Top speed of a P5?
 

Anyone know the top speed of a P5. Bone stock with a 2.0 and 5 speed?

According to Car and Driver (Nov 2002), the top speed of a 2.0L LX sedan with 5-speed was governed to 117mph. I do not have the comparo with the P5 in it handy, but I would assume that it is the same because the powertrain (and thus the stock engine cal) is essentially the same. If you could figure out how to rewrite the code in the ECU so the vehicle would be redline or drag limited instead of governed, I assume it would at least crack 125.

Yep...it will crack 125 bone stock given enough road!!

good question, anyone know how fast a 01 protege lx will go? or atleist how fast it will go with the governor?

mine hits 130mph with ease but it is not stock. With a good 4-1 header and catback exhaust I bet you could run 130+ until you hit an aerodynamic wall...

i tested it out yesterday, and it would only hit 99MPH. i had it flored and it maintened 99 for about 10 seconds but wouldn't pick up anything else, so i was pretty dissapointed at that. so ill prolly have to do some mods to it soon

i got up to 110 and let off because i couldnt see over a hill incase of a cop

a hill??? in Texas?? I'm calling BS!!!


hahaha

i hit a little over 115 on the 10 towards tucson (sorta uphill). i'm not stock either.

Highest I've had mine is 115. Also with ease. Also not stock.

i hit 118 mph (190 kph) in my LX '00, pure stock. then it just let off. kinda pissed about that. anyone know how to take the governor off?

there is no governor...bone stock the P5 is usally drag limited to around 120

.... Car and Driver (Nov 2002) notes that the ES sedan is governed to a set speed of 117, but I suppose Macdaddyslomo could be correct about the P5.

For your reference, when a car is goverened, there is not a mechanical device on the engine that limits speed. There instead is a line of code in the ECU software that cuts fuel and spark when you hit a maximum speed value. It compares this preset limit with the output signal from the vehicle speed sensor. In order to change the limit value, you need to download the software from the ECU, and go in and change the code to a higher value. Set it much higher than the car is capable of going, and the car becomes drag limited (or redline limited in the case of a very powerful car).

Please also note that on an automatic transmission car, again the vehicle will be governed to a different top speed, as it will not allow you to overrev the engine. Even the best manumatics force you to shift just before you touch the redline in "manual" mode, so I suppose this could also apply to Proteges with the Sportshift manumatic.

Now this I will need proof! I tried it a few months back and all I could get was 105 mph out of my 03 LX sedan!
But it was VERY windy, and I do have about 100 extra pounds in my car with the system I have. But at 105 in 5th gear it was around 5k RPM so I don't think you could get to much more without readlineing it.


(a hill??? in Texas?? I'm calling BS!!! )

We have hills, and some are BIG too. But I have never seen a mountin.

I hit 115 pure stock in my dx 2003. Could not tell you rpm because I have no tach.
