Only goes 85 mph. The speedometer only goes that high. Why is that? I feel like it should go a lot faster.

The reason is that the speed is limited to 180kph via the ECU.

Also, these cars in there day to day lives were never really meant to hit 90+ mph atleast in N/A. In europe/asia in some places the GT's came with 120mph speedometers.

and the 89 canadian GTi goes to 140km/h. they changed that in 1990. it's only a gauge, the car goes faster than that.

You'd think with all them straight roads out in saskertewn you would have had your car well past that, I've had my GT up to 205 km/h. Of course it was high altitude, I'm sure it might even hit 210 or 215 with a little more oxygen in the atmosphere.

I have had mine on the trip needle and ran out 4th and was doing about 6000rpms in 5th. It clicked against the trip needle faster and faster. Then i realized i wasnt driving on the road any more i was kinda skipping or floating down it :mrgreen: . I had the 3.78 geo trans though and about 18-20psi to help pull it.

Both Jr and I have had ours past the end of the speedo as high as 108mph according to my GPS.
never had speed cut, and my car is an 89 with the lower top speed speedo.

:lol:

Fastest I've ever dared to take my '98 was up to 160kph... and it does have a limiter at 180kph... :lol:

Also, most of these straight roads have holes bigger than a GT in them that'll eat these cars for lunch as the suspension gets chewed up and spit out on the opposite side of the road... :buzz:

Where did you come up with this speed cut thing? My car is all 99 16v electronics, no speed cut. If you have only had yours to 160 how do you figure it cuts at 180? Mine hits the rev limiter when it has 4.39 gears in fifth, but that's way past 180 and has nothing to do with speed, just rpms.
For reference sake, most cars when equipped with a speed limiter are set that way due to the speed rating on the factory equipped tires. Likely a liability thing?

Hmm...

Guess I got some stuff confused. There are 180kph limiters out there and installed on many cars.

I mean, every JDM car has a speed limiter installed/coded into the ecu, and many cars just have it carried over. I mean watch top gear and a lot of those cars are 'electronically' limited.

So.... meh... still no good reason to ever wind out any of these cars like that on a public road, and most of these cars will never hit 180kph in the straights on a track... :lol:

the speed registration on the speedometer has very little to do with the ability of a car to exceed the instrument's indicated velocity.

i was an instrumentation expert in my earlier days, ages ago, when digital technology was in it's infancy. all mechanical guages are designed to indicate most accurately at the midpoint of their registration. if your nominal average speed is say, the federally mandated 65 mph, theoretically, the high reading of the instrument would be 130 mph or twice the average indicated velocity.

the era in which our beloved machines were built with fuel economy in mind, they were pushing 55 mph as the most efficient rate. the designers went with the governmental mandate and dropped the speedo registration to 90 mph (85 in numerals with another hash mark above it for an extra 5 mph.) personally, i think that it was some mind game they devised to make it appear that anything above the oversized 55 numeric was in the danger zone.

anyway, with regard to design and engineering on an analog gauge, operating it in the middle of it's scale gives the highest accuracy and linearity. old school stuff. :wink:
