Tacoma 0-60 in 4 seconds!

Very cool little camera!

You really aren't going to give the drums a spin? You aren't even curious?

 

This is not an accurate way of getting a 0-60 time. Run the truck with a vbox to get an accurate 0-60 time. Trying to figure out a time from a video is highly inaccurate.

Also, if you got to 60 mph in 4 seconds, it took the truck another 4 seconds just to pick up another 22 mph. That doesn't make any sense.

Good runs, and I really mean no offense, but you cannot claim to run 0-60 in 4 seconds unless you actually measure 0-60 via GPS. Again, good times from a 4x4 double cab!

 

How do you do the tuning?
I have my other truck tuned on a dyno to set all the stuff under load and to keep the A/F in line.
Do you use a hand held to tune it?
Just wondering.

 

It is an accurate way to measure 0-60.

Again people, go back to the first post and look at the time slip. 60 ft time is 1.8 seconds. This isn't rocket science. The truck is a beast off the line to 60 mph. It slows down top end because it weighs over 4000 lbs and it has the aerodynamic properties of a brick house.

I am not the only tacoma able to get under 5 second 0-60 times.

 

Damn

 

Its fairly close, the time slips tell the story

 

One needs to measure location and speed via GPS to get an accurate measure of acceleration. There's no other accurate way.

Acceleration IS science, and that's why there is a specific way to measure it. I'm sorry, but a 15 second car can get a 1.8 60 feet with sufficient traction off the line. The 60 foot time has nothing whatsoever to do with the 0-60 time.

Did someone else get a recorded 0-60 time in under 5 seconds? If so, do you have a link to the datalog by any chance?

Again, please do not get me wrong, I like to see the results of your truck's acceleration down the 1/4 mile. It's just not possible to extrapolate any further data than what is printed on the time slip.

 

Im not one who knows much about calculating 0-60 times or anything however here is an interesting formula...... I found this calculator on the corvette forum and plugged Will's data in from his timeslips and it seems to correlate.

when you plug in 1.824 for his 60', 5.365 for his 330, and 8.34 in the 1/8th, the results on the table show that he would be going 82 mph at the 1/8 mile mark....... which is like .24 off of his posted 1/8 mile speed on the slip. It also shows that with that data in there its roughly 4.42 sec to 60mph.

heres the link, may not be totally accurate but seems to complete the equation.

Please don't misunderstand, I'm sure his truck can get to 60 in under 5 seconds. I just find terrible fault with trying to count the 0-60 time by watching a video.

Nowadays, even cars that get to 60 mph in 3 seconds flat feel slow.

 

no, i see what youre saying. I just thought it was an interesting calculation myself so i figured id post it up.

 

lol, oh man. We need to start from scratch here.


GPS is regulated by the Gov't to only be accurate to within a few meters. There is also quite a bit of time lag involved in the process. I hope you are not confusing an accelerometer with GPS. These are two different devices.

Now, the X-1 data logs that I have seen from Xrunnit and Deathshadow on XRU have been within hundredths of a second when comparing to video of the actual gauges.

A 15 second car will never rip 1.8 60 ft. It just does not have the torque o do so. It doesnt matter if it has perfect traction. The only way to run a 15 after a huge launch like that is to lift at the end of the track or run out of gears. You would know this is if you had ever been to a track yourself. Acceleration is not linear

The 60 ft time does affect 0-60. You must understand that when you race from a dig, the better the launch the more huge momentum you will have when going into the next gears. In other words, the fast your 60 ft time, the fast your time to 60mph. Not to get the 60's in the names confused, but you can in fact compare and relate the two figures. Again this also explains why my truck is doing so well in the et department, yet is only going 101.9 mph at the end of the track. Maybe that is what is tripping you out here. Most cars that do 0-60 in 4 in your Road and track magazines are running mid 12 second 1/4 times. The thing they never show you though is how badly those cars are spinning off the line. As they say in drag racing, spinning ain't winning.

