How to disable top-speed limiter?

KillerBee370 · 08-12-2011, 12:28 AM

I'm still in for what track a stock z will run 155?? Unless I missed the answer somewhere?

My z is full bolt ons with tune and lightweight flywheel etc. and I was only able to get to 140 on the front straight at Auto Club Speedway.

For now I'm calling bs

none, FIA long banned the use of extreme long straightaways. I believe the limit is a mile or something

Was this a result of the '99 LeMans race with the Mercedes flipping? I remember they added two chicanes along the Mulsane straight at LeMans the year after that took place.

Technically you have to do 0-88 in order to do it in negative time with the flux capacitor!

nope, chicanes were added in 1990. a peugoat in 1989 did 250mph plus during the race. fia doesnt sanction any tracks that have straights longer than 2km. it used to be 5km long.

i would assume road america or daytona are the two places that you might crack 140 legally if you are lucky in a stock z in the us.

I have reason to believe that, all aren't set to155 by default trust me!

As others have said the limit can be removed via an ecu upgrade.

With the limiter removed you are looking at around a 165-170 top speed depending on road conditions (wind, grade, etc)

For the guy who asked you can hit 155 in 5th gear so he probably wasn't in 6th.

well said.

As a consolation, the 911 driver might also be sick of seeing the rear of another brand if car.

Ps
In a Porsche forum, a rich HongKong kid posted a race challenge with him driving a modified Japanese non-exotic car. It created a bunch of chaos but no one took the challenge. The common comments: "someone will always be faster than you. Learn and accept that fact."
