ssl2k

Okay so im into a little debate about stupid ---- well anyways

im saying:

basicly:

the bigger the wheel/tire combo, the HIGHER top speed you would beable to get too....

example:

185/60/14s
zc tranny
si fd
7000rpm in 5th gear = 126.91mph

185/60/17s
zc tranny
si fd
7000rpm in 5th gear = 143.65mph

-------------------------

if you swap bigger wheels or bigger tires onto a car , your speedo will read slower than what your actual speed is going correct?...e.g. my buddy has 35s on his little truck and when you're going 55mph, if a cop gunned you, it would be like 67-68ish.

------------------------------------------

correct?

same RPM, same tranny, bigger tire = you are moving more ground, speed = distance / time . more distance = same time/(rpMs)...

-----------------

im not talking about acceleration, or anything like that. im speaking of the TOP speed that you'd beable to get to compaired at the same RPMs...

let me know if im right

smithSHO

In theory taller tires will give you a higher top end, that is, if the car has enough power to overcome wind and "----" (I had to do that because I want to fit in and be cool).

Yes the speedo will read slower than your actual speed in most cases if the drive gear runs off the diff.

ssl2k

power isn't an issue. 300whp we will say...

wind doesn't count in this problem

7000rpm in both situations

smithSHO

than yes you would have a higher top end. The taller tires give you a higher overall gear ratio.

Reddy

bigger tires give you more top end

Honda16hb

good to see you assimilating right in.

yes, bigger tire=higher speed at same rpm and speedo reading slower than actual speed.

ssl2k

yeah

this guy was aruging some fucked up points just a second and i'll psot the conversation

Honda16hb

oh no, a conversation, I'm way too lazy to read that crap.

ssl2k

you can tell my excitement to get my rods+pistons and hopefully i'll work soemthing so i get some of those conecept 17s...but anyways here is the convo

kyle just ------- read it okay? it is worth your time...if not i'll paypal you $.32 cents

