Any way getting past the speed limiter on the XB? Mine will not accel past 110 mph. even though not close to the rev. limit.

You're driving a box with only 107 hp. That's your speed limiter right there.

You're driving a box with only 107 hp. That's your speed limiter right there. :rofl: i swear some people have the craziest ideas.

there is no governor on the scions.

A friend said no scion xb could go past 110 without alt'n the computer settings?? Is this true?

i get past 110 just fine so i dont think there is a limiter on there unless you tryin to go up a hill..... haha try goin down hill or something it might help you out :P but yea like hot box said there isnt a limiter on Scions aside from da hp haha

In a recent comparison test, Car and Driver states that the Scion xB has a top speed of 109mph, governor limited.

EDIT: Sorry, misquoted the article from memory. The real number, according to the magazine, is 111mph -- drag limited, not governor. See page 91 of the February issue of Car and Driver to check my source.

well there isn't
i've gone just over 125mph so i'd say the 109 is not true.

getting the car to 125 under its own power? at the very least the tc is limited, governor and rev limiter

almost all cars have a rev limiter.

i don't believe the tc has a governor but I may be wrong.

and yes 125 under it's own power. on a flat road.

I think I'll give the dealership garage a call and ask a mech. about it. I'll let you know what I find out.

Sorry for the misquote I posted above, folks. The article states 111mph top speed, drag limited. Theoretically, this means that if the engince could produce more power, the car could go faster, since there was room before the redline when the speed maxed out.

Out of curiosity, what power mods do you have that allowed you to hit 125mph?

I think I'll give the dealership garage a call and ask a mech. about it. I'll let you know what I find out.

There's no limiter, we already told you that.

i hit 120 then backed off... i do have to say it takes a while but it will get there

yea i hit 120 but i didnt really back off cuzz i was racing an civic ex at da time but it does take some time to get up there

it takes you guys awhile to get to 120? that sucks.

---that fast in a 'toaster'.Don't you care about me? I am out there too you know.

Just got off the phone with Service Dept. at Central Florida Toyota. They said that the Xb comes with the computer set to not let the vehicle exceed 110 mph from factory. This can be changed by someone at any aftermarker shop that has knowledge on how to access the settings. The dealership can change them, but will not alter this for you for obvious reasons. Then are allowed to set it lower though.

Its not a governer, its a computer setting and as you reach 110 mph, your cars computer will simply restrick the flow of fuel so as not to exceed the set speed. They said if you have someone who has an XB that is going 124 mph, someone has altered the settings.

Fuel cut, damn that sucks.
Still running the 19"s, they are over diameter, so you are going faster than the Speedo reads.

ok, i have hit 125 on 19"s on a flat road during mid day. i clocked it with my GPS, and according to my GPS, i was doing a true 125mph. Tires were installed at dealer before i took delivery so they did the adjustment for tire size. No speed limiter, no fuel cut... maybe this is state specific? I am in Cali. my friends bone stock box hit 120 on same road..

I've hit 120 before backing off, I've been to 115 several times, So I'm pretty sure there is no Electronic Speed Limiter, now I can't say anything about drag.

assuming that there is a computer setting that restricts fuel i wonder if i can convince a Toyota/Scion mechanic to set it higher so that it wouldnt take so long for my xB to get to 115-120 faster hmmmmmmmmm

all i have is intake , header , exhaust , iridiums , ground wire kit , and engine damper. and I did every piece of work myself. no altered settings here.

I wonder if there is a difference with auto or manual trans? Mine is an auto and when you get to 110, that appears to be it.

Manual trans with tires larger than stock could make a diff.

Sounds like another call to toyota for info.

True it is a ECU Controlled Tranny, so it might be limited

That's a good possibility. Manual Transmissions have a lower gearing, and could possibly give the engine more room to stretch its proverbial legs. Or would it be the other way around???

well i can ride on 4th gear until im about to redline and i think i can hit 110 b4 redline or maybe more and that was b4 i had Intake, exhaust, 17" rims but after i got them on i made it up to 110 and beyond easier and faster

i got my xB to just over 125 on a flat road, all i have is a CAI and 3" cat back but when i did this i had only the 3" catback

a 3 inch cat back has lost you power.

the auto is ecu controlled.

hrmm... maybe i didn't do it right... but I was on the highway... LONG FLAT STRETCH. I had it in 5th at about 80, and decieded to push it (probably should have downshifted, but didn't),.... I am NOT even joking, but with the wind at my back, it took OVER 10 MINUTES to go from 80 to 100... needle hit and stopped at 100... backed off after about a min.... Car was already broken in too... had about 7,000 miles on it by that point... now it is at 25,000.

