First and fore most. I do not condone speeding on highways! I did this on a safe, straight, not used back road that I found. Most will say take it to a strip or track, well some of us don't have the time to but need to feed the addiction.

Ok, so last night or the night before, I was cruising this road at 70 mph, had a biker in front of me doing the same, then an xterra flew by me passing me with a truck coming the other way. Biker braked and so did I so there wasn't a head on collision involving 4 vechs. and at least one death...that being the biker. So we are both ____ed and race after him. Well I as I'm flooring it they start slowing down so I do as well but before I do I see I was going 118, I was like cool. So tonight I went back there, made sure no one was around for the part I was going use and went for it...my car tops at 118 apparently. RPM was roughly 4700 if I remember correctly but it was neither climbing or going down(like hitting the rev limiter). It was like it just got stuck at 118 at that RPM and that was it. Car was handling great. I have a CAI on but I doubt that had any issue with it. It's an 07 with an automatic tranny and almost 10300 miles on her so she's past her break in period so no worries on that. Does anyone have any clue as to why she wouldn't go pass that? I mean hell it had another 1500 RPM to go, it seemed like it might not have been pulling in more air/fuel to keep going, so would that be an ECU thing? To make sure it didn't hit the rev limiter I kept it there for about 20 secs and it did nothing. She shifted to third at 70mph, 4th at about 110-112 I think and then just after that she got to 118 and sat there. It's to my knowledge that electronically limited to 127 and gear out at about 134, may that be different for automatics? Any one have suggestions? Thanks a million.

*UPDATE*
When back out on that road again. Staked it out, made sure no one was around and car was fine then took her for the speed test again. Made sure my A/C was off, windows and moonroof were closed, radio turned off, and cruise control off. Also went the opposite way on the road since there was indeed a slight incline in the direction I was going the first time. Sure enough, she got up to 122 before I had to start slowing down for an approaching corner. RPMs were still climbing so all is good thank God :bow: :pray: So I think it may of had something to do with either me having the A/C on since its hot as hell out here in NV, the windows and moonroof open :P, the cruise control button on, or the radio being on. Or it could have been a mixture of all or some. I personally think it was happened because the A/C was on drawing a few horses from the motor and the windows open increasing the drag on the car, coupled with going up a slight incline. Thanks for the support to those of you that actually did try to help me gather some thoughts on the matter. I spoke with a tech. at another dealership about it, none of the Scion techs knew what speed the speed limiter was engaged at so I was hinting around with the guy on what Car and Driver said online. Then told him my problem. His suggestion was the speedo could have been off, but to take it to a dyno and they could tell from there if it actually does reach the speed. He was really cool about, he races his cars and stuff too so he didn't care, we talked for like 30 mins before he was called away, but he was cool as hell. So, I did it my way and I don't think the speedo was off. Once again thank you guys! :bow:

well a couple months ago, i hit 125 but couldnt get the last 2 mph...

maybe cuz you have an automatic, it cant put down enough power to get up to 127. you should try going downhill or something, and make sure theres a tail wind lol

well, the manual tc's are limited to 127 mph and gear out at 134 mph, but i'm not sure about the autos...

shifted 2nd at 70mph???

So drax, do you think it hit its "gear out" point? I've never experience gear out yet but what I was picturing is going fast enough to where the gear actually breaks...like in those motion toy cars that you push across the floor and keep going. Push too fast for the gear and you break "strip it". That would suck if it hit gear out with another 1500 RPM to go LOL should've gotten a manual...if only I knew how to drive them. :loser:

shifted 2nd at 70mph???

WOW, sry, typo, I'm editing it now :P meant shifted TO third from second at 70 mph and shifted TO fourth from third at about 110-112. sry

should've gotten a manual...

you hit the nail on the head.

my auto tc did 125 :D

I have an 07 auto with 18k miles and I've gotten it to 125-126 on more than one occasion without any problems.

ive topped my auto at 75mph on the freeway! :D










seriously i did!

:cry: So not fair! I mean it's not like I need to go that fast, but now that I can't I want to know why :tap: I'm not getting my full 18k that I paid for on this thing :rofl: Should I talk to my dealer...quite sure they are going to want to know why/how I tested that but other than that I don't see them fixing it since it's completly driveable. What worries me is that fact that it still had so much room til redline. If you guys got there in your autos then what would cause mine not to? I'll drive the road the opposite way tomorrow after I stake it out again and see what I can come up with. Maybe there was an incline that I couldn't tell from inside the car. Would having the aircondition on low (as on just one bar) be enough to drop it that much in power? I mean Matt suggest it can't put down enough power...but it wasn't even trying to put it down. I'm kind of a noob still but to me it seems it wasn't getting enough air/fuel or it's tranny related.

Um :question: how exactly did you "top it out" at 75? were you going up a steep incline???

Do any of you autos have any mods? IE Intakes, exhausts, headers, turbos? I only have intake and exhaust...think maybe the MAF sensor would play a role in it? I've been searching all evening and still nothing :tap:

Dunno why you can't get passed 118. My manual tc had no trouble getting to 120mph. I was actually surprised how good my car drove at triple digit speeds for a mere four banger that it is. I need to fix my engine asap so that I can have my beastlike performance back :)

I wouldn't worry about something so minor. You don't need your car to be fast passed 100mph because driving at triple digit speeds is dangerous. Especially in our econobox cars that were not made for those kind of speeds.