therguy (12:022 AM): get some rota slips in 15"
ssl2k (12:022 AM): front 2
ssl2k (12:026 AM): naw
ssl2k (12:02:50 AM): i want 17s
ssl2k (12:03:02 AM): there is a kid runnign aroudn with a talon that has 16s
otherguy (12:03:04 AM): ehh thats just more wieght and power loss
ssl2k (12:03:08 AM): lol
ssl2k (12:03:18 AM): what is 4lbs when you're running 300whp?
otherguy (12:031 AM): 17s don't wiegh 4 lbs
ssl2k (12:039 AM): 4lbs difference between 15s
otherguy (12:033 AM): they weigh about 25 lbs a piece
ssl2k (12:037 AM): 24
ssl2k (12:03:52 AM): 15s are like 20
otherguy (12:04:16 AM): mine are stock ex alloys and they weigh in at 16.8 lbs
ssl2k (12:04:21 AM): oh well
ssl2k (12:04:25 AM): like i said, 300whp
ssl2k (12:045 AM): the bigger wheel will help offset my tight gear ratio
ssl2k (12:046 AM): so
otherguy (12:044 AM): ehh
otherguy (12:04:51 AM): not a fan of big wheels anymore
ssl2k (12:04:55 AM): yeah
otherguy (12:04:59 AM): had 17s and 18s and now back to 15s
ssl2k (12:05:07 AM): yah
ssl2k (12:06:23 AM): top speed will go from 120mph to 135mph
ssl2k (12:06:28 AM): by switching my wheels
ssl2k (12:066 AM): not to mention i'll have z rated tires
ssl2k (12:069 AM): which will be better than the ones i haveo n there right now
otherguy (12:076 AM): how will wheel switch make your top speed higher?
ssl2k (12:07:53 AM): bigger
ssl2k (12:08:11 AM): the larger the dia wheel, it switches the speed
ssl2k (12:08:18 AM): the tranny is still moving at the same speed
ssl2k (12:08:18 AM): but
ssl2k (12:08:22 AM): the tire is more
ssl2k (12:084 AM): the ratios are different
otherguy (12:089 AM): it slows down the speedometer
ssl2k (12:08:54 AM): yeah
ssl2k (12:09:04 AM): your actual speed is higher than the speedo
ssl2k (12:09:05 AM): like
ssl2k (12:09:14 AM): if you're going 25 mph on 14s,then you swap 17s
ssl2k (12:09:25 AM): when it reads 25mph on the speedo, you're acutally going like 30
otherguy (12:10:06 AM): doesn't mean your going faster it means your speedometer is reading faster
ssl2k (12:10:13 AM): but
ssl2k (12:10:23 AM): your tachomter is also in the same position
otherguy (12:10:26 AM): you have to calibrate your speedometer with your wheels size
ssl2k (12:11:11 AM): http://crx.honda-perf.org/math/
otherguy (12:11:20 AM): your tach is just a rev point not a speed sensor
ssl2k (12:11:25 AM): zc tranny
si diff
215/45/17
7000rpm 5th gear
ssl2k (12:11:28 AM): then
ssl2k (12:115 AM): change the 17 to 14
ssl2k (12:12:15 AM): your speedo and tach are pretty much locked together
ssl2k (12:12:24 AM): in a sense
ssl2k (12:129 AM): the tach reads the crank speed side of the tranny and the speedo reads the axle side
ssl2k (12:12:54 AM): clutch seperates them
ssl2k (12:13:11 AM): if you create a larger wheel that has more ground to put out per revolution
ssl2k (12:13:20 AM): your top speed will be different
otherguy (12:137 AM): it JUST adjusts your speedometer reading doesn't make you ANY faster
ssl2k (12:13:50 AM): uhm
ssl2k (12:13:59 AM): so you're saying that
ssl2k (12:14:00 AM): going
otherguy (12:14:00 AM): actually yourare going atthe same speed just your speedometer is reading off
ssl2k (12:14:04 AM): no
ssl2k (12:14:11 AM): im not even talking about that
ssl2k (12:14:13 AM): you're saying athat
otherguy (12:14:19 AM): my little brother is an ASE certified mechanic
ssl2k (12:14:25 AM): good for him
ssl2k (12:14:27 AM): but
ssl2k (12:146 AM): you're saying that redlining 7k in 5th gear, you're speed is going to be the same on 14s as it is 17s?
otherguy (12:15:13 AM): you will be at a slower speedon 17s
otherguy (12:15:14 AM): unless your speedometewr is recalibrasted
otherguy (12:15:23 AM): recalibrated*
ssl2k (12:150 AM): your actual speed will be faster tho
ssl2k (12:157 AM): im not talking about the speedo what so ever
ssl2k (12:15:50 AM): 7k in 5th gear on 14s is slower than 7k in 5th on 17s
otherguy (12:15:54 AM): no your overall speed is slower
ssl2k (12:16:53 AM): your crank is putting down the same amount of revlutions per minute, and you ratio is larger with the bigger wheel, you are moving more ground with the larger wheel at the same rpm
ssl2k (12:17:08 AM): more ground @ same rpm = faster
otherguy (12:17:18 AM): no your not moving more gorund with the larger wheel that isa MYTH
otherguy (12:175 AM): your revolutions per minute on your wheels slow due to larger diameter
otherguy (12:179 AM): not increase
otherguy (12:18:08 AM): you need to watch who youtake adviuce from because a lot of people are full of ----
ssl2k (12:18:14 AM): go do the math
otherguy (12:18:23 AM): I have done it already
otherguy (12:180 AM): Ihad 18" axis sevens
ssl2k (12:189 AM): think of it like this
ssl2k (12:187 AM): if you took 10 steps that were only 1foot apart
otherguy (12:18:52 AM): my speed was 5 mph slower than what my speedometer read
ssl2k (12:18:55 AM): compaired to 10 steps that were 2ft apart
ssl2k (12:19:18 AM): you've moved 10ft more with the bigger steps(bigger wheels)
ssl2k (12:19:24 AM): in the same amount of times
ssl2k (12:192 AM): speed is a distance covered in a period of time
ssl2k (12:19:59 AM): bigger wheels or bigger tires = you're going faster than your speedo says
ssl2k (12:20:06 AM): your top speed is higher with bigger wheels also
otherguy (12:20:18 AM): yes but bigger wheels DO NOT make you faster in ANY sense
ssl2k (12:200 AM): they give you a higher top end
ssl2k (12:209 AM): it is just like lengthing out a ------- tranny
otherguy (12:20:53 AM): your top speed is higher due to your speedometer being OFF
otherguy (12:20:53 AM): you car IS NOT going any faster than with the 14s on
ssl2k (12:21:03 AM): yeah okay...
