Haven't hit the limiter yet but the redline on the tack is 5900 RPM.
5.7 Rev Limit ?
Now I know the 5.7 makes [email protected] but does anyone know at what rpm the rev limiter kicks in?

Wouldn't condone trying, but I have seen 120 on the speedo, which it did with ease passing a farm truck.
Do you recall what RPM's you were turning at 120?Wouldn't condone trying, but I have seen 120 on the speedo, which it did with ease passing a farm truck.
Not that they know what they are talking about, but Car and Driver magazine listed the top speed of the 07 Tundra 5.7 as 107, which they claim is computed limited. You wouldn't be anywhere near redline in 6th at that speed. My tach shows redline at 5900 RPM - same as was listed by Car and Driver.
Rev limiter and top speed limiter are separate functions.

Yes the tach is clearly marked, or in the manual it also states this. I do not remember seeing a posted top speed though, other than 95 in third for the 5.7 or 91 w/4.3 gears.Not that they know what they are talking about, but Car and Driver magazine listed the top speed of the 07 Tundra 5.7 as 107, which they claim is computed limited.

Don't believe everything they post in those magazines, like reviews stating the 5.7 lacks passing power...
I was told on my '04 it was limited to 105, although I never got close. It ran out of juice at 90, so for me it was 90. I live in an very rural area were there are lots of open roads, many ranchs, few cars. Was busy looking at the road, but yes the speedo read 120. I was passing two farm trucks pulling trailers, so I was WOT longer than I realized, thought I was doing 90 or so and looked down. I will be more careful in the future, as I was very surpised how fast I was going as it did not seem like it. Hard to tell the difference in 50 or 100 in this truck. I have had other fast cars, but you could tell when you were bustin 100.
I believe it was still in 4th. I have had it over 107 several times to 110 in 4th. The 5.7 will easily break 100 very quickly and still be screaming.
I believe the speed limiter is generally correlated with the ratings of the tires. As my Bridgestone Alezo Duelers HL 275/55/20 are H rated = 130mph max. Although I have no intention of finding out if thats true. Seems the speed limiter should be the same for all 5.7's. Maybe I actual did get something sporty with my TSS option other than chrome and rubber(?). Also many of the reviews I read they were testing 4x4's with off road oriented tires, perhaps there is a difference in speed limit. Not sure, but the 107 is not true in mine. Again not condoning unsafe driving or speeding.
20's on 07 C/M rated at 106 MPH "R" speed rating for OEM 20's, just query The Tire Rack - Your performance experts for tires and wheels for your OEM tires, be safe and slow down just a tad!! ticket at 120MPH would be bad new to pocket book!!
I agree about slowing down. But I am utilizing a radar detector and very secluded roads, and it did not take long to get there. As I didnt redline 4th I wonder what the top speed really is? I doubt it pulls in 5th like is does in 4th. I wouldn't be surprised if on a track with the right tires it could do 130+20's on 07 C/M rated at 106 MPH "R" speed rating for OEM 20's, just query The Tire Rack - Your performance experts for tires and wheels for your OEM tires, be safe and slow down just a tad!! ticket at 120MPH would be bad new to pocket book!!
Mines not a C/M and the "H" rating and size came right off the tires on my D/C with Toyota Sport Series package. I am sure these are not the only 20's tires put on the '07 Tundra.
Seeing is believing 275/55/20 111H Bridgestone "alenzo"

The truck will do the speedo limit and then some,just leave it in 5th till it bumps the limiter.It will not up shift to 6th.How fast is that ?130-140 maybe ?
But remember the local law will calibrate your speedometer for FREE.

It is interesting that you can buy the 5.7 Tundra with tires rated at 130mph.
Much has been said about its 1/4 mile and 0-60 acceleration, but in my opinion its just as impressive 55-100+, which it can do well under a mile. This might be were the 5.7 can seriously embarrass other trucks. My previous 4.7, 4speed with 4.10 LSD hit a wall at 90 mph and slowly revved past that point and it did not feel like it belonged there. At 100mph the '07 is rock stable and feels like your doing 50, wanting more. Very impressive for a 5100lb truck. This diffinitely is a plus for the towing aspect of the 5.7.
Be really interesting if someone put a lower rear end, tuning chip when available, perhaps lowered it, some areo dynamic ground effects and v+ rated tires, and few performance MODs, be a highway sleeper.
Glad to hear ya gotta higher speed rated tires than i thought, it would be ugly one of those suckers flying apart and your eyes would be as big as half dollars and minus a seat cushion or 2!! I was trying to keep up with a 350 Z a while back and my 4.7L fuel pump limiter kicked in at 105 and i thought i had blown it up!! slowed to 100 and all was well and AZ DPS would have put me under jail if they would have caught me but between Laughlin and vegas not much out there!!
You guys made me curious about the tire ratings, so I checked mine.
I have the Bridgestone Dueler H/T 684(2's)
P275/65R18 114T
They have a T speed rating of 118mph
I was surprized they are that high. Now I am more curious about the speed and tach limiters. Someone needs to go to the track or dyno and find out. I don't plan on driving that fast, but it would be nice to know what the limits are for braging rights.

What I would give for a set of 3.73's right now
I know what they did for the LS1 F-Body 6 speeds :tu:

I thought Nevada didn't have speed limits? Perhaps i am incorrect on this. I generally obey traffic laws and have not had a speeding ticket in years (knock on wood). 90% of the Texas population lives east of here, so theres alot of desolate roads available west of here in this big state. My point was that the 5.7 has alot of top end, more probably than needed in 5100lb truck, and I have yet to see a posted top speed for the limiter(107?), so be careful passing, because it might surprise you.

MT didn't have speed limits until last decade, thats the state of Montana for those who didn't remember which state didn't have the speed limits until recently. Nevada does have speed limits however.I thought Nevada didn't have speed limits? Perhaps i am incorrect on this.

Sanosuke!
My bad Nevada probably does have a DPS but from Boulder City To Laughlin ain't nothing but homeland security and a couple coyotes probably!! Once ya leave Laughlin the AZ DPS guys have been getting there quota's filled from what i hear!! It slowed me back down a tad!!I thought Nevada didn't have speed limits?

I drove from Marble Falls to Big Bend a couple of weeks ago. On some stretches we did not see another car for 30 minutes and not one DPS, but the wife was with me and the Tundra wasnt broken in. There's some wide open spaces in West Texas for sure!My bad Nevada probably does have a DPS but from Boulder City To Laughlin ain't nothing but homeland security and a couple coyotes probably!!

Bull****. The speed limiter is 110mph. As the speedo pulled right passed 100, I though "this thing is gonna hit 120!" Then the limiter put a halt at 110.
You mean your speed limiter...Believe what you will. I have nothing to prove!Bull****. The speed limiter is 110mph. As the speedo pulled right passed 100, I though "this thing is gonna hit 120!" Then the limiter put a halt at 110.
As it is a 5100lb + truck not much point in going over 90 anyway, I believe that what cars are for. But this truck pulls strong over 100 in 4th. I justed wanted to warn the unwary before they draw local law enforcement or get in real scary territory. Just sharing my personal experience. No disrespect intended at all. Out of curiosity, what is the speed rating on you tires, if I may ask?
my truck hits the speed limiter at 109mph.
It pulls hard all the way there then just stops accelerating at 109.
I'm curious - the guys who claim to have hit 120mph, did you bypass the ECU for the speed limiter?