The only real 100% way is to use calibrated laser beams over a predetermined distance (aka the track), however a video that is within a few hundredths is accurate enough to say this truck accelerates to 60 in 4 seconds. I'll give you 4.1 if that makes you feel better. Heck there are even online linear(read too high) calc's that show me at 4.3 seconds.

There are several members on XRU who have run very similar 0-60 times, here is one example

Thats my last response to you in this thread. If you still cant believe me or understand after that, then I don't know how to help you understand this. I will not be called a liar again. I am not trying to deceive anyone on this forum or anywhere else. My truck has an amazing launching capability and thats all there is to it. Come to Arizona and I will show it to you.

 

Awsome Super Werty! I follow you on XRU, 12's here you come.

 

I'm still hung up on why that isn't an accurate why to measure 0-60 times. At the beginning you're not moving (zero) and the speedometer measures instantaneous speed. When it hits 60 you're going 60mph. So, time between going 0 and 60mph, would indeed be your 0-60 time would it not?

I do fully understand that wheel spin could factor into a false speed reading but not with 4WD engaged.

 

Im confused now too. He says he thinks my truck is able to go under 5 seconds...well guess what! that would be 4

Yea a video isn't going to be dead on, within .000000001 seconds. But its going to be within a few hundredths of what a laser can do for you. It's going to be as accurate as it gets. Even if somehow it was off a tenth of a second, that is so close its not even funny.

Im starting to think this guy is just trying to start a fire here.

 

Nice times Werty!

You look like a black Stigg in your avatar

 

I told you that I wasn't trying to bash you from the beginning. It's just the method of gathering data was too flawed IMHO. I take it, you're not an engineer, right?

A tenth of a second is a huge margin of error. An acceptable margin of error would be in the thousandths.

Not in the least, sorry for going off on a tangent. I'm just glad you were able to admit that counting time on a video does not make for an accurate basis for claims.

Again, good times, the truck is pretty quick for what it is. Please don't assume someone who is questioning you is automatically trying to attack you. I'm just pointing out what should be obvious.

 

It's not flawed at all. You record a correctly working speedometer with a correctly working camera and you analyze the time down to the hundredths of seconds and you get 4 seconds. It's 4 seconds. I don't care what you say, it's 4 seconds. I am not admitting anything for you. A GPS is not the right way to measure acceleration. A laser will not show a different time unless there is something wrong with the speedometer or laser.

You are still wrong.

 

amazing

 

Ok Reid... you've made it VERY obvious that you don't have much drag racing experience at all, and I question most points of your logic. And you will never get a 15 second car to pull a 1.8 60' without stomping on the brakes at the end.

Most 60' times are within 13-15% of the ET, if they aren't then there was problems with the run.

Read my responses in the red.

Something to keep in mind that the printed MPH of the 1/8 mile isn't how fast he's going at the 1/8 mile. Both the 1/8 mile and 1/4 mile MPHs are the average MPH over the trap (60' before the the marker). Meaning the 1/4 mph is his average speed for the last 60' of the 1/4 mile, same with the 1/8mph. That calculator is telling the estimated speed most likely based on a linear acceleration and a static point in distance.

Vehicles never have linear acceleration, and in Werty's case not even close because of the torque curve of the TRD blower, and the lack of aerodynamics of his truck.

This is right.

Even with wheel spin, it is easy to decipher tire spin, especially if it is enough to make a drastic change in the ET.

See responses in red.

 

I for one will accept the 4 sec. 0-60 time.

There are enough factors to allow it to be there.
Other things can change either way.
I have a done a little bit of drag racing.
The atmosphereic conditions on the day of the run can be a huge difference. Espicially with a blower.

Track prep also comes into play.
I was out there the week before with some friends. very cold ( for Phoenix ) track. Very little VHT on the track. It is a test and tune nite so anyone that pays and can pass tech can run.
This includes people that are learning by doing.
I love following the fellow that drives his street car through the waterbox and does a burnout. then as he goes up to launch he is dripping water all the way to the 1/8 mile.
Many factors to include here.

Anyhow if the track has a fair prep and the air density is good I am sure it can pull off a 4 sec. 0-60.
