I have been 142mph before I ran out of room

I had an S for four years. Great car, but you must have been going downhill with a tailwind.

TSXual

'07 six speed just a short ram and dc header 138mph after shifting into 6th does not accelerate after... has anyone been able to hit ivtec in 6th...?

TommySalami

I thought your top speed would be in 5th. I hit 130 in 4th (at) and had plenty of room to go in that gear

disc0rd

170 km/h with plenty room to push more

My fastest speed was 123 mph (in both of my accords)...I was going up on a slight incline, and I guess I was experiencing too much wind drag since I couldn't get my car to get past that speed. My TSX should be able to go faster than that, but I'm not crazy anymore

i did 125mph @ old airport runway strip in bklyn.. pavement wasnt great so i slowed down.. brother did 139mph with a friend, i and luggage in the car on the 407etr in ontario. vsa off but ac on.. was in 4th..car is stock, performance wise

Tsx6363

HA try 55 here in NYC

timd38

Ya right, 139 in stock TSX in 4th gear. The math doesn't work.

TommySalami

AT maybe? I know you could do that in 4th with the AT

Mokos23

Fastest speeds I've gone in cars I've driven/owned

88 Accord 105 mph because it started shaking like crazy

99 Accord 118 mph

99 ML 320 110 mph

04 TSX 117 mph

04 G35 sedan 126 mph

It's like the guy that told me he eats Corvettes with his Mini, when I showed up at a Mini event at race track with my Corvette, it was a humbling experience, for him. My Corvette was in August GM High Tech Performance magazine for details.

TommySalami

What? What does that have to do with anything I said?

rex.

i kid you not.. 4th gear in the 5AT, speedometer showed 144 but im going off the 139 the garmin gps showed..

TommySalami

I bet the top speed for the 5AT will be in 4th gear anyways because 5th gear is so much more for cruising and gas mileage

timd38

OK, the TSX weighs as much as a Corvette and has 1/2 the horsepower, but is just as fast in 4th gear. Does that make sense to you? The TSX doesn't have enough horsepower to overcome the drag. Sure you weren't looking at kilometers?

TSXRudebwoy

I did 142 mph bone stock 07MT dont think anyone can go over that stock. I did this with almost no variables so it would probably be pretty hard to do it on the road.

jlukja

Weight is a major factor in acceleration, but not in top speed. At top speeds its a question of gearing, horsepower, and the coefficient of drag. What's the drag coefficient of the TSX and the 'Vette?

Deity711

Honestly, I think the fastest I've taken the TSX was only 75 mph.

fred_mumble

Right around 100 is the top end I've hit.

I had my stock '94 Integra GSR to just over 140 a couple of times and it only had 170hp! The top end was only supposed to be 130 - I wasn't going downhill so maybe my speedo was way off at the top end.

Tangoman

The TSX has a better CD than almost every car... .27
This is better than even a Lamborghini Gallardo, or even a corvette.

CD is a big deal, but it doesn't matter if the TSX has half the horsepower, that doesn't mean it goes twice the speed, its a exponential relationship between the two.

For example, in order for a Corvette to get to 250 mph, it would need another 500 horsepower, assuming the CD of the Corvette is unaltered, DRAG is almost always the limiting factor in top speed, besides those 155 mph limited German cars (Mercedes, Audi, etc).

If you derive the equation for the top speed of a car, using all the forces the car experiences, including the normal forces and the friction coefficient of tire vs. road (about .7 under acceleration), you will see the drag coefficient comes into play more and more.

Force due to drag=(1/2)(density of air)(velocity)^2(Aerodynamics CD)(Frontal area of the car)

With objects moving through fluids (air) this is always the limiting factor, for cars, drag is the most important thing.

Another example just to finish it off, the Subaru STI even with 300 horsepower, has a pretty bad CD (.43) which means, even though it has all that power, it only maxes out at 143 miles per hour (which is essentially the same top speed as the TSX).

Roffles

On my last road trip, with a huge stretch of smooth abandoned road on the I-5 in California, I took my '07 AT to 120mph in 4th gear very easily. I was still accelerating at that point, but backed off because the scenery was moving past me too fast and It felt dangerous and uncomfortable. I have the Potenza 960AS with a ZR speed rating and the A-spec drop...these variables probably help high speed acceleration and stability a little bit over stock.

lvcurvs

Only hit 100 and that was by accident. Went to pass a tractor trailer on a down hill slope. Ha, looked down after i had passed him and was like woah! Didn't even feel like it.

