Top Speed for Each Gear

[4PASNU]

I also need this file on Top Speed in each gear. Mathmatical

[larryd]

hmm.. im shooting off top of my head if i remember corectly

1st - 28
2nd - 62
3rd - 88
4th - 113
5th - 160+
6th - never tried it

[oldster]

Straight from the horse's mouth.

[4PASNU]

I now that and have that one. Someone made a chart awhile ago on top speed with your gearing. It was a mathmatical calculation

[scapamouche]

With stock gearing and tires (205/50/16), the Celica won't make 160 in 5th gear. My record is 137 at about 8000 rpm in 5th. That makes for about 143 before the fual cutout at 8300 rpm.

I didn't try going to 6th, but on its own, the car stalls out at about 110 in 6th. Maybe with the higher rpms shifting to 6th from 140mph, it'll be better, but I don't see the car pulling in 6th from that high. Not without MAJOR power mods, anyway.

[PorkchopSpecblue GT-S]

Here are speeds according to car test2000
(also assuming you rev to 8200rpm)

1st...........41
2nd..........64
3rd...........89
4th...........113
5th...........145
6th...........(doesn't say but if your car had enough power probably reach a top speed in the 170's)

[cilvrwing38]

wut!!!!!!!!!!!!!damn!!!!!!!i went racing 2day thinking that i can go 90mph on 2nd gear.....lol

[00ramair]

1st..... 49 -MPH
2nd.... 73 -MPH
3rd..... 100 -MPH
4th..... 130 -MPH
5th..... 176 -MPH
6th..... 260 -MPH

oh wait, that's an Fbody ;)

[cjbaldw]

Here's some links that do the calcs for you:

http://www.angelfire.com/fl/procrastination/rear.html

I posted a link a while back with the actual formulas to calculate all this manually as well, I'll try and pull it up and edit this post if I find it...

[t2000gts]

6-speed:

1st gear (3.166:1)

5000rpm -> 24mph
6000rpm -> 29mph
8000rpm -> 39mph
8300rpm -> 41mph
9000rpm -> 44mph

2nd gear (2.050:1)

6000rpm -> 46mph
8000rpm -> 61mph
8300rpm -> 64mph
9000rpm -> 69mph

3rd gear (1.481:1)

6000rpm -> 64mph
8000rpm -> 85mph
8300rpm -> 88mph
9000rpm -> 96mph

4th gear (1.166:1)

6000rpm -> 81mph
8000rpm -> 108mph
8300rpm -> 112mph
9000rpm -> 122mph

5th gear (0.916:1)

6000rpm -> 103mph
8000rpm -> 138mph
8300rpm -> 143mph
9000rpm -> 155mph

6th gear (0.725:1)

6000rpm -> 130mph
8000rpm -> 174mph
8300rpm -> 181mph
9000rpm -> 196mph

REVERSE (3.250:1)

6000rpm -> 29mph
8000rpm -> 38mph
8300rpm -> 40mph
9000rpm -> 43mph

it varies by a few mph cuz of drag and other factors in real life.

[speedfreek876]

what about us 5-speeds??

[oldster]

t2000GTS, where did you get those numbers. I compared those to the Toyota numbers and the difference between the two increases as speed does. Speedometer versus calculated perhaps?

[t2000gts]

mine are calculated.

they're off by a little. the most they're off by is 2-3mph. the top speed in 6th is 178mph, calculated, AND some guy on the dyno did it.

EDIT: interestingly enough, a 'good' 1->2 shift on a 6-speed would be around 6000-6100rpm, right? it's hard to land cuz that rpm is about 4-5mph faster than redline in first. so that's why you gotta shift so quickly to cover that 4-5mph 'gap'.

the auto GTS has a gap of about 7-8mph between shifts that it covers. with an exhaust it lands at 5000rpm in 2nd (after shifting out of 1st at about 45-46mph). which is around 52mph. usually though, it lands at 4900 to just under 5000. but with the exhaust, it lands at 5000.

so does this mean it actually does shift hard enough? you can't really feel it shift hard obviously cuz it's an auto, but that's quite a gap it covers.

