass dog(like 70lbs probably). Was pretty freaky, its amazing how much distance you cover in a short amount of time at this speed. If I remember right, I was at 80mph in 5th gear and just held the gas down the whole time in 5th gear. Took a while, but once you are in 110 ish speeds, the 5th gear has some power to it and starts too pick up in acceleration. To be honest, I still had some room in my rev's, but didn't want to try and push it any farther than the 160ish(most likely 160-164ish).

That was the last time I've ever done something so reckless. Too dangerous, one deer and i would have been dead. Not only that, most tires are only rated at about 130ish(unless you get real expensive). Honestly after I sold that car for my TC, I've been driving like a grandpa and babying my car .

 

SRI, bpv spring upgrade, vacuum tank delete, tune, rear cat hollow out, wingless, rear spare removed, coilover. hit about 135 mph, and got a little scared.
