What's the fastest/top speed you ever driven on your tsx?
I have tried just a few hours ago on the way home: 135 mph @ over 5k rpm
(135 mph = 217.26144 kph)


is there a limiter chip?

that's with an automatic, right ?
A 6-spd should hit max speed in fifth.

Here are speed calculations for my 2006 MT. The gear ratios
are from the 2006 TSX sales literature. Note that the published
ratios are to only three significant figures so accuracy
could be improved by counting gear teeth. But since my tire
measurement is also to three significant figures the calculations
are pretty close. Also note that the speeds are actual, not
indicated - your speedometer and tachometer are not that accurate.
I've separated the three columns with semi-colons because the forum
absorbs spaces and tabs.

gear;gear ratio;speed in mph at 7100 rpm with a 78.1" circumference tire

1;3.27;33.7
2;1.88;56.4
3;1.36;81.1
4;1.03;107
5;0.83;133
6;0.66;167

diff ratio = 4.76

no, its a 6speed, i punched it all the way on the 6th gear trying to get the highest speed possible
maybe the speed isn't correct as you said the speedometer is off. damn, i should've taken a pic. oh well next time! lol

I'm pretty sure you won't hit max in fifth. Sixth won't get you much acceleration though so don't expect much more from it unless you have a 10 mile stretch of road you can drive on. I've made it up to about 130 before and she still felt secure, but ran out of straight road so had to slow down for the turns.

ck123

what are you trying to accomplish? never will you ever need to find out the max speed of a tsx unless its made for the track

valeratj

5k RPM VTEC engagement point would definitely be helpful here...

I'm just trying to see how fast anyone went in their tsx. "What's the fastest/top speed you ever driven on your tsx?"

I revved it up on all 6 gears... since it was a open highway. I was going at 135mph for about 2 minutes straight and then let off since i didn't see the needle on the mph wasn't going any higher.
If you've been on 249 in houston late at night, you'll know how open it is. lol

anybody ever hit v-tech in 6th gear without mods?

Mokos23

the speed limiter i read somewhere back was 142 mph.

TS_eXpeed

I've heard the limit is 145.

Personally my top speed has been between 115-120. Only did that once.
I've done right around 100-105 just a few times.

deadlyklappy12887

i got an 05' AT..when it was completely stock i got it up to 130 i still have the video on my phone..but then i got scared shitless b/c a nice gust of wind could really put a damper on your party plans..i live in northeast ohio, mind you, the weather is rediculous here it can change on a dime

PrecyseStylez

3 times i've went to the limiter at 142mph in 5th and 6th gear. Since Kpro, i havent tried it again.. i dont think its gonna be any different but it may.

robles325

i have a question about the limiter.. if the limiter is set at 142. why post the speedometer up to 160? maybe be a stupid question. but i would like to know. thanks

Itchytoe

It looks nice. Max speed limit in the US is under 100, so why have speedometers go above 100? Same reason, it looks nice.

robles325

i may be wrong but i heard in some cars there is a chip that sets how fast it can go? is this true? and if so.. how can you disable it?

SoCaliTrojan

The limiter is set to prevent damage. All engineered machines have limits, and limits are set to prevent it from exceeding their limits. With that said, the car may have some more juice in it.

There might be other reasons, such as maybe you're at the top of a steep mountain with a trunk full of bar bells. In that case, gravity might help pull your car down faster when you're already at the limit. Or perhaps they think you might want to put on 13-inch rims so that the wheels are spinning faster at each rpm. Or maybe it's aesthetics and they wanted the car to look like it can go faster than it really can. Or maybe they use the speedometer design on multiple models, and the other models can reach that speed? Or maybe the limiter was set low enough that the oem tires won't blow when you try to hit the limiter. The list can go on and on...

Yes. Remove your car's ECU to remove the limiter. Your engine won't run, but it won't be limited anymore. lol

Chances are that you won't improve your car's performance enough to warrant it going beyond factory speeds. If you do need to go over 142-145 miles per hour, you're utilizing the wrong type of vehicle (go get a ferrari or something).

last week i took the TSX to the highest i've gone in it, 112 mph because i had a lot of open road. i really hate the OEM rotors in this car! They have to be the worst because when i braked the steering wheel vibrated so violently i felt like i was going to loose control of the steering wheel. I have had them fixed already 2 times before by Acura service. i am thinking of going aftermarket now.

I had a hot flash; that was pretty quick. TSX? 110. ^I, too, ran out of open road.

litesout

I've gotten up just over 90 before passing a semi on a 2 lane road. There was nobody in sight, but once I passed the nose of it, I felt no need to go any faster. That was my first experience with VTec too. Good times.

CarbonGray Earl

120 or 130 in mine, very briefly. I can't remember the exact speed. All I remember is that it was quite noisy and the A-spec suspension has really short travel. Doesn't absorb inconsistencies in the road very well at those speeds.

Still, the engine was blender smooth.

RogerPodacter

I had my tsx up to 139mph in nevada outside of vegas. Just to see how fast it could go.

What is an open road? Do you not have deer, possums, and armadillos in Texas? At high speed at night, you cannot see where you are going since you are outrunning your highlights. In other words, you could not stop before you hit the barrier if there was an unlit barrier in front of you.

Itchytoe

Actually, no there are no deer possums or armadillos in Houston. If 249 is the one I'm thinking of, there's normally nothing on it at night, cept other people playing.

lightjak_tsx

..... 80 is my topspeed hehehehe...

zguy95135

An indicated 135, I was in sixth gear and it was still pulling (albeit slowly). It started to feel floaty so I backed off. I wouldn't recommend doing that but it was at 3am in the middle of nowhere.

PrecyseStylez

Hitting 142mph is so easy with my tune.. I've tried it once since K-Pro and its alot easier to hit but there is still a limiter there.

Wow. It is hard to imagine a road about 8 miles from a major airport in an area with the population density of Houston being free of traffic. You can't find anything like that around Atlanta. And, in western North Carolina, deer are always a looming threat.
