Top Speed

[4PASNU]

Where is the photo of the Celi owner who had a picture of nearly 160 indicated top speed. I have some idiots who have said it is impossible.
Thanx, Dan

[gts24]

um, this is maybe the one you are looking for.. not sure though?! tell those guys :fauku:

[4PASNU]

Thanx

[fastwhipyo]

not to be a lilbitch about the whole thing, but that could have easily been done with the car up on a lift with the tires off, or in the snow or something, and i was under the influence that the celica has a speed gov. on it with the stock ECU, i guess this could have been done with it off, but do you realize how much force the car would have to overcome to reach that speed? even if he had a 50 shot of NOS he would still have to hold the nos for an extremely long time which would be seriously bad for the engine. But it is possible and if this is for real then damn, thats nuts, you have to have HUGE balls to go that fast in a car with such little downforce, its gets all squirmy past like 120.

[4PASNU]

Wel just to let you know the Celi is drag limited so horsepower is what will slow you down. If you lower the car if will go faster and will be more stable.

[gts24]

That pic is legit, somebody on here took the pic while coming back from the track. ............ Somebody help us out, cuz I can't remember who/what/when/where..
I know it's east coast somewhere.

[larryd]

cliff (phewl) took a pic of his car doing 161 if I recall.. and its legit..the speedo does say 161 though Im sure its not accurate.. he was prolly doing morel ike 145ish..

[00ramair]

hmmm...
not a doubter...
but 300+hp F-bodies have a hard time going much above 160mph. and their drag coeffient isnt very bad (.33)

just a thought.

[00ramair]

oh and another thing, can someone please smack that kid for putting a carpet mat on his dash?

[fastwhipyo]

is that what that is...i thought it was some ugly ass dash kit, what the hell, who does that these days, honestly.

[97prizzzm]

well why can't he put that on his dash???? it is HIS car ya know

[Honda~Power!]

the celica is not speed governed? That is hard to believe.

161 is very impressive if that is true, much higher than i would think. If it is though, it kills the rsx's top spped of 145. Way to go guys, but i would never go that fast in a celica or rsx even if it could, the car is too light and has no downforce as someone else mentioned.

[4PASNU]

Sorry to break your heart but the Celi is drag limited. THe only thing that holds us back is horsepower.

[CeliMatz]

i have a '02 gt. there is no governor. lastnight it went 221 km/h (137 mph) redlined in top gear. this is for the gt, i don't know about the gts...

[CelicellGTS]

For the people running there cars at 160, you might want to check your tires to see what they are rated. If you have stock tires( mine are the 16" upgrade with yokohamas) then they are not rated to go above 133 i think. That is why the Celi has a speed limiter, its for the tires. You need Z rated tires to go 160 safely, or you might blow a tire going top speed. Just a thought.

[oodolbyoo]

Ive topped out at 138 in my GT

[TRD Liquid Silver]

if you look at the photo the dash it's pointed downward, weird huh? don't know about 153mph or 161, but i know there's some of us that got our cars to 144-146mph. I have a video of me doing 142mph that i sent to kleeftonsi and you literally see the backdrops wizzing by. the picture doesn't really show you anything as far as backdrops. i'm not sure but that car could be on a dyno.

the celica never had or does now have a rev limiter.

[BillWS6Formula]

As someone mentioned above, non-calibrated automotive speedo's are notoriously "optimistic" in the upper ranges. One of the ragazines did a test a couple years back whereby they took a cross section of many different cars and tested the car's top speed speedometer reading against a radar gun. The result? ALL the speedometers were reading high to the tune of 5 to 10%! One of the worst offenders? Ferrari! LOL The only other one I remember specifically was a cop issue Crown Vic which was dead on accurate - BUT it had a specially calibrated speedo, as required by law.

[97prizzzm]

the celica does have a speed govoner but it's not for the tires. almost all cars have them. they have to have them by law. the government sets it based on the vehcle, but can get rid of it :) and the cars that do not have them, like family cars, is because they top out before the limit anyway and cars such as the supra, viper, 911... don't have them because of the type of cars they are :/

[RACERGTS2000]

Speedos are pretty off at top speeds. I myself have went 150 racing a type R ( I really dont think that it was accurate). But the only way I can get my car to pull in 6th is by fuel cutting 5th. Because the way 6th is geared you fall out of cam if you shift at redline I dont plan on going that fast again though I scared the s**t out of myself because Celica gets very floaty at that speed. But regarding I was racing a typeR I wasnt about to give up.

[hedgehog]

What kind of animal is that on your dash?

Fu@kin scary!

[Ugly Pete]

my auto gts tops out at 142. i did it when i was stock like 3 times. havent tried since the cai got put in. it looked like it had potential to go alot faster cause it was only at 5000 rpm or around there and wouldnt go higher

[racinjason]

I don't know if some of these people just aren't reading the prior posts in this thread or what, but the Celica does NOT have a speed limiter. If it did we wouldn't be doing 145+. I redlined in 5th racing a 911 Carrera 4 and glanced down to to see about 144-145 or so. So I don't think the speedo is too far off. Maybe a few percent.

6th gear tops out at a speed limited 175 but most don't have the horsepower to reach that yet. And you better check your tire ratings before you venture over 125. I had my car just lowered with TRD springs and stock struts when I ran that fast and it was 100% stable. I was very impressed. I'm sure it would really be even nicer now with the Tiens.

[2001redgts]

JEZUZ people, the celica is NOT speed goverend nor does it have a speed limiter. It DOES NOT have any kind of chip to limit your speed. Hopefully this will clear it up for some of you.

[j28s]

No, it is not legit! Come on guys, let's get back to reality! Someone go do some homework! Let's think of HP along with torque. Now let's think of drag coefficient. Now let's think of the transmission and FD.

[MaddMatt]

I have no doubt that this photo is real and it really indicates 160+ mph.

But:

The REAL top speed of a car is determined like this:
The average of a 2 way pass with a calibrated 5th wheel attached to the car. This takes out any effects of wind, road slope, and most importantly speedo inaccuracies. This is how all the serious car magazines determine top speeds of cars. Not with a one-way pass down hill with a tailwind.

Car&Driver, Dec 99, lists the Celica GTS with a top speed of 129 mph. THAT, I believe.

[autxr]

Boy o boy, all you haters of the honda/acura/nissan type...:)

Anyhow, based on the "numbers" (gear ratios and tire size) the Celica will do 134 mph in 5th gear at 7800 rpm.

This is in pretty close agreement with the 129mph that C&D reports. One thing the car magazines seem to be good at is shifting AT redline.

The Celica will let you rev to about 8300 rpm (the 2000 and 2001 models), and at 8300 rpm in 5th gear you are looking at a calculated 143 mph (within error of what many folks ahve reported in their GTS's).

Unfortunately, 5th gear is it for a stock Celica, shifting to 6th reduces the power to the wheels enough that you start to slow down.

The theoretical top speed in 6th gear at 8300 rpm is 181 mph.

So, the question is, how much power do you need to make it accelerate in 6th gear...

At the torque peak (6800 rpm) you have a calculated 93 ft-lbs at the wheels (based on my dyno results), in 6th that value drops to 73 ft-lbs.

An 8300 rpm shift in 5th will land you at about 6400 rpm in 6th, with wheel torque dropping from 79 ft-lbs to 70 ft-lbs.

(Results all based on a 4th gear dyno run in my car, 118 ft-lbs to the wheels at 6800 rpm - that is the peak).

I am pretty skeptical about the picture as well, I suspect it was done on a dyno or with the wheels in the air, but the car most certainly can top out 5th gear given the room.

Also, I suspect the actual top speed can be accurately determined with a radar/laser gun (that is how they do it at the salt flats isn't it), or a stop watch and a measured distance. The 5th wheel will add drag and not give a true top speed.

[MaddMatt]

How's it going Scott? Man, they'll let anyone moderate around here, huh ;)

Boy o boy, all you haters of the honda/acura/nissan type...Actually like the GT-S very much thank you. Sure wished I fit in one with a helmet...

I suspect it was done on a dyno or with the wheels in the air, but the car most certainly can top out 5th gear given the room.

So, the GT-Ss top speed is acieved in 5th gear?

I suspect it was done on a dyno or with the wheels in the air,

Me too.

[autxr]

Sure wished I fit in one with a helmet...

Me too!

So, the GT-Ss top speed is achieved in 5th gear?

That's my understanding.

Man, they'll let anyone moderate around here, huh

Yes they will!

this photo was taken by Cliffs gf on the way home from the first celica track event a willow springs. I know excactly where that shot was taken, because cliff told me himself. It was taken going north bound on Interstate 5, on his way back home to San Francisco. what many people don't know is the excact spot that was taken. it was going down from a summit pass with approx 5% down grade!!!!! So yes he is going that fast. As AutoX mentioned just do the math on the gear ratio and you will find his excact speed on 6th gear

[GTS LAID]

i dont remember but i think larry told me cliff sold the car.. is that true... ever since pdc went offline

[Maelfyn]

Gimme 10 minutes, a screwdriver, a digital camera, and some clear adhesive, and I'll post a picture of a GT burying the needle! Wowow..

[MaddMatt]

it was going down from a summit pass with approx 5% down grade!!!!!

So basically he's cheating :). If my calculations are right, my SE-R should be able to top out at ~162mph if I did the same thing.

[O2BQIK]

What's the Celica GTS's CD? I don't know the number but it doesn't look like it'd be that good...looks like it'd generate a lot of lift too. I believe 129, maybe a touch more for a modified car, but 160 is stretching it. Like 00ramair said, us f-bodies have 300-ish at the wheels when stock, and top out right around 160, with a CD that's not bad (not supercar, but i would imagine better than the Celica's). Hey it might've happened...but also might've been downhill with a tailwind like stated ;) And also as stated, even if the speedo read 160, it was probably more like 145...16 mph higher than the magazine that someone quoted. Some mods + downhill + tailwind...I'd say it might not be a fake picture :)

thats if you do it.

the celicas coefficient drag is 0.32 same as the nsx. ever wonder why the nsx has the same top speed as some more powerfull sport cars out there?

[MaddMatt]

thats if you do it.

What if I shoved my Sentra out of an airplane. I bet I could get up to 400, maybe 500 mph! I'd have the fasted all-motor import!!!
