155 mph
 

is the z car limited to 155 mph by the computer because of the tire rating or other reason or is it all that it will do?

I believe its Drag rated Max.

156 was the limiter on my 11’ till I had it removed.

I hope this are not the question an 18 year old asking while on the steering wheel of a 370Z.

I'm not referring to you OP. I just wish you have a reason for asking that and you intend to do it in the track and not on the street.

The later question scares me.

remember what happened to all the 350z forums 5-6 years ago? winter is coming :rofl2:

The Z is limited to 155 with the ECU and by aero drag. To eliminate the 155 ECU limit. You have to use Uprev or Etec. Mine is reset to 199 mph. Will it see it? I don't think so. Unless it's dropped out of a plane. With the ECU limit removed. You will be lucky to see 145 mph stock.

In Florida if your caught at 110mph speed I believe it's considered a criminal offense, jail time is a big possibility and the 145mph speed you'll ever see and experience is sitting behind the patrol car. Lol

In Pa. Anything over 26 mph over the speed limit gets you 6 points. That's a written test the first time. The 2nd time for 6 points. It's a hearing $$$$$. 31 mph, spread your butt cheeks. The state is going to stick it to you depending on how many points you have already.

i hit the limiter (156) while stock......on the drive home from buying it :driving: (in mexico of course)

or you get a nice cop lol statey popped me on the turnpike at 99 in a 55 but just wanted to talk about my car for 15 min then told me to get home quick the pens game was on in 40 min :bowrofl:

Yeah, the 155 is an ECU limit.

I've heard the mechanical limit (redline rpm + gearing + wheel size) for some models is right around 200, but you'd need more engine grunt to get there. The aero of a 370Z produces downforce as well, so they get heavier the faster they go...

To provide "other reason": Insurance. The capabilities of a vehicle play into how much it costs to insure. If that gets out of hand, the market dies (see Pontiac Fiero).

To provide an example: nearly to a vehicle, 18 wheeler tractors are speed limited. It isn't that a modern truck can't do over 100 pulling a trailer, it's that they're speed limited, sometimes to as low as 67. The reason is insurance. There is a trucking company that tried to buck the trend: Swift. And they were. Operating without governors, they could deliver faster than other truck lines. But within three years of operation, insurance costs forced them to install governors and now they go the same speed as the rest.

hmmmm guess i shouldn't tell my insurance that my speed limiter in the car is now set to 999......

:wtf2:

The Tale of the Fiero
 

It occurs to me that many members may be too young to recall the story of the Fiero. The Pontiac Fiero was a compact sports car, laid out in a MR format. There was a 4 cylinder (2M4) and a 6 cylinder (GT).

The Fiero, like the Toyota MR2 was referred to as "the poor man's Ferrari" in reference to the MR layout (most Ferrari's are MR layout).

The MR layout can easily provide oversteer, making it an excellent sports/racing platform, but similar to the RR follies of the 1980s turbo 911s, all too easy to wreck.

Insurance costs on Fieros went through the roof as inexperienced drivers wrecked them with regularity and after a five year run, the model was ended.

PS
And for those making the connection, the Toyota MR2 also has a well-deserved reputation for crashing due to overdriving.

PPS
While I could see a MR or RR car as a plaything (Alpine 110!!), I would never have one as a daily driver as you would eventually have a slip in attention and get bitten.

Wasn't the Fiero the car that was known to burst into flames when rear-ended at low speeds?

I thought that was the Pinto?

Maybe you're right. The Fiero would be so much more aptly named though :icon17:

True. LOL!

The Pinto was the fire bomb.

The Vega was known to use more oil then gas. The blocks in them was very porous. Leaked oil right through the block. Chevy had one Vega. The Cosworth Vega. It had a motor developed by Cosworth. It was advertised as one Vega for the price of two. It was double the cost of one Vega. $3,400 vs $7,000

The Chevettes was noted for the bolt breaking that holds the crank damper in place. This let the damper walk off the end of the crank into the radiator. Taking both the radiator and crank out.

The Fiero was made from 2 cars. The front end/suspension came from the Chevette. The rear end/suspension came from the Citation. Low sales and Chevy high management is what killed the Fiero. Chevy hated the Fiero. They thought that it would take sells from the Vette. :rofl2: Pontiac management had their hands tied when they was developing the car by GM management.

Then came 1988 and a redesigned Fiero Chassis where they finally got it right...it was a one year deal and the car was axed for 1989. The '88 Gt was actually a pretty good car, and you can directly swap in the larger 3.1 motors from later GM cars for 200+HP in a 2600lb car. Darn good for the day.

Regarding 370z top speed, I have to believe that much over governed speed is going to cause you to redline....I've been up to 125 on a deserted piece of freeway a couple different times (yeah, flame on....) and she was north of 5500RPM already.

This thread just went from a young kid asking about the speed limiter all the way to a senior citizens discussing about a Fiero and a Pinto.
Nice!:icon17:

Thank goddess Im still hooked to porn!!!
Just turn 25 a month ago.


But I started lying when I was 5 years old.

Hey, at least we can talk about Pintos, Fieros AND porn without help from history books. Errrrrr, I mean the interwebz.

Hold on, Senior Citizen? whaaa?.. I'm still in my 40s young man!!!

My ex wife had a Vega when I met her. She told me the dealership told her she never needed to change the oil, just the filter every once in a while. They were right. I had to add oil so often it was always new.

This thread went sideways fast. About 155 mph fast.

You are old. (at least for people under 30)
I’m 41.

We called the Fiero the “Fire Arrow”.

For sure....it was!!

I will attest to the MR2 wanting to swap ends , mostly in any damp or wet conditions! Dry I drove it to the limit never a worry, you knew from your seat where the edge was.


Rusty... PA is $$$$ no matter what the ticket is!:rofl2:

I think OP got spanking from his parents for asking that question he never did come back to this thread. Lol

Wonder why.

You do now the history. :bowrofl:

:rofl2:

My 1st wife had a Vega when we first met. It was check the gas and fill the oil. she had the tranny fall to the ground twice. The bolts that hold the tranny to the engine would never stay tight. The local cheby dealer was eating this big time. :rofl2:

Yep, they got it right in '88. Only to kill it the next year. :shakes head: For awhile. The Fiero was the king of kit cars. Pop off the stock body panels and screw on almost any other body style you wanted. :rofl2:

from what i have read and seen at stock it runs out of go not much over the 156 limiter. Somewhere in the 160-170 mph area

I know that pushing into a 30~ mph head wind you need a lot of track to break 130. I tried over and over last fall at No Fly Zone and with pushing into that much head wind 130 was it no matter what i did for a launch. I did 25-30 runs, 30-60 rolls(1/2 mile after the roll start) many digs and even backed up to the end of the runway once and every time i was 127-130 at the trap. Fingers crossed for better weather over fathers day weekend this year.

Glad you respect your elders.

I've been around the bush once or twice.

You are all a bunch of old *****

You missed a bunch of fun cars to have at cheap prices. :driving: :rofl2:

:wtf2:

Yep, I'm old. And wise. And stuff.

But being old, I paid cash for my Z :tiphat:

No lie,

A friend of mine bought a 1988 Fiero yesterday for $400.

Why....
