I hate cars

I finally got to do it after my first attempt that got interrrupted by a highway patrol. I had nearly 20 miles of straight downhill freeway in front of me with nearly no traffic. Tires were at 40psi and Z-rated so I went for it. Didn't take that long to peg the speedo since this was a pretty good grade. I hit just a hair north of 160mph with it still barely climbing and backed out of it. Previous best on flat land was ~152mph. This is indicated and I'm sure the speedo is off by a few mph at that speed, especailly with my .10" smaller diameter tires. Regardless of actual speed, the computer saw over 160 and didn't cut power.

lol.... brush up with the highway patrol, eh? howd that work out? you get a ticket?

I know you're not on a motorcycle, but keep it off the road...

I hate cars

First attempt last month I flew by a highway patrol approaching 140mph in the same spot. He must've been sleeping...

dude you need a vid or I wont bite, TLFourPlay maxed his TL-S at 150, and which is it rev limiter or governer I am still wanting to know

I hate cars

I watched that vid and I'm still not conviced it was either. Regardless, why would my auto TL let me go 160+ and the TL-S is governed.

there is only one way to find out, I am going to take my tl-s and find out tonight lol
I will probably chicken out

Probably 06 TL Auto doesn’t need limiter because it can’t go faster than 156 mph on a levelled road. On the other hand 07 TL-S 6MT can and they introduced limiter. Most German cars are electronically limited at 156 mph or 250 km/h.

csmeance

I think the governor may in the form of a RPM limiter. Since the TL maxes out it's RPM's most of the time to get up that high, it might be just hitting the RPM limiter.

Ehh...

Your mother chiming in here..

Please tell me why and when we ever need to go above 100mph.

I hate cars

Very true. Mine did an indicated 152mph on level ground and stock speedos are usually optimistic at that speed.

I hate cars

Most of my street racing friends grew up to be highway patrol.

the computer never saw over 160, only your needle did. the same thing happened to my last car, larger rims but way thinner tires, so it was smalelr overall.

bad thing is, you "put" more miles on the car then you actually do AND your speed goes "up" cause of the smaller diameter. at speeds that high, it is a noticeable difference.

I hate cars

The computer speed is based on wheel rotation speed, not actual mph unless it uses GPS and I highly doubt that. With the smaller tires the speedometer AND computer are off. In fact, it's safe to assume they use the same VSS. I may not have been going over 160mph but the computer thought I did which is the point.

Not so sure about that.

TLFourplay's top speed runs hit the Redline (rev limited) at ~152 in 5th gear. He hit ~152 in 6th gear with plenty of room before the redline.

I Hate Cars: What gear and what RPM when you had ~160 indicated?

Bearcat94

Should not matter with respect to a Top Speed Limiter. Whatever the computer sees (i.e. indicated speed), will trip the limiter, regardless of "real" (i.e. GPS) speed.

I went 140 on a rural Califronia road.

Exactly. Basically at 150mph in 5th gear I am running about 250rpm's less than redline, and at 150mph in 6th gear I am running about 5200 rpm's. If drag wasnt an issue the car could do 198 before being "redlined" in 6th gear. I dont really know why the hell an auto TL would not be limited and a Type-S would. If that is in fact the case than maybe its because a stock TL-S has the power to do those speeds and a stock auto 3.2 TL wouldnt realistically have that much oomph to surpass 150 on its own. who knows though. All I know is I proved that the 07 TL-S 6spd DEFINITELY has a fuel cut off at 150mph. And that was when my needle hit 150, I have never been over 150 with my stock 17's or my RJ 19's.

Dude I can't wait till someone cracks the ecu... acutally let me take that back cuz then tlfourplay will do 198mph

3rdGenHybrid

im not sayin that your wrong or anything.....but i had my TL and TL-S both up to 155 on flat land....no hills....the TL is an 05 AT....and the TL-S is a 6spd....the only thing with the auto is the longer gears....but still the 6spd hit 155 alot faster than it did in the 5at....(derrrr bigger motor...shorter gears)

Well bosss I dont know what to say. It just doesnt add up. Take a video of it or a pic so I can see. It just wouldnt make any sense that whether I have my 17's or 19's on that I have NEVER been above 150mph because the computer limits it, and yet you are saying you have. I am not saying you are wrong either, just sayng the facts arent adding up. I submitted conclusive evidence that the TL-S HAS a governor.

3rdGenHybrid

oh it definately does have a govenor....i agree on that....next time i get up around that speed...ill have a buddy snap the pic....at 150+mph i dont wanna whip out the camera and start clicking photos..hahaha

Yes... It's called the wind.

See I hate dumb crap like this. Gets me all fired up inside. Some "person" was arguing with me a while back that TL's are drag limited and dont have governers and when I posted my top speed vids SHOWING the car dipping down each time I hit the governor and also pulling very hard to 150 he didnt have anything to say. Either prove it or stop talking about something you dont know about. The TL has a governor. PLEASE prove me wrong and take a vid of doing over 150mph. How the hell would every TL be magically drag limited to 150mph....