Thanks, I would have thought your numbers were actual readings. Thought that because the ratio between your numbers and Toyota's increases as the MPH goes up. I am assuming they did theirs at red line or 7800 so I looked at your 8000 numbers.

The differences were:

1st - 2MPH
2nd - 3MPH
3rd - 5MPH
4th - 7MPH
5th - 9MPH

Have no idea what this means but thought it was an interesting anomoly. Hmmm maybe Toyota did real world and we're looking at the effects of drag at speed?

[scapamouche]

Something to remember about automatics: Under load, they don't turn at a 1:1 ratio. What I mean is, that the engine side turns FASTER that the tranny side because of how the torque convertor works. It NEEDs a difference in speed to transmit power. Therefore, when you shift and the car SEEMs to step over that 45mph rpms to 52 mph rpms gap, what's really happening is that the converter is allowing the engine to spin faster to transmit torque.

Once you are at a stable speed, modern automatics lock the converter. The input is splined with the output so they turn together. Hence the lack of slip at constant speed. Makes less heat, allows the tranny to run cooler and last MUCH longer.

Do the wheels start turning if you rev past about 2200 rpm when at a stop, in 1st gear? Regardless of how hard you hold the brakes? That's called the Stall Speed of the converter. The same characteristic of the torque converter causes both stall speed and the slippage seen under acceleration.

I got really deep into that automatic gobbledegook when I had my old Nova. Tuning the tranny for what you want is largely about selecting the correct torque converter- high stall speed allows for a more peaky high rpm motor to work, but is bad on the street- tends to overheat. A low stall allows street driving, but needs a wider powerband to be fast. I went with a moderately high stall (3500rpm) and spent every day on the street wishing the converter locked up. I had serious tranny overheating issues. Especially in VA in the summer.

[oldster]

Thanks for the dissertation bubblehead but we were discussing 6 speeds. Go Navy.

[scapamouche]

Look two posts above mine, there, bub.

t2000gts seemed a bit confused.

[t2000gts]

hahaha, oldster: yeah i think the difference is because of the gearing. it's the 7800-8300rpm difference, but the higher up the gears you go, the more mph per rpm each gear packs. or something.

scapamouche: yeah, i was figuring it was torque converter slip...because zooq got a 3100rpm stall on his auto GTS (stock is 2000rpm stall, blah) and he drops to 5100rpm shifts easy now. before it was about 4900. (unless you have an exhaust, add a hundred rpm). and valve body recalibrations/shift kits just reduce slip right? so they make the tranny last longer AND shift quicker. i wanna get one. BTW, did you have an ATF cooler on your car? if not, it probably would've helped a little ;)

[larryd]

hmm, I actually told you what the car really does do in each gear.. i have redlined each gear :)

hmm...what RPM were you at to hit 160+ in 5th?

[larryd]

about 8200..

[oldster]

That shows a dramatic difference from the calculated and the Toyota numbers, speedo?

[larryd]

im sure the speedo is inaccurate.. im sure it was prolly closer to 145ish.. I also had 18s on with 215/35s

[scapamouche]

Oldster: What platform? Not the arch enemy P-3, I hope!

Not that they can find us unless we TELL them exeactly where we are!! :)

Aviator or Aircrew?

T2000gts: I did have an auxiliary cooler, and it was the only thing saving the tranny. It really didn't like that hot weather. I don't think the 500hp going through it really helped either, though.

Shift kits will make the tranny internals tighter, and shift faster, but it won't do ANYTHING for the torque converter. To change the slip there, you need to replace it, like zooq must have with his 3100 stall.

Last year's unpleasantness in China hit pretty close to home then, didn't it?

Greenville's incident did the same for me.

Yes it did, glad everyone came home safe at least.

Ok where are you getting this?? You thank a celica is going to hit 196 mph?? Thats Viper and most exotics territory..I think you need to put the crake down buddy

[4PASNU]

No one said that the Celica will do196 mph but with more horsepower it will. There is a program calculates speeds for gearing. A Camaro or Firebird even a Viper will have a higher top speed with more horsepower. The Celica is nothing different. Sorry to bust your bubble but your V8 will on any day get passed by a lower displacement, with ease. HAHA

Ok do you know anything about cars??? You know how much its going to take to get a celica to do damn near what hes claming? You will need at least 6 to 700hp, something like 30$k later maybe..I'm not claiming anything by my v8, so sorry to bust your bubble, bring on any lower displacement car that cost less that 50 grand and pass me at top speed of 162mph stock, whoopdedo

It may be helpful if you would read and comprehend before responding. The numbers given where calculated on gear ratio and RPM, nothing more-nothing less. You obviously would have to have the horsepower to reach the calculated speeds, noone is saying the Celica can do them.