The reason I started this thread was I meet up with a mystery XB on the 417 here in Orlando when we both had just left the toll plaza. We were both doing around 60 and both punched it. Don't know what he (or she) had under the hood, but I have CAI, headers, dual exhaust and a Blits SC. We both accel'd to 110 very quikly and that was it. We were both at each others doors and could not go any faster. I still had lots of tach left, so I knew it wasn't the rev limiter. I was just currious if there was a speed limiter that kept the Xb from going any fast.

Be cool to find out who the mystery XB was and what's thier story. I was not able to pull past them and out accel him. It was night and best I could tell it was a camo xb with darker wheels and heavy tint.

Still not sure about the answer about a speed limiter either.

105 mph on auto,18", SRI,STRUP MUFFLER EXAUST,

your stupid for wanting to go over 110.
why?
1. you hit a twig your dead
2. you drive a box
3. if you dont hit a twig, refer to #2

I don't have any positive info, but I really think the 'speed limiter' is basically a tiny engine in a vehicle shaped like a UPS delivery truck... :D

haha i can get up to 110 pretty quick.... i wonder how much quicker can a s/c xb do it.....deng so basically if you were running me even if you pulled away at the drop i would have prolly have walked passed you like it was nothing haha....... hope i run into your s/c xb on da way down to FL for a road trip dis spring or summer it would b interesting......

i wonder what kinda twig you gotta hit to b dead? and for a box where pretty fast IMO even though we have no aerodynamics like it matters haha and that we onlee have like 100 hp

i can get up to 110 pretty easily too but its kind of scary feels like the wind is going to flip me over i can feel all kinds of pushing and pulling from the sides.

i wouldnt wanna test the limits of the car 125 is insane in a box a sharp burst of wind on a curve and they identify you by your teeth after they pull them out of a telephone pole.

you lower your xB and it become MUCH more stable.

That race with the other Xb was the only time I've been that fast in my ride and don't plan on making it a habbit, but when you are just driving along minding your biz and some other xb pulls up and whats to see what your packin, ____ happens. I definately don't like street racing and the dangers it causes and things like that should be taken to the track where it belongs and can be done safely. I was a bad boy for racing in the first place on the interstate, and will "try" not to let it happen again.....haha

Itsme, if you make it to central florida in april, we are having a big scion car show and swap meet at Old Town in Kissimmee (near Orlando). Please come by and check it out.

the mystery xb wasn't chris was it

I don't think so, at least he didn't say anything. Thought it might be Rubin, but he hasn't said anything either. If they knew me and my Xb they would have posted they kept up with a SC'd Xb. I was hoping it was SuperFa and at least I could say it was another SC'd Xb that gave me a run for it.

yea I know, But have you taken it to the track yet if you have pm your time I looking to s/c and I want to see the times. Do you have the templates still for the diamond plate?

i love the name Kissimmee, FL haha my family was there last year for vacation but i didnt go but all i know is that my dad had a problem tellin ppl that he was at Kissimmee, Fl haha.....i would like to go but i would have to find some ppl to go with me so i dont fall asleep on the road :P... i wanna race you at the track haha even though you should pull on me like crazy and that prolly wouldnt give me enough time to pull up on you haha not a long enough race

If I remember correctly, I read that ALL Scions have a fuel cut at 127mph. I know tC's max out at that speed, but I believe all Scions are set at that 127 limit.

So I got my auto xB with only cai to go to 120 down the altamont pass, yes its down hill but then engine never cut out, when it started going back up hill I let off so I dont die/get arrested.

Jeb, I do have a plastic template for the back that fits over the spare tire area and a paper one for under the hood. The ones that are for the headlights and front grill, James or Justin have those ones.

A quarter mile time? I'll have to attend your next drag night event and get that one. Whats the lowest time for an XB so far. (at the Superfa drag night event, not national).

