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

 

i have not altered any settings. theyre mis-informed.

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.