I hate cars

Well, since I've been 160, I would say it's not limited to 150...

IF I ever do it again, maybe I'll take a picture but not likely. This was the 15 outside of Vegas and I really don't feel like going to jail or killing myself or someone else. I've already proved it to myself. You can believe me and try and figure out why my car is not limited and yours might be or you can not believe me and feel secure thinking yours has a limiter.

One point to bring up is I've been 152 on flat ground before. The speed would hover around 150, drop a few mph, back up to 150, and finally topped at 152. At those kinds of speeds all it takes is the smallest undetectable incline or gust of wind to drop you a few mph and make it seem like you've hit a limiter.

3rdGenHybrid

bro...your going off the fact that your car did 160 on a downgrade....i could drop your car off a cliff and make it do 200.....the car will cut fuel or spark(which ever one honda uses..) before 160....but since gravity is pulling your car down hill...and u have all that momentum pushing up behind you....with a big enough downgrade....you could probably hit 180....we're talking flat land...

I hate cars

Not even close. Do you have any idea how steep of a grade you would need to do 160 without hitting the gas? It would be almost straight down. Besides, I didn't hit the brakes to slow down, I let off the gas and coasted down to the speed limit.

It's not true. If you're governor limited at a certain speed, the ECU still won't let you go past that limit even if you go downhill. Unless you're on a very very steep downhill.

I've touched many cars speed limiters (mainly rentals) while going downhill and I can tell you that when the ECU cuts the fuel delivery, you're slowing down. No question about it.

I don't have pics or video to prove it, so if you don't believe me, it's your call. I once took my car to more than 155 mph (indicated) and I didn't feel any governor limiter kicking in either. My car is 05 with 6MT.

3rdGenHybrid

Actually...not all cars cut fuel delivery...especially turbo cars....the last thing you want is to lean out a turbocharged motor....

i agree....on flat land...if your car cuts off fuel/spark...your car will slow down...but this guy is talkin about downgrade...

if the car does cut fuel...and your doing 155 on a downgrade and lets say you put it in neutral, 3500lbs is pushing you down that hill....even with resistance...momentum will still "push" you....so now your "free wheeling" at 155mph....and gaining more momentum...so cuttin fuel wont do anything....go try it....you'll go faster on a downgrade then you could possible go on flat land....

fsttyms1

At those speeds you would have to be going almost straight down for gravity to pull you faster. Wind and Drag are very powerfull things to over cum and a small hill wont do it.


But i can tell you hondas has some lazy limiters. The 2nd gens are supposed to be limited to 149 and i was clocked at 157 by radar (friend who is a cop)and my limiter never kicked in while others have had it kick in at the correct speed

I hate cars

The only thing in that entire mess you wrote that is remotely true is that you can go faster on a downgrade than on flat land.

I've been on hills with twice the incline of the one in question and the car wouldn't coast past 90mph.

When I let off the gas STILL ON THE INCLINE, the car lost speed very quickly.

How can you possibly think an automobile will coast at 150+mph on a 6% grade? Maybe I could've hit the revlimiter in 5th gear at 200mph going by your logic.

I did this on an incline because the TL does not have enough power on flat land to push it to 160. My whole point was to prove that my car does not have a limiter at 150 which I did.

Ok this one time I coasted down an incline at 40 I was doing 10 over... lmfao

Dude we are like that guy in the bible see to believe lol

Tlfourplay showed me that rev limiter is at 150 so honestly without proof who knows

Dude I am done with this thread. People like you really get to me. I can kinda see that maybe you are just trying to explain it to me but you also have to watch the vids I have made. I drove the autobahn all the time for 7 months and almost every time hit the limiter. I dont need a petty lecture that maybe its the wind. I had a 00 ford focus, limited to 108mph, had a 94 sentra limited to 120mph adn a 95 GMC Sonoma limited to 95mph. All feel the exact same when they hit their limited speeds.


I appreciate that bro. I mean I honestly dont think its too hard to notice the speed limiter kicking in on my vids. Although its not the rev limiter, its the top speed limiter because in 6th gear I am running 5200 rpm's. I think thats what you meant. I dont want the hate cars dude to misconstrue it though.


In closing all I have to say is that 07 TL-S is speed limited to 150mph. Also car and driver has always posted that the TL is limited to 152mph.
Regardless of rims I have on, going uphill or downhill with or against the wind my gauge has NEVER went beyond 150mph.

Formula 350

IIRC there was a discussion on this back when... the 04 was 'supposed' to be limited to 155... don't know why they would change...

Formula 350

You are so wrong in this... the drag of the wind is SO high that you will INSTANTLY start to slow down if you do not have the engine keeping you at that speed... no incline is enough to overcome this drag, even going down a mountain...

Man I don't even think this is worth discussing... I mean TLFOURPLAY maxed it out and his is worked... I mean the guy put all the mods available into the 07... so no words to that