Also, big meet at Coutesy Scion St. 25th at 6pm, please tell the team SuperFa and SD crowd for us.

Thanks

If I remember correctly, I read that ALL Scions have a fuel cut at 127mph. I know tC's max out at that speed, but I believe all Scions are set at that 127 limit.sure they do. is that why i've seen tc's break 135?

I've had Nikki's car up to an indicated 120mph, but I doubt it was really doing 120. Probly more like 105-110. All factory speedometers get less acurate the higher the speed. My F-150 has a cut-off at 98mph...my GPS says I'm really doin 93mph. I have 50k miles on it and the tread is about done for, so that would make a slight differance. Motorcycles are even worse. If you can even read the speedo it'll be way off.

As far as the quick xB...all I can say is that there are about 7 local SuperFa Nitroused boxes running around town now. The highest shot being run to my knowledge is a 50 shot, but a 35 would run all over a mild blown car like ours. I've provided smaller 17hp pills in a couple kits, and that's maybe what you ran into.

Chris's Camo is freakishly quick NA, but your car should beat him out.

We should set you up with a custom wet kit to run with the Blitz for the times you feel like being bad on the interstate.

I recently (last week after the show) ran a TRD blown tC with Nates car and walked away pretty easy. That was with a real fat fuel jet and a low bottle, too...surprised me.

Anyways, sounds like you had fun at any rate :evil:

See ya soon.

Once again...

I have an '04 Xa 5 sp manual. My speed is clocked by my pioneer AVDP gps system. My stock speedo will hit 120 for a second. GPS has my speed at 125mph. The fuel cuts off to the engine and the car will shut down. at about 115mph pump the gas and the engine will kick back on. I have done this numerous times. Granted I have done alot of work to my car. I will just throw that out there since the last time this topic came up in august I got a few questions how I was able to do this so easily or at all with the 1nzfe that is N/A.

F.Y.I. Here is the link on the repost.

Whoever said they hit 135 is a liar. The tC can't go over 127 without the car's computer being modified. Do a search. They are rev limited and the fuel cuts out at that speed. Trust me.

this one time, i got upto 90, then i went over a bridge, and my exhaust scraped the ground, so no, i dont do that anymore. haaahahah , but seriously, it happen.

I was so bored sitting here reading this and laughing so hard that i went out and tested out my xb its a 06 the only mod i have on the car is the TRD quickshifter which is gonna do NOTHING for speed and i easily got over 110 i actually got to about 121 or so...... thats on a factory 06 Xb with only a quickshifter!........ you be the judge if there is a limiter??? dont think so!

i dont think there is no limiter aside from the ECU's haha

I got up to 115 last week while driving through Kentucky. I was going downhill, but 115 is 115. :P

I am pretty sure the highest ive gotten is 115 ish, the other night i was pushing and had it pinned for a while and couldn't break 109ish.
go figure

Ill post a pic of me going like 120ish so then it is for sure there is no limiter!

yea i will to but ima do it my way ima jack up my car put it on jack stands then start pushin it up till i see a fuel cut off should be fun just hope i dont go flying off da jack stands haha

toyota also say's thet the speedo can be off by = or - 5mph so 120 on the speedo is possible, but the gps is a diffrent story. y have a bone stock 06 xa and have hit 115, so i beleive it is possible.

Actually, Toyota REQUIRES the speedo to be 3 to 8 MPH too fast at 100, per specs - that's the way it is designed...

http://tijil.org/xB_speedo_cal.gif

cool i did not know that. and i work for a toyota dealership.

I know my 06 xb with TRD exhaust and quickshifter has gone up to about 120 and it has no problem accelerating until I hit about 110, the last 10 are the ones that take a little time.

for me in my xa it was diffrent, i had no problems getting to 115. it felt like it would go faster if i wanted to.

turbo that $h!t

I've gotten my box to do 117 mph on the freeway going downhill and I've got an auto trans...

...and 117 indicated can be as little as 107 true with stock tires/wheels - even less if other size tires are used...

as little as. it could be more tomas. it could be more.

True, but it couldn't be more than 113 with stock tires/wheels. At speeds above 60 MPH the indicated speed will ALWAYS be higher than true speed with the OEM setup. Nature of the beast. :)