ssl2k (12:21:14 AM): so you're saying that
ssl2k (12:213 AM): 7k in 5th is the same actual mph if you have 14s or 17s on there?
ssl2k (12:216 AM): that'd be like saying
ssl2k (12:22:11 AM): the ZC tranny will give you the same mph 7k in 5th as a HF tranny
otherguy (12:22:14 AM): accordingto your speedometer it is faster but in REALITY it is the same
ssl2k (12:22:20 AM): uhm
ssl2k (12:22:25 AM): im not speaking of the speedo at all
ssl2k (12:22:28 AM): i've said that like 5 times
ssl2k (12:223 AM): im speaking of the RPM
otherguy (12:226 AM): yeah the tranny has nothing todowith speed LOL
ssl2k (12:222 AM): ----
otherguy (12:228 AM): the gears are just setup different
ssl2k (12:23:11 AM): 7k in a HF is NOT the same as 7k rpm in a ZC tranny
otherguy (12:23:15 AM): if we were talkoing about an auto and a manual yeah the speed would differ but not 2 manual trannies
ssl2k (12:23:26 AM): yeah...almost
ssl2k (12:232 AM): im not talking about autos
ssl2k (12:233 AM): manuals
ssl2k (12:234 AM): if you take
ssl2k (12:24:05 AM): a HF tranny and put it in your car , and you get it up to 7k rpm, YOU WILL be at 190mph
otherguy (12:24:07 AM): 7K in 5th is &k in fifth no matter WHAT tranny youhave
ssl2k (12:241 AM): if you take a ZC tranny and get it to 7k RPM you will be at about 130mph
ssl2k (12:25:14 AM): what is your max speed in like 2nd gear of a dx tranny?
ssl2k (12:25:19 AM): like 50mph
ssl2k (12:25:22 AM): HF is like 90
ssl2k (12:250 AM): it is the exact same with wheels
otherguy (12:261 AM): no no no
otherguy (12:262 AM): in a dx tranny max speed in 2nd is 60 mph
ssl2k (12:27:11 AM): if you take 14" wheels and put them on the front of a car and put 17"s on the back, they are going to be travling at different RPMs...the 14"s will be going faster around than the 17s because they have more ground to make up compaired to a 17
otherguy (12:27:15 AM): but wheels DO NOT MAKE YOUR CAR FASTER
ssl2k (12:27:29 AM): THEY GIVE YOUR CAR A HIGHER TOP END
ssl2k (12:27:51 AM): that is a ------- true statement no matter how you look at it
otherguy (12:28:00 AM): NOPE WRONG
ssl2k (12:28:04 AM): the bigger the ------- wheel, the FASTER you will beable to go top end
ssl2k (12:28:23 AM): at a given RPM, the larger wheel will be moving you more than the smaller
otherguy (12:286 AM): on your speedometer ONLY notiin ACTUAL SPEED
otherguy (12:287 AM): switch wheels and go get a cop to clock you and see that I am right
ssl2k (12:28:52 AM): i've been pulled over in my buddys truck before
ssl2k (12:28:59 AM): he has ------- 35s on this little light truck
otherguy (12:29:07 AM): ehhh wrong again
otherguy (12:29:08 AM): the smaller wheel amakes more revolutions perminute due to smaller diameter
ssl2k (12:29:18 AM): when you are going what reads as "55" on the speedo you're acutally doing 67-68
otherguy (120:07 AM): no you will be doing 55 and get clocked at67-68
otherguy (120:11 AM): Ihave 2 speeding tickets due to my 18s
ssl2k (120:27 AM): the speedo will read "55" but the speed is 67
ssl2k (1200 AM): i just ------- said that
otherguy (1209 AM): no it is the other way around
ssl2k (1234 AM): zc tranny
si fd
185/60/14
7000rpm in 5th = 126.91 mph
ssl2k (124:03 AM): zc tranny
si fd
185/60/17
7000rpm in 5th = 143mph
ssl2k (124:09 AM): 143.65mph
ssl2k (124:12 AM): enough said
otherguy (1249 AM): 143 onthe speedometer butonthe Police clock it is still the 126 mph ENOUGH SAID
ssl2k (125:08 AM): yeah okay
otherguy (125:22 AM): I have been building cars since I was 16
otherguy (1252 AM): I started with a firebird and went tohondas
otherguy (1256 AM): wheel sizes are a too known subject for me
ssl2k (1261 AM): okay
otherguy (1262 AM): I drag at the tracks all the time and can tell youthat bigger wheels do notddo any higher speeds and if you EVER went to one you would see EVERYONE putting stock wheels back on for weight and speed gains
ssl2k (1262 AM): so that is why
ssl2k (1266 AM): im not talking about acceleration
ssl2k (126:52 AM): or time it takes for accerleation
otherguy (126:55 AM): no top speed
ssl2k (127:09 AM): the reason why they put the stock wheels on is becuase it is quicker to get there
ssl2k (127:14 AM): it doesn't give a higher top speed
otherguy (1277 AM): no it helps your top speed
otherguy (1275 AM): the 17s will SLOW you down
ssl2k (1289 AM): ---- that
ssl2k (1285 AM): okay
ssl2k (128:57 AM): i'll go get a cop
ssl2k (129:05 AM): and put some ------- 8" wheels on my car
ssl2k (129:16 AM): and go out and try to get 120mph with thos eon
ssl2k (129:16 AM): then
ssl2k (129:20 AM): i'll put some 18"s on
ssl2k (129:26 AM): and see which one gets there at what rpm
otherguy (120:29 AM): your tach reads rpm out ofyour enigne not your tranny
otherguy (1208 AM): that iswhy it is connected to the distributor
ssl2k (121:04 AM): same RPM, same tranny, bigger tire = you are moving more ground, speed = distance / time . more distance = same time/(rpMs)...
otherguy (122:06 AM): no your not jesus go to ITT or wyotech and try to feed them this bullshit they will tie yopu to a chair and show you the REAL explanation behind this
ssl2k (123:58 AM): mmk

Honda16hb

I almost made it to the end before I gave up concluding that you were talking to a moron. it's the same for auto and manual trannies, they both work on gear ratios, the only difference is how the power is transferred from engine to tranny and how the gear is selected, there are still gears in there with specific ratios. you gave him perfectly good explanations, he's just a moron. I would have you paypal me the .32 cents but then I'd end up paying paypal because of the fees, so ---- that.