[scapamouche]

And here I thought we were trying to get less offensive here at NC.org. I guess everyone hasn't listened. Pity.

Wheels and tires make a difference too. As does speedo error (at least for what you see in the car.)

[4PASNU]

Well don't mean to burst your bubble. Go pick the latest issue of Sport Compact Car. 184 mph Civic will be more then enough to EAT your F-Body. Come here to Knoxville, TN and I will be more then happy to introduce you to a 2.0 ALL-TRAC 485hp$18,000 a$#whoppin.

[AllV8]

Ok NPASNU or what ever your name is, does this "485" horsepower civic come with air, stereo, powerlocks and windows..you know all the goodies or is it made for drag? Hey I'm all up for REAL performance vs wannbies. Hell I'll be more than happy to run him (in Texas)..will I get beat, yeah probably, bad probably not..Remember I putting close to 400hp with less than 700$ and let me ad some more stuff and I will have around 5 to 600hp, but that cost money, and again let him do his crazy 184 run on a highway...that way I can laugh at his sorry a$$ when the cops are talking his a$$ to jail. Some off you guys need to get a clue about what your talking about before you make claimes like these

[racinjason]

Come on guys. Lets not turn an inocent post into a pissing contest. "My cars got more than yours". "I can do it with less money", "My insurance is cheaper", "My car looks, handles, drives, smells, picks up more women than yours". etc. etc. etc.

This should be grade school play ground talk. Not sucessful enthusiasts talk.

Does this all really matter to the owner of any said car what someone else can do better, cheaper, etc. NO.

I get the Sh!Ts of seeing this all the time. Hell my friends wife acts like this to my wife and I want to slap her and send her in for a time out with my son.

On the real topic. I ran to 143-145 mph in 5th gear. She was redlinin for sure. I was too scared to really pay attention to the speedo much while racing.

AllV8: I think he was saying he spent $18000 total on the car and the money put into it. The All-trac 2.0 liter motor is capable of over 1000 horsepower and almost as much torque in full race trim. And that's actually destroked to 1.9 liters.

[4PASNU]

You are right RJ. Millens Pikes Peak Tacoma bore out his 3sgte to 2.1 and it puts over 1100 at the wheels. It ran in the high eights on ralley tires and was going down the 1/4 sideways and spinning.

I to was at fuel cut in fifth and went to sixth and kept pulling but I was out of road. I wonder what Bryan H would have done in the quarter if he had lightweight flywheel, clutch. I think he would have been in the 12's. We will see 12 sec Celica's buy the end of the year.

V8 dudet, go pick up the issue of Sport Compact Car. I would put all my money on that Civic. On a side note I won a contest for and had a choose of $25,000 or TransAM. Well I took the car and traded it in for my newest Honda. I will take an import over domwstic nayday of the week.

[Jesse IL]

If you want to figure it out mathematically, you will need engine rpm, gear ratio, final drive ratio, and revolutions per mile (a tire rating you can get from manufacturers). For the stock tires this figure is 859 rev/mi

Easiest way is figure out axle rph (as in hour)

Axle rpm = engine rpm / gear ratio / final drive ratio

Axle rph = axle rpm x 60

Speed = axle rph / tire revolutions per mile


The only problem is figuring out tire diameter. Manufacturers give several ratings, revolutions per mile, static loaded radius, and overall tire diameter. I have a feeling that at speed, you will see a number closer to the overall tire diameter. In that case here is how the calculation is different

Speed = (axle rph x overall diameter x Pi) / 63360

For second gear @ 8200 rpm, you get 61.7 mph using the revolutions per mile figure and 63.3 mph using the overall diameter figure

For the stock Yokohamas, the values are 24.1" overall diameter, 11.2" static loaded radius, 859 rev/mile