925tsx

fastest ive ever hit in the tsx was just a tad under 150. (downhill)
ive done 140 in it at least a dozen times.

04/ auto.

maybe thats why my engine blew up...lol

here is a pic of 140 taken with cellphone.

Wednesday morning I was on my way to work . It usually takes me about 25 min or less. I love my morning drive to work especially when it is a cool crisp autumn morning as with the Injen cai runs great. Well it was 7 am and 95 in Delaware has a little construction going northbound into Wilmington. I run into the normal crowd as people switch lanes and jockey for position. Well I find myself next to an Audi A4 type s body kit a little work done I can hear the intake but what really caught my attention was he had the square exhaust which I thought was really cool. So he is looking at me and vice versa now I know he can hear my exhaust as I can hear his, so we continue to taunt each until we pass the construction and I know it is going to be on as soon as we break free of the traffic. Well Im in 2nd when we break free and I can hear his turbo wine. Then he looks over and gives me a nood and we just drop the hammer BAM the vtec kicks in. Anyone with an Injen intake can tell you it is loud as hell. He pulls ahead slightly half a car length at the most. He and I have a straight shot atleast a mile or 2. I mean we are rollin I stuck with him until I hit 156mph and that audi started to pull a little more but It was fun as hell. I made It to work in 7minutes

cestmoi

Nice story Sean, but next time, a heads up when you decide to do that again so I won't be anywhere close to Delaware! Geez.

TommySalami

You sure about that 156 mph?

Maesm81

Got the ol' TSX up to 120 on the way to Vegas last weekend. On the 30 mile stretch of fwy from the california nevada state line to Vegas. I was following a 4cyl. Altima and a Caddi STS. The TSX felt great at those speeds. No complaints. The Altima was having trouble keeping up, that STS with the northstar was impressive. It had no problem accelerating away from us at those speeds. The ol' lady was pissed but I was having fun.

davidspalding

Please, guys, no more cellphone pics while you're doing that speed. ¿Both hands on the wheel, por favor?

TommySalami

I was thinking, who the hell takes a picture with a phone while they're goin that fast!? That's crazy!

sean522

The only picture I took was at 142mph. It is my belief that if anything happens at the speede 1 or 2 hands aint gonna make a difference. 1 false move or bump or blowout 2 hands aint gonna help you

wackura

Wow, that's so incredibly wrong. Anyway, it was nice knowing you. Wish I'd known you better.

alucardx

I'm in DE too. where do you work at? I work at AZ on 202 but I take the back roads to and from work since i'm in Pike Creek. I95 is a nightmare during rush hour as you're aware.

I like the straight away on I95-N after the 495 split off, and after the little cop hiding spot in the split in the median. you can hit some good speeds on that route that goes past the baseball field and Iron Hill area.

I have a NHP '06 5AT no-mods.

davidspalding

It might've been a passenger taking the shot, and that occurred to me, but I couldn't resist the snipe at someone who has a picture to prove it. Nothing personal of course.

I'll go take my own tonight by doing the diagnostic thing. I hate being left out.

TommySalami

hey you all think a drop would lower the top speed/make it easier to reach? Theoretically it should help a good amount

tsx4lyfe

i have done 120 or more i couldnt remember i wasnt gonna stare at the speedometer then crash!!! but it still was pushin pretty sure

zguy95135

Well me and my friend got it up to 135 (and climbing) out past Paso Robles on the 101 at like 2am, clear straight road with no one else around. Never again but it could have gone faster, it was about 6800ish rpm in 6th gear.

gamblez

well on the way home from El Centro going to San Diego theres long straights...

with my mods
pulleys
I/H/E

i went all the way to 135-136 car felt like it can keep going im guessing i can go to 150

Saeyon

fastest i've done is about 90 something

JdmStyle

Have since tested with full GPS on board.. and have the topspeed saved.. 139 MPH.. and I have gone faster then that.. but had Microsoft Streets and trips which doesn't save speeds. was showing 150 on that..
