Same here I feel a resistance at 125 mph but since I got the turbo on I would say I can probably get it up to 135 - 138 mph if I push it but I won't bother.
Those speeds are insane and I would not recommend it unless you upgraded the front and rear brakes, suspension, wheels, control arms, sway bars .......................................

 

I dont realy want to go that fast i just needed to know for a driving compitition i am entering.

Wait so you maxed out at 77 mph? I think i can go like 75 ish in 3rd gear but i have the 5 speed. What set up do you have that limits you to 77? cuz that seems kinda slow. I have had mine up to 95 on the flat desert road to vegas but never wanted to attempt anything faster then that. because at 95 I felt that if some one cut me off i might rear end them.

 

ya, i would not do that again on stock brakes...took everything i had to slow the damned thing down...
was a rush though lol
had the moto up to 125...that was crazy out in the open and all lol

but i did this on upgraded tires, lowered, strut bar, and driver mod lol

 

does anyone know what Bridgestone potenza pole positions are rated for?

 

168 MPH (270 KPH) if the letter after your tire size =W.

don't do that

 

i take mine in between 115-120 on a weekly basis

with a 3.4% speed increase because of tires

so that is 119-124

handles good at those speeds too with the 245/40/18s

 

I have a 07 ls Ive been 114 before it cut off in mine, I have steelies and ive hit it a few times none were races and I live in the country so I dont worry about the police much

 

08 tc stock will go 140 with room to go. just ran out of open highway had to slow it down. wouldnt do that near other cars.

 

wrapped it past 120...guessing about 125...Still in 4th

 

I10 for me and watching a supra turbo racing a lambo pass by me at 150- 160 ish lol

 

136 next to my buddies stratus r/t on 96 west in michigan haha

 

145ish on I10 at like 12am running around with other local cobalts

 

sometimes i got 83 on the freeway.
just dont tell anyone !!

 

My tires are rated for 170, not that I'll ever go that fast. Well, maybe after a few years.

 

Please preach elsewhere.

My balt with the turbo tops out at 135 from the limiter. I talked to hahn about this, and they told me to hook up a toggle switch that turns off my speedo. This has worked on mine.

On my wifes stock (minus my old injen intake), hers hits 115~118.

 

Hey, do you have slips or vids of you 13.3? Ever been to the dyno?