If you really must get passed 118mph then I think an injen cai would let your engine breathe a little better.

Doubt it, it's prolly the gear out point. Mods won't increase that, merely decrease the time to get there.

Yes I know its dangerous and I said I don't do it all the time, just once in a blue moon type of thing. Now that it's not going pass 118 I'm worried and kinda peeved about it. If it doesn't go pass it tomorrow if I get a chance too then when it goes in for maintance Friday I'll add it to their to do list. I mean seriously, I want to turbo my car but what would be the point if its something not engine related and it doesn't go pass 118. That's just a waste of money! And my intake is already the Injen CAI so I don't see how getting another will fix that :P sry...sarcasm, maybe the filter needs to be cleaned, I've been in two sand storms and you can kinda see the sand in the little groves of the filter but its not a lot, maybe enough to mess with it though. Anyone else got suggestions? :pray:

But others have gotten there in their auto's :lalala:

Could be a lot of things, but I doubt it's the car, more likely the conditions i.e. gas, temp, A/C, altitude. I donno what effect those would have on the car, but I'd be willing to bet it is nothing engine related if others have gotten there.

what year is your car? they may have changed the 07's ecu

joke foo!

I know you said you don't do it all the time. But unless you're racing your tC(on a strip or track that is), you DON'T need to go past 118! And the dealer will probably look at you and ask you why you want it to go over that. But even if they did fix it, they don't have a dyno to test it.

I don't know...Mines an 07 and brian and redline both have autos as well and have gotten there. My choices so far is clean the airfilter and turn the a/c off, or take it to the dealer. The only issue is that it maxed out at 118 before I've put the Injen on it. It was like 2:30 am in morning on the way to work and I wasn't paying attention to it not moving, buy yeah come to think about it, it did it before and after the CAI, and that road was actually kind've a slight decline on the freeway. So, that narrows it down to a/c being on, something weird with my ecu, or engine/tranny related. Oh, all I use is 91 octane for gas, temps have been roughly 95F. On that one morning probably about 60F or lower though.

I don't condone speeding on public roads, but I'm not one to talk. I have an 06 with over 32K on the odometer, and she still has no problem reaching the speed limiter. I have reached it stock and modded. Like I said, it is stupid to go that fast, but when your taking a long trip and you just kind of want to get there faster, the road is open, and you know that your car is capable ( i.e. good tire tread, regular maintenance, it is past break in period). For a good 10 miles I was bouncing of the speed limiter, man that was a lot of gas wasted. I have made it from Orlando to West Palm Beach in about 1 1/2 hours roughly 180 - 200 mile trip one way. I try not to speed anymore too many tickets, waste of gas, and really dangerous for yourself and others. On the other hand it can be really fun. Later all.

You said you had an Injen CAI on an O7 tC, out of curiousity, where did you get it from and do you remember the part number?

http://www.killertc.com/product.php?productid=16685&cat=256&page=1 Just click the drop down box and select black or polished for 07 its 259.00, 10 bucks more than the 06 model.

We hit 130 in my brothers tC last weekend. But we have full standalone with the rev limiter up just a tad higher. Even before that it wasnt a problem getting to 127.

The 07 ecu's are diffrent so they will definately respond to mods diffrent and run a slightly diffrent program because of can scan.

If the ECUs are different then how did Brian get there?

I have an 07 auto with 18k miles and I've gotten it to 125-126 on more than one occasion without any problems.

Forgot to mention my engine/drivetrain is completely stock (as of now ;)).

Thanks buddy :D So...does anyone know of a tactical way of asking the dealership or service advisor on why my car wont go above that?

just tell the dealership you have a deathwish and want to make sure your going as fast as possible so that WHEN the accident happens (not if) that you want to make sure you are going fast enough that there will not be anything left of you to revive...

Wow.. talk about maturity from a 33yr old :tap: Thanks for not reading the whole post apparently, and I've already figure out what happened, and I've already said it enough times... I DONT race the damn car everyday and I've only been past 100 four times so far and completely safe when I do so! I will put the update as to what I think happened in the original posting.

yeah, being over 100 four times on a public road is 4 times too many though still ANY way you look at it.

Very true, and I completely agree with you. Your previous comment just wasn't exactly called for. Now that I know my car is not broken I won't do unless its on a track or a designated area. I mean in all honestly, I'm paying 18.2K for a car that could have possibly had something wrong with it. If everyone elses goes to 127 and mine goes to 118, don't you think I'd have a reason be concerned and peeved about it. Don't know about you but I'd want it fix. But still, I agree with you on not doing that on public roads, that's why I kinda lucked out with this whole scenerio orginally happening on a back road away from property, houses, people...you name it. It's not used alot at all, it just happened that there were 4 of us and the one guy decided that he would like to make a 4 car accident occur. That lead me to finding this "issue" I thought I had, and decided to check it out. So the next time and this most recent time I drove the road back and forth twice to make sure no one was around and that there was nothing in the road that I could hit and make it lose control. I was as safe as possible for being a back road, not a full public road, and not on a track. Thank you for your concerns though :clap:
