anyone have a 0-60 time on the automatic tC? i know 7.5 has been posted as the 0-60 time but im pretty sure thats only on the manual and i know auto drives a bit different with it being the almighty slush box :p

thanx

 

i know someone out there has an automatic tC and can count time.......

 

I'd estimate 8.0-8.4

 

if you know how to drive an automatic from standstill you should be able to get a better than 8 second 0-60, crap my last car could do better than as an auto and it didnt even have close to the power that my tC has, though it did weigh less. I would say the auto could do it in just less then 8 seconds, like i said if you drive it right though....

 

so how do you drive it right?

i know of two ways that people do.
-rev it up in neutral then pop it into drive, which is very bad for the tranny, i know someone who used to do this all the time until he stripped his first gear.
-stay in drive, rev it up, and release the brakes. i would imagine that this was bad for the brakes.

anywho i'm studk with an auto for reasons beyond my control so please do tell.

 

i am not in anyway saying its good for your car but you at a stop downshift into L and hold the brake while slightly revving the engine then when going step off the brake and then shift into 2nd, 3rd, and then drive at the appropriate RPM, around 4k cause since it is still an automatic it will shift itself once it gets higher then that. I didnt say it was good for the car but the best power is around the rpm level a little higher actually but its hard to keep it there with an auto, and thats how to drive an auto. Though like i said i wouldnt drive around normally like that i do want my car to last awhile. Im just saying you can get a better 0-60 time like that. I would say like a 7.8 probably or 7.9 since the standard is around a 7.5.

 

I got 8.0 starting in "L" then 7.8 the second time.

 

I did 0-60 in around 7.5 seconds... the gear ratios are not that different... the TC's thrid gear is great... i dont go for that 5spd popaganda... learn to feel out the car and it doesn't make that much difference...

 

I have trouble beliveing that, how "scientific" was this run? The reason Autos are slower is not the gear ratios, but because of the power lost in the torque converter.

 

yeah it is kinda hard for me to believe that you got the same running time that the pros got with a standard in your auto. Like i said a 7.8 seems right but im not sure you counted that right to get a 7.5?? did you use a timer or just count or what, were you in a hill going down? either that or you need to start doing some professional driving there man and get some bank doing it!

 

It has to do with the torque convertor, but the gear ratios do make a big difference. I don't know the difference in ratios but I would imagine the first gear of the 5 spd is much shorter than the auto.

Remember, shorter gears = more power than with longer gears.

 

How much time do you think could be shaved off once a turbocharger is installed into an auto tC? I read that the TRD Turbocharger will push it up to 200hp...but how much higher will the torque jump to from 163?

 

The gear loss is between 3rd and 4th... I dont let the car shift into overdrive until it's
close to the red... try to drive one before trying to blast me... thanks...

 

Are you aware of a thing called power to weight Ratio? Or do you prefer to base everything on a single stat?

You guys are debating over tenths of a second when someones timing it themselves while driving? You do realize that your reaction time when you start/stop the clock could make any run seem good or bad, right?

I've never had a destination I was driving to that was only a quarter mile away or that I got to when I reached 60 MPH, so I guess I don't see the importance everyone puts into this. It's OK if people give flippant guesstimations, but as soon as someone who drives one gives his experience, he gets jumped on??? Go figure...

 

dizzytc...TRD is not making a turbo...its a supercharger...but yeah...im ganna wait for a turbo to come out...

 

yea sorry I know its an sc...i keep getting mixed up.

 

i did mention weight i said my last car weighed less then the tC, so even though it had less power it was still better than a 8.0 0-60 ok? i wasnt just talking about hp there read it better. And i wasnt jumping on you there man i was just saying its kinda hard to believe you did a 7.5 in the auto thats all im not saying its impossible though, i havent tried it myself yet, and untill i do i wont say anything more, i probably will try it though sometime soon

 

oh and i would also say that the SC if it makes the torque rating go up to about 200 also would make the car pull about a 6.3-6.5 0-60 around what the ion redline does because the curbweight, hp and torque would be around the same. Course if the torque isnt affected that much it might be around 6.7 or so.

 

Isn't there a speed chip that restricts the tC from being redlined? Isn't there a way to get around that...change it or disable it?

 

Ok, no arguing about auto tC 0-60 before someone posts a scan of a 1/4 or 1/8 miles slip with 0-60 on it, ok?

If Car and Driver (or who it was) 0-60 of 7.5 was close to truth, then 4A tC wil have 8.5 0-60 at most. tC auto is not some super sport auto tranny - it's a regular toyota auto tranny that's made for fuel economy, the gears are much longer, the acceleration is slower. 5-speed tC goes 70mph @ 3500rpm in 5th(!), Auto tC goes 70mph at close to 3000 rpm in 4th, so the gears are much much longer. Add sluggish auto shifts to it and general loss of power in a very complicated (compared to 5-speed) tranny.

So what are we arguing about? It's a generic toyota 4A, not some super cool m-series bmw SMG tranny.
