Inaccurate speedo

Every one. Limited by the Japanese government in the original case, they don't change the computer for NA. About 185 kph. And yes, it is impossible to go over 112 mph in any Honda recently made (meaning the last 10-15 years). And it is a combination, a rev limiter in fifth gear keeps you from reaching any speed over 112. And yes, that includes the Accord.

And mike, you seem to be challenging me in ever post...challenging the new guy??? Not that i mind....i like a challenge

Do you have a source with that fact? It is not that I don't beleive you, it just that i'm trying to prove my friend wrong. He said he went 135 on his accord.

To be more accurate, I'm challenging the "wrong" guy. My personal experience directly contradicts your statement about the max speed of Honda vehicles.

[911GT2]

It's a Japanese government regulation. Just like the rule that high powered cars must be rated at 276 hp, no matter what they actually dyno at. And for the guy who said he went 135 mph in his Honda, it's entirely speedometer innacuracy. I also have a friend who went 195 kph in his Civic when it's actually limited to 179. Speedometers are made so that at legal speeds, you can accurately tell your speed to avoid ticket problems. That's all.

And btw, i'm not including bikes in this statement, if that's what mike is talking about. And without it being chipped or having the rev limiter removed, 112.

I'm 100% sure a bone stock NSX directly out of the Tochigi plant in Japan could prove you wrong in about 15 seconds.

Too bad I can't prove it for you myself, but I don't need a third ticket.

[911GT2]

Here the NSX isn't a Honda, it's an Acura. Technically, i guess you're right, but that's not your everyday Honda. Remember that this question was originally about an Accord....not exactly an NSX.

[Jay!]

All Acuras are Hondas. You said all Hondas. I'm sure the S2000 (a truer Honda?) could do it in a little more than 15 seconds, too.

As soon as I said it, I bite my tounge. I know the Acura SLX was really an Isuzu.

[911GT2]

Ah, true. S2000 can hit 150mph, but that's a sportscar. The fact still remains that the stock 1994-97 Accord is speed limited to 112 mph.

And when i say Honda, i mean cars badged as Honda. Acura has a more sporting image, so to limit their cars to 112 mph would be just plain stupid, especially their type S.

But please, search for yourselves, the only Hondas you will see go over 112 mph (aside from the NSX and the S2000) are modified. See for yourself.

[ivymike1031]

That site showed 112 as the top speed, but didn't say why they picked that number.

S2000 is different? But I thought you said ALL hondas?

In regard to your statement about the rev limiter, consider the following:
The rev limiter in a 1997 civic is at 8000 rpm (unless my memory has failed). If the vehicle was in its top gear at 8000 rpm, and the rev limiter was limiting the vehicle speed to 112mph, then at 8000rpm in top gear the vehicle would be going 112. Using the same gear at 60mph would result in an engine speed of 4286rpm, which is WAY too high for highway cruise. For the rev limiter to restrict vehicle speed to 112 in top gear, the rev limiter would have to be set in the 'hood of 4800-5500rpm.

"The 2.0-liter engine of the Type-R is part of the new family of highly advanced DOHC i-VTEC engines from Honda featuring Variable Timing Control (VTC) as well as the highly renowned VTEC system. Its 200 PS (147 kW) at 7,400 rpm and torque of 196 Nm at 6,500 rpm enables the Type-R to reach 62 mph in just 6.8 seconds and go on to a top speed of 145 mph (233 km/h). "

112 is just an arbitrarily selected number, just like 276 hp. I can't peer into the minds of Japanese government officials to see why, so I can't explain why. And i did say all Hondas, and i was wrong. I'll freely admit that.

And i can't really explain the technicalities. Look at quoted top speeds, they'll agree. And keep in mind that i'm talking about North America in particular, and we don't get the type R here. Besides, the Type R is made in England isn't it? Which would mean it really wouldn't have to abide by regulations.

Badging makes no difference to Japanese regulations; there is no Acura in Japan.

a. Why are we talking about only North America if it's a Japanese regulation?

b. All Type R cars are made in Japan. The only notable (possible? I'm not sure...) exception is the Accord Euro R, which may be assembled in the U.K. The NSX-R, both Integra Type Rs and both Civic Type Rs were made in Japan, with their engines hand-assembled in the same Tochigi plant.

c. We (the U.S.) did get the ITR for 4 of its 5 years of production. We're expected to get both the new ITR and CTR sooner or later... Since the S and Si, respectively, are selling well.

[ivymike1031]

did you notice the Civic Si @ 133mph?
